they would not come. they need fruit to make them come. by the way the name at the top is my moms. i have 25$ am i cool?. Aurora are you homeschooled like me? .

Question: from Brook Batzel about the Eco-Column: experiment :

the fruit flies will not come onless you put fruit in. by the way the name at the top is my moms name.

Question: from Kelly Deibler about the Magnetic Tornadoes experiment :

Ever time we log in there no videos...Kind of feel like this program is not as user friendly as it could be...My kids love science and so sad they hav missed out this year...

Question: from Lisa Kennady about the Setting a Homeschool Schedule experiment :

I like the idea of the set times and set routines to keep structure. My kid certainly needs it and my day is easier because of it. However I disagree with the blanket advice to get other things such as errands done before school so that the parent is able to focus better. I believe that your kid's physical and mental energy levels, and THEIR best times of day, should be the primary factors driving the daily schedule. I would only put errands first if they were truly time-bound. It's less work for me to motivate my kid when he's at his peak, and he is happier and enjoys school more when he's mentally ready for it. I have had to be very creative about getting the rest of my tasks woven into the day. Below are examples of how I get things done, if anyone actually cares to read. I schedule the more difficult subjects for the time of day my kid is the most mentally alert. My son (8yrs old) gets up at 6:30am and says he's ready for school. You would think the kid just had a shot of adrenaline or something! Although I am tired, and more of an afternoon person, I skip my shower and put on yesterday's clothes and start school immediately because his energy level and attention are at their peak FIRST THING. I hop in the shower after school and enjoy a longer shower without the rush. It's a trade-off I make so that school is easier for him, and therefore less constant "encouragement" is required from me. My "morning child" is mentally tired in the afternoons, so we only do the more right-brained or physical activities then. I also tell him, "If you get all the classes done in the morning, we can do ... whatever fun thing... afterward". This often motivates him to get school done faster so we can for example hit the playground or library after school. As far as getting errands done, I have cars-chooling options I use for when I need to drive somewhere. I use "The Story of the World" on CD for world history, which he listens to as we drive. There is a test booklet he can take after each chapter right there in the back seat. For some reason he thinks it's totally exciting to do school while we drive, because we are not stuck at home! We have done school while driving, in the doctor's office waiting room, in airport terminals, riding in the grocery cart, waiting in line at the recycling center, etc. Buy or make flash cards or study sheets that you can quiz them on for times like this. You will be surprised what you come up with when you HAVE TO get errands and school done simultaneously.

Answer:  Newton's Second Law of Motion

Hi Zac, Thanks for writing! I would recommend practicing as much as you can - there are lots of different websites with practice tests out there you can access for free: https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=ASVAB+practice It looks like there are also good study guides online here: https://uniontestprep.com/asvab/study-guide/general-science/pages/1 http://www.asvabpracticetests.com/asvab-general-science-practice-test/ http://www.cram.com/flashcards/general-science-asvab-full-test-836701 Hope this helps! Aurora

Question: from Jennifer Carroll about the Newton's Second Law of Motion experiment :

hey there its Zac I need your help. I want to take the ASVAB in May but Im struggling in the science portion of the test can you recommend a study method that would help me

Answer:  TaaDaaaaa!!!

The first law is about inertia: "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." So before you set the experiment in motion, you're observing things at rest - that's the 1st law. When things are in motion, that's also the 1st law, only it's a little harder to observe because there are other forces acting to slow down and stop the motion. The second law is about the forces are not balanced and things are moving: force is proportional to acceleration. The more you hit the pan, the faster (and further) it flies. Newton's third law is about forces coming in pairs. When you stand up, your weight pushes on the ground, and the ground pushes back with the same amount of force (otherwise you'd be moving if it wasn't balanced; equal and opposite). Before the experiment starts, the cup is pushing down with it's weight on the table, and the table is pushing back on the cup. Does that help?

Answer:  Latching Circuit

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

Answer:  Microwaving Soap

Hi Jazz, Great idea trying the different soaps! I am guessing some soaps had more water content than others... the puffed ones had more than the melted ones. Color isn't usually a factor in experiments like this. Enjoy!

