Answer:  Measuring a Molecule

Can you send me a snapshot of what you have so far? I am at aurora@superchargedscience.com

Answer:  Gyro Wheel

It's funny you mention this, because I've looked for a replacement (it's about 20 years old) and haven't found one! I was thinking I could make one out of a rubbery-gel substance, but am not sure which I will try first.

Answer:  Chemistry review

Hi Katie, You should have access to both, as the content is not available for purchase by topic, only by level (either K-8 or 9-12). Does that help? Aurora

Question: from Tania Harris about the The Old Switcheroo experiment :

I'm the son of Tania Harris, Nathan. I love the way supercharged science is, and I've been doing it for about 2 months now! And I can't wait to do more! Thanks, Nathan

Question: from Lisa Pearson about the Measuring a Molecule experiment :

We are having trouble with the problems at the end of this lab. Could you explain how you got your answer? I've used the formulas given in the lab and am not coming up with anything close.

Question: from Christine King about the Gyro Wheel experiment :

You showed a gyroscope with a gel center that stretched. What was it called, and where could I get one? My grandson thought that was pretty cool.

Question: from Katie Renick about the Chemistry review experiment :

I recently purchased physics and have decided to change to chemistry. How do I go about doing that? Thank you, Katie

Answer:  More Hints on Solving Physics Problems

Yes, they are included for reference. You can recopy the questions or cover the answers to work the problems yourself.

Question: from Georgia Oberg about the More Hints on Solving Physics Problems experiment :

So, are the answers supposed to be written in already on the practice problems set above?

Answer:  Detecting the Magnetic Field

The compass is reacting to the magnet because it's so close to it. The compass itself is magnetic. Normally the needle would simply line up north and south in alignment with the Earth's North and South Poles. However, getting the magnet so close to the compass means that it has a bit stronger of a magnetic pull than the Earth due to its proximity. So you see the reaction - the compass doesn't quite know where to point while it tries to align with the nearby magnetic field that is in constant motion.

Question: from Tammie Earnest about the Detecting the Magnetic Field experiment :

why was the compass going crazy when you were rubbing the needle? Daniel A. Earnest

Answer:  Shopping List for Unit 17

What kind of problem did you have with this list? Is there something missing, or incorrect?

Question: from Lizanne Coetser about the Shopping List for Unit 17 experiment :

I had problems with the shopping list too. Cheers

Question: from Erin Gemmen about the Is It Alive? experiment :

that was good

Question: from Melanie Williamson about the Easy and Spooky Halloween Projects experiment :

Thanks!!!!

Question: from Robert D'Angelo about the Carbon Dioxide experiment :

Hey Aurora, it's Andie. When I did experiment 31 for Chem C3000, my dad and I added 3x as much sodium hydrogen sulfate to the test tube without the limewater as you said to put in. When we were finished with the experiment, we noticed that on the bottom of the test tube there was two cm worth of solids. A few minutes later when we looked in the test tube, all of that solid had dissolved. Why did this happen?

Answer:  Mussel Dissection

Thanks Julia - and you're right! These videos are used with permission from the author, but they are not a good quality or thorough in the sense of providing a lesson. We are working on shooting a new set of videos that will cover all of these things and make it clear and easy to do dissections, after we've completed our current set of projects.

Question: from Julia Raudenbush about the Mussel Dissection experiment :

Yvonne I found this link. http://www.biologyjunction.com/clam_dissection.htm that was helpful. The starfish from home science tools came with the guide, but the mussel did not. Not sure why. These dissection labs are enough to get you started, but definitely not complete lessons. Diagrams would be helpful. The quality of this video is very poor, and difficult to locate organs on our mussels based on the video.

Answer:  Cool Blue Light Chemiluminescence Experiment

I would recommend this for students interested in chemistry and have an adult handy to help them with the chemicals. Make sure you read over the instructions carefully and watch the video so you're able to perform the experiments safely (so you can go on to do more science in the future!)

