Learners explore water's property of cohesion through two investigations.
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 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.
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.
In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.
In this water activity, learners explore how water drops behave on different surfaces.
Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of 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.
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.
Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
