The first slide contains a scenario looking at the fact that hydrangeas have different colored flowers depending on the pH of the soil they are grown in. It can be used as a starter and students give their responses. The students can then test soil from both gardens. See other resource 'soil testing' for a worksheet to accompany this proactical.
