Question: from beckytubbsandcrew about the Easy Steps to Award-Winning Science Fair Projects experiment :

I don't know how to make a data sheet.

Question: from mcclellandah about the Can Insulation Save Energy? experiment :

why no video???

Answer:  More Sensors

Electricity in your house is very dangerous and should never be used in your experiments. The batteries in the experiment only provide 3 volts DC and less than an amp of current. But the electricity in houses is about 110 - 220 volts AC and 15 to 20 amps! Although the principles would be the same, controlling the light of your room isn't possible using the supplies in this experiment.

Question: from alena110 about the More Sensors experiment :

Would you be able to take the first vid's Tilt Sensor and instead of turning on a small LED light, turn on or off the main light of your room?

Thank for catching that - I'll get this fixed for you.

Answer:  Shopping List for Unit 17

Oops! Sorry about that - I've uploaded the correct file, everything should be fixed now.

Answer:  Star Gazing

Thanks for catching that! I've posted the worksheet right under the video, and added a link to do more stargazing with the new set of lessons that I just created! Enjoy!

Question: from amanda_milke about the Shopping List for Unit 17 experiment :

The shopping link above only takes you to a page that says the following and doesn't actually have the shopping list on it. I just copied and pasted the list into a word document to print it out no biggie but I think that's what everyone is talking about. Unit 17: Life Science Part 2 www.ScienceLearningSpace.com Appropriate for Grades: Grades K-8 (see notes on each lesson) Duration: 3-25 hours, depending on how many activities you do! Living things are all around us. Sometimes the living things we notice the most are animals, whether its birds chirping in the trees, our pet dogs, or even our fellow human beings. However, most living things are not animals. In these sections, we will learn about bacteria, archae, fungi, protists, and plants. These organisms are extremely important to learn about. They make life possible for animals, including human beings, by keeping soil ready for growth, and providing oxygen for our survival. No life would be possible without these remarkable organisms.

Question: from aabbott1221 about the Star Gazing experiment :

In your video on Star Gazing, you mentioned a star log that you made and you want the kids to download and print. We can't find it. In the questions, another kid asked about it, and your answer includes a link to find a template. That link is "temporarily unavailable." Any other suggestions?

Answer:  Stirling Engine

Use a circle cut from a sheet of paper - it isn't critical how big it is - just make it about what you see in the video.

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

There is a typo in the Kinematic Equations on the top of the Student Worksheet. The t was omitted where the vt should have been. This error was carried into the solution for practice problem #14. The total time of 15.5 seconds was also used for the second leg of the pilot’s fall where 12 seconds should have been used. The time was also not squared and the deceleration of 2.5 m/s should be negative. When using the corrected equation, the proper time, negative acceleration and squaring the time; the distance of the second part of the fall is 228 meters. This makes the total fall of the pilot 288 meters. Using d=1/2 (Vi+Vf)t is an easier equation to use to determine the distance of the second part of the fall which produces the same result of 228 meters where Vi= 34 m/s, Vf= 4 m/s and t=12 s.

Question: from daviddebo about the Stirling Engine experiment :

Where is the circle template? The "template" link only has the template for the crankshaft.

Answer:  Stirling Engine

You can use a top of a water bottle - it's used in the CD to attach it to the coat hanger. Watch the video to see how it's used.

Answer:  Thermometer

If you find that too much of the liquid is evaporating, it may not work to compare the temperature overnight. As an alternative, place your bottle in a container filled with ice water. The fluid level in the straw should go down within a matter of minutes. Take the bottle out of the ice water and set it back on the counter. The level should return back to the center, but give it about half an hour. Then set your bottle in a container filled with hot water (only hot water from the faucet. Don’t do this on a stove top and don’t put your bottle in a pan heated on the stove!) After a few minutes, the fluid level in the straw should rise.

Question: from daviddebo about the Stirling Engine experiment :

Where can we get the nylon bushing?

Question: from staceyldent about the Thermometer experiment :

Each time I top off and bring our liquid up to the original marked line, it will evaporate and the level drops into the bottle. What should I do? Thank you!

Answer:  Steamboats

It was from one of our students - fun, isn't it?

