Static Electricity

During Science Week Ms. Shields did an experiment with us all about static electricity.

Static electricity occurs when an electric charge builds up on an object.

This can happen by rubbing certain things together. 

We rubbed a balloon against our jumpers and put it close to our hair. The static electricity made our hair stand up!!

The static electricity made the balloon stick to the wall!!

 

 We did an experiment to see which material produced the most static electricity!

We needed:

Different materials: wool, nylon, cotton, tissue, silk.

Balloon

Rice Krispies

How we did it

We rubbed each piece of material with a balloon.

We made the rest fair by rubbing each material the same number of times with the same balloon.

We counted how many rice krispies the balloon picked up after being rubbed on each material.

 

 

Results:

Wool and Nylon produced the best static.
