Rocking Changes
Source Institutions
In this earth science activity, learners conduct a series of short experiments to explore how rocks change.
Eclipse: How can the little Moon hide the giant Sun?
Source Institutions
In this activity, learners explore how distance can affect the way we perceive the size of an object.
Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
Where Do We Choose to Live and Why?
Source Institutions
In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.
Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
Making a Field Journal
Source Institutions
In this activity, Christina Elson, an archaeologist from the American Museum of Natural History, guides learners as they investigate an "artifact" and record their observations in a field journal.
Create a Coral Reef
Source Institutions
Educator Amy O'Donnell from the American Museum of Natural History guides learners to create a diorama of a coral reef.
Air Pressure and Dent Pullers
Source Institutions
In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
Having a Gas with Water
Source Institutions
In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.
Sunblock Investigation
Source Institutions
In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.
Dinosaur Skull and Body Length Predictions
Source Institutions
In this activity (located on page 2 of PDF under GPS: Baby Dinosaurs Activity), learners will look for a relationship between skull size and body length among various dinosaurs.
The Crayon Rock Cycle
Source Institutions
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.
Amphipods: More than Mud
Source Institutions
In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.
Make Your Own Weather Station
Source Institutions
This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
A Hurricane's Storm Surge Affects our Estuaries
Source Institutions
In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.
An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
