1 Let’s rip! Can you rip/tear/cut the pieces of paper into the SMALLEST pieces possible please?

2 Electrostatics

3 Let’s see what we need to know

4 Electrostatics 1. There are two types of electric charge (positive and negative) Hi! Hola!

5 Electrostatics 2. Opposites attract

6 Electrostatics 3. Static charges can be produced by the action of friction on an insulator Plastic, amber, glass, Perspex

7 Electrostatics 4. Electrons are negatively charged

8 Electrostatics 5. Objects are charged positive by the loss of electrons cloth

9 Electrostatics 6. Objects are charged negative by the gain of electrons Only electrons move, that’s why they call it electricity! cloth

10 Electrostatics YouTube - Refueling Fire Caused by Static Electricity YouTube - Refueling Fire Caused by Static Electricity 7. Static charges can be dangerous

11 Electrostatics 7. Static charges can be dangerous

12 Electrostatics 8. Static charges can be useful

13 Electrostatics 8. Static charges can be useful

14 Electrostatics YouTube - Bill Nye the Science Guy - 25: Static Electricity 1/3 YouTube - Mitsuba Systems - Sprayright Series 700 Powder Spray System YouTube - Bill Nye the Science Guy - 25: Static Electricity 1/3 YouTube - Mitsuba Systems - Sprayright Series 700 Powder Spray System 8. Static charges can be useful

15 Draw the sentence 1.2.3.4. 5.6.7.8.

16 Draw the sentence 1.There are positive and negative charges 2.Opposite charges attract and like charges repel 3.Static charges can be made by the action of friction on an insulating material 4.Electrons are negatively charged 5.Objects are charged positively by the removal of electrons 6.Objects are charged negatively by the addition of electrons 7.Static electricity can be dangerous (aeroplane refueling and gas stations) 8.Static electricity can be useful (painting, photocopiers and removal of smoke from chimneys)
