Gravity-Defying Water
Source Institutions
In this activity, learners explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.
To Dye For
Source Institutions
Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.
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.
Miscibility
Source Institutions
Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.
Outrageous Ooze: Is It a Liquid or a Solid?
Source Institutions
This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.
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.
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.
Making Waves
Source Institutions
Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.
Water Drop Exploration
Source Institutions
In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.
Chromatography Observations
Source Institutions
In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.
School of Fish
Source Institutions
In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.
Bridge the Gap
Source Institutions
Learners work in groups to construct bridges using stale marshmallows and toothpicks.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
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.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
Pepper Scatter
Source Institutions
In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract
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?
