What's in the petri dish?
An idea to introduce Magnification- In each group, 3 petri dishes containing the following are sealed with tape so the petri dishes can be passed around the group with no spillages: 1. Sand 2. Soil 3. 1 x pipecleaner cut into small pieces Using the table on the worksheet, write down what can be seen and then looking through a magnifying glass/ hand lens- describe what can be seen. Takes about 5-10 minutes including asking each group their observations leading into the concept of magnification.
