Simple experiments for KS2 scientists

Children learn about life processes common to humans, animals and plants (such as nutrition, movement, growth and reproduction); about the role of the skeleton and muscles to support and protect us and help us to move; that the heart acts as a pump to circulate the blood around the body.

They will also discover microorganisms, learning that these are tiny living organisms that can be beneficial (for example, in the breakdown of waste) or harmful (for example, in causing disease or food to go mouldy).

Your child will be grouping and classifying materials, exploring their everyday uses and the effects of processes (such as heating, dissolving, melting, freezing, and evaporating). They will also discover how to separate solid particles by sieving.

In this strand of science, your child will be constructing circuits and understanding how they work. They will also explore attraction and repulsion between magnets and magnetic materials, and gravity.

Light and sound will be investigated. Your child will learn that light cannot pass through some materials and that sounds are really vibrations that require a medium (for example, metal, wood, glass, air) through which to travel to the ear.

Finally, children will learn about the sun, earth and moon - how day and night are related to the spin of the earth, that the earth orbits the sun once each year, and that the moon takes approximately 28 days to orbit the earth.

• Look up information about the different food types required for a balanced diet. Why are they needed? Plan a balanced meal together.
   
• Look at books together on the life cycle stages and talk about them.
   
• Plant mustard seeds in soil and place them in different environments - dark, light, wet and dry. After a determined period, look at them and note the differences. Draw the differences or take photographs and get books to find out some information about what causes these variations.
   
• Show your child how to change a plug.
   
• Try simple experiments with your child. Make observations such as, “When I put a seed in a wet environment it grows” or “If I place a round object on a flat surface it rolls”, or ask questions such as, “What happens if I put sugar in a full cup of water at room temperature?” “What will happen if I continue to add sugar?”
   
• Make them aware of the contributions of different nations to science.