Question: from shanesdeals about the Steamboats experiment :

whats that third video i know what its doing but did you do it or did someone else

Answer:  Detecting the Magnetic Field

Yes, it sounds like static could be the issue. Try using a bowl made of glass. Also, in the video, we mention using a small container so the foam/cork isn’t floating all over the place. However, feel free to try the experiment in a larger container or even a sink or bathtub. You only need the water level to be high enough for the foam/cork to float.

Question: from teri_drinkwater about the Detecting the Magnetic Field experiment :

Our experiment mostly failed. We tried large cork, then cut it smaller, then realized that even without the metal rod, the cork was attracted to the edge of the ceramic bowl. Is this possible static electricity interfering with the magnetic force?

Answer:  Football Ice Cream

Yes, you should have access to this ice cream experiment. I'll have Tonya connect with you to check to see if your account is set up correctly. ALso, find the liquid nitrogen video here on this page: https://www.sciencelearningspace2.com/science-with-aurora/spring-break-camp

Answer:  VEX IQ Robotics

About 361.9 million square kilometers!

Answer:  Mystery Toy

It's the name of this particular experiment! Can you figure out how it works?

Question: from nabby1776 about the Mystery Toy experiment :

Hey Aurora What's the mystery toy

Question: from nabby1776 about the VEX IQ Robotics experiment :

How big is the OCEAN?

Question: from ps91two about the Football Ice Cream experiment :

Hello, is there a way to access your Football Ice Cream (Liquid Nitrogen Ice Cream)? You mentioned it in today's class and my sons are very interested in making it. Thank you, Lisa

Answer:  Telling Time by the Stars

The current TIME = the clock reading MINUS twice the number of months after March 6. If it is April 6, then you are subtracting 2 from the time you read on the clock. If it's May 6, then subtract 4. Does that make sense? Also note that if it "daylight savings" (usually March - Nov), then you have to account for that extra hour as well. Try it tonight and see how you do!

Question: from klrhudy about the Telling Time by the Stars experiment :

I don't get how you did the correction factor. Can you explain it? Thank you!

Answer:  Special Science Teleclass: Renewable & Alternative Energy

The phenomenon described in the experiment has also been explained as the Cheerios effect and is attributed to behavior due to surface tension (not magnetism). I'm thinking that the attraction of the cereal is a combination of magnetism and surface tension. So, here is my two part answer. I hope this is accurate: 1) Since the north and south poles are on opposite sides of magnets, they are happiest connecting end to end. This provides a very slight force that encourages the pieces to form a straight line, which presses the lineup against the curve of the bowl. 2) The attraction of molecules in liquid causes a membrane on the surface of the liquid. This is part of the phenomenon called surface tension. (That's how water strider bugs can walk on water) This causes the cereal pieces to make a slight "dip" on the liquid's surface. Surface tension also causes the liquid to slightly curve up or down along the edge of the bowl. The combination of these two concepts causes the pieces to appear to be attracted to the edge of the bowl.

Answer:  VEX IQ Robotics

Ben and Joseph both do live events and post matches afterwards: https://www.youtube.com/watch?v=Af0xQV-IcZE Here's their main website: https://www.studentroboticseducation.com/ The VEX IQ official headquarters do not allow general public to watch live events to protect the kids, but you can often find VEX events published after.

Question: from lorin_mcguire about the VEX IQ Robotics experiment :

where can I just watch a challenge without buying the entire VEX challenge set?

Answer:  Why do birds migrate?

Look here: https://en.wikipedia.org/wiki/Flight_feather https://www.sciencelearn.org.nz/resources/308-feathers-and-flight

Question: from mcclellandah about the Steamboats experiment :

cool

Question: from curlychemist about the Special Science Teleclass: Renewable & Alternative Energy experiment :

my mom helps me in since because she used to be a chemist your since is awesome!

Question: from curlychemist about the Special Science Teleclass: Renewable & Alternative Energy experiment :

We did the cereal magnet experiment. We were wondering why the cereal gravitates to the rims of the palate and not the meddle? C= 1 2 3 4 5 6 7 8 9 10

Question: from osomama2 about the Why do birds migrate? experiment :

what feather is the most important when it comes to migrating? All of them, or are a couple of feathers more important?

Answer:  What a Drag!

