Have a question? My team and I are happy to hear your questions and get you answers! When you type a question, it shows up not only on that experiment but also here so you can easily find your answer. You'll find question boxes at the bottom of every experiment in the program.

Question: from Sara Belik about the Conversion Charts experiment :

I'm using Christian Light Education science is on page 43 to 51 of the document https://s3-us-west-2.amazonaws.com/prod-clp-files/public/documents/6861/original/2016-2017_Elementary_Scope_and_Sequence.pdf would love to match some experiments from your curriculum I have a Kindergarten student and a grade 4 (doing grade 5)!

Question: from Colin Stout about the Burning Sulfur experiment :

Thank you!!!

Answer:  Hydrogen Peroxide

Four grams of sugar is equal to one teaspoon... does that help?

Answer:  Burning Sulfur

The C3000 is included with our Science Mastery Diamond program. You can also purchase it separately usually at a toy store, but make sure it's the one from Thames and Kosmos.

Answer:  Humming Balloon

It's more likely that the hexnut is a bit sharp and made a small tear in the balloon. Maybe file it down on the edges and try again?

Question: from Robert Short about the Humming Balloon experiment :

I tried it again. My humming balloon got to a high frequency I think, and the balloon instantly popped again.

Question: from Robert Short about the Humming Balloon experiment :

I spun a hexnut in my balloon that was bigger than the one you used in the video and it popped. Is that because I hit the natural frequency of my balloon? -Rob's kids

Question: from Carrie Burkett about the Barrel Roof experiment :

We looked through the comments - and tried again...SUCCESS!

Question: from Lisa Pearson about the Hydrogen Peroxide experiment :

Wrong page, sorry. I thought I was looking at the "Making Sodium Hydroxide" experiment.

Question: from Lisa Pearson about the Hydrogen Peroxide experiment :

I don't have the Chem C3000 kit or the measuring spoon that comes with it. What is an alternative measurement for the sodium carbonate and calcium hydroxide in this experiment? Either teaspoons or grams would be great.

Question: from Colin Stout about the Burning Sulfur experiment :

where do you get the kit?

Answer:  Detecting the Gravitational Field

Gravity is a force that draws objects together, so there's no real pushing or pulling. As humans, we are attracted to the Earth because it's the closest, most massive, object to us. The effect of gravity lessens with distance, but it's never fully gone. So as humans we are probably impacted by the gravity of the moon, the sun, and more. And although some think there is no gravity in space, that is not true. Gravity may reach near zero far away from massive objects in space, but you are correct that it's always there.

Answer:  Science Teleclass: Light & Lasers & Holograms

Oh no! I'll have my team get in touch with you.

Answer:  Electrolytes

What a great solution! Thanks so much for the tip, Kathy.

Question: from Robin Wu about the Can Fish Drown? experiment :

Hi Aurora, What do you mean by "air" since we learned that "air" is mostly nitrogen- 70%+ and some oxygen, etc. In this experiment, if you were to say that the released bubbles are air molecules, do you mean there is some nitrogen molecule in the bubbles? Or since the tube started off with water, H2O, we are to assume that the bubbles are made up of hydrogen and oxygen molecule?

Question: from Kathy Humphers about the Electrolytes experiment :

hi this is kaseyhH {I am 11 years old} me and my mom could not find LED lights so we used Christmas lights, and they worked great. So for you who can't find them use Christmas lights

Question: from Marla Ramsum about the Science Teleclass: Light & Lasers & Holograms experiment :

I just opened up the physics of light and lasers and my key chain laser isnt working

Question: from Tamara Howard about the Detecting the Gravitational Field experiment :

Is there gravity everywhere? I'm just making sure

Question: from Tamara Howard about the Detecting the Gravitational Field experiment :

Does gravity also push down?

Answer:  Salty Battery

I'll have my team get in touch via email!

Question: from Linda Griffith about the Salty Battery experiment :

can i have acces to salty battery

Answer:  Mass is Conserved

Mass conservation tells us that nothing can be created or destroyed. Instead, the atoms of mass are rearranged in a reaction which results in something a bit different than what we started out with...but the sum of the mass-energy is still the same. In the example of something burning, let's think about a wood fire. There is mass in the wood and also energy in the form of chemical energy, which is potential energy prior to being ignited. Once it's set on fire, a chemical reaction - combustion - begins to take place and the energy is converted into kinetic energy. There can be a considerable amount of kinetic energy (heat and light) as the mass of the wood is converted. The combustion process requires oxygen in order to burn and gives off carbon dioxide, water vapor, heat and light. However, although the wood is burning, nothing is really created or destroyed. The wood's atoms are all rearranged and recombined and changed into different forms. I hope this helps!