Question: from Candyce Ovadal about the How to use a Digital MultiMeter experiment :

Which 20 should I use? There are 3. (20, 20m, and 20k)

Question: from Prity Parikh about the TaaDaaaaa!!! experiment :

We need help to ans the second ques: The first Law is observed with the plate on the cup staying put unless we hit it with our hand. The second Law (?) maybe The force(gravity) acting on the ball as it falls? Or the force on the plate which sends it flying? - The third law - (above) cup on the table

Question: from Julia Raudenbush about the Latching Circuit experiment :

We don't have access to either relay video. Can we do the latching circuit project without them? We have the K-8 program, so the latching circuit video is available but not the relay videos. Why is that? :{)

Question: from Student Science about the Microwaving Soap experiment :

Hi Aurora Hello all the way from London England. We have done the experiment but because we are from England we could not get Ivory soap. so we decided to base our experiment on which type of soap works the best we used, Dove, Sainsbury Basic and Pears. Sainsburys worked the best it just went in to a big lump of puff it was not as big as Ivory but it was still big and we think we put it in a bit too long but it was still very cool. The Dove was looking good but when we took it out it just deflated and still had the lumpy puffy kind of texture. However, the Pears soap just melted but Pears was seethrough and was not white it was orange. Do you think the colour and the fact that it was seethrough changed the results? what do think Aurora. from Jazz (aged 10)

Answer:  Latching Circuit

There's a couple of different relay videos you might be looking for: http://www.sciencelearningspace.com/2011/10/use-a-relay-as-an-electromagnetic-buzzer/ http://www.sciencelearningspace.com/2010/04/relays-homemade-shockers/

Question: from Julia Raudenbush about the Latching Circuit experiment :

Hi! The lesson and the video mention a separate video on the relay, but we can't find it. Under materials, the link takes us to the shopping list for unit 11, but there is no relay mentioned on the list for Unit 11. Help!

can satic electric light do it i can see it when i rud my head on my pillow and im not allowed to do YouTube.

Answer:  Detecting the Gravitational Field

Ever watch someone jump off a boat into a lake? They dive one way, but what happens to the boat? It goes a little bit in the opposite direction, doesn’t it? Why is that? Let me explain. Imagine blowing up a balloon. Blow up an imaginary balloon, but don’t tie it off. The instant you let the balloon go, point with your finger the way the air INSIDE the balloon goes. Now point which way the balloon goes. Did you notice that they were equal and opposite? That’s Newton’s third law. Here's another example: Hold your arm out in front of you and push against a wall… the wall is pushing back with the same amount of force (it doesn’t just fall over)! That’s Newton’s third law – equal force, opposite direction. The wall matches the size of your push. It doesn’t push more than you do. And when you let go, the wall stops pushing (it doesn’t push harder). That’s what we call a reaction force. For every action, there is an equal and opposite reaction. Said another way, forces come in pairs. The thrust from a rocket shoots out the back and the rocket moves forward. Does that make sense? You can read more about it in Unit 1 & 2.

Question: from Delia Ayer about the Detecting the Gravitational Field experiment :

Why would we go in the opposit direction of a ball that we tossed in space?

Answer:  Hovercraft

You can find the right motor here: https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&productId=154915&langId=-1&catalogId=10001&ddkey=https:CookieLogon This link is from the main parts list here: http://www.sciencelearningspace.com/2016/08/radio-shack-component-replacements/

Question: from Delia Ayer about the Hovercraft experiment :

But your "squished" motor in the video didn't have a gear on it. Is there any place I can get one like that?

Answer:  Hovercraft

No - those are usually press-fit on, and you need a machine to get them off. However, I've had luck heading up the motor shaft (get an adult to do this for you) and then quickly pressing the hot gear-shaft end into a propeller and melting the prop right onto the hot shaft. Make sure when you do this you've got a soft, bendy type of plastic propeller or it may not work.

Question: from Delia Ayer about the Hovercraft experiment :

I got some hobby motors but they have gears Instead of a plain old shaft. Any ideas on how to get them off?

