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.

Answer:  Disappearing Foam Cup

Oops - sorry about that? I"ll have my team fix it right away.

Answer:  Disappearing Foam Cup

I apologize for the trouble. If you're going through the program by grade level, simply contact us with the grade level you need and we'll unlock everything you need for that level. We're working to get this resolved so you'll have access to everything you need, so in the meantime this is our "work around". I'll have Tonya bet in touch to make sure you have everything you need.

Question: from Klbelemjian about the Disappearing Foam Cup experiment :

This experiment is classified as 5th grade science, but I can't access it because the page says 9-12th grade. That's a tease. Please give access to K-8 members or remove it from 5th grade science category.

Question: from sjrecer about the Star Gazing experiment :

Song of the Sun experiment in Astronomy says Comments Closed. Can you please open the comments section there? Thanks.

Answer:  Scalars and Vectors

No, our curriculum is stand-alone. However many of our users are coming to us from another curriculum, like Apologia that they'd like to finish using since they've purchased it and want to complete it. So I created conversion charts for members that request them which you can find archived here: https://www.sciencelearningspace.com/2010/01/conversion-charts/ Since there were a lot of requests for Apologia specifically, I created entire pages that walk you through the program that best fits the Module you're working on. You can find them here: https://www.sciencelearningspace.com/grade-levels/advanced-projects-2/apologia-ap-chemistry/ https://www.sciencelearningspace.com/grade-levels/advanced-projects-2/apologia-chemistry/ https://www.sciencelearningspace.com/grade-levels/advanced-projects-2/apologia-advanced-physics/ https://www.sciencelearningspace.com/grade-levels/advanced-projects-2/apologia-physical-science/ https://www.sciencelearningspace.com/grade-levels/advanced-projects-2/apologia-biology/

Question: from Supercharged Science: a Homeschool Science Review | Nourishing Parenting about the Keeping a Scientific Journal experiment :

[…] my children to write more. Supercharged Science has a whole page that is dedicated to making a scientific journal in a professional […]

Question: from beth_goodwin about the Scalars and Vectors experiment :

Hi. I noticed you mentioned the Apologia Physical Science in conjunction with your Physics lessons. I think you said you were reworking some of their experiments. Is this meant to be a companion to your curriculum?

Answer:  How Does a Homeschool Student Get a Diploma?

We cover all the sciences, which ones did you focus on? Chemistry? Physics? Biology? Earth Science? Those are the four major ones for high school.

Question: from frauritsema about the How Does a Homeschool Student Get a Diploma? experiment :

What form of science do you list Supercharged Science is on a high school Transcript? I thought about just physics, but we have covered so much more? Any guidance?

Answer:  Science Teleclass: Light & Lasers & Holograms

Hi Aaron - were you doing the experiment with the pencil in the water? You can move around the glass to find where the pencil looks broken and when it doesn't. Were you able to do that part?

Question: from bac051201 about the Science Teleclass: Light & Lasers & Holograms experiment :

when I held the pencil straight up nothing happened why is this ----Aaron

Question: from robertdangelo about the Worms! experiment :

Thanks a bunch, Aurora. I'm actually doing a research report on the blue ringed octopus. You are a very good teacher and pretty easy to understand, so I thought that I would get the most info out of a possible octopus presentation that you did. Again thank you so much for your suggestion. ~ Andie D'

Answer:  Worms!

I actually don't but it certainly is something that is interesting, isnt' it? Here's further info on it for you: https://en.wikipedia.org/wiki/Blue-ringed_octopus https://www.youtube.com/watch?v=CeNTJhhsF9s https://oceanconservancy.org/blog/2017/03/13/the-blue-ringed-octopus-small-but-deadly/ I'm going to add this to the slide I show for Marine Biology when we talk about the most deadly fish in the sea!