Answer:  Cold Light

It's up to you! I would definitely go for it if she's interested. If you decide to proceed, please have her do so with adult supervision.

Answer:  Is It Alive?

Sure! Check out Unit 6 on Sound. Lesson 1 is on Vibrations: http://www.sciencelearningspace.com/unit-6-sound/ Happy experimenting!

Question: from Cindy Soderlund about the Cold Light experiment :

This experiment was listed in the 5th grade section, but at the top of the Cold Light web page it says "This experiment is for advanced students." Do I skip this experiment, have my daughter just watch the video, or proceed with the experiment?

Question: from Tracey Harrigan about the Is It Alive? experiment :

Do you have any units that have do with vibrations,etc?Thanks!

Question: from Colin Stout about the Mass is Conserved experiment :

How is mass (once it is energy) not burned? once it is consumed, the energy is no longer there, so how is it not destroyed mass?

Answer:  Special Science Teleclass: Geology

Yes, that's absolutely what I'd recommend: simply watch and follow along first, then go back and do the activities once you've watched the class all the way through.

Question: from Marianne Reed about the Special Science Teleclass: Geology experiment :

What's the best way to do this with a 9 year old. Should we watch it all the way through first and then go back and do what you are doing in the video (pause it and do the activities you are doing) and then continue. What do you recommend.

Answer:  Ammonia

The balanced equation should be CuCl2 + NaHSO4 = CuSO4 + NaCl + HCl.

Answer:  PVA

I don't recall green slime or sand being in one of our product kits. Are you sure it was from supercharged science?

Answer:  Sky in a Jar

That sounds really neat! Thanks for sharing your results :)

Question: from Lisa Pearson about the Ammonia experiment :

What is the equation for the addition of NaHSO4 to the CuCl solution?

Question: from Marianne Reed about the Lava Lamp experiment :

I like that if you put the oil on top of the water, add the salt and then add blue food coloring drops to the oil surface, if you look directly down on the surface of the water (through the oil) you see sparkles that look like the night sky full of stars. From: Sky

Question: from Heidi Boender about the PVA experiment :

Hello, A couple of years ago we had our experiments kit in the mail. We received a green package of sand in our slime kit. Which slim experiment is this used for? Thank you.

Question: from Melanie Gonzales about the Sky in a Jar experiment :

We colored the flashlight tape with areas of blue, red, orange, and green sharpie and when we shined it through the bottom of the glass, the colors separated out in the water. Blue, then green, then orangeish yellow and red towards the top!

Answer:  Rainbow Shadows

Sure - give it a try! Permanent markers would work better.

Question: from Marla Ramsum about the Rainbow Shadows experiment :

Do Blue, Green and Red markers work for coloring too?

Answer:  Special Science Teleclass: Biology

Oops, sorry Kenny! You're right - I edited that part out by accident because it was something we did in the live class before we actually started the class officially. All you need to do is do is look at the critters for question #20 and take your best guess as to what they are. And then take a look and see how you did! It was just something we did for fun at the start of class, we didn't do a lab or anything with it. If you'd like more details about this part in particular, jump to the Unit 16 lesson Microscopes.

Question: from Kenny about the Special Science Teleclass: Biology experiment :

Hi Aurora - question 20 isn't covered... did I miss it?

Answer:  Fast Ball

It's the seconds that are squared. Everything accelerates at 32 feet per second, per second. So it's velocity is increasing my 32 feet per second, each and every second. It's because acceleration is the change in velocity per unit time, just like velocity is the change in position per unit time (miles per hour, for example). For acceleration, the units are distance per time per time. I hope this helps!

Answer:  Special Science Teleclass: Astronomy

Sure! First, a star guide or something similar is an astronomer's best friend! You can read more about that here: http://www.sciencelearningspace.com/2014/11/whats-up-in-the-sky-2/ Next, get very comfortable with your telescope - inside, with the lights on! This will help you know exactly how to set it up quickly and accurately on a dark evening. Finally, I would recommend that you find a local astronomy club. They can provide hands-on help with your specific telescope and are a wealth of information about all things astronomical. I hope this helps!

Question: from Jen Shaffer about the Fast Ball experiment :

Hi Aurora! I am trying to understand the, "all things accelerate at 32 feet per second squared" part. What is being squared and why? Thanks!

Question: from Lisa Pearson about the Redox and single replacement reactions experiment :

How do we know which chemical was reduced and which was oxidized? Could we have the equations for these experiments?

