Question: from Olwen watkins Olwen watkins about the Microscopes and Telescopes experiment :

thanks

Question: from David Harn about the Microwaving Soap experiment :

We didn't have any Dove soap around, so we tried it with Irish Spring. It doesn't come out near as "fluffy", but it works, although it produces a less than desirable aroma. (Could be the perfume or the dye. I'm not sure which.) My eight year old daughter complained that she couldn't see the action through the shielding in the door glass, and it was rather hard for me to see, as well, but the result was clearly in line with what we expected. We'll get a bar of Dove and see if the results are more to her liking. (More fluffy and less bad smell.) Thanks for the great experiments. My kids are in love with the program and every project we've done so far.

Question: from David Harn about the Significant Digits experiment :

I have yet to figure out where this will be helpful, but all knowledge is welcome. Both I and my children (age 8 and 10) are hooked on learning anything and everything there is to learn. I'm sure this information will come in handy in our further explorations of science. Thank you.

Question: from Indu Patel about the Hovercraft Spaceship experiment :

Hi! This is Sindur. I am having the same issue for only this video. I can not see the video screen on the page, and this is the only video that does this. I am also experiencing sound issues for a few specific videos. I have tried to reload the page, but nothing seems to be working. Do you have a way to fix this? Thanks!

Question: from Shawna Johnson about the Gravity Powered Go-Kart experiment :

Would love to have access to this!! I paid for it, but can't seem to access anything other than the shopping list.

Question: from Kimberly Voelkel about the Hot Liquids and Cool Solids experiment :

Please ignore my posted question.

Question: from Kimberly Voelkel about the Hot Liquids and Cool Solids experiment :

Are there any substitutes for washing soda, ice melt or Dri-EZ?

Question: from Kimberly Voelkel about the Hygrometer experiment :

Are there any sustitutes for hair?

Answer:  Corny Slime

There really isn't any other substitute... you have to use a speaker for this particular experiment.

Question: from Lisa Pearson about the Stirling Engine experiment :

Cool it looks awesome!!!!

Question: from Kimberly Voelkel about the Corny Slime experiment :

What can I use instead of an OLD speaker and a bass?

Answer:  Cartesian Diver

Not really, because the cap needs to be screwed on tightly (so it won't pop off when you squeeze the sides) and you also need the container to be clear so you can see through it.

Answer:  Shopping List for Unit 4

Yes it's included with the Science Mastery program kits we sell on our website.

Question: from Olwen watkins Olwen watkins about the What is Fire? experiment :

soooooooooooo cccccooooooll

Question: from Renata Rosenfeld about the Shopping List for Unit 4 experiment :

Is there a full kit for the earth mover? I couldn't find it.

Question: from Jami Bustamante about the Cartesian Diver experiment :

Would a plastic milk container work in place of a 2 liter bottle?

Answer:  Squished Soda Can

Make sure you are logged in first!

Answer:  What is Fire?

Until the alcohol is completely consumed and the fire dies out (due to lack of fuel). Usually about 5 seconds.

Answer:  Flying Contraptions

That's an interesting idea... you can try, and then let me know what happens!

Answer:  Ten Static Electricity Experiments to Mystify Your Kids

This is one of the very few experiments that didn't have a video, however in a couple of weeks I am releasing a new experiment just in static electricity (with a video) that will have a lot of cool ideas for you to try. Check the Summer e-Camp Electric Lab soon!

Question: from Kimberly Voelkel about the Ten Static Electricity Experiments to Mystify Your Kids experiment :

I can't find the video. Can you make that video appear?

Question: from Kimberly Voelkel about the Squished Soda Can experiment :

I can't watch the video because it did not appear. How am I going to make that video appear?

Are you supposed to put a 3rd circle in the middle?

Question: from Olwen watkins Olwen watkins about the Hybrid Rockets experiment :

sooooooooooooo cool

Question: from Melanie Williamson about the Diamond Kite experiment :

okay, thanks!

Question: from Melanie Williamson about the Special Science Teleclass: Thermodynamics experiment :

whoa, it is so weird to think nothing you touch is really cold or hot,(well it's just what we call both kinds of heat flow ) . it just is sensors in your skin that read heat flow. Thanks Aurora I learned a lot.-Gabe

Answer:  Chicken and the Clam

Not a problem at all... the ice stays because it's surrounded by a fluid and not rigidly locked into place like solid object would be. Ice has more inertia (resistance to motion) than the water around it, so the water moves more easily than the ice. Great question!