Question: from robertdangelo about the Worms! experiment :

Thanks Aurora! By the way, even though this isn't related to worms, I was wondering if you have any videos on the blue ringed octopus. Thanks, Andie

Question: from lynn_mcaleece about the Answers to Respiratory & Excretory Systems Exercises experiment :

#15 is incorrect. Kidneys filter BLOOD and MAKE urine; they don't filter urine. https://www.niddk.nih.gov/health-information/kidney-disease/kidneys-how-they-work

Answer:  Newton's First Law of Motion

You're right - that is totally confusing! The "quarter mile" was additional information, not the answer! So sorry about that - I'll get that fixed. The answer is a lighter vehicle will will a short distance race, all other things being equal, because it has more resistance to getting moving.

Answer:  Worms!

That's a great question. There are 6 main kinds of soil: clay, peaty, silty, sandy, loam, and chalky. Clay and sandy are at opposite ends, the rest in the middle, and loam is the perfect type for plants. Clay is made of really small particles that compact really tightly together when it's dry, which means that it holds tightly onto its nutrients like calcium, potassium and magnesium but the texture isn't right to grow plants since it's hard for the roots to grow and slow to warm up in the springtime. You can tell if you have a lot of clay in your soil if you take a handful of damp soil, squish it in your hands for a moment and then open your hands. If the soil is still a ball and doesn't crumble, you have clay heavy soil. Worms will help your soil, but you have to attract them by first working your way through the spoil, breaking it up and mixing in compost (anything will work, and you cannot add too much!) and then also add gypsum to help push the clay particles apart. The worms will burrow through the clay to help aerate it and leave their castings behind, which will also help your soil. Hope this helps!

Question: from robertdangelo about the Worms! experiment :

Hi Aurora, it's Andie. The soil in my yard consists of mostly clay, and it's worms adapted to that environment. Will my worm column still work using the native worms and soil? Thanks, Andie D'

Question: from lynn_mcaleece about the Answers to Cardiovascular System Exercises experiment :

I think #14 is incorrect. ALL veins carry oxygen-poor blood back to the heart. The pulmonary ARTERY (not vein as you've indicated) is the only ARTERY that carries oxygen-poor blood. https://my.clevelandclinic.org/health/articles/17059-how-does-blood-flow-through-your-body

Question: from mad_tea_party about the Newton's First Law of Motion experiment :

Is the Answer page correct for Q. #3? It says, "like a quarter-mile," rather giving which one, either the lighter or the heavier.

Answer:  Introduction to Kinematics

You're right - the first two pages from this download are missing. I've re-uploaded it, so please check again. I notice there's not a lot of room between questions like there is for the rest of the HW sets, so I'll fix that soon, but I wanted to get this to you right away so you have it. There's a blank set without solutions first, and then the solutions are at the end. Does that help?

Answer:  Flashlight Laser Tag

I will make sure my team gets back to you right away!

Answer:  Underwater R.O.V. Project

I know - it's so sad! Here's a list of all the Radio Shack components we have listed on our website along with where you can find them now: https://www.sciencelearningspace.com/2016/08/radio-shack-component-replacements/

Question: from lgargiulo about the Gravity Go-Karts experiment :

suddenly physics is not cooperating, we've been doing physics for several months and now I suddenly am seeing that I don't have access.

Question: from nrobarge about the Introduction to Kinematics experiment :

Can you post a copy of the kinematics problem set without solutions? I am only seeing it with solutions, and it would be nice to have a blank copy to try on our own first. I did check, and the next chapter has it blank at the front and then has solutions at the end. Thanks!

Question: from karenhilligoss about the Flashlight Laser Tag experiment :

I am enrolled in the 9-12 grade but it says that I am only in the k-8 program. Help!

Question: from lynn_mcaleece about the What Happens to Food after You Put it in Your Mouth? experiment :

Please fixate typos in this section. There were a number of them again, which make the content more complicated than it needs to be.

Question: from catherine_pruitt about the Magnetic Tornadoes experiment :


Question: from catherine_pruitt about the Cosmic Ray Detector experiment :

Ok thanks

Answer:  Mechanical and Electromagnetic Waves

The idea with the example is that the device sticking out under the ship to detect the ship is completely surrounded by water. It's a really simple example for sound wave detection.

