3. Energy

4. Electrical Energy b Electricity is very important in our lives. b We would find it very hard to do without it. b There are so many things in our homes that are powered by electricity that we have begun to depend on them. b Imagine you woke up this morning and had no electricity. What difference would it make to your normal morning routine?

5. Mains Electricity b Most of the large appliances in our home are powered by Mains Electricity. b Mains Electricity is a supply of electrical energy b Mains appliances change or convert this electrical energy into other forms of energy b Can you name them?
