craters
I didn't really get why we did this. I don't know how it will apply to mission to mars. We chose a golf ball as or object and were questioning wither the depth and width of the crater is directly or inversely related we chose directly. We learned the higher you drop it the father and wider the impact is.Also the smaller the object is the farther it goes without that much GPE.
I don't know what that means.

Body Power
we didn't finish but we got to the exercising. We did all the calculations and stuff. I learned new vocabulary and equations. I think we will be using this to mission to mars because it says astronaut a lot.

Motors
in this expeirement we were making solens. We wrapped wire around a straw attached it to a battery and put a needle in.
when the wire wasn't attached to the battery and you put the needle in nothing happened. But when the battery was attached the straw got really hot when you put the needle in.
also it sparked in my hand so i threw it was an accident I'm so sowwy

measure of sound
we didn't get to the speaker part. It sounded really cool and i want to do it.
In the first magnetic expeirement we were tring to find a pattern in how strong the magnetic feild is when you wrap peices of wire around it. We came up with the conclsion that the more you wrap it the higher the magnetic feild.
i didn't know that it would be hot when we put the wire on the battery but i burned myself.

Mini Culmination (part 4)
(I dont even know if we have to be doing blogs on this but I am to be safe.)
This week we tested the parachute in are group and it always landed on the second step. So now we are officially done with our parachute. Once again I asked around to see if people needed help.
I did'nt learn anything since I was doing little things like getting plastic bags and tape. Stuff like that.

Mini Culmination (Part 3)
My seprate duty out of my group is making a parchute that lands in the same spot and it always does out of the time we test it unless we move where we are droping it.
Since we were finished I went around my group asking if anybody needed my help and nobody did.
I eneded up somehow helping the other group with making a basket that carries stuff up a string using baloons. I did learn new things while help them like when your string is loose your basket doesnt go as far. Also I learned where you should but the ballons on the basket because if you ut it in certain places it wont move.

Mini Culmination (day 2)
Today since we got made a good working parachute we worked to make it better. We tried alot of new things. Alot of different wheight to see if our parachute could work for more than one size. In the end we came up with a design better than our first one.
I learned that in order for your parachute to fall flat the weight needs to be tied in the center so its balanced. Also that if you have a little extra wight you can make it fall smoother and faster depending on how small the item your transporting is.
A question I have is how come we just can't drop the iten into the bag.