Question: from Jessica Taylor about the Special Science Teleclass: Astronomy experiment :

Do you have any tips on finding things through a telescope?

Answer:  Science Teleclass: Light & Lasers & Holograms

I am not sure I understand your question.. what do you want to protect? Or did you mean "project"? If you mean "project", like projecting an image on the wall, it sounds like you are having trouble seeing the reflected image. Here are a couple of tips that may help: 1. make sure your room is dark, so the only light is coming from your phone 2. use images that have four sides (that's the kind of projector we are making) 3. move your head around until you can see the reflection - it may be lower or higher than you think Did that help? If not, re-watch the experiment part of the video again, or bring your expt to our live call next time so I can take a look, or if you can't wait that long, have someone snap a couple of pictures or video of you doing your experiment so I can take a peek and make suggestions.

Question: from Noelle Simpson about the Science Teleclass: Light & Lasers & Holograms experiment :

how does it protect my protector isn't working

Answer:  Special Science Teleclass: Chemistry & Chemical Engineering

Try logging out and then back in - did that fix it?

Question: from Eileen Wilder about the Special Science Teleclass: Chemistry & Chemical Engineering experiment :

hello its me harry again the video says i can not watch it

Answer:  Jan 2: Live Personal Call with Aurora!

You bet! Make sure to access the video call from the link on this page - it should be about a 30 min call. This is a chance for me to watch YOU and see what you've created and invented! And of course, you can ask any questions you want. It's easier for me to prepare for your questions if you ask them ahead of time... just email me before class!

Question: from Sam about the Jan 2: Live Personal Call with Aurora! experiment :

Hey Aurora - are we still doing a live call with you Tuesday?

Question: from Martha about the Pen & Paper Math Games experiment :

Wow... AWESOME Aurora!!! I LOVED this. I printed it out right away and my kids didn't even notice two hours flew by. And also guess what? They didn't even ask for more copies of this packet except the ship game. All they wanted was more paper, which I was so happy to give them. We now keep a notebook in the car just for playing these. And I love how they invented new rules and twists on these all by themselves! Yay for Supercharged Science!! And yay for Mom for getting a moment's peace without kids being plugged in!!

Answer:  Exponential Friction

Thanks for writing! I totally understand your thinking, and this science excerpt actually came from a college physics class I taught about friction and mechanics called the Euler-Eytelwein (or the Capstan) equation, which has the term "e" in it for exponential. You can read about it here. - it's used for calculating the friction of belts around pulleys, etc. Here's a more plain-English explanation of how it works. The Euler-Eytelwein equation relates the tension of two ends of a rope like this: T2 = T1 eμθ, where T2 is the tension in the rope due to the load, T1 is the tension you need to hold the load, μ is the coefficient of friction between the rope and the thing you're wrapping around, and θ is the angle made by all the rope windings (measured in radians, so one full winding is 2∏ radians). Hope this helps - and I appreciate your sharing feedback - sometimes I do make mistakes and it's important to correct those! Aurora

Question: from JL about the Exponential Friction experiment :

Aurora, I believe the increase in friction from aditional wraps around the pole is in fact less than linear, not exponential. The available normal force is not multiplied by wrapping, the coeffficient of friction is constant, only the area increases. In fact as friction reduces tension in the rope for successive wraps, normal force decreases. It is a very effective trick for anchoring or controlling a load, I use it often in rigging. But NOT "exponential", a mathematical term of specific meaning.

Answer:  Conversion Charts

Sure! I've added a link above for you.

Answer:  Inclined Plane

Aurora is a name that means "sunrise". It also is the scientific name for the effect when charged particles hit the poles of a planet (not just Earth), they cause a visible glow. You can see it here from space.

Answer:  Hydraulic Pneumatic Earth Mover

There's a package of the materials you need for this project in our Science Mastery program.

Answer:  Detecting the Electric Field

Sure - I bet you can figure something out! :)

Question: from Jen Shaffer about the Detecting the Magnetic Field experiment :


Question: from Sofia Grogan about the Conversion Charts experiment :

A conversion chart for Building Foundations of Scientific Understanding please. All levels.

Question: from Nohemi Pitts about the Detecting the Electric Field experiment :

Hi Aurora! We are just getting this project under hand. Can you make one with SUPER fun things like a volcano or something?

Question: from Tammie Earnest about the Hydraulic Pneumatic Earth Mover experiment :

on the video you talked about a "KIT" what is that?