It can be difficult to maintain a constant speed by hand. It may be that slight variations in the drag speed are allowing friction to slightly take hold. Also, dragging certain materials across glass causes a static attraction. That attraction would cause the need for an increase in force to keep the book in motion. If possible try the experiment on a surface other than glass.

Answer:  Simple Switches

That's right, there isn't enough power in the two AA batteries to give you a shock. That's why it is important to only try this experiment with the batteries recommended in the supply list. You are safe from getting a shock in this experiment because the voltage provided by two AA batteries isn't enough to overcome the electrical resistance of your skin. But it is important to only try this experiment with batteries recommended in the supply list.

Answer:  Advanced Telescope Building

Yes you can - the larger the lenses/mirrors, the more light your telescope will be able to collect and the brighter the images you'll see!

Answer:  Retrograde Motion

ALL planets exhibit retrograde motion. It doesn't make sense to include the Earth because it's your reference point, so by "all" we mean all 7 planets.

Answer:  Watch Your Weight

Sorry for the trouble - here are the answers to the questions above! 1. (d) all of the above 2. FALSE. Gravity accelerates all things equally. Which means all things speed up the same amount as they fall. 3. TRUE. Gravity does pull on things differently. Gravity is pulling greater on objects that weigh more. 4. On planet Earth, the golf ball has less drag in our atmosphere, so the ball will hit the ground first. On the moon, they will hit the ground at the same time. You can try this with a ping pong ball and a golf ball - both hit the ground at the same time. Then try a basketball and a marble. Which one hits first? 5. If you aim at the monkey, the dart will hit the monkey. Once the dart exits the gun, there’s only one force acting on it with any significance: gravity. And only gravity is acting on the monkey after he loses his grip in the branch. The constant acceleration due to gravity affects both the monkey and the tranquilizer in the same way. The dart falls a little bit below the initial aim and by the time the it travels the horizontal distance to reach the branch, the monkey will have fallen the same amount as the dart in the vertical direction, leading to impact. The speed of the dart does not matter.

Question: from alena110 about the Simple Switches experiment :

How come you don't get shocked when you touch the paperclip and turn the circuit 'on'? Is there not enough power in the battery to do so? Just asking.

Question: from mark_ruby about the Advanced Telescope Building experiment :

can the mirrors be 50mm diameter 38mm diameter

Question: from gracielabecerra2009 about the Retrograde Motion experiment :

Hello! Not really understanding this one in general unfortunately. Also, #3 says all planets spin in retrograde motion but I read earth does not. Can you please help me? Thank you!

Question: from gracielabecerra2009 about the Watch Your Weight experiment :

Hello! Could I please get the answers to the first 3 questions please? Thank you!

Answer:  Watch Your Weight

No, because the "answers" you get are totally dependent on how much YOU weigh!

Question: from grayson97 about the Watch Your Weight experiment :

Do you have the answers for the questions?

Question: from yulipop79 about the Microscopes and Telescopes experiment :

Is Gskyer a good telescope company.

Answer:  Microscopes and Telescopes

I am not really familiar with this brand. What happens if you use it to look at the moon?

Answer:  Simple Hovercraft

Sorry for the confusion with the links! The second thruster is when you add another balloon, and somehow make it so that the end of the balloon is horizontal (you can use a straw taped to the open end to help you with this - I used a clothespin to keep the air from coming out while I was putting it together). You need some kind of *push" in the horizontal direction to make the hovercraft move forward. I've found that a smaller balloon works well for the thruster, because anything larger made mine go off balance. Give it a try!

Question: from yulipop79 about the Microscopes and Telescopes experiment :

My telescope is made by Gskyer. Is that ok?

Question: from 6expats about the What a Drag! experiment :

Hi Aurora! I had the same problem as someone else back in the comments. I put my big book on my glass desk and did the experiment and I had a greater stretch when it was at a constant speed than when I had to get it moving. Both of our problems happened on a glass surface. Could that be affecting it? If so why?

Answer:  Benham’s Disk

Probably need more SPEED! What happens if you "blur" your eyes (don't try to focus so hard) and then look straight at the center of the disk?

