Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

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

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

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

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

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
