Leaves Beside the Pickup Counter

At a busy neighborhood parcel shop, workers wanted leafy plants beside the pickup counter. A nearby class offered to compare ways of caring for them. The students chose coleus plants, which have colorful leaves. A trait is a feature of a living thing. In this investigation, the students observed leaf position: whether a leaf stood upright or drooped downward.

Imani and Theo began with six young plants of the same kind. Each plant was about 10 centimeters tall and had eight upright leaves. They used matching pots with equal amounts of the same soil. The plants stayed together on one shelf, where they received similar light and warmth.

For seven days, an adult gave three plants 40 milliliters (mL) of water each morning. The other three received 10 mL each morning. The amount of water was the condition that changed. On the last day, just before watering, students counted drooping leaves. Each plant still had eight leaves. The graph shows their observations.
