1. An axe

2. Wedge

3. Automatic screwdriver

4. Screw jack

5. Office chair

6. Sliding board on children playground

7. Staircase

8. Ladder

LESSON TWO – ADVANTAGES OF INCLINED PLANE

1. An axe is used to slide wood.

2. Wedge is used to cut wood.

3. Automatic screwdriver is used to screw a nut.

4. Screw jack is used to lift up a car.

5. Office chair is used for balance and position.

6. Sliding board is used by children on playground.
