Answer:  Flashing Circuit

It sounds like you’re applying too much current to your circuit during testing. Go slowly and watch the video, and notice that I ask you in the video to recheck the wiring BEFORE ever connecting the battery, so you should not have exploding electronic parts.

Answer:  Getting Started With Digital Logic 1

What specific problems are you having with the videos? Can you take a screen shot and send it to me so I can see exactly what is going on? aurora@superchargedscience.com (Is there a black box and no play button, or does it look like a player but doesn't play when you click on it...??) Let us know so we can help you! And it sounds like you're applying too much current to your circuit during testing.

Question: from Johanijfick about the Flashing Circuit experiment :

my light emitting diode EXPLODED! I think it was the amp level.

Question: from Johanijfick about the Getting Started With Digital Logic 1 experiment :

Hi Im'e having some problems to play the videos. con you help me? PS: please give me some hard experiments the other ones were way to easy but please no capacitors in it (sometimes they explode)

Question: from violet639 about the Flying Over the Earth at Night experiment :

I should fly around the earth one day.

Question: from violet639 about the Flying Over the Earth at Night experiment :

Wow! That's a VERY cool video.

Question: from violet639 about the Inclined Plane experiment :

I know inclined planes. They're ramps.

Answer:  TaaDaaaaa!!!

Oh no! That doesn't sound right. I'll look into it and see what's going on. In the meantime, if you have issues like this, just send me an email so we can get right on it to make sure everything is working properly.

Question: from violet639 about the TaaDaaaaa!!! experiment :

This is one of my favorites!

Question: from violet639 about the Chicken and the Clam experiment :

Cool!

Question: from violet639 about the TaaDaaaaa!!! experiment :

Really simple.

Question: from violet639 about the TaaDaaaaa!!! experiment :

You know, I don't know why, but for 2 days, I couldn't comment. It said I had to be logged in to post a comment. I was already logged in. I clicked the link and even clicked remember me. I tried it twice and it wouldn't let me comment. Why is that?

Answer:  Fuel Cell Power

That's correct: an outside power source performs the electrolysis of the water which separates oxygen and hydrogen to power fuel cells. However, fuel cells have many advantages. They are a very clean and efficient source of energy, very reliable, lightweight, and long lasting.

Question: from jaylindberg1 about the Fuel Cell Power experiment :

This fuel cell still relies on another power source to work (the solar cell or battery) so whats the point in even having them? Why not just use the solar energy alone?

Answer:  Science Equipment: How to avoid being ripped off

Thank you for letting me know. It's hard to keep up with broken links when folks keep changing and updating their page urls! I've fixed these, so go ahead and refresh the page and try again!

Question: from msgulay about the Science Equipment: How to avoid being ripped off experiment :

The link for the Binocular, Telescope O-III filter and laser finder does not work.

Answer:  Meteorites

Oh no! There are other reputable places to purchase meteorites from - several good geology shops will have these for sale with certification.

Question: from msgulay about the Meteorites experiment :

Thank you! Just checked and NASA Space shop is out of stock on the $29.99 meteorites. I guess we'll have to wait till the next meteor impact on earth. lol

Answer:  Reading about Airplanes, Storms, and Bernoulli

The Bernoulli effect is still commonly taught as a part of flight theory. There are experts who say it's flat wrong and those who think it's a contributing factor in combination with other effects: Bernoulli and Coanda and Newton...oh my! :)

Answer:  Magnetism

I'd recommend purchasing a gem certified by the Gemological Institute of America. You can read their guide on moldavite here: https://www.gia.edu/gems-gemology/spring-2015-gemnews-moldavites-natural-fake

Answer:  Meteorites

Yes you can by them directly from NASA! https://www.thespaceshop.com/mefr3paco.html

Question: from msgulay about the Magnetism experiment :

Hello Aurora, I can't remember which video it was when you mentioned having a Moldavite ring. Is there a specific company you can recommend where we can get a moldavite specimen from to add to our Geology rocks/minerals collection? I read a few articles about how there have been lots of fake moldavites being sold in the market. And is there a way to test it and see if it is genuine or not?

Question: from msgulay about the Meteorites experiment :

Can you pls. recommend a website or a store we can buy these various rocks including an actual meteorite from? We would love to own an actual meteorite!

Answer:  Measuring the Speed of Light with a Chocolate Bar

Light travels in waves. The wavelength would be the distance between two peaks of a particular frequency. Microwave wavelengths are long compared to the range of visible light wavelengths that we can actually see.

