2nd Class; Experimenting with seeds

We are experimenting with the conditions seeds need to grow. 1. The first pot has seeds, air but no water.

2. The second pot has seeds and water but no air. We boiled the water to remove the air then cooled it. Then we added a layer of water to prevent the seeds accessing air.

3. The third pot has seeds, air and water. Result: Only the pot with seeds, air and water grew.
