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 Robert D'Angelo about the Special Science Teleclass: Electricity experiment :

Hi Aurora, it's Andie. On Tuesday, I found that my tri-stand LED was broken. One of its legs had broken off. How do I fix it?

Question: from Brook Batzel about the Rusty Balloon experiment :

after we do it can we take out the same type of salt as last and then eat it??!!

Answer:  Dimmers and Motor Speed Controllers

A little warm, yes... hot - no. :)

Question: from Candyce Ovadal about the Dimmers and Motor Speed Controllers experiment :

sorry i meant my potentiometer.

Question: from Candyce Ovadal about the Dimmers and Motor Speed Controllers experiment :

is it okay if my motor starts getting warm

Question: from Brook Batzel about the Bouncy Putty Slime experiment :

i made this with my mom once! and my brothers. and_#supecharged sience is cool!

Answer:  Salty Eggs

You have to use something that will start a crack in the shell, like ring on your finder or the side of the bowl. When the crack starts, then squeeze the egg carefully until it starts to split open with only one hand.

Question: from Michael Wills about the Salty Eggs experiment :

We can't find the secret to cracking an egg in one hand...

Question: from Susanne Gentry about the Circular Motion experiment :

This link is supposed to lead me to Apologia Physical Science exp. 14:1 "Sound waves travelling through a medium" but it is centripetal force instead.

Question: from Candyce Ovadal about the Bouncy Ball experiment :

ok thanks

Question: from Karen Daley about the Two Dimensional Motion experiment :

Thanks! It's all making more sense, now that we're working through the problems on the worksheets. We had fun with the easy popsicle stick launcher, too.

Answer:  Chemical Fingerprinting

I've sent you a private email.

Question: from Deb Swartzendruber about the Chemical Fingerprinting experiment :

Hi Aurora, Checking to see where we could purchase the goldenrod paper?! Thanks so much!

Answer:  Rusty Balloon

No, salt and sugar are two totally different molecules.

Answer:  Lava Lamp

Then it won't be colored! :) It will still work though.

Question: from Maricelli Pena about the Rusty Balloon experiment :

cool! but does sugar work

Question: from Maricelli Pena about the Lava Lamp experiment :

thats really cool !! but what if i don't put food dye

Answer:  Two Dimensional Motion

You can start the origin anywhere you want on the curve - in this example it's started where the ball is first released. Imagine being on a cliff (so that the ball can dip below the horizontal). Does that help? Yes, t = time elapsed. The half comes from when you derive the equation for acceleration from velocity (it's more advanced math than is covered here.. for now, just assume the half is there). When you add velocity or acceleration, they are both vectors, so you have to take into account which direction they are going in. It's not like adding apples together... you have to take into account which direction things are moving in. It's also the same with forces! If you have a friend pushing your right hand and another pulling your left, that's going to feel different than if they were both pulling you, right? That's why you have to take direction and quantity (amount of push, in this example) into account.

Answer:  Bouncy Ball

No, it will not work with isopropyl (totally different molecule).

Question: from Brook Batzel about the Taking the Salt out of the Ocean experiment :

salt comes out of the ocean thats what rain is seawater getting the salt takin out! thats a fun fact right?.

Question: from Candyce Ovadal about the Bouncy Ball experiment :

Can i use Isopropyl alcohol instead of ethyl alcohol?

Question: from Karen Daley about the Two Dimensional Motion experiment :

In the above equations, does t stand for time elapsed? Is the gravity subtracted because of the direction the vector is moving in? How does 1/2 affect the acceleration and the gravity in these equations? Why do we use 1/2? [Maybe the next lesson, on using trig with physics will help...?] Thank you!

Question: from Karen Daley about the Two Dimensional Motion experiment :

My student, Karis, wonders why the parabola starts where it does. Her first question upon seeing the parabolic path shown above was: Why does the projectile keep going down (below the x axis)? Can you help us understand what's presented here? Thank you!

Question: from Julia Raudenbush about the Planetary Magnetic Fields experiment :

Hi! Cool experiment. Can you please explain question and answer 4 in the exercises? Thanks!

Answer:  Chicken and the Clam

Good question! I would do an experiment to find out... and then let me know what you figure out! :)

Answer:  What is Energy?

I will have my team connect with you right away!

Question: from Lisa Croney about the Chicken and the Clam experiment :

If the incline were longer, would the clam chowder catch up to the chicken soup since it takes longer to accelerate, but accelerates to an overall faster speed since it has more inertia?

Question: from Ingrid Cordano about the Why bother with seat belts and helmets? experiment :

Mine also went backwards is that normal?

Question: from Ingrid Cordano about the Circular Motion experiment :

It's so cool!

Question: from Ingrid Cordano about the TaaDaaaaa!!! experiment :

I love it!

Question: from Ingrid Cordano about the Building Bridges experiment :

Can other paper besides index cards work?

Question: from Julia Raudenbush about the Eclipses and Transits experiment :

Hi! These demo experiments are interesting, but we aren't sure where to find the answers to the questions without looking at the answer sheet, which defeats the purpose. Please advise, thanks!

