In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.

In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