Answer:  How to use a Digital MultiMeter

It depends on what the range of volts or amps are that you are testing. For most of the circuits in our program, the 20 setting will work just fine. If you're getting a zero reading, then switch it down to a lower value, and if it's pegged too high then you'd switch it up a decimal place or two.

Question: from Candyce Ovadal about the How to use a Digital MultiMeter experiment :

What I mean is, what setting does it need to be on to test a circuit board?

Answer:  How to use a Digital MultiMeter

It depends on what you want to do. For the video, put it on the "20" setting.

Question: from Candyce Ovadal about the How to use a Digital MultiMeter experiment :

What setting does it need to be on?

Question: from Candyce Ovadal about the Building Speakers experiment :

ok thanks.

Question: from Brook Batzel about the How to View the Sun Safely experiment :

its easy use a telescope

Question: from Candyce Ovadal about the Wireless FM Transmitter (the 'Bug') experiment :

ok, thanks

Answer:  Hovercraft

First of all, awesome job making it work at all and building it yourself! Here are some things to you try to make it even better: 1. Put in a fresh 9V battery - does that help? 2. Remove the battery and hold it above the hovercraft in your hand, so its weight isn't on the hovercraft any longer... does it move faster now? 3. Make sure that there are no air leaks around the perimeter of the hovercraft where it contacts the table. I noticed when I made mine from paper that it would always have air leakage problems. When I switched it out for a foam plate, those issues totally disappeared. Hope this helps! Great job! Aurora

Question: from Delia Ayer about the Hovercraft experiment :

I built it but it moves forward very slowly, I don't know if that is because I used a paper plate for the base or if I have two of the same motors? Other than that it works fine.

Answer:  Underwater R.O.V. Robot

The wire Al recommends in the video is cat-3, which means there are three wires bundled inside one outer casing. You can alternatively use individual 18/2 lamp wire, you'll just have three separate wires going from the control box to the motors. You can twist them together by holding down one end of the wire (ask a kid to hold it for you) and insert the other three wires into the chuck of a drill and slowly rotate the drill (turn it on) to twist the wires together to do the same job as the cat-3. Does that help?

Answer:  Redox Reaction

Not yet - this is one of our newer experiments that we are still writing content for. Thanks for checking!

Answer:  Door Knob Touch Alarm

Tell me specifically which transistors you are missing, and I'll see if I can contact the company and get you replacements. I'll need part numbers and identification numbers for the exact ones you want so they get it right the first time.

Answer:  Rolling Clock

You can probably still have it work just fine. Send me a picture (mailto: aurora@superchargedscience.com) with a clear close-up of what's going on and I'll see what suggestions I can make.

Answer:  Hovercraft

Answer:  How to use a Digital MultiMeter

Yes absolutely!

Answer:  Building Speakers

Look in the shopping list for Unit 14 - they are the neodymium magnets. There should be an order link as well for easy purchase.

Answer:  Wireless FM Transmitter (the 'Bug')

Excellent - great job! If it transmits any further, you'll need an FCC license, so no... this is the one with the longest range that we found available, so hope this works out ok! :)

Answer:  Reading about Atoms, Elements, Molecules, Acids & Bases

Viscosity is a measure of how thick and sticky a fluid is. Honey has a high viscosity. Rubbing alcohol has a low viscosity. Viscosity changes with temperature, and it's generated by the internal friction of the molecules inside the fluid.

Question: from Delia Ayer about the Hovercraft experiment :

Why do you need the shroud to be elevated?

Question: from Candyce Ovadal about the Rolling Clock experiment :

We were soldering the lights on and one of the solder pads actually burnt, it turned black. We only held the soldering iron on for a max. of 2sec.. I did not want to solder all the rest of the lights on if it was not going to work, so will the project be ruined now?

Question: from Candyce Ovadal about the How to use a Digital MultiMeter experiment :

Can I use my multi-meter to test a circuit board that isn't working?

What is viscosity?

Answer:  Radio Shack Component Replacements

Unfortunately that is permanently out of stock. We bought out the last of their supply when we heard it was going to be discontinued so we could still include it in our Science Mastery programs. It's possible to still complete the activities, however you will need to gather individual components for the circuits. I did see a few on eBay and Amazon.com for sale that you might want to check out.
