Science Year 5 - Unit 1 Microorganisms

Learn about microorganisms, the study of microbiology and why these tiny creatures are so important to living things with this fun, interactive activity. Microorganisms are important to life on Earth, acting as decomposers in various ecosystems and playing a vital role in the nitrogen cycle. Types of microorganisms include bacteria, fungi, types of algae and plankton.

Microorganisms make their home on food, plants, humans and lots of other living things. Look hard and spot places where you think they might be at work. Learn about bacteria that live in decaying leaves, diseases, moldy fruit, yeast in breads, bacteria in yoghurt, salmonella in uncooked food and more. Sort the different types of microorganisms and enjoy this fun science game for kids.

There are tiny living things that can only be seen through a microscope, these are called microorganisms. In the above video, you can see different types of microorganisms, there are bacteria, protozoa, fungi and virus. Just like other living thins, microorganisms also undergo life processes. They breather, move and grow.

Science Year 5 - Unit 2 Survival of the Species

Mammoths and dinosaurs are examples of animals that no longer exist. Is it because of their gigantic size? Elephants look similar to mammoths. Why are they still surviving? Rafflesia is an example of a plant species found in Malaysia that is facing extinction. Why? How do animals and plants ensure the survival of their species?

1. Animals take care of their eggs and young to ensure the survival of their species.
2. Plants disperse seeds and fruits to ensure survival of their species.
3. Shortage of food can cause extinction of species. 





Animals and plants need food to survive. One animal species is a source of food to another. For example, eagles eat snakes. If snakes do not survive, there will be shortage at food for eagles. The eagles may become extinct.



Plants cannot move freely. Therefore, their seeds and fruits need to be dispersed from the parent plants. They are dispersed by wind, animal, water or explosive mechanism. Dispersal of seeds and fruits help to scatter them far away from the parent plants. This helps to ensure the survival of plant species.



Shortage of food can cause extinction of species, mammoths and dinosaurs are examples of animals that no longer exist. 

Science Year 5 - Unit 3 Food Chain and Food Web

There are frogs, butterflies, snakes, caterpillars and birds living in this habitat. There are various types of plants too. Some animals eat plants or other animals for food, What about plants? 

Animals can be classified into three categories according to the food they eat.
  1. Animals eat plants are herbivores.
  2. Animals eat the other animals are carnivores.
  3. Animals eat plants and the other animals are omnivores.
Plants use the energy from the Sun to make their own food. They are called producers. Plants provide energy to herbivores, carnivores and omnivores, this relationship is called a food chain. The herbivores, carnivores and omnivores are called consumers because they get their food by eating other animals or plants.


(P = producer, H = herbivore, C1 = carnivore order-1, C2 = carnivore order-2)

The relationship between organisms in food chains looks very simple, but in reality it is more complex. When two or more food chains linked together, this relationship is called a food web.





Science Year 5 - Unit 4 Energy

Energy is important to our lives. We use energy to do work. Energy lights up our cities. Energy moves our cars, trains and enables us to watch televisions. What would happen if there is no energy?

Living things carry out life processess. Energy is needed to carry out these processes. Energy is also needed by non-living things. The energy is used to make them usable.

The Sun gives us heat and light energy. Plants use sunlight to make food. Humans and animals get energy form the food they eat. Their sources of food include plants and other animals.

Fuels such as coal, petroleum and natural gas are sources of energy too. These fuels are formed from dead plants and animals that lived millions of years ago.




Energy is found in different forms. The batteries in a toy car produce electrical energy to move it. Objects that move have kinetic energy. A burning candle gives off light energy and heat energy. A strectched rubber band in a catapult has potential energuy.

Energy can be transformed form one form to another. Switching on the light transforms electrical energy into light energy. A burning candle transforms chemical energy into light energy and heat energy. Solar powered signal light uses sunlight as the source of energy. The solar energy is transformed into electrical energy and then into light energy.

The energy we use everyday comes from various resources. These resources are divided into renewable energy and non-renewable energy.

Science Year 5 - Unit 5 Electricity

We depend on electricity in our daily lives. Electricity has made our lives easier and more comfortable. There are many sources of electricity. Many appliances in our homes and schools use electricity. However. we must be very careful when using electrical appliances. Why?

Some electrical appliances use dry cells to make them work. Dry cells produce electricity. There are also other sources of electricity such as accumulator, dynamo and solar cell. They are examples of batteries.

Accumulators are used in vehicles such as motorcycles, cars and lorries. Dynamos generate electricity. They are used to light up the bulb of bicycle. Satellites get their electricity from solar cells. Solar cells transform light energy into electricity. We can also get electricity from hydroelectric power sation. 

An electrical circuit is made up of a power source, wires and other components such as a bulb and a switch. The dry cell is a source of electrical energy for the circuit. A switch is used to break or complete a circuit. The wire allows electricity to flow through the circuit. The bulb lights up because electricity flows through it. 

Electricity is useful in our everyday life. Electrical appliances need proper handling because they can cause injury if they are not used properly. Mishandling of electrical appliances can cause. There are safety precautions that must be taken when using electrical appliances.
  • Do not touch switches with wet hands.
  • Do not connect too many electrical appliances to one power point.
  • Do not repair electrical appliances by yourself.
  • Do not use electrical appliances that are faulty.
