Surface Tension Icebreaker
Source Institutions
This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.
Defining Density
Source Institutions
In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.
Changing the Density of an Object: Changing Shape
Source Institutions
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
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.
Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.
Enhanced Water Taste Test
Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Ice Melt
Source Institutions
In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.
Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.
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.
Be a Plumber
Source Institutions
In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.
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.
Cool Trees
Source Institutions
This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.
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.
Surface Tension
Source Institutions
In this activity exploring liquid dynamics, learners design and build a clay channel in a tray of water and then see what happens when food coloring and liquid soap are added to the mix.
