Materials:
1 AA battery
Aluminum foil
Scissors
Procedure
Cut a strip from the aluminum foil
Then attach both ends of the aluminum foil
Results The aluminum wires gets hot.
Why? Touching the wire to the ends of the battery produces a path through which electrons travel(an electric circuit). The electrons move out of the negative end of the battery. The movement of the electrons causes the wire. When a light bulb is placed in the electrical circuit,the electrons heat up the wire filament inside the bulb. The wire filament becomes incandescent, that is it gets that it gives off light.

Experiment: Charge It!
Materials:
Static Tester
12 by 12-inch piece of clear plastic wrap
piece of silk fabric
"test" objects (wooden Popsicle stick, plastic straw, plastic comb, metal spoon, metal scissors, glass eyedropper, glass light bulb)
Step 1 - Rub the wooden Popsicle stick with the plastic wrap for about 30 seconds.
Step 2 - Bring the Popsicle stick near on end of the folded card on your static tester. Don't the stick touch the card. What happens Static Tester?
Step 3 - Record your results on the chart be Use"strong", "weak" or "none" to describe the Static Tester's Motion.
Step 4 - Repeat steps 1 to 3 with each of the other test objects.
Step 5 - Repeat 1 to 4 but this time with each object with the silk fabric.
Results:
Test Item Plastic Wrap Silk Fabric
Wooden Popsicle Stick Yes Yes
Plastic Straw Yes Yes
Plastic Comb Yes Yes
Metal Spoon Yes No

In this course, it also includes friendship and group work to finished most of the experiments and tasks. If we have no friendship and group work the bank of china tower won't be even built. Everyone will be selfish, even you are the leader and no ones in your team thats useless. I think the most important to make a friendship you need to be trusted and loyalty to another.

Short Circuit Experiment
I did a little experiment based on short circuiting, I put a piece of aluminum foil and a AA battery. Then I connect each end of the battery to the foil and wait for 2 or three seconds, then it will be burning hot. That's a short circuit.

Machine Mania Blog
Hi! There whoever in the world is reading my webpage, Welcome!! This is a blog dedicated to Machine Mania (like what do you think??) In this website, you will see cool links to all machinery and nice pictures of special rockets. This website is also about my automobile processes of production for Machine Mania course in Hong Kong International School. Oh! by the way, my name is Peter Sin and i am going to Chinese International School in HK. This summer course is quite boring and fun (obviously). My Automobile is going to be the flat and fastest . I wanted to make it that way, but that going to be kind of impossible, right or not?
