sceince objectives 6

Observe and describe the evidence of energy transfer in a closed curcuit.

We made the lightbulb light by connecting the wire from the battery to a switch and connected a wire from the side of the switch to a lightbuklb and connected one more wire from the end of the lightbulb to the battery.

science objectives 5

We connected a wire from a D-cell battery to a switch and connected another wire from the other side of the switch to a lightbulb. Then we connected a wire from the lightbulb to a motor then connected that wire to the lightbulb. My group and I use the switch to turn them off and on.

Science objective 4

Describe how magnetism can produce electrical current and electrical current can produce magnetic forces.

We connected a wire from the battery to the switch and we connected a wire from the
other side of the switch and wrapped it around the electromagnet. Then we connected that wire to the battery and used the switch to turn the electromagnet off and on to pick up as many washers we could.

Science Objectives 3

Describe magnetism as a force that can push or pull other objects without touching them.

Our class learned about magnetism and found out there is an invisible field around the magnet called a magnetic field. The magnetic field pushes or pulls everthing in the field depending on if it is iron or a magnet. If it is iron it will pull the object and if it is a north sided magnet face the north side of the other magnet they will repel. If it is a south sided magnet facing the south side of the other magnet they will repel also and if the north side of a magnet is facing the south side of another magnet they will pull togther or attract.

science objectives 2

Describe how magnets forces attract and repel each other and certain materials.

We went around our classroom to find out what attracts to magnets and what didn't. We found out that the only thing that stick to magnets are things made out of iron and other magnets. If a north pole of a magnet is near another north pole the will repel same with south poles, if a south pole is near a south pole they will repel and if a north pole is near a south pole they attract.

If one balloon is charged it will attract and if both of the were charged then they would reple
If one balloon is charged it will attract a balloon that is not charged and if a charged balloon is near a charged balloon they will repel same with uncharged balloons, a uncharged balloon with repel another uncharged balloon