Question: from Patti Heilmann about the Lava Lamp experiment :

cool awesome

Question: from Andria E. ColemOn-Harville about the What is Energy? experiment :

I have asked for access to this unit for my high schoolers. I was told I have access, but I still can't get in.

the pi guy

Question: from Brook Batzel about the Bouncy Putty Slime experiment :

PUB PUB PUB PUB!

Answer:  Date Shift Cipher

Whoa - you are so right! The answers I get are these: 9. GLBZC GNHNQ 10. MLFZT GAATO GRMZQ Does it match what you get also? So sorry about that - I will get the new ones published right away! Aurora

Question: from Michelle about the Date Shift Cipher experiment :

We enjoyed the video on the Date Shift Cipher and printed out the worksheet to work some more problems. We are having difficulty with numbers 9 and 10 however. The cipher does not seem to work. This is what we get and it does not match your answer key. Any suggestions? #9 - GNATTEOZT #10 - MDETMEASSIXPOSP

Answer:  Flashing Circuit

The type of LED you have will have a different amount of resistance, and by moving where that resistance is in the circuit will have a different effect on ho wit works. Basically, all LEDs are not the same... so you have to be creative and flexible in your electronics design. Does that help?

Answer:  Rubber Eggs

You don't, actually! The shell has gone through a chemical change, and it's no longer brittle, so it stretches instead of fractures when you put pressure on it.

Answer:  Celebrate National Engineers Week: Feb. 18-24, 2018

Try logging in again... the video is working over here.

Answer:  Pi Day is March 14

Who is whom?

Question: from Melody Konkel about the Pi Day is March 14 experiment :

who is he

Question: from Tammy Yoshimoto about the Celebrate National Engineers Week: Feb. 18-24, 2018 experiment :

sorry but the video does not work

Question: from Maricelli Pena about the Salty Eggs experiment :

Thats so cool ! but what would it do if I put 10 scoops of salt and just 1 a scoop of water

Question: from Maricelli Pena about the Rubber Eggs experiment :

how can you brake it!

Question: from Evangeline Gregory about the Flashing Circuit experiment :

at one point in the video`you said if the LED didnt light up, move the resistor to the positive side of the breadboard. I did, and it worked, but i dont understand why.

Question: from Brook Batzel about the Cool Milk Trick experiment :

#this type of art is better then me!

Question: from Brook Batzel about the Cool Milk Trick experiment :

im a pretty good artist im not nearly good as one of my friend's art neither as good as this type of art!

Question: from Brook Batzel about the Cool Milk Trick experiment :

i've only done the waterscope ill have to do this on saturday LOL!

Answer:  The Best Parent-Annoyer Ever

Try making a cone out of a sheet of paper maybe?

Answer:  Electroplating

You can find copper sulfate here: https://www.homesciencetools.com/copper-ii-cupric-sulfate-30-g

Question: from Maricelli Pena about the Moon Sand experiment :

thats so cool !!! cool and fun !

cooooooollllllllllllllllllll!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Question: from Melanie Church about the The Best Parent-Annoyer Ever experiment :

What if you don't have that kind of cup or a paper cup? What else can you use? Thank you

Question: from Madlen Penn about the Seeing Sound Waves using Light experiment :

I do this experiment in a much more simplified way... Granted, no cool lasers are involved in my version, but it gets the job done! :) I make my drum (can + balloon), set it on the table, and place 4-5 rice kernels on it. The rice picks up the vibrations readily! We have made the kernels dance like crazy using everything, from our best singing voices, to the most ridiculous noise-makers.

Question: from Robert D'Angelo about the Homeschooling Help Websites experiment :

Aurora, I just want to get this off my chest . . . My nine-year-old daughter ("Andie") has been using your program for about a year now (you may remember some of the notes she has sent you, which you promptly answered). Your program has proved to be everything you claimed it would be and more. My daughter is turning into quite the young scientist. She is learning the discipline it takes to do true and accurate research. Your enthusiasm has been contagious, and she has caught it. I watch with pride as she goes through the lessons, keeping her journal and carefully recording and analyzing her data. The decision to homeschool was the hardest decision I have ever made. I still have nightmares. But, I am absolutely confident that your program is the best investment in my daughter's education that I could have made. At least I know that her science education is in the best of hands . . . yours. I just don't know how to thank you. Words just fail me . . . Cheers, Bobby D'

Question: from Melody Konkel about the Celebrate National Engineers Week: Feb. 18-24, 2018 experiment :

Cool ! :)

Answer:  Hidden Carbon Dioxide

Yes, along with nitrogen and oxygen. Not all the oxygen is converted to CO2 with every breath (that's why people breathe into a paper bag when they hyperventilate don't suffocate initially).

Question: from Brook Batzel about the Hidden Carbon Dioxide experiment :

dont we breath out carbon dioxide?

Answer:  Hidden Carbon Dioxide

Yes, about 20% of the air you inhale is oxygen and about 4-5% of that oxygen gets converted to CO2 with every exhale

Answer:  Birds and Mammals Exercises

Here's an interesting article about it: https://www.ltsmiles.com/a-quick-look-at-the-animals-with-the-most-teeth/

Question: from Nicole Landers about the Birds and Mammals Exercises experiment :

What is the number of maximum teeth an animal could have?

