For example, ask the children to fill several plant pots with potting compost and plant seeds or cuttings. Water them and place transparent, colourless plastic bottles which you have cut in half over some of the pots to form mini greenhouses. Explain to the children why you are going to cover some of the pots and leave others uncovered. Otherwise treat all the pots the same: give them the same quantities of water and keep them in the same place, so that they get the same amount of light and heat. Every day observe what has happened to the plants and to the plastic bottles. As an extension activity the children could measure the temperature in the plastic bottles and in the room.
Afterwards talk with the children about which plants have grown the fastest and why that might be. Talk about how plants need warmth to grow and that they grow more rapidly in a warm atmosphere. The plastic bottles have a film of condensation on the inside which helps to keep the plants moist.
Springtime is fun – the days are warmer and the children feel happier. One idea is to set up a large spring picture on a wall or using powerpoint on a whiteboard, with a tree, pond and field. You can add frogspawn, tadpoles, frogs, blossom, spring flowers, etc as the season changes and as the children learn about them. Attach them with a tacky substance so that you can move them about and change the number of each of them on a weekly or daily basis.
Ask the children to count the number of butterflies, daffodils, tadpoles, lambs, ducks and caterpillars.
Each day or week change the numbers in the picture and ask them to count again.
On a windy day go outside with the children and watch streamers blowing. Ask the children whether they can see and feel the effects of the wind on their faces and clothes. Watch the trees and plants move in the wind.Continue reading →
Some pupils can find it difficult to grasp the concepts in the primary Science Programmes of Study. They want answers to questions such as: Why is the sky blue? How can the universe be infinite? Why don’t planes fall out of the sky?
