craters lab

today alice, lilly, and i did the craters lab. it was really fun to play with the flour. there was an obvious pattern in the drops (inches):
the compass ball's width increased by 1/4 each time (every 2 inches)
the ping pong ball' width increased by 1/2 the fist time and stayed at 3 for the rest
the golf ball's depth incresed by 1/2 each time


:P

motors lab

so today we did the magnetic motors lab with me, maddy and rose. the first part of the experiment we did and i didn't work but then we realized that we had to tape it on both ends and it worked. the second part of the lab was kind of confusing and i tried to make it but i didn't strip enough green stuff of the copper for it to work. it was fun and i liked trying out different situations to get it to work.

recovery systems

today we played with parachutes. madeira, taryn and i each made our own parachute. taryn's bag was cut in half so it was smaller and had a hole at the top. madeira's bag didn't have a hole at the top and it broke. mine had 4 strings and a hole. the hairdryer kind of burnt it so we went to the stairs. it went pretty smooth but then one of the strings broke and it flew much softer.