Question: from Kelli Kruid about the Cool Blue Light Chemiluminescence Experiment experiment :

Would you only recommend doing this with older students ????

Question: from Kelli Kruid about the Cool Blue Light Chemiluminescence Experiment experiment :

That is so cool !!!!!

Answer:  Easy and Spooky Halloween Projects

I had a hand held fog machine (I am sure you can find these on places like Amazon.com) that I attached a flexible clear tube to the end of, and then since I have so much hair, it was easy to hide the tube on my head. If you poke holes along the tube length, then smoke comes out all over!

Question: from Eileen Wilder about the Pop Rockets experiment :

thanks a lot i will ask my mom to buy one or i can buy one with my money

Question: from Melanie Williamson about the Easy and Spooky Halloween Projects experiment :

That was from me, Gabe sorry I forgot to say that.

Question: from Melanie Williamson about the Easy and Spooky Halloween Projects experiment :

How did you get your hair to smoke, If I want to make something look hazy/smokey for Halloween?

Answer:  Pop Rockets

Hi, Harry! You can get Alka Seltzer tablets from the grocery store or pharmacy. You can probably find M&M tubes there as well. They look like this.

Answer:  Cool Blue Light Chemiluminescence Experiment

Good question! There is actually a variation of this experiment where bleach is substituted for the hydrogen peroxide. In this variation, the reaction takes place much faster and the light is even brighter!

Question: from Eileen Wilder about the Pop Rockets experiment :

:)

Question: from Eileen Wilder about the Pop Rockets experiment :

oh and my name is harry! ;)

Question: from Eileen Wilder about the Pop Rockets experiment :

umm... were do you get all of this stuff to make it?

Question: from Kelli Kruid about the Cool Blue Light Chemiluminescence Experiment experiment :

Hey Aurora I was just wondering what would happen if you added one drop of pure bleach into the light solution.

Answer:  Taking the Salt out of the Ocean

I'll have my team connect with you right away!

Answer:  Mixing Cold Light

You can find disposable test tubes here: https://www.homesciencetools.com/test-tubes-polystyrene-13x100-mm-12-pack

Question: from Cindy Soderlund about the Mixing Cold Light experiment :

Hi. Where can I buy disposable test tubes?

Question: from Cindy Soderlund about the Taking the Salt out of the Ocean experiment :

I'm confused as to why I don't have access for this experiment. I have access to the other experiments before this one in this unit. I'm logged in, too. Help!

Answer:  Zinc Dust

The flame should be turning blue and that would indicate that the zinc is undergoing a chemical change to zinc oxide. If this didn't happen, I suspect that your additional variables (wind and possibly sunlight?) could be impacting the experiment, resulting in the zinc not getting oxidized. The other issue could be impure zinc samples. My recommendation would be to try again if you're able, while controlling for wind and sun as much as possible. If the flame is blue, you should see the change to yellow and back to while once it cools. Let us know how it goes!

Question: from Lisa Pearson about the Zinc Dust experiment :

We used the wick-less alcohol burner with denatured alcohol for fuel, the flame looked normal. We were outside, with a slight wind, so maybe the temp of the flame varied. Three different samples of zinc dust. Each sample turned a different color- one purple, one yellow/green, one black.

Answer:  Can Fish Drown?

Home Science Tools is an excellent resource for most Chemistry supplies (and many other topics as well!) You can easily make a bend in a 5mm glass tube by heating the tube in a candle or alcohol burner flame until the glass softens. Then carefully bend the tube to the desired shape and hold it in that position for a few seconds until the glass hardens again. Be sure to heat the glass tube over a section about 1‐1/2′ long to avoid crimping the tube when you bend it. I hope this helps!

Question: from Cindy Soderlund about the Can Fish Drown? experiment :

Hi. Where can I buy a test tube clamp and right-angle glass tube inserted into a single-hole stopper?

