[this is school]

So, a couple of days ago, Gabby, Jackie and I attempted at doing the magnetics lab.. I'm disappointed to say, we didn't get too far on the lab.. We were supposed to build the Gauss Rifle.. There were these 4 small block-shaped magnets that had a very strong magnetism. To build the Rifle, you were supposed to tape each magnet 2.5 inches apart from each other. Each time I taped down one magnet, and was taping down the next, the other magnet would come off the tape and ruler and snap onto the other magnet... Because of how strong the magnets were, and apparently how weak I am, it took either forever for just one person to pry them apart, or took 3 min for 2 people to pry them apart... pretty sad... So we finally figured out a better way to set it up... we had this metal/magnetic beam on the counter and decided to mount the magnets on that instead. Then behind each strong, block magnet, you were supposed to place 2 round ball magnets. -In the picture they were also supposed to lay flat.. which is where we encountered our "final" problem... the magnets, for some reason, WOULD NOT LAY FLAT!! One thing I wondered about this lab, once we ran out of time, was how the Gauss Rifle would have worked (had it been set up correctly..).. well, that's the last lab of this segment of labs!

Today, Sam, Gemma, and I did the Motors Lab. We finished the first lab.. We coiled wire around a straw and stripped the coating off the ends... we then attached the ends to the battery and insterted a needle half-way into the straw and it got sucked in!! We started on the next lab.. Making our our Motors.. but when I tried it, it didn't work as it did in the diagram.. the wire loop was supposed to spin around, but it just fell out.. I learned how much power/ magnetic power there is to be able to pull a needle into a straw.. I'd really also like to know why the second lab didn't work.....

the picture is of the 2nd lab..