Answer:  Osmosis in Potatoes & Beans

Yes, saltwater does help! You can also try adding vinegar to the saltwater for one batch versus adding baking soda to saltwater for another batch. Let us know which one of those you prefer!

Question: from Tammie Earnest about the Inclined Plane experiment :

I know this really doesn't have to do with the Chapter, but I was reading a book and it talked about the Aurora Boreilus or whatever (AKA) Northern Lights. That's your name, is that just a thing or something else?

Answer:  Seeing Electric Fields Using Your Spice Rack

Electrical fields aren't visible to us. We are able to "see" static electricity in a dark room - and on a larger scale, lightning - because the air is ionized and heated. So in those cases we are actually seeing the reaction and not the electrical force itself. I hope this helps!

Answer:  Carbon Dioxide and Photosynthesis

Great work and an interesting hypothesis! Plants definitely do release carbon dioxide during cellular respiration - mostly at night, but it can happen during the day as well. Please let us know how your further testing goes.

Answer:  How to Use a Microscope: Optics, Observing, and Drawing Techniques

Sure! There's a great explanation of oil immersion with some directions here: https://www.microscopeworld.com/t-using_microscope_immersion_oil.aspx

Answer:  Detecting the Magnetic Field

It sounds like the magnetic field is not very strong. Have you attempted to magnetize it a bit more? Be sure you're running the magnet along it in the same direction every time.

Question: from Lizanne Coetser about the Osmosis in Potatoes & Beans experiment :

We conclude that the potato in the salt water makes a far better and crispier chip than the potato in the fresh water. :)

Question: from Lizanne Coetser about the Carbon Dioxide and Photosynthesis experiment :

We also performed this experiment. We used a reasonable sized Thyme bush, large jar and a tea candle. We performed this multiple times and ensured a seal using Plasticine. On average the the candle stayed lit longer without the plant for about 10 sec . We Hypothesis that because we performed this experiment indoors, on a cloudy day in an area that was not well lit that in stead of releasing O2 the plant released CO2 instead. Because it was a Thyme plant with small leaves, the difference in the results were not significant. We will test our Hypothesis both indoors and outdoors, using the same and different plants and compare results.

Question: from Lizanne Coetser about the How to Use a Microscope: Optics, Observing, and Drawing Techniques experiment :

Hi Aurora, do you have instructions for the Oil immersion method? Cheers Lizanne

Question: from Tyler about the Seeing Electric Fields Using Your Spice Rack experiment :

why can't you see the electrical force in the cup pushing and pulling the dill? :)

Question: from Jen Shaffer about the Detecting the Magnetic Field experiment :

I also have one needle that is only attracted to other magnetized needles, but never repelled. Why is that?

Answer:  Detecting the Magnetic Field

Sometimes needles are hard to de-magnetize because they are so small and lightweight. If you are able to smack it a few times hard with a non0metal object (so it doesn't stick to it), you might have more luck. Rubbing the needle both ways will jumble up the domains inside as well.

Answer:  Monocots and Dicots

Wow - good catch! We recently had to redo all the images on the site and I will look to see if this one is in the wrong place. There were a few that were inserted incorrectly - thanks for your help in catching that!

Question: from Jen Shaffer about the Detecting the Magnetic Field experiment :

I tried dropping the needles to jumble up the iron atoms, but they still magnetized to each other. Also, why would rubbing the magnet on the needle in both directions not work? Thank you Aurora!

Question: from Michelle Morrison about the Monocots and Dicots experiment :

Dear Aurora, Our kids absolutely love the program (and so do us parents, we learn so much as well!) Just a question though, in the picture above you have what appears to be a Maidenhair Tree leaf which is a deciduous conifer. I understood that only flowering plants could be classified as dicots or monocots. As conifers are non-flowering is the leaf there as a trick question?

Question: from Tammie Earnest about the Unit 3: Matter (Solids) Answers to Exercises experiment :

I put the crystals from the Laundry Soap Crystal under a microscope, it was AAWWSSOOMMEE!!!!! ;)

Question: from Kaya sea Kimylongh about the Sensing Temperature experiment :


Answer:  Protozoa in the Grass

Just a small spoonful... it's not really that important. You don't even need to add it (this just makes sure you'll get something good to look at on your slide).

Question: from Jaymie Goitia about the Protozoa in the Grass experiment :

how much yeast do you put in the glass

Question: from Tammie Earnest about the Special Science Teleclass: Chemistry & Chemical Engineering experiment :

Thanks, but last night my older brother broke it into, like six pieces. OH, well. THANKS! :-)

Answer:  Plasma Grape

Ummm... yes, actually!