Question: from Andrea Rosario about the Chicken and the Clam experiment :

Hi Aurora! What you said about the chicken broth staying in place while the can moves got me thinking.... when you get a glass of ice water and you move the cup clockwise and counter-clockwise, the ice stays in the same place and position most of the time. Why does this happen? Sorry if it's a little off-subject. Arteah Rosario

Question: from Ingrid Cordano about the Pendulums experiment :

:)

Answer:  Reading about Intermedate Level Chemistry

I am guessing you are referring to the USC DVDs that are Chemistry 1 & 2 from this page: http://www.superchargedscience.com/usc-info.htm If so, then no, those are only intended for K-8. I began working on Chemistry 3 which would be just for High Schoolers, but then I ran into a problem... there was so much content for this course that it ended up needing over 30 DVDs to fit everything, even at low-resolution! So what I've done now is put it together and organized it into a HS Chemistry course in the e-Science program online, which you can find here: http://www.sciencelearningspace.com/grade-levels/advanced-projects-2/adv-chemistry-course/ Please note that I am still creating and publishing this course, so you'll see updates and changes posted over the next couple of months. Hope this helps!

Answer:  Quick 'n Easy Slingshot Rockets

What if you turn up the end of the paper clip to make kind of a stop there? You may have to use pliers...

Question: from Erin Allport about the Reading about Intermedate Level Chemistry experiment :

Are the chemistry 1 and chemistry 2 classes enough for a high schooler who wants to pursue an English degree in college?

Question: from Amanda Mcabee about the Quick 'n Easy Slingshot Rockets experiment :

the rubber band won,t stay on the hook.

Answer:  How to use a Digital MultiMeter

It depends on how salty your water is. If It might be interesting to see how electrical resistance (make sure you are measuring ohms here) changes as you add more and more salt. You can keep your LED hooked up in the circuit as you do this as well. Great job being curious! Do let me know what you find out!

Answer:  Cosmic Ray Detector

Hmm, if you can't see the vapor trails and you only see the mist or smoke, wait another 10 minutes for your system to get really cold. Put your hand on top of the jar to warm it (the side without the dry ice). Did you also turn off the room lights and use a flashlight to shine the beam through the side of the jar? If after waiting still no tracks appear, check to be sure you have an airtight seal. If not, tighten that lid and try again, and you can even add a little more alcohol first. You can also change the position of the jar - sometimes it's hard to see the tracks in certain positions, so you can place black paper behind the jar so it's not quite so see-through. If all those tricks don't help, I would use a larger jar and a different radiation source. Hope this helps!

Question: from Jennifer about the Cosmic Ray Detector experiment :

Hi, we're trying to do the cosmic ray detector with alcohol and dry ice. Followed to the letter as far as I can tell but didn't work - no trails at all. Please give some tips to increase the probability of this thing working. Thanks. Jennifer

Answer:  Diamond Kite

Yes, you can use the PVC to make the ROV or the Photoelectric Effect experiment!

Question: from andrea alfred about the How to use a Digital MultiMeter experiment :

We were experimenting with our digital multimeter and had a lot of fun. We combined this experiment with testing a circuit with LED. Everything with a low resistance reading also lit the LED, except when we tried saltwater! With saltwater the LED lit up dimly, and we had too high resistance to read on the multimeter. We wondered why? We thought saltwater would conduct electricity well. Do you have any idea what is going on?

Question: from Melanie Williamson about the Diamond Kite experiment :

oh man I bought 1" pvc pipes and some tape before reading the the questions, is there anything I can do with those?-Gabe

Question: from andrea alfred about the Linear Accelerator Project experiment :

We solved the problem. We used tape to hold the magnets because we did not have any elastics, and the sides of the magnets were covered in tape. When we cut the tape so the sides of the magnets were not covered it worked! I am surprised the tape was enough to stop it from working, do you have any idea why?

Answer:  Linear Accelerator Project

It's hard to know without seeing your actual experiment, but here's my best guess... if nothing happens, I would recheck the magnets before you fire it. It sounds like one or more wasn't in the right spot. Feel free to send me a quick video or photos to aurora@superchargedscience.com

Question: from andrea alfred about the Linear Accelerator Project experiment :

Hi, We built the linear accelerator, we are quite certain all the magnets were lined up correctly, but nothing happens. Do you have any suggestions what we should check?

Question: from Melanie Williamson about the Membranes experiment :

thanks.

Answer:  Eggshell Crystals

Hmmm... I have two thoughts. Either the bulk powder you bought isn't pure alum (there's something else mixed in), or the solution wasn't saturated and you just need to mix in more powder to make it work. You can heat the water so it can absorb more powder to be really sure it's super-saturated. Let me know how it goes!

Answer:  Membranes

No, but they do experience osmosis due to the difference in water concentration. Osmosis balances the water concentration between the high and low sides. There are several osmosis experiments in this section - enjoy!

