Comparing the Density of an Object to the Density of Water
Source Institutions
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
Big and Little Cups
Source Institutions
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

Water: A Basic Ingredient
Source Institutions
In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

What's So Special about Water: Surface Tension
Source Institutions
In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.
Making Rivers
Source Institutions
In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Float or Sink?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

Forces at the Nanoscale: Nano Properties of Everyday Plants
Source Institutions
This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Racing M&M Colors
Source Institutions
Learners design their own experiment to determine which M&M color dissolves the fastest in water.

Collect Invertebrates to Determine Water Quality
Source Institutions
This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
Without An Ark: The Effects of Storms and Floods
Source Institutions
April showers bring May flowers, but what do coastal storms bring?

Look-alike Liquids
Source Institutions
Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

Temperature Affects the Solubility of Gases
Source Institutions
In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

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

Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

The Dead Zone: A Marine Horror Story
Source Institutions
In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

Traveling Through Different Liquids
Source Institutions
Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

Charge Challenge
Source Institutions
In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

Heating and Cooling of the Earth's Surface
Source Institutions
Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.
