Assessment
There is no assessment for this activity since students are setting up an experiment to learn from later on.
Tips
- If many of your students seem convinced that plants will not grow without soil nutrients, you may want to rehydrate a few gel crystals with water only to see if the radish seeds will germinate and start to grow (they should!).
- Allow students to take pictures of what they are putting into their test tubes as a reference for later on after plant growth.
