Many people get water from a source deep underground, called groundwater.

In this physics activity, learners will explore buoyancy.

In this activity, learners will write a secret message that only their friends will be able to read.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners use found natural materials to create a water haven for bees and other insects.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