Answer:  Zinc Dust

Do you mean that the zinc itself turned purple, then yellow/green, then black? What color was the flame? It sounds like there are other variables impacting the results. The spoon is a metal alloy, but it should be fairly stable.

Answer:  Constant Acceleration

Thanks for the update!

Question: from Kimberly Voelkel about the Constant Acceleration experiment :

We found the solutions to our question "A dog begins running and accelerates..."! Sorry about the confusion.....we got it now! :)

Question: from Lisa Pearson about the Zinc Dust experiment :

We tried this three different times today. The first time, the zinc turned purple; second time the zinc was yellowish while hot and green when cool; third time the zinc turned black. Any ideas why? All the samples were from the same, newly opened bottle, same location, same alcohol burner, same spoon. The spoon was stainless steel.

Answer:  Pinhole Camera

Yes parchment is too thick. Tracing allows some light through. You can get it at art or office supply stores, usually by the sheet or a small pad. If you have very thin paper that would work also.

Question: from Tammy Halladay about the Pinhole Camera experiment :

we tried and used parchment paper but i think it was to thick what exactly is tracing paper?

Answer:  Underwater Presidents

What a great question! Surface tension is basically the "film" created where a liquid and a gas meet. This film is impacted by different things, depending on both the liquid and the gas in question. We know that surface tension is changed by many factors, including oxidization, pressure, temperature, impurities, and various chemicals. Normally oxygen by itself would decrease surface tension, but the bubbles of carbon dioxide formed by carbonation create pressure, which does increase the surface tension

Answer:  Constant Acceleration

Oh gosh, you're right - these are missing! I'll get these fixed and post the updated file right away.

Question: from Jeanette Spence about the Underwater Presidents experiment :

We did this experiment with different kinds of liquids: testing the number of drops that the penny would hold of each water, grape juice, soapy water and sparkling smart water. My daugther's data didn't allow us to clearly come to any conclusions about the soapy water and the juice. Perhaps there were less drops with these two liquids. However it did look like the penny held more carbonated smart water. Does carbonation increase the surface tension of water and why? I can't find anything online about this or at least anything that I can understand. Thanks for your help.

Answer:  Watch Your Weight

Thanks for catching that! I'll have Crystal email them to you and we will get the file updated.

Question: from jerezkids about the Watch Your Weight experiment :

There are no answers to questions 1 - 3 of the download handout. It just repeats the question but no answers. Thanks

Question: from Kimberly Voelkel about the Constant Acceleration experiment :

We have printed out the chapter 1 kinematics lesson. We did the driveway races and are answering questions provided with the lab. Is there an example page we could see to make sure we are doing this work properly? Also, there are acceleration problems included ..."a dog begins running and accelerates at 2.5 m/s...." Where are the answers to these problems? Thank you for your help. We are learning and definitely need it. :)

Answer:  Newton's First Law of Motion

I'll have someone contact you to help!

Oops, thanks for checking! It's available here: http://www.sciencelearningspace.com/2017/06/alkali-metals-here/

Answer:  Sundial

Sure! You can use any straight edge that's long enough.

Question: from Melanie Church about the Sundial experiment :

Hello.Can you use something else other than a ruler to make the sundial straight? Thank you.

Question: from Jennifer Price about the Converting Units experiment :

Once you multiply 12x12, don't you lose the squared notation? Because 12 squared is 144.

Question: from Tania Harris about the Special Science Teleclass: Flying Machines experiment :

cool

Question: from Julie Daw about the Periodic Table experiment :

Where should I look for the video mentioned at the end of this wonderful lesson about the periodic table? I think the video is about the first column of metals interacting with water.

Answer:  Getting Air from Water

I am not sure where you'd find one locally, but you can easily make a bend in a 5mm glass tube by heating the tube in a candle or alcohol burner flame until the glass softens. Then carefully bend the tube to the desired shape and hold it in that position for a few seconds until the glass hardens again. Be sure to heat the glass tube over a section about 1‐1/2' long to avoid crimping the tube when you bend it. I hope this helps!

