3. Lesson.1: Static Electricity Objectives State how an object gains an electrostatic charge. State which type of materials can gain a static charge through friction. State which type of materials can gain a static charge through friction. Explain the experimental observations using your knowledge of electrostatics. Explain the experimental observations using your knowledge of electrostatics. P.4 Radiation for Life

4. Static Electricity : Charging by friction Some materials become positive when rubbed giving electrons to the cloth. The charge of the cloth is equal and opposite to the charge of the rod. Some become negative taking electrons from the cloth.

5. Static Electricity : Law of Charges Like charges repel Unlike charges attract

6. Complete the Electrostatic Circus of experiments. For each experiment 1 – 5, write the number of the experiment, follow the instructions and answer the questions in full sentences in your exercise books. We will go through the experiments when they are completed.

21. Learning Objectives Describe and recognise that insulating materials can become charged when rubbed with another insulating material. State that there are two kinds of charge: positive; negative. State and recognise that like charges repel and unlike charges attract. State and recognise that electrostatic phenomena are caused by the transfer of electrons. Describe static electricity in terms of the movement of electrons: a positive charge due to a lack (or loss) of electrons; a negative charge due to an excess (or gain) of electrons.