Question: from Brook Batzel about the Hidden Carbon Dioxide experiment :

We exhale carbon dioxide! isn't that right? EVERYBODY does!

Answer:  Chemical Fingerprinting

No not easily, but you can do a similar experiment using cobalt. Look at "Cobalt Colors" experiment!

Question: from Andrea Albury about the Chemical Fingerprinting experiment :

Can you make goldenrod paper?

Answer:  Special Science Teleclass: Electricity

Hi Andie! Can you send me a picture of the front and back of the buzzer? You can send it to my email here: aurora@superchargedscience.com If you have a short video you can send that also so I can help!

Question: from Robert D'Angelo about the Special Science Teleclass: Electricity experiment :

Hi Aurora, it's Andie. In the teleclass video, your buzzer has wires but mine has snaps. I'm not sure how to hook it all up together! Can you help me?

Answer:  Special Science Teleclass: Electricity

It might, depending on the alarm's voltage requirements - try it and see if you can get it to work!

Question: from Nicole Moore about the Detecting the Magnetic Field experiment :

sooo much fun.... the best part is it accualy works. such a good idea fo a campout in the woods

Question: from Robert D'Angelo about the Special Science Teleclass: Electricity experiment :

Hi Aurora, it's Andie. I have an electronic snap circut kit and I am using the alarm snap circut from it. Will this work?

Answer:  Robotic Hand

No - you can use any color you like!

Question: from Laura Walters about the Disappearing Frog Experiment experiment :

This is really cool, I found it really quick

Question: from Laura Walters about the Robotic Hand experiment :

do you need colored straws? thx:)

Question: from Brook Batzel about the Rubber Eggs experiment :

there are two ways the vidio and getting rubber and shaping it like an egg.

Answer:  Non-Messy Squishy Slime

That's a really good question - I am not sure! I tried looking it up in my chemical reference book, but it didn't have anything useful in it.

Answer:  Rubber Eggs

Cooked definitely. We want to be sure there isn't any chance of bacteria getting you sick!

Question: from jerezkids about the Rubber Eggs experiment :

Should the bones be cooked or uncooked chicken wings?

Question: from Lizanne Coetser about the Non-Messy Squishy Slime experiment :

Hi Aurora, what would the formula look like for Psyllium and water to form the slime? Tx

Answer:  Foam Pumice

It's an exothermic reaction, which means that when the reaction takes place, it releases energy (gets hot) when it forms the new molecules.

Question: from Robert D'Angelo about the Foam Pumice experiment :

Hi Aurora, it's Andie. Why does the reaction get so hot?

Question: from Melody Konkel about the Turning Water into Wine experiment :

ok thanks aurora :)

Answer:  Rock Workshop

The streak you are seeing left behind is a tiny bit of crushed up powder trail of the mineral you are streaking across the plate. The streak plate is usually harder than most minerals, so that's why it works. If you test a mineral harder than the streak plate, you'll get part of the streak plate turning into powder on the mineral.

Question: from Robert D'Angelo about the Rock Workshop experiment :

Hi Aurora, it's Andie. When I was testing shale for a streak test, on my black and white streak plates I found a cream colored streak on the black one and a grey streak on the white one. Why is this happening?

Answer:  Barrel Roof

Thanks for the tip! If you send me an email (mailto:aurora@superchargedscience.com) with the image attached, I can add it to your post! Aurora

Question: from Tonya Thomas about the Butterfly Life Cycle experiment :

cooool

Question: from Tonya Thomas about the Predator-Prey: Who Eats Whom? experiment :

so cool

Question: from Dina Zervoulakos about the $1 Word Search experiment :

The word gymnastics costs $1.30

Question: from Jen Cote about the Barrel Roof experiment :

We gave up on this one last year, even with our years of intricate origami, it wasn't working. Just tried it again. Instead of following the video's advice to face lines toward table, we kept them face up where we could see them and folded the valley folds up against a ruler. (Be sure to hold ruler firmly for entire length of fold or line will swerve.) And we creased every fold with edge of the ruler. This solved our problems--lines now end up spaced exactly enough that the folding step finally works! YAY! It held 561 pages or 3040 grams!!! Hope what helped us helps someone else! now if we could just figure out why there is no way to add a photo to this-not from our mac nor our iPad... :( anyone have solved that problem? :)

Question: from Melody Konkel about the Meteorites experiment :

ok thanks aurora :) :)

Question: from Melody Konkel about the Educational Games That Teach experiment :

thanks aurora :)

Answer:  A Weighty Issue

It does seem odd, doesn't it? It's SHAPE, not density that matters with things falling. A golf ball and a ping pong ball are the same size and shape, and they hit the ground at the same time. But they are different weights (the golf ball is more dense it has more mass for its size). It's because we live in an ocean of air called an atmosphere, and those air molecules need to be pushed out of the way to make way for the object falling through it. That's why shape matters, not weight.