Answer:  Pinhole Solar Projector

No Stellarium is meant for stars, not our sun specifically. There are two other websites that will show you rea time views of the sun you can use to track sunspot activity: https://sohowww.nascom.nasa.gov/data/realtime-images.html and http://halpha.nso.edu/

Question: from valerie_guenther about the Benham’s Disk experiment :

HI, we printed out the disks on a black/white laser, assembled them on hard paper and spun them with a drill. We saw no colours except black, white and grey. Any suggestions - different printer

Question: from alena110 about the Special Science Teleclass: Electricity experiment :

Okay, thanks!

Question: from lauriedopkins about the Pinhole Solar Projector experiment :

can you use stelleriam web to track the sunspots

Question: from 6expats about the Simple Hovercraft experiment :

Hi, sorry if I sent this twice. I posted it and it did not show up. I was trying to make the thruster with another balloon for the hover craft, but I was Unsuccessful. At first I taped a balloon to the back of the balloon on the hover craft, blew it up, and let the air out so it made the whole thing topple over. Then I added a cap to the new balloon to regulate it’s power, but that didn’t seem to do anything. So I looked through the comments and saw that you had posted a link on how to do that. But it brought me to a page where it showed the different grade levels with pictures above them. I was wondering if you could send another link or if you could just teach me how to do it. Have a nice day!!!!

Question: from 6expats about the Simple Hovercraft experiment :

Hey Aurora, I looked through the comments and saw that you posted a link for how to make a thruster using a balloon in order to make it zoom across the table, but when I click the link it just brings me to a page that shows all the grade levels in a list and then next to that it shows the grade levels with pictures above them. I was wondering if you could resend the link, or maybe if you could teach me how to do it. I tried taping another balloon behind the first one controlling the air with another cap, but it didn’t seem to do anything. When I did it without the cap, it made the hole thing fall over. Can you please help me? Have a nice day!

Answer:  Shopping List for Unit 1

I would say, "sometimes". It depends on your hardware store. You can really choose any magnets, but if you're going to purchase magnets online, then look at Unit 11 and order those at the same time so you have everything you need. The ones for Unit 1 are donut shaped so you can easily hang them, and rare earth for the magnetic array for the laser pulse experiment (upper level). I would start by using what you already have and see if it works before purchasing anything.

Answer:  Special Science Teleclass: Electricity

To get started with electricity, work through Unit 10, then Unit 11 (magnetism) and then jump over to Unit 14. There's a lot of content in there. So glad you know what you like! Units 1-6 are the basics physics of motion, unit 9 is all about light (something you'll need to learn if you want to do electronics) and 3 and 8 are all about chemistry. It's a progression, but can you skip around and do it in any order.

Question: from alena110 about the Special Science Teleclass: Electricity experiment :

I am a little confused. I know this is off topic (I didn't watch the vid yet) and I have finished my 8th grade science early. I guess I'm supposed to do the other fields of science, but I really like electronics, and decided to do this for the rest of my year. But here's my question: is there a Unit 1: Electronics? Because the farthest I see it Unit 10, so I just wondered of there was a Unit 1 as well.

Question: from tania_kac about the Shopping List for Unit 1 experiment :

Hello, are the 2 rare earth magnets and the donut magnets common enough to be sold at regular hardware stores? Are the materials (rare earth) and ceramic magnets ( donut magnets) important? Thanks

Question: from shanesdeals about the The SeeSaw experiment :

whats a first class leaver cause i answered the question [question 3] with seesaw but my only options were hammer, crowbar, and scissors.

Answer:  Pinhole Solar Projector

No, Stellarium is for locating stars, not seeing live images of the sun. There are a couple of places to view the sun: https://sohowww.nascom.nasa.gov/gallery/bestofsoho.html http://halpha.nso.edu/

Question: from lauriedopkins about the Pinhole Solar Projector experiment :

can you use the the Stellarium software to view real time pics of the sun for the sunspot pinhole solar projecter .

Answer:  Harmonicas

You need something that will vibrate and have some elasticity to it - you can do string or similar, but you'll need to pull it tight.

Question: from akochowi about the Harmonicas experiment :

Do I have to use thik ruber bands?

Answer:  Part 12: Cells

There's only a "worksheet" for the first part. HOWEVER I just published a whole new page with a month's work of BIOLOGY LABS here: https://www.sciencelearningspace2.com/science-with-aurora/february-biology Enjoy!

