sound

today jackie and i mesured the power frequency on the computer. we put wire attached to a pencil on the end of baterys and measurd the frequency for 4 winds. it was really interesting to see how the power fluctuated. te wire on the the battery got really really hot. it was cool. we never figured out how to make a speaker. it was really complicated

body force

today we learned about excersize in space. first took our height and weight and then we measured our heart weight. ten i had to run around for 2 minuets and then i took my heart rate. in space u always ave to make sure you excersize so your not fat and weak back on earth

creating craters

today i worked with kimmy to creat craters by dropping a golf ball from a certain number of inches into a pan of flour. it was really cool and we discovered that the higher your ball was dropped from teh more it sped up, therefore causing a bigger reaction/crater. it was pretty fun but very messy. we had to do three tries on each thing to make sure there was no human error. after we finished measuring things we dropped from different heights such as 36 inches and that made the deepest crater. dropping from 5 inches made a very shallow and low impact crater.

magnets

today we did a magnetic lab. we were supposed to place the magents about 2.5 inches away and then drop a ball so they would collide and another ball wuld fly off the end. sort of like an abicus. It was really hard to disconnect the magnets because they were stuck together so tightly. e never actually got to see the end result becuse the magnets were crazy stong and we couldnt get them apart! but it was really fun and i cant wait to see another group do it. it seems like an interstgin reactio
