Learning by exploring materials
As the video demonstrates we can help children to correct vocabulary misconceptions through carrying out a practical activity which relies on children continually returning to correct vocabulary definitions. In this case, we saw how exploring different materials’ properties helps to gain an understanding of the terms hard and strong.
To test a material’s hardness we may test to see how resistant it is to being scratched by running an iron nail along it.
To test a material’s strength we may see how much mass it can hold before it breaks.
This could be taken further to then consider which materials would be best for different tasks, based on their properties. This reasoning task makes the new concepts seem ‘fruitful’ as they are being used in a different context.
|Job/purpose||Suitable material||Reason based on properties|
|Kitchen countertops||Granite||Granite is hard and won’t scratch easily. A kitchen countertop will have people using knives to chop food so the top needs to be hard otherwise it would become scratched|
To embed the descriptions of scientific words further, we could also play some vocabulary games. For example, SPLAT! where a caller describes a word and the players have to be the quickest to ‘splat’ the matching word with their hand on a list in front of them.
Look through the chemistry topics in your scheme of learning and identify words which may cause misconceptions. Can you think of a vocabulary game which could help to clarify their meanings?