Answer:  Seasons

Liquid crystal sheets are what thermometer strips for aquariums are made from. You can also find them on Amazon.

Question: from Eileen Wilder about the Eclipses and Transits experiment :

thats relly cool

Question: from Michelle Adkins about the Getting Air from Water experiment :

Do you have any suggestions as to what kind of store carries the 90 degree bent glass tubing? I see the tubing online (but only at a couple of science store websites), and I was going to try to find it locally.

Question: from Cindy Soderlund about the Seasons experiment :

Specifically, what is it called at the fish tank store and it's purpose for fish because the sales rep has no clue of what I'm looking for when I say liquid crystal sheet?

Question: from Gina Gazelka about the Mohs’ Hardness experiment :

Max: and aggate has a mohs scale of 6-7 i belive.

Answer:  Unit 1: Mechanics (Force) Video

Interesting theory! You are correct that like forces repel. In physics, kinematics is simply a description of motion and the dynamics would be the reason that the motion happens. Electricity is a force and is certainly a dynamic force. However, in this case the dynamics would be as a result of positive force (or work) applied by you in pushing the box. The negative work would be done by the friction of the box as it moves across the surface. I hope this helps!

Answer:  3 Polarizer Experiment

You need to be logged in first.

Answer:  Acceleration

It's just the magnitude (the amount of the acceleration) without the direction information included. For velocity (because it's easier to visualize): instead of 10 feet per second heading west for example, it would be just 10 feet per second.

Question: from Jennifer Price about the Acceleration experiment :

How can something be accelerating as a scalar without a direction?

Question: from Olivia Vail about the 3 Polarizer Experiment experiment :

how do you watch the experiment videos?

Question: from Ginger Regan about the Unit 1: Mechanics (Force) Video experiment :

Hi. I am wondering if positive and negative charges are the reason that kinematic forces happen? That is, if I push a box, do the electrons/protons in my arms and hands create a voltage difference between me and the box when I touch it, causing the box to "want" to move away from my hands?

Answer:  Bubble Experiments

The answers to this should be in the video - I'll check it over again and post anything that is missing.

Answer:  Measuring the Speed of Light with a Chocolate Bar

That's still fantastically close given that we're using a chocolate bar and a microwave of various accuracy! You can try doing this experiment 3 times and average the final results to give an overall answer, which may be closer.

Answer:  Force-full Cereal

Because of the iron inside! Did you read through the text below the video?

Answer:  Burning Sulfur

You need to purchase denatured alcohol because it's hazardous to ship, and the test tubes are in the box in the foam packaging. The O2 you create during the experiments. Enjoy!

Answer:  Balancing Chemical Equations

Thanks for catching this! I am still uploading all the videos for this section of the program, and appreciate your eagle eye! This one had the wrong video on the page, which I fixed now.

Answer:  Science Teleclass: Light & Lasers & Holograms

Its in the worksheet download right under the video!

Question: from Heather about the Barometer experiment :

What does it mean when the stick goes up? Does it mean there isn't a storm coming? Thanks, Noah

Answer:  Can Water Be Heated With Composting Plant Material?

I found one here online: https://www.amazon.com/gp/product/B0000CF5MT/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Answer:  Kinematic Equations Example Problems

Yes, that's the same thing, just stated slightly differently :)

Question: from Cathy Clifton about the Force-full Cereal experiment :

Why do they connect together?

Question: from Kathleen Broaddus about the Burning Sulfur experiment :

We just broke into our chemistry 3000 box and wondered where we can find the denatured alcohol and the O2 test tube that's needed to light the burner and do this experiment?

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

Can you provide the template for the plastic cut out to do the jelly fish (on cell phone) experiment? and also what is the site for the jelly fish? Thank you. Belle Brunner