Answer:  Flashing Circuit

That's a great idea!

Answer:  Flying Paper Clip

You can find stronger magnets sometimes in unusual places, like latches and doors that pull themselves shut, in motors of toys, and other places. The ones in the video were about $2 from the store.

Answer:  Cosmic Ray Detector

Which part are you having trouble with? I can take a video and show it working - not sure why I didn't do that in the video! Sorry about that. You'll have the best luck with static electricity experiments on days that are warm and dry. If it's raining outside, it's not going to work (the water moisture in the air discharges any static build-up). The only other thing that can go wrong is that the mental rod you use is wrapped in insulation or the foil leaves are crimped together and not able to fly apart. Feel free to show me your setup ([email protected]) so I can see what's going on with your experiment so I can help!

Answer:  Eggshell Crystals

Yes you can use epsom salts, sugar, or table salt. You'll be making different types of crystals, but they all look about the same.

Answer:  Shopping List for Unit 7

Restaurant supply stores and some grocery stores also may sell it as well!

Answer:  Special Science Teleclass: Magnetism

Aww - thank you so much!

Answer:  Reading about Food and Digestive Systems

Thanks for letting us know - I am surprised there are so many as we had a professional editing company proof our material before publishing. Thank you for letting us know, and I did get the previous message and had it re-done as requested. I do apologize for the errors - I know how distracting it can be when language is not correct.

Question: from lynn_mcaleece about the Reading about Food and Digestive Systems experiment :

Please fix the many typographical errors on this page. I've submitted separate suggests via "Contact Us," suggesting that I notify you when I see typos, but I don't have time to point out the many on every page, nor should I have to do so when I am paying for this subscription. I would expect that you would have staff to do that job. That there are so many typos reduces the credibility of the information you are trying to present. It's very distracting.

Question: from apbaine about the Flying Paper Clip experiment :

My magnets were not strong enough. The paper clip did not as do in video.

Hmm, that does not sound right. It's a K-8 level experiment. I'll have my team take a look and correct any issues. Thanks for letting me know!

Answer:  Catapults

I think so - which part are you using it for?

Answer:  Bacteria Micromotor

Oh no! That's not right. We actually have a professional editing team that proofs everything for us. I'll have them take a look.

Question: from melissa_bachmann about the Bacteria Micromotor experiment :

There are several typos on this page "Since bacteria are made of only one cell, they are very cell." as one example. I recommend proof-reading this page.

Question: from lorannakitchen about the Catapults experiment :

would a chopstick work instead of a dowel?

Question: from apbaine about the Pendulums experiment :

It is like the frequency experiment.I will probably like this experiment. Signed-Apbaine

Question: from lorannakitchen about the Roller Coasters experiment :

this was fun!!!!! :) :) :)

Question: from Crabbyjean333 about the Classifying Objects experiment :

This was so much fun! We classified our buttons right down to the "species"! I definitely think it's a good beginning activity before introducing classifications because it gives the kids a hands on understanding of the concept.

Answer:  Monocots and Dicots

Sure! What did you want to know specifically?

Answer:  Soaking Up Rays

IF you have a strong light, like a car headlight that can work. Get your parents to help you as you position your experiment in front of the light and they can turn on (just the lights, not the car).

Question: from o_Asterix about the Monocots and Dicots experiment :

Are you going to add something about conifers?

Hi, Is there any alternative for sun light. Where I live it's very gray and we barley get any sunlight during winter because it's so rainy. Thanks- Sophia

Answer:  Acid Test

Can you take a video or send me an image? [email protected]

Answer:  Making Copper

You can use paper towels to catch the solid bits then throw them in the trash. The steel wool is just for additional clean up. You're making such a small amount that it's ok to discard.

Answer:  Plasma Grape

It takes a little patience to find that "sweet spot" in your microwave that will make this experiment work. You'll want to try changing the height as well as you hunt around for the right spot. Cherry tomatoes work well also - make sure there's a little skin still connecting the two halves!

