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

robox

We finshed our robot today and it was to heavy t first but then we fixed it a couple time so now it can go forward with out tipping over. It has the claws that will be able to grab the thing up. I think the only thing that might go wrong is that the parachute wont land on the first step, or the robot will tip over if its to heavy. But Ithink next class we will be able to prefect everything so not to many things could go wrong.

robox

We started right off the bat and got a lot of things done. We where able to get a lot of the arm done. But I think its going to be to heavy. I hope when we have to pick the thing up our robot won't tip over. Our robot I think will have a cran. But I'm not sure if the cran will be able to pick every thing up. So we might use the claws instead.

Robox

We didn't have very much time to start our robot but we did the bod done and we started on the arm. We had a group meeting and decided that Rhys and I should be doing the robox. We assigned jobs so that we knew who was going everything. I think it will be kinda hard to do the mission but I think if the parachute lands fine that we will be able to get the stuff to the place they need to.