Question: from andrea alfred about the Eggshell Crystals experiment :

We made alum crystals with alum powder from the grocery store and it worked fine, but later we bought alum powder from the bulk barn and have been unable to make crystals, we have tried a few times and never any crystals. Do you have any idea why?

Question: from Melanie Williamson about the Membranes experiment :

do the cells dissolve in the salt water?-Gabe's cousin Wally

Answer:  Detecting the Electric Field

I've had that happen to me also! It's usually from the friction of the wheels picking up a charge and then storing it on the grocery cart, and because it's metal it distributes the charge over the whole cart. And the wheels are constantly rubbing as you wheel your way down the aisle, so it's constantly picking up more and more charge. Notice that you only get a shock when you remove or place your hand on the cart... if you keep in direct contact with the cart, you don't constantly get shocked.

Answer:  What is Frequency?

Good question! You would treat it as two different problems, each with it's own pendulum string length.

Answer:  Spinning Ring

Can you send me a picture or video of what's going on? It's hard to tell when I am not right there next to you! You can send it to me at aurora@superchargedscience.com

Question: from Andrea Rosario about the Detecting the Electric Field experiment :

Hi Aurora, This was a fun experiment. Thank you! I was wondering how you can get shocked and/or have the ability to touch other people and shock them when you're in a grocery store. It comes from the metal in the cart, right? Why does it happen? I appreciate your time! Arteah Rosario

Question: from Karen Daley about the What is Frequency? experiment :

If something interferes with the string while the pendulum is swinging--but only on one side of its vibration path--and in effect shortens the string when it's going one direction in the vibration, how is the whole thing measured?

Question: from Amanda Mcabee about the Spinning Ring experiment :

I folded it both ways and it did not work why is this

Answer:  Laser Microscope

Try AMazon or the dollar store locally: https://www.dollartree.com/2-in-1-Laser-Pointer-Key-Chains/p338654/index.pro I've even seen them at hardware stores in the "impulse buy" sections near the cashier. Hope this helps!

Question: from Donald Stimax about the Laser Microscope experiment :

Laser light? not LED light? having a hard time finding a cheap laser light.

Answer:  First, Second, and Third Class Levers

Your problem sounds very much like it relates to a Flash Player problem. There has been some recent updates on browsers over the past couple of weeks. These update have in some cases, disabled Flash Player from automatically loading on pages.I'm not sure what browser you are using, or if you have checked with another browser, but I would make sure Flash hasn't been disabled. Here are a few links to the main browsers: https://helpx.adobe.com/flash-player/kb/enabling-flash-player-chrome.html https://helpx.adobe.com/flash-player/kb/enabling-flash-player-firefox.html https://helpx.adobe.com/flash-player/kb/enabling-flash-player-safari.html After making sure Flash Player is installed and enabled, you should then have no trouble with your video.

Question: from Katie Welch about the First, Second, and Third Class Levers experiment :

My video only has a 'play' arrow, no pause, rewind, fast forward, or timer to know where I'm at. Is there a way to change that?

Question: from Amanda Mcabee about the Straw Rubber Band Rocket experiment :

what could you use if you don't have skewers

Question: from Jennifer Tyrrell about the Detecting the Magnetic Field experiment :

We experienced the same phenomenon as Robert D'Angelo, and we experimented like he did. I moved the magnets completely out of the room. And the needle in the foam was still attracted to the sides of the bowls (different materials). It also didn't consistently go to one side of the bowl or the other. It appeared as though the foam or needle were attracted to the bowl. We added more and less water too. Same thing. Could it be static electricity in the foam?

Question: from Melanie Williamson about the Special Science Teleclass: Black Holes experiment :

awesome, thanks! -Gabe

Question: from Melanie Williamson about the What are Aurorae? experiment :

It must be cool to have something as awesome as that to have the same name as you.

Answer:  Special Science Teleclass: Black Holes

Maybe... and you might be the one to do it! :)

Question: from Melanie Williamson about the Special Science Teleclass: Black Holes experiment :

Thinking of how time changes with black holes, do you think we could use that science to create time travel?

Answer:  Pendulums

Yes! That's how generators work! They move magnets past a coil of wire, which causes a current to flow in the wire and can be used for all sorts of things! Great idea! You can make the motor generator project in Unit 11.

Question: from Johanna Durrett about the Pendulums experiment :

We made the chaos pendulum and it is really cool. We were wondering if a machine based on this design (magnets and pendulum) could be used to generate electrical power. If not, why not?

Answer:  Earthquakes!

There are four links after the last paragraphs of explanation under the video - do you see them?

