In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

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 will explore how a hydrometer works by building a working model and conducting experiments.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

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