Can you think of any new challenges you might face if you tried these experiments in the real world?

Activity Prep

Print Prep

In this lesson, students investigate how different plants grow best under very different conditions, ranging from deserts to tropical rainforests. In the activity, Puzzling Plants, students plan and conduct virtual experiments in order to determine how much water and sunlight a set of mystery plants need to grow and stay healthy.

Preview activity
Number of students:

I have a Mystery Pack

Build-Your-Own Experiment printout 1 per student
Sunlight Experiment worksheet 1 per student
Water Experiment worksheet 1 per student
Crayons
We suggest providing green, yellow, blue, red, and brown.
Details
4 crayons per student
Glue Sticks
1 glue stick per student
Scissors

Prep Instructions

We suggest students work in pairs to share ideas. Homeschool students can work on their own.

Experiment with Real Plants

This activity walks students through virtual experiments to help reinforce the concept that an experiment should only change one part (variable), but keep all the other parts the same (controls).

We think it’s best to follow-up these learnings with a hands-on experiment that uses real plants! If you have radish plants leftover from the lesson “Could a plant survive without light?”, you can guide your students to plan and conduct a few classroom experiments.
