EXPERIMENT 1

 “Plants have to have soil !” says Riya

Is this true? Can a seed germinate without any soil?

We are learning about the germination process.
Hypothesis: (Students think) A seed will not grow if it has water and sunlight, but no soil.

We are doing an experiment to help us understand and observe the growth of a seed.

1.   First we wet a tissue then carefully placed 3 seeds in the tissue and folded it over.
2.   Next we put it in a sealable bag and placed it in the sun on our shelf.
3.   We will add a teaspoon of water when the tissue dries out.

4.   Each day we will make observational notes and diagrams of the germinating seeds.



8th June
After a lot of water, waiting, observation we found out that SEEDS CAN germinate without soil!
Our bag experiment wasn't as clear to observe as we would have liked so we had a big example in a jar! Take a look!
