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.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
Sinking Water
Source Institutions
In this experiment, learners float colored ice cubes in hot and cold water.
Tie Dye Secret Messages
Source Institutions
In this activity, learners will write a secret message that only their friends will be able to read.
Below the Surface: Surface Tension II
Source Institutions
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?
Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.
Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
Eyedropper Hydrometer: Buoy your understanding of density
Source Institutions
Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.
Balloon in a Flask
Source Institutions
Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.
Filtration Investigation
Source Institutions
In this activity, learners explore how engineering has developed various means to remove impurities from water.
Let's Look at Water & the Scientific Method
Source Institutions
This activity has learners observe water and compare it to other liquids.
Meltdown
Source Institutions
In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.
Soapy Boat
Source Institutions
Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
We all Scream for Ice Cream
Source Institutions
In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
TerrAqua Investigation Column: What is the Land-Water Connection?
Source Institutions
In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.
A Spray Spree
Source Institutions
In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.
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.
Can Crushers
Source Institutions
In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.
