Quick Questions: Create a Survey
Source Institutions
In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? What’s the most common? the least common?

Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

Atoms and Matter (3-6)
Source Institutions
In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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.

Ball Bounce Experiment
Source Institutions
In this activity, learners investigate the properties of different types of balls.

Take a Hike!: A Family Forest Walk
Source Institutions
In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.
Pencil Drop
Source Institutions
In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.

Heavyweight Champion: Jupiter
Source Institutions
In this activity, learners confront their perceptions of gravity in the solar system.

Flocking for Food
Source Institutions
In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

Physics in a Glass: Reversing Arrows
Source Institutions
In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

Surface Area and Soda Geysers
Source Institutions
This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

Space Stations: Bones of Contention
Source Institutions
In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

Setting the Scene
Source Institutions
In this activity (on page 2), pairs of learners create an imaginary crime scene. One person leaves the room while the other person moves a few things around.

I Like to Move-It
Source Institutions
This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

Solar Structures
Source Institutions
In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

Funny Putty
Source Institutions
In this chemistry activity (page 1 of PDF SciGirls Activity: Milk Carton Boat), learners will create a blob of stretchable funny putty out of a water, borax, and glue mixture.

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.
