Wiggly Water
Source Institutions
This is a simple and fun activity for learners to explore water and colors.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Changing the Density of a Liquid: Adding Salt
Source Institutions
Learners see that a carrot slice sinks in fresh water and floats in saltwater.
Soap: Sometimes oil and water do mix!
Source Institutions
In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.
Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
Colors Collide or Combine
Source Institutions
Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Chromatography
Source Institutions
In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.
Investigating Density Currents
Source Institutions
In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).
Surface Tension Icebreaker
Source Institutions
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Cohesion Coin
Source Institutions
In this activity about the property of water (page 6 of the PDF), learners use a coin to demonstrate cohesion between water molecules, exploring the molecular forces that allow water molecules to "
Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
What's So Special about Water: Absorption
Source Institutions
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.