Answer:  Bat Kite

Yes, humidity can be an issue! Not only does the air get "heavy" and really dense with water vapor, but the paper absorbs the water which makes the kite heavier. It sounds like your solution helped at least a little bit!

Answer:  Chicken and the Clam

Try different cans and note what happens. Absolutely try different blocks and see if it makes a difference. Change just one variable at a time so you can keep track and let us know how it goes!

Question: from abigail_shafer about the Bat Kite experiment :

SO, we ran into a little issue with this. We live near Houston, its summer, its been raining, ITS HUMID!!! We added a few pieces of tape to the inside and outside of the wing to give it more structure and keep the moisture from just collapsing the paper.

Question: from violet639 about the Measuring the Speed of Light with a Chocolate Bar experiment :

That's cool! But what does wavelength mean?

Question: from violet639 about the Chicken and the Clam experiment :

One more thing. Like say that the chicken noodle soup wins, and the tomato soup loses. Do you think that adjusting the size of the mega blocks ramp could possibly make the tomato soup catch up?

Question: from violet639 about the Chicken and the Clam experiment :

What if you substituted both cans? Maybe we could try chicken noodle soup (my favorite soup!) and tomato soup. Also, could you use mega blocks?

Question: from violet639 about the Play With Your Food experiment :

Cool! I didn't try it yet. I don't know if there's a scale. I'll have to ask my mom first.

Answer:  Sky in a Jar

Yes!

Question: from violet639 about the Bouncing Magnets experiment :

Cool! It's as if the magnets are floating on their own! :)

Question: from violet639 about the Sky in a Jar experiment :

Also, the liquid kind of looked yellow in the video. It looked like lemonade a little!

Question: from violet639 about the Sky in a Jar experiment :

Cool! Now, I live in a city. I think I'll have to shut all windows and turn out all the lights, right?

Question: from saturn about the Reading about Airplanes, Storms, and Bernoulli experiment :

So it is my understanding that the Bernoulli effect, while present, actually has very little influence on the lift of airplane wings and that the primary reason airplanes stay in the air is that the wings deflect the air downwards resulting in an equal and opposite force upwards. I refer to a NASA site on flight, and some others....Can you clarify this? Thanks- Sarah May-Anderson, PhD https://www.grc.nasa.gov/WWW/k-12/airplane/wrong1.html https://physics.stackexchange.com/questions/290/what-really-allows-airplanes-to-fly

Answer:  Circular Motion

We used 10 balls (not 20) :)

Answer:  Look Out Below!

In the case of the plastic bag, the force of air resistance (friction) is so strong and working in the opposite direction of the force of gravity. So the bag doesn't accelerate all that much and its velocity stays fairly constant. So it takes a relatively long time compared to the other options, which have less air resistance.

Answer:  Blow Gun Rocket

Very cool!

Question: from violet639 about the Circular Motion experiment :

Wait a minute. Why should it be 10 instead of 20?

Question: from violet639 about the TaaDaaaaa!!! experiment :

You know, I will try that. We'll have to buy eggs at the store first though. For now I tried only using a toilet paper tube, a book, and an eraser. You know what happened? The eraser didn't make it. I need help! Gabriel

Question: from violet639 about the Look Out Below! experiment :

How could the plastic bag take forever?

Question: from jennifer_comito about the Blow Gun Rocket experiment :

I made a cool car rocket launcher. It fires a small toy car

Question: from maryannpalko about the Simple Pulley Experiments experiment :

We had the same problem with this experiment, as did others, specifically needing more coins added to the lift in order to get the load up. When it did move up, it moved all the way to the top of the pulley. Even when we tried to gently tugged on the string, results would vary (the load/lift) would remain exactly where we let go of the string. Please explain. And for the answer given above regarding the response,"mastering 2nd year engineering students," could you please expand. Thank you

Answer:  Why bother with seat belts and helmets?

Hmmm - what do YOU think?

Question: from violet639 about the Why bother with seat belts and helmets? experiment :

why use a liscenced driver

Answer:  Speed and Velocity

The exercises are the last link in the navigation on the right hand side of the page. Here's a direct link: http://www.sciencelearningspace.com/premiumcontent/docs/Ch1-1D-Kinematics-1-StudentWorksheet.pdf

Answer:  TaaDaaaaa!!!

What do you think will happen? Try it and let us know how it goes!

