Pupils in Third and Fourth class carried out an array of experiments during Science Week

The following experiment  Separating Pepper from Salt explored energy and forces.

Pupils learned how to separate pepper from salt using a balloon.They rubbed a balloon  against their  hair  and learned that small particles called “Electrons” transferred  from their  hair to the balloon.These electrons have a negative electrical charge that draws to it the salt and pepper which have a positive electrical charge(opposites attract).But the pepper which is lighter than the salt will be drawn to the balloon from a bigger distance.
