Provide the students with a copy of the Making Science Predictions – Worksheet to record their predictions of the experiment. Encourage the students to share their predictions with the rest of the class.
Take the class on a walk around the school so that each student can collect a green leaf for the experiment. On returning to the classroom, provide each student with a clear cup of fresh water.
Display slide 10 and walk through the experiment procedure with the students.
After placing the leaves into the cups, find a sunny area for the students to leave their experiments.
