PVC Water Squirter
Source Institutions
In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.
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.
Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.
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.
What's So Special about Water: Solubility and Density
Source Institutions
In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.
Find Out How Plants Use Water
Source Institutions
In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.
Free-Fall Bottles & Tubes
Source Institutions
In this physics activity, learners conduct two experiments to explore free-falling.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Submersibles and Marshmallows
Source Institutions
In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.
Science at the Waterpark!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.
Window Under Water
Source Institutions
Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.
Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
Plant Piping
Source Institutions
Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.
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.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.
Crocodiles
Source Institutions
Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.
Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.
School of Fish
Source Institutions
In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.
Wetland Filter Model
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.
