So while first graders know about plant parts and their jobs, they need to gather evidence to support their thinking. Students have seen the importance of flowers and fruit, and now they're moving on to the specific jobs that stems and leaves do!
We placed two plants in a box, and watched them for over a week. Both boxes had lids, but one box had a hole in it and the other did not.
First graders concluded that plants definitely need light and air to grow, but that the leaves and stem specifically respond to where the source of light is coming from. They work together to hold up the plant and help the plant collect light to make its own food. Awesome job first graders!

- The plant that was in a box with a lid and no holes DIED.
- The plant that was in a box with a lid and a hold SURVIVED...and grew TOWARDS the hole!
