Free-Fall Bottles & Tubes
Source Institutions
In this physics activity, learners conduct two experiments to explore free-falling.
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).
Measure the Speed of a Water Leak
Source Institutions
In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.
A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
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.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Using Solar Energy
Source Institutions
In this activity, learners discover how solar energy can be used to heat water.
Aesop's Arithmetic
Source Institutions
In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level
Cool It!
Source Institutions
Learners make a refrigerator that works without electricity. The pot-in-pot refrigerator works by evaporation: a layer of sand is placed between two terra cotta pots and thoroughly soaked with water.
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.
Water Exploration Station
Source Institutions
In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.
Sinking Water
Source Institutions
In this experiment, learners float colored ice cubes in hot and cold water.
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?
Oh Buoy!
Source Institutions
Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.
Let's Look at Water & the Scientific Method
Source Institutions
This activity has learners observe water and compare it to other liquids.
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.
Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
Be A Pasta Food Scientist
Source Institutions
In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.
The Incredible Journey
Source Institutions
In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.
