Create Your Own Time Capsule
Source Institutions
In this archaeology-related activity, learners build their own time capsule and choose a storage location and a date to reopen it.
Mint Your Own Coin
Source Institutions
Coins are everyday objects which tell a lot about the people who use them.
Pollution in Our Watershed
Source Institutions
By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
Are Microbes Alive?
Source Institutions
In this activity (on pages 19-21 of the PDF) learners observe mold growing on potatoes. Preparation for this activity has to start a week before, to allow time for the mold to grow on the potatoes.
Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
Introduction to Ocean Zones
Source Institutions
In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Build a Coral Polyp
Source Institutions
In this activity, learners build one or more edible coral polyps and place them together to form a colony.
Reason for the Seasons
Source Institutions
In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.
Plant Piping
Source Institutions
Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.
Buried Bones
Source Institutions
In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet.
Fossil Dig Site
Source Institutions
In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.
Beach Zonation
Source Institutions
In this outdoor, ocean-side activity, learners investigate the distribution of organisms in the upper region of the intertidal zone.
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.
Sustainable Fishing
Source Institutions
In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.
Tree Trunk Diameter to Branch Height Relationship
Source Institutions
In this activity (located on page 2 of the PDF under GPS: Temperate Rain Forest Activity), learners will identify a group of deciduous trees to study.
Exploring the Universe: Imagining Life
Source Institutions
“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.
Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.
