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 activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

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

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

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.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
