megnatic connection

for our first experiment it worked out really well the magnet on the end shoot out I wish we could have taped it and slowed it down so that we could see it happen. We where able to learn how magnetic connections work out.
the other eximent it also worked really well. the magnets diconected and the the magent swong back and connected back to the magnet

A mesure of sound

every time we wound the wire around the nail the magnetic force went down some. the wire would get really hot and it burned trought the tape a couple times

motors: a magnetic movement

in magnetic movement we learned when we put a pin in a pass thingy. when the pin went in the straw the pin would want to get out of the straw as fast as possible. it would like jump out of the straw. we also learned how to start up a motor because we connnected both the sides to make a surcate.

heat shealds

today we did heat shealds. for my first on I put the lunimim around the bult and screw. then the other thingy stuff. and the screw was showing at first and it only wnr 25 secs then i covered the screw and it went 25. then i conected the thingy stuff to the screw so the luminum wasnt touching the scrw