Answer:  Hydraulic Pneumatic Earth Mover

Send it to me at [email protected] and I'll get it posted for you! (I am sur eyou can understand that we don't want folks just posting any pictures they want without having someone make sure it's ok first, due to the nature of our audience.)

Question: from cdylanrun about the Making Copper experiment :

What if we do not have steel wool? Can we use anything else?

Question: from maryannpalko about the Plasma Grape experiment :

I the experiment several times and it didn't work. No speak, no flame. I also tried a longer time, up to a minute.

Question: from o_Asterix about the Acid Test experiment :

Hi i tested a rock, but it somehow started to give out a color stain when i dried it i tried other liquids, but only vinigar made it stain

Question: from ksls185 about the Conversion Charts experiment :

Do you have a conversion chart for Elemental Science biology for the Grammar stage? TOC: http://d3r1z7wkgqhj9d.cloudfront.net/BGS%20sample.pdf Thanks!

Question: from robertdangelo about the Terraqua Column: How does water affect land and animals? experiment :

Hi Aurora, it's Andie. I have built three terraqua columns -- salt water, control and a calcium chloride one. I learned that calcium chloride is extremely dangerous for plants. When I told my father how much calcium chloride I put in the water, he told me it was too much (he double checked this with math). However, even though the plant inside the terraqua column should be dying, it is actually growing!! Also, a different weed and grass are both growing in the calcium chloride column. Please explain this. Thanks, Andie

Question: from kathmacgall about the Recent Astronomical Events experiment :

Wow! But how did they get the close up of the comet fragments when they were flying by in the beginning of the video? and why is Jupiter spinning so slowly while the comet fragment are going really fast?

Question: from bac051201 about the Quantum Mechanics: Double Slit Experiment experiment :

what would happen if there were 3 or 4 slits what if there were an immense amount how would it change

Question: from Aurora Lipper about the Terraqua Column: How does water affect land and animals? experiment :

Hi Andie! Anything that's dissolved in the water should be wicked up along with it. Give it a test run and see what happens :)

Question: from robertdangelo about the Terraqua Column: How does water affect land and animals? experiment :

Hi Aurora, it's Andie! I crafted two terraqua columns; the water in one of them being salt water. I have a question though -- will salt water travel up a wick AS salt water, or will the salt be left behind and only water goes through? Thanks, Andie

Question: from allisonbwillis about the Shopping List for Unit 1 experiment :

I have some small boat rocker switches from a eudax kit. Will these work for the hovercraft? Also, can I solder wires to 9V battery instead of purchasing the battery clip? How does RPM of motors in hovercraft project affect its success? Thanks!

Answer:  Steamboats

I think it was 3/8" ID.

Answer:  Recent Astronomical Events

That's a real video... cool isn't it?

Question: from jamallwh about the Steamboats experiment :

What is the diameter of the tubing in the video?

Question: from kathmacgall about the Recent Astronomical Events experiment :

Is the above video of jupiter real or computer graphic imaging? Was the video of the suns corona on an earth based telescope or on a satellite? If the telescope was earth based how we're they able to film the sun for several days strait with out the sun setting? And if it was on a satellite how did the satellite maintain a steady shot while it was flying through space? what was the name of the telescope/satellite?

Question: from bac051201 about the Basic Fundamentals experiment :

oops. i meant AA.

Question: from jamallwh about the Aurora's LEGO Robots experiment :

Do you remember how to download the firmware?

Answer:  Build and Fly a Real Alpha Rocket

Unfortunately, no - the rocket is something you have to purchase separately. Not everyone is able to launch rockets in their area, it's something you have to get special permission for.

Question: from Aurora Lipper about the Aurora's LEGO Robots experiment :

The command to upload is nqc -firmware firm0332.lgo from here: https://pbrick.info/rcx-firmware/ Does this help?

Question: from Aurora Lipper about the Drop Rocket with Launcher experiment :

It all depends on the launch angle! Give it a try and report your results :)
