Do Your Own Dig
Source Institutions
In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.
Relative Speed of Dinosaurs
Source Institutions
In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
Map Your World
Source Institutions
In this activity, learners map their world by drawing a plan of their bedroom.
What's the Angle?
Source Institutions
This activity helps learners understand how the angle of the Sun affects temperatures around the globe.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
Slowing the Flow
Source Institutions
In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.
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.