Question: from violet639 about the TaaDaaaaa!!! experiment :

Could you also use orange juice if you substituted the marble for an egg? I mean like will the juice stop the egg before it breaks at the bottom?

Question: from violet639 about the TaaDaaaaa!!! experiment :

maybe i will use a tomato

Question: from violet639 about the TaaDaaaaa!!! experiment :

Looks simple! I haven't tried it yet but i will soon

Question: from laurene_ross about the Speed and Velocity experiment :

Hi, I was wondering if there was homework pages for this lesson, if there are any where would they be located.

Question: from cccdrtt about the Sponges and Cnidarians experiment :

I never knew jellyfish tentacles were hollow!!!

Question: from cccdrtt about the Ray-Finned Fishes, Lobe-Finned Fishes, and Sharks! experiment :

What kind of fish were in the shark video?

Answer:  Turning Water into Wine

Hi there! So sorry for the confusion! Phenolphthalein is an indicator of acids and bases. It's colorless with acids and turns pink with bases. Phenolphthalein is used to test in the range of pH of about 8-10. I apologize for an error s- I'll check on that and get it corrected right away.

Answer:  Electroplating

Thanks for the clarification - I'll make sure it's clear which connections are which for you!

Question: from roboshort about the Turning Water into Ink experiment :

By the way, is our ferric ammonium sulfate solution and sodium ferrocyanide solution combo supposed to result in a dark blue liquid with dark blue sludge? Ours did. (We actually used potassium ferrocyanide to substitute the sodium ferrocyanide) The Short kids

Question: from roboshort about the Turning Water into Ink experiment :

Is there a name for the product of our ferric ammonium sulfate solution and potassium ferrocyanide solution mix? We did this experiment with our cousin, and we had a great time while learning a lot! Thanks Aurora, The Short kids

Question: from roboshort about the Electroplating experiment :

Thanks Aurora!

Question: from roboshort about the Electroplating experiment :

Hi there, In the student worksheet instructions for this experiment (which was really cool by the way) you told us to connect our batteries in series and then told us to connect them in series again but in a different way which our dad said was actually connecting them in parallel.

Question: from roboshort about the Turning Water into Wine experiment :

Hi there, we had a blast with this experiment. Along with the sodium carbonate solution, we tried: imitation vanilla flavor, soy sauce, Frank's Red Hot, lemonade, sodium bicarbonate (baking soda) solution, and soapy water. We found that some were acids, some were bases. We did, however, have a little confusion as to how we would know if our liquids were an acid or a base since in the student worksheet you said," You should understand that phenolphthalein is an acid/base indicator that stays clear in the presence of an acid but turns colors in the presence of a base." but on the experiment page with the video on it you said,"Phenolphthalein is a weak, colorless acid that changes color when it touches acidic (turns orange) or basic (turns pink/fuchsia) substances." Does it stay clear when it touches an acid or does it turn orange? Based on the rest of the information, we concluded that phenolphthalein turns clear when it touches an acid and changes color when in contact with a base. Thanks Aurora, The Short kids

Question: from sticklerfam about the Simple Hovercraft experiment :

You said in the little intro above the video that you can make it zoom across the table and you gave us a hint, add another balloon. can you tell me where to put it or how to do it?

Answer:  Jawless Fish

It's actually a very distinct, special material. It doesn't dry out like normal slime or gel would, and it has thread-like proteins that make it very strong. Scientists are studying it now to find out more about its composition and potential uses.

Question: from cccdrtt about the Jawless Fish experiment :

Is the slime like slime you make at home or like a gel substance?

Question: from cccdrtt about the Arthropods experiment :

Even though I have very acute arachniphobia, [ fear of spiders] I really enjoyed this article. Thanks Aurora!

Answer:  What do I do with Ammonium Chloride?

Right, but you don't want to dispose of Ammonium Chloride down the drain as it can be toxic to aquatic life. You can read more about handling it here: https://beta-static.fishersci.com/content/dam/fishersci/en_US/documents/programs/education/regulatory-documents/sds/chemicals/chemicals-a/S25168C.pdf

Question: from roboshort about the What do I do with Ammonium Chloride? experiment :

Hi there, how should we clean up from this experiment? I'm assuming we should rinse three times, wash with soap and water, and rinse three times again.

Question: from renatavergilis about the Making Litmus Solution and Paper experiment :

Thank you so much! :) Nate (8)

Answer:  Rusty Balloon

The chloride in the salt combines with the metal to rust it. You should be dumping out the water, but try it both ways to see if it makes a difference in your results!

