In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

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

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this activity, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
