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 redwineh about the Solar Boat experiment :
Can I use a super duper strong LAZER to make the solar panel work?
Question: from laura_black about the Rock Candy experiment :
In the salt and vinegar crystal experiment, the vinegar is really important because it helps the salt dissolve better in water and makes the solution a little more acidic. This allows more salt to be in the water at first, which is important for forming crystals as the water dries up. The vinegar isn’t needed in the rock candy or borax experiments because those materials (sugar and borax) already dissolve well in water without help. Rock candy forms crystals from sugar, and borax crystals grow just by heating and cooling the water.
The sponge is another important part of the salt and vinegar experiment. Its tiny holes, or pores, give the salt crystals lots of places to stick to and start forming. The sponge also soaks up the liquid and spreads it out, which helps the water evaporate faster and lets the crystals grow more quickly. In the other experiments, things like strings or pipe cleaners are used for crystals to grow on, but they don’t absorb liquid the way a sponge does.
If there’s leftover salt in the pot for this experiment, it’s actually a good thing! It shows the water is fully loaded with as much salt as it can hold, which is perfect for crystal-making. In the rock candy and borax experiments, leftover sugar or borax isn’t okay because it can mess up how smoothly the crystals grow. Those experiments need the solution to be completely clear, with everything dissolved.
So, vinegar helps the salt dissolve and makes the water better for crystals. The sponge gives the crystals a place to grow and helps the water dry faster. And leftover salt in the pot just means there’s plenty of salt ready to form crystals when the water dries.
why did we need the weak acid (vinegar) in this experiment and not the rock candy or borax experiment to form crystals? How does the porous sponge effect the experiment? And why was it okay to have left over salt in the pot and not in the other crystal experiments?
Question: from Aurora Lipper about the Moon Sand experiment :
Moon Sand is a nickname. It isn't technically dirt or sand.
Question: from marlenalucas about the Moon Sand experiment :
Yes, you need to use vectors, and if you're not familiar with how to break down a vector into its x and y components using trigonometry yet, there's an introduction to them here a few lessons back: https://www.sciencelearningspace2.com/2014/10/using-trigonometry-with-physics/
Question: from Aurora Lipper about the Hovercraft experiment :
Yep, this is related to maglev. However, the concept of combining air cushions with maglev is a newer concept.
Question: from Aurora Lipper about the Lava Lamp experiment :
The video is there. Please be sure that you are logged into your account. If you still can't see it, please try a different web browser.
Question: from khansamahmood1 about the Lava Lamp experiment :
where is the video
Question: from ammonwil about the Helpful Hints experiment :
Problem number 5 on the worksheet is giving us trouble. We didn't understand how to split the Velocity into the X and Y components. So we initially got the answer wrong and then looked at your answer. We understand that you split the 73ft/s into X and Y by taking the 73sin45 and 73cos45. However, you say that those equal each other. We understand that they seem like they should equal each other since both are 45deg from the X and Y axis. However, when we type that into our calculators we don't get the same thing and also we don't get the same answer that you did. We can't figure out how you got the 51.6ft/s. None of the calculations we can see in your answer give us the 51.6. We understand the rest of the problem, just not this very important initial step. Can you help?
Question: from blackhole_rider1 about the Hovercraft experiment :
"Scientists are already planning future ACVs to use magnetic levitation in addition to the air power… but it’s still on the drawing board."
Is that different from Maglev that has been in use since 1984? If different how?
Question: from Aurora Lipper about the Crystal Radio experiment :
The magnet wire, resistor, and diode are available from https://www.jameco.com/
Question: from Aurora Lipper about the Galvanometers experiment :
Jewelry wire won't work for this project. You'll need to use magnet wire because it has a thin epoxy coating that projects from short circuits. It isn't practical to coat regular wire with nail polish, because you could have spots where the wire remains bare.
Question: from Tatiana about the Galvanometers experiment :
I have jewelry wire (0.4 mm) that is labeled 'special copper wire for jewelry'. Can I use it instead of magnetic wire? I have five colors, silver, gold, copper color, black, and reddish. For the black and red wires, it looks like a black or red coating over some silver wire, but it is really thin and I'm not sure if it is actually silver, or the orangey copper color. I'm not sure if it is real copper. Is there a way to test it for copper? Would copper work? Would I need to coat it in clear nail polish first?
