Conclusion 1 Pupils discuss the answers.
2 Teacher guides pupils to make conclusions based
on their discussion.
Follow-up Pupils complete the worksheet given. (L3/WS2).
L3 /APP1
Factors That Animals Compete For.
a) Competition for food and water. Food and water are the basic needs of animals. Competition
occurs when the food and water resources are limited. If the food and
water resources are abundant, animals do not need to compete for
them.
b) Competition for mate. Competition for mate occurs among the same species of
animals. Animals need to mate to ensure the survival of their
species. Competition occurs when two male animals fight for a
mate.
L3 /APP2
c) Competition for space and shelter Competition occurs when animals are looking for shelter or
defending their own shelter. Animals also need to be in control
of certain space that provides them with food, water and
shelter.

Allow vehicles to

Enable us

Allow us to walk or run
without slipping
Enable us to sharpen
a knife ADVANTAGES
Waste energy
Produce heat that damages
parts of machines
Cause surfaces to wear-out
e.g. Tyres, Sole of shoes
DISADVANTAGES
L14/WS1 Name : _________________________________________________ Class: ___________________________ Date: _________________ Read the following text and then carry out the task below.
Friction is a force that opposes the movement of an object. Friction only occurs when two surfaces are in contact. Friction is useful in our everyday life. Friction allows us to walk
or run without slipping. Without friction, we will not be able to walk or
run on the ground. Friction also allows vehicles to travel on the road
safely. The brake system in the vehicles makes use of friction to slow
down or stop the vehicles. A friction enables us to hold things because
it prevents the objects from slipping. Friction enables us to sharpen
knives and other tools.
Despite all these benefits of friction, it can also cause problems
in our everyday life. Friction makes objects move slower. We need
more energy to make them move faster. Friction can also cause
surfaces to wear out, for examples tyres and sole of shoes. Friction
produces heat that damages surfaces or parts of machines.
Use the coloured pencils to underline the answers for the following questions: 1 What is friction? (blue) 2 What are the advantages of friction? (green) 3 What are the disadvantages of friction? (red)

Conclusion Teacher guides the pupils to make conclusion that
preserving food has many advantages.
Follow up Pupils list the importance of preserving food.
L23/APP1
The Importance of Preserving Food
Food can last longer if it is preserved. Examples of food
preservations are bottling or canning, cooling, drying, freezing, heating,
pickling, salting, smoking, vacuum-packing, pasteurizing, and waxing.
We can enjoy the food for a longer time even the growing
season is over if the fruits and vegetables are preserved. It is useful for
the people in extreme weather where they cannot go out for hunting,
fishing or farming at certain period. They use preserved food as their
food supply.
Preserved food is easy to store as they become smaller when
dried. So the dried foods need smaller container for storing them.
Preserved food has a long shelf life. It is easier for the soldiers
to carry and take it as a food supply when they are in combat for a long
period.
Preservation also helps prevent wastage. During harvesting
there are plenty of fruits or grain in the market and make the price goes
down. By preserving them, it can avoid the food from destroy.

faster. There are seven types of simple machines such as
wedge, wheel and axle, lever, pulley, gear, inclined plane and
screw.
2. A gear can move objects forward or backward easily. Gears are
used to change the speed or directions of movement.
3. A pulley consists of a wheel and a rope. It is used to lift objects
to a higher place.
4. A wheel and axle is made up of a wheel connected to a rod
named an axle. It helps us to carry or move heavy objects
easily.
5. A screw is cylindrical and has a thread around it. It has a
pointed end. We use screws to fix two pieces of objects
together.
6. An inclined plane is a flat plane in a slanting position. It is used
to push heavy load up or down easily. It can lessen the effort
needed to move objects.
7. A lever has three parts such as effort, load and fulcrum. We use
a lever to carry or move over heavy objects easily.
8. A wedge has two inclined surfaces. It is sharp at one end. The
wedges are used to cut objects into two parts

12. A wheel and axle is made up of a wheel connected to a rod named an axle. It helps us to carry or move heavy objects easily.
13. A screw is cylindrical and has a thread around it. It has a pointed end. We use screws to fix two pieces of wood together.
14. An inclined plane is a flat plane in a slanting position. It is used to push heavy load up or down easily. It can lessen the effort needed to move objects.
15. A lever has three parts such as effort, load and fulcrum. We use lever to carry or over heavy objects easily.
16. A wedge has two inclined surface. It is sharp at one end. The wedges are used to cut objects into two parts.
Lesson 32 L32/WS1 8 The examples of wedges are an axe, a knife, a needle, a pair of scissors, a
chisel, a saw and a door wedge. 9 Some devices such as a hammer, a see-saw, pliers, a fishing rod and a nail
clipper are examples of levers. 10 A pulley used in a crane and on a flag post. 11 A gear found in a bicycle, a wrist watch, a drill and an egg beater. 12 An inclined plane principle is used in the staircase, a slide, driving up the hill
slope and pushing a box up the lorry. 13 The examples of tools using screws are bolt and nut, G-clamp, a spanner and a
water tap. 14 Wheel and axle used in the door knob, water tap, car steering and roller skates L32/WS 2 1 WEDGE - an axe, a knife, a needle, a pair of scissors, a door wedge 2 LEVER - a hammer, a see-saw, pliers, a fishing rod, a nail clipper 3 PULLEY - a crane and a flag post 4 GEAR - a bicycle, a wrist watch, a drill and an egg beater 5 INCLINED PLANE - a staircase, a slide pushing a box up the lorry 6 SCREW - bolt and nut, G-clamp, a spanner and a water tap 7 WHEEL AND AXLE - a door knob, water tap, car steering and roller skate L32/WS 3