Answer:  Making Litmus Solution and Paper

Yes, ethyl will work. Denatured alcohol is ethyl with a few additives.

Question: from renatavergilis about the Making Litmus Solution and Paper experiment :

Will ethyl or isopropyl alcohol work? Thanks! Nate(8)

Question: from roboshort about the Rusty Balloon experiment :

Also, How come we added salt? Does it aid the corrosion of the steel?

Question: from roboshort about the Rusty Balloon experiment :

Hi there! In the video you had us soak the steel wool in water and then dump out the liquid, leaving the steel wool inside the bottle, capped with a balloon. In the written instructions, however, you didn't mention whether or not we should discard the liquids. We are trying the video method of dumping the liquids out. Which method should we have followed? or does it matter?

Answer:  Ball Bounce

Hmmm... what do YOU think? And then try it! (And then let me know what you figure out - what happened, and why?)

Answer:  TaaDaaaaa!!!

A tomato sounds fun ... and messy! Maybe try it outside first?

Question: from violet639 about the Ball Bounce experiment :

can the force of throwing it down also affect the bouncing part?

Question: from violet639 about the Ball Bounce experiment :

I loved this experiment! I tried it with a small yellow ball. As I listened to the lesson, I kept dropping the ball on the table. It didn't bounce high because it wasn't high enough. When I tried it over the floor, it bounced a little higher!

Question: from violet639 about the TaaDaaaaa!!! experiment :

Could you use a tomato

Question: from violet639 about the TaaDaaaaa!!! experiment :

Cool experiment

Answer:  Bobsleds

It means to adjust and notice what's going on and adjusting again.

Answer:  Bobsleds

Sure!

Question: from violet639 about the Simple Pulley Experiments experiment :

Can you use marbles in one cup in pennies in the other?

Question: from violet639 about the Bobsleds experiment :

What does tweeking mean??

Question: from violet639 about the Bobsleds experiment :

Could u use an empty toilet paper tube as well?

Question: from violet639 about the Bobsleds experiment :

The Bobsled word does sound a little funny.

Question: from violet639 about the Magnetic Sensors experiment :

That's a big circle!

Answer:  Planetarium and Star Show

You are correct that sound doesn't travel through space. Even if they did, the sun's vibrations are usually at a frequency that is much to low to be heard by human ears. Scientists measure the waves, translate them into motion (aka sound) waves, then speed them to a frequency where we can hear them. You can learn more about this here: http://www.sciencelearningspace.com/2013/09/song-of-the-sun/

Answer:  Newton's First Law of Motion

Yes, all of the sections in the High School physics section have these for you to download. Enjoy!

Question: from jenjar2001 about the Newton's First Law of Motion experiment :

I really like the workbook and want one for all the other sections too please:)

Question: from thegoffclub about the Planetarium and Star Show experiment :

How do we hear the song of the stars (sun) with our human ears when sound cannot be heard in space?

Answer:  Yeast, Mold, and More!

Oh wow - that's exciting! Sounds like you learned something too! :) I recall doing a similar thing with my pond water sample I was saving for weeks in the trunk of my car for a water purification class I was teaching. When I finally uncorked it, the entire school (except our class of course) was forced to evacuate because it was so strong!

Question: from Shannon Acevedo about the Yeast, Mold, and More! experiment :

So the written instructions say not to put the lid on tightly when growing the protozoa with the yeast and grass in the jar. Well, we did. Oh my goodness! Will we ever get that smell from our nasal passages???? About as stinky a smell I've ever smelled.

Answer:  Terraqua Column: How does water affect land and animals?

So the water can travel ("wick") between the two places. If you really want to be a scientist about it, you can try all sorts of materials (nylon, yarn, twine, etc) and see which works best.

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

why cotton string?

Question: from littlelisa94 about the Iodine Clock reaction experiment :

My KI is in crystal form. What concentration solution should I make for this experiment.

Question: from kkruid about the How to Avoid the Dentist experiment :

cool thanks for the information.

Answer:  Making Sandstone

Any craft store should have it! Try your local Target or Walmart as well.

Question: from renatavergilis about the Ammonia Experiments experiment :

Thanks a lot! The link really helped. And now I know what (II) and (III) mean.:) Nate (8)

Question: from julienl_g about the Making Sandstone experiment :

Where can you get Plaster of Paris?

Answer:  Detecting Plaque

Nope - it just stays there for a bit while you inspect your teeth for places you really need to brush better!