Question: from ronald_rohe about the Part 12: Cells experiment :

Hi I can't find the worksheet pages for part 12- 27 in high school biology is there a workpage? ~Emily Rohe

Question: from mark_ruby about the Eco-Column: experiment :

can you put frogs and tadpoles in it

Question: from Sasha about the General Relativity: Gravitational Waves experiment :

Ok. Thanks for the link! It's really interesting. I hope we find out what matter and dark energy are in the future.

Question: from Sasha about the Two Spaceships Show Time Dilation experiment :

So the light beam moves at the same speed for both observers, but for the person on the asteroid, he sees it takes a longer time to move back to the other ship, than for the observer on the moving ship?

Question: from amyclineotr about the Watch Your Weight experiment :

There are still no answers to questions 1 – 3 of the download handout. Thanks!

Question: from 6expats about the Net Forces experiment :

Thank you!

Answer:  Eco-Column

It's a little small for tadpoles and frogs - use a larger container and you should be alright.

Answer:  Worms!

You can learn about worm reproduction here: https://unclejimswormfarm.com/composting-worm-reproduction-how-worms-reproduce/ I purchase his worms for my garden, and they are so much fun to take care of in a worm farm!

Answer:  Mystery Toy

Yes, I am sure you can get it to work - give it a try!

Question: from mark_ruby about the Eco-Column experiment :

This is Jeremiah can you put tadpoles and frogs in it

Question: from danikadunn about the Worms! experiment :

How do worms reproduce?

Question: from grayfeatherlove about the Characteristics for Circular Motion experiment :

hi, it's Wyatt, I have been thinking about something I am very unable to figure out. so photons are waves. if you shake an electron one of these things is produced, an electric field turning into a magnetic field then electric etc is what a photon is. these photons spread out like butter. but unlike butter, they spread in 3 dimensions if I am correct, so if they spread themselves out along with their energy (amplitude), then how do other electrons absorb them if they are spread out in all directions? or do they just travel in a single direction like an electron or proton and do not spread out unlike butter. thanks wyatt gray

Question: from lorin_mcguire about the Mystery Toy experiment :

What if you use a toilet paper roll and a rock?

Answer:  Net Forces

I think that Question 8 is somewhat confusing, and here's why: 1) It doesn’t tell us which scenario to consider. 2) The first sentence says the rope isn’t moving but then the same sentence says one force is moving down. 3) It doesn’t tell us if the rope is above the ground or resting on it. This might be a better way of thinking about it - here's a re-write to #8: If the rope was slightly off the ground, with gravity pulling it down, what does that tell you about the force you and your friend exerted? Then we can answer that question like this: Some of the force you and your friend exerted was pulling the rope up.

Answer:  General Relativity: Gravitational Waves

Although they sound similar, black holes and dark matter are different. A black hole is formed when a very big star at the end of its life shrinks down to an extremely dense object with a very strong gravitational pull. That pull is so strong that even light can’t escape. So black holes have a high concentration of gravity in one spot. Dark matter is material that is spread out across the universe. It has gravity but is unlike anything we’ve seen before. This link has more information on dark matter: https://spaceplace.nasa.gov/dark-matter/en/

Answer:  Star Gazing

No, unfortunately not. That would be a really cool option, though!

Question: from causfahl about the Curiosity Rover Successfully Lands on Mars on August 5th! experiment :

i agree with Ching-Yu Hsu. SO COOL!!!!!!!!

Question: from youngsurrender about the General Relativity: Gravitational Waves experiment :

Do black holes have something to do with "dark matter"? Just a side thought.

Question: from youngsurrender about the Visualization of Einstein's Special Relativity experiment :

I'm going to have to let this sink in...

Question: from 6expats about the Net Forces experiment :

Hi Aurora! Could you please explain to me the answer to number 8? “If the rope wasn’t moving, but you only had one force moving down, what does that tell you about the force you and your friend exerted?” I put that it would mean that me and my friend wouldn’t be pulling (therefore not applying any force.) That would then leave only one force moving down, which would be gravity. Can you explain the answer you put please, and tell me why mine is wrong? I hope you have a great day!
