Magnets

Objective: Describe how magnets force attract and repel each other and certain materials.

Answer: We got a whole bunch of objects and we showed which ones could stick and which ones could repel. The magnets stick to things made out of iron.

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.

Static Electricity

Objective: Predict the effects (attract or repel) of an electrictrostatic force on the motion of charged and uncharged objects.

Answer: One balloon will stick to your head or your pants. The balloons will repel when they are charged.

Series Circuit

Q. Observe and describe the evedince of energy transfer in a closed series circuit
A. Hook up a wire to a battery and a light bulb then a nother wire to the other side of the light bulb and the other side of the battery and then you have your light bulb working.

Science quistion #3

Q. Describe magnetism as a force that can push or pull other objects without touching them.
A. Magents use force by the north pole and the south pole.

Electro Magnet

How do the parts work on an electromagnet...

With this electromagnet you can turn on the swith because there's a process were the electricity flows from the battery to the switch the through big black wires that go around the rivet and send a signel witch makes the magnets work through the end of the rivet then goes back and repeats over and over.

Q. Describe how magnetism can produce electrical current and electrical current can produce magnetic forces ( e.g., building electromagnets)
A. Through a perfectly wired telegraph