Answer:  Electric fields are like Gravitational Fields

You are right - electrical charges are everywhere! When you get yourself a piece of tape, there's a static charge on the tape itself from un-sticking from itself (you can see this if you've ever tried to delicately tape two pieces of paper together, only to have them rise up to meet the tape when you hover just above the paper). When you take socks out of the dryer, slide down a plastic slide, and so on. You can build instruments to detect electrical charge like the "Electroscope" (http://www.sciencelearningspace.com/2013/08/cosmic-ray-detector/) and the "Alien Detector" (http://www.sciencelearningspace.com/2010/03/advanced-static-electricity-experiment-alien-detector/)

Answer:  Driveway Races

There are answers to each of the exercises, and you can also ask here! Did you watch the videos that explain acceleration yet? When you increase the steepness of the ramp, the acceleration of a soccer ball will also increase when rolls down. Think about it this way: Forces are vectors (which means that they have direction and magnitude), and the force of gravity points straight down from the ball toward the center of the earth. But the ball can't go straight down to the earth's core, it has to follow a ramp. That means that only part of the gravitational force (which is the accelerate the ball) points in the same direction as the ball's motion. If the ramp is horizontal, the ball would stay put because all of the gravitational force would be pushing on the ramp which pushes back and there's no motion in that direction. If the ramp were vertical, the ball would freefall drop with an acceleration due to just gravity. The steeper the ramp, the more the gravitational force is involved in accelerating the ball.

Question: from Megan Goebel about the Earthquakes! experiment :

where is the seismograph work sheet for this video?

Question: from Karen Daley about the Electric fields are like Gravitational Fields experiment :

In the static electricity and balloon activities, we purposely built up a negative charge in the balloon and then observed what happened in situations of induction and conduction. What about objects we come near or touch through out the day--what sort of electrical field changes or movements are going on, and is there a way to sense it?

Question: from Shelley Reid about the Driveway Races experiment :

We are new to Supercharged Science and haven't really learned our way around yet. Question number 4 on the excercises asks "what is the highest acceleration it can reach?" We are not sure how to figure out that question. If we don't understand how to answer a question, where can we go to find the explanation?

Answer:  Newton's Third Law of Motion

A rocket can travel through space because it's constantly throwing material out the back end which causes it to move forward. it doesn't matter if there's a vacuum or of the rocket is in an atmosphere... it's got to do with how the forces are applied. Do a search in the sear bar for "rocket teleclass" and watch it - it will probably answer a lot of your questions!

Question: from Aimee Cox about the Newton's Third Law of Motion experiment :

Can you explain how a rocket can travel in space? We learned that space is a vacuum so I don't know how it does.

Question: from joliekneen14 about the Basic Chemistry Safety Information experiment :

Safety first!

Answer:  Scientific Method Made Easy

You should have controls, including time duration and RR and FF. What kind of device are you viewing the videos from, and what browser?

Answer:  Underwater R.O.V. Robot

I am sorry I am not understanding your question... what is that you are looking for? The parts, or access to instructions, or something else?

Question: from Kelly Krampitz about the Scientific Method Made Easy experiment :

It would be nice if you included the controls to rewind and fast forward, as well as see how long the video is and how long is left. I cannot do this on my PC or Mac.

Question: from joliekneen14 about the What's a Joule? experiment :

Hmmmmmm,cool!

Question: from Christina Galvan about the Hovercraft Spaceship experiment :

The screen wont show up

Question: from Patricia De Lazzari about the Underwater R.O.V. Robot experiment :

I do not have it can you give it to me my son really wants to do it

Answer:  Microscopes and Telescopes

Anything under $100 for a microscope is going to be junk and frustrate you you enough to throw it away. I'd stick with a nice pair of binoculars (around $100-150) before buying a telescope to be sure you're really ready for one. The minimum for a telescope is around $400-600. Usually your local astronomy club will have "loaner" scopes for you to take home and test out before you buy one if you are a member of their club.

Question: from Olwen watkins Olwen watkins about the Specific Heat Capacity experiment :

cool

Question: from Olwen watkins Olwen watkins about the Microscopes and Telescopes experiment :

how much is the investment

Answer:  Cool Milk Trick

Let me know if it works... it should! Aurora

Question: from Andrea Albury about the Cool Milk Trick experiment :

is it okay if we diluted the milk already?

Answer:  Measuring the Speed of Light with a Chocolate Bar

Try moving the chocolate bar around - the second hotspot might be just beyond the edge of the bar.

Question: from Adilah Muhammad about the Measuring the Speed of Light with a Chocolate Bar experiment :

Our chocolate bar is only producing one hotspot. Are there supposed to be two hotspots? Our chocolate bar is 5.5 inches. Does this effect the outcome of the hotspots? Will we be able to continue with only one hotspot?

Question: from Lisa Pearson about the Flying Contraptions experiment :

cool! we built this and it was great.

Question: from Lisa Pearson about the Sensing Temperature experiment :

My son was fastened!
