Diffusion particle theory lesson - fun lesson using sound effects, spices practical
This is a lesson on diffusion for younger students. The lesson begins with a literacy word unscramble activity that introduces keywords for the lesson. Students then carry out a practical where small amounts of 10 spices are placed around the classroom and they rate the smell from 1 to 10 weakest to strongest. Be careful as some spices contain traces of nuts - check for allergies at the start of the lesson. Discuss what makes a spice smell stronger using the word 'particle'. Answers may include that some particles are smaller or travel faster through the air. Higher ability groups may be introduced to the word 'vaporise' to explain why some substances have stronger smells. They then look at a large water trough (demo) that is filled with water and yellow food colouring. A drop of red food dye can be dropped into the tank to illustrate diffusion means. They then draw what is happening using coloured particle diagrams. You may play soundtracks from the film Finding Nemo or the song Who Let The Dogs Out. Please rate this resource and leave feedback.