Answer:  Special Science Teleclass: Chemistry

Oh, no! We actually are changing it so that you have full access to all the units in the level you subscribe to. Originally we incremented the content because folks were upset that there was too much content, so we stepped it down and walked them through it... only now folks are upset because they don't have access to everything, so we switched it back. It was well-intended, but just didn't work for everyone! You should have access now, but if you still don't, I'll have Tonya follow up with you.

Answer:  Special Science Teleclass: Chemistry & Chemical Engineering

Oh, no! Sounds like something interesting happened, though... you now know how to make super-dry putty if you ever need it! Try making it again, and watch that 50/50 glue/water ratio. Try 40/60 and 60/40 to see if that helps make a difference. Sometimes glue sits around for awhile and separates and gets dehydrated so really mix that water in there.

Question: from Tammie Earnest about the Special Science Teleclass: Chemistry & Chemical Engineering experiment :

Daniel again, to clarify something that only happened once, i tried putting water over it but i don't think that helped! HELP!!!!!!!!!!!!! :(

Question: from Tammie Earnest about the Special Science Teleclass: Chemistry & Chemical Engineering experiment :

Aurora, my glow in the dark putty keeps breaking in piece when i toss it up then it hits the floor. How do I fix that? Daniel A. Earnest.

Question: from Daisy Toro about the Special Science Teleclass: Chemistry experiment :

I have been an e science member for a while now. But I still don't have access to a lot of the units and parts of the units. For example: I don't have access to any of these teleclasses. Is it possible to get access to these?

Question: from Daisy Toro about the Special Science Teleclass: Chemistry experiment :

Is it possible to have access to this teleclass?

Question: from Melissa Heath about the Plasma Grape experiment :

is the grape supposed to smoke? -Thomas

Answer:  Protozoa in the Grass

Not dangerous... just organic! :) IF it starts to smell, then you know you've got some good stuff in there to look at. Use gloves and tweezers to move your samples to the microscope slide and see what you've got!

Question: from Lizanne Coetser about the Protozoa in the Grass experiment :

Our culture has only been growing for 4 days and it stinks really bad!!! We live in a warm climate and it is summer now. Did we make something dangerous?

Question: from Tammie Earnest about the Special Science Teleclass: Chemistry & Chemical Engineering experiment :

loved the overflowing gooey stuff, that was so much fun. (I'm sure the Dinosaurs will love it) ;-)

Answer:  Membranes

I am not seeing the error on #4 - are you looking at the exercises for this section (http://www.sciencelearningspace.com/2011/05/cells-exercises/)? IF not, please let me know the url so I can take a look!

Answer:  Osmosis in Potatoes & Beans

Osmosis is the diffusion of water molecules through a membrane, where the water molecules move from high water concentration to areas of low water concentration. Salt starts osmosis by attracting water and causing the water to move toward and across the membrane. Remember that salt is a solute, and when water is added to a solute, it spreads out (diffuses) the concentration of salt, and that creates a chemical solution. Imagine the salt concentration inside a cell being the exact same as the salt concentration outside the cell - what would happen? Right - the water level will stay the same and nothing would happen. Now imagine there's more salt inside of a cell than outside it. What happens now? The water moves through the membrane into the cell causing it to swell with water. If the cell is placed in a higher concentration of salt (like sticking a carrot in a salt bath), the water will leave the cell, and that's why the plant cells shrink and wilt. This is also why salt kills plants, becaise it takes water from the cells. This doesn't just happen in plants, though. Animals can also get dehydrated if they drink ocean water. Water in cells moves toward the highest concentration of salt. I'll check the text reading to see if there's a typo.

Question: from Tamara Pyatt about the Membranes experiment :

Could you please correct the answer to exercise 4? thanks!

Question: from Tamara Pyatt about the Osmosis in Potatoes & Beans experiment :

The reading says that in osmosis the flow is from high concentration to low consentration but that is not what the potato experiment shows. the water goes from the potato to the high salt concentration in the cup. so is this truly osmosis and why doesnt the salt water go into the potato?

Answer:  Nature of a Sound Wave

I am sorry you're having trouble! I'm not able to find the link that isn't working. I'll have someone contact you so that we can sort this out ASAP.

Answer:  Special Science Teleclass: Chemistry

I'll have someone contact you right away to get this straightened out!

Question: from Stevei-Anne Matthews about the Nature of a Sound Wave experiment :

Hello. The AP Physics Workbook packet download link produces a 404 error page. Can this be resolved ASAP, please, so we can download it? Thank you. :-)
