Last lesson we learned how a habitat gives living things everything they need. But what happens when that habitat changes? Today we find out — and we plant our own investigation to watch it happen.

Let's connect to what we already know.

Habitats can change in two main ways. Both can affect whether living things survive.

Watch how one change — a drought — ripples through a whole habitat.

Now we become the scientists. We'll grow real seeds and change one condition to see how it affects growth.

Let's plan it together using our three variable jobs:

In your groups, set up your seed pots carefully. This investigation runs over the next week, so accuracy now matters.

Before we pack up…