Question: from mgonzalez1226 about the Crystal Radio experiment :
Were can I find the materials?
Question: from redwineh about the MIT Leg Lab experiment :
Can I make a three legged robot with my lego mindstorms kit?
Actually, calcium carbonate is added to sugar to increase the rate, size and shape that sugar crystals form! You can try both calcium carbonate and also sugar on their own, and also mix together a third solution with both to see what kinds of results you get with all three. As a scientist, you get to do the experiments once you have great questions like these to work with!
I am sorry for the error on the worksheet! I've updated the answer page to include solutions for all three.
Here's the direct answers to your questions:
To calculate the distance the frog has traveled in the horizontal direction, use the formula Distance= speed * time
where the speed in the x-direction is 7 m/s and time is 0.5 seconds to get the frog travels 3.5 meters horizontally.
For problem 2, the initial vertical velocity is 2 m/s and acceleration due to gravity is 9.8 m/s^2
so using the equation for max height:
h = (vertical velocity)^2 ÷ (2g) gives 0.204 m (20.4 cm)
On problem 1 in the Advanced Pop Rocket Lab worksheet:
Wouldn't the x displacement be solved separately from the Y displacement? Assuming this is correct, I solved for the X direction with D=V*t. This is what I got: D=(7m/s) * (.5s)
D=3.5m
On problem 2:
Now I'm considering the y axis. Using your equation from the lab Yf=Yi-(Vyi^2)/2a.
Yf=0-(2^2)/(2(-9.81))
Yf=.204
These aren't the answers on the answer sheet. Did I do something wrong?
My answer on number 3 was the same as your answer on the sheet, and I used the same equations and technique.
This mystifies me :)
Question: from amberdawnbook about the Building Speakers experiment :

Question: from barrnun36 about the Color Streak experiment :
Hi I can't find a geology rock bag that has all the rocks we need, we only have 3 of the rocks. Do you have any links to bring me to what we need.? Thanks
Of course! You'll find material lists that include order links when we need specific items. Otherwise, you can use the rocks you have in the backyard or in a personal collection if you'd like. The important thing is to learn about the testing techniques. We have several sets we recommend depending on which experiments you'd like to do. Here's the 4th grade shopping list: https://www.sciencelearningspace2.com/standardcontent/docs/4th-earth-science-shoplist.pdf - do you see the link in the PDF for the kit?
Those are great questions! I would test different amounts of each to see which works best!

Question: from barrnun36 about the Mohs’ Hardness experiment :
I'm trying to find the rocks and minerals to order. Not having much luck finding everything. It would be really nice to have a link to help with that. It’s really frustrating to find everything we need. I have no knowledge of rocks and minerals so it's taking us a to long to get started. Thanks Amy
Yes, in the Live Class / Recordings section - you'll find them listed each week near the end of each student handout worksheet. You'll also find them in the monthly review sessions we do for each topic in the live classes.
Hi Aurora! We are enjoying all the science experiments and videos. My son and I are both learning a lot, lol! I was wondering if there are vocabulary words available for the lessons. It just occurred to me to ask, in case I've missed them. If not, I can certainly make vocabulary lists to use. I wanted to check with you before I did that though. Thank you for this amazing science curriculum, and the math too! Our family and friends cannot believe how much Ian is learning!
Question: from sunnysolace about the Jupiter’s Jolts experiment :
can I use a Styrofoam carryout containers instead of a plate? we have some unused ones.
Question: from nikki_wankum about the Force-full Cereal experiment :
We had some Neodymium magnets (Stronger than normal magnets)and although they didn't move very much, he was able to get some movement. COOL!
I followed the procedure except I replaced the tomato juice with lemon juice, and it didn't work. I tested the connection and heard a pop which means the connection it good. Why won't the lemon juice work.
LEGOs are notorious for breaking apart. The LEGO Mindstorms set is pretty old, so if he's ready for the next step, please check out VEX IQ Robotics, which are much more robust.
Any recommendations on keeping the blocks together when the robot is moving? We have one of the RCX sets and every time my kiddo designs a robot and gets it going it crashes and breaks apart. Could it be a setting that needs to change or maybe sticky glue, a stronger base? any suggestions would be helpful, Thanks.
Question: from jalglin2011 about the Pinhole Camera experiment :
