Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.
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.
Arctic Story Puzzles
Source Institutions
This activity has three story puzzles learners can solve to learn about life in the Arctic.
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.
Locating a Point
Source Institutions
In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica.
Stargazing
Source Institutions
In this nighttime, outdoor activity, learners keep a record of what they see in the sky by drawing constellations, the Moon, and making note of the weather and conditions each day.
Smaller Than You Think
Source Institutions
Learners compare a life-size drawing of a Tyrannosaurus rex head and a full-size Sinornithosaurus body to understand that dinosaurs varied in size.
What's the Angle?
Source Institutions
This activity helps learners understand how the angle of the Sun affects temperatures around the globe.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.
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.
Making Map Projections
Source Institutions
In this activity about cartography, learners work in teams to create two different map projections: a planar (or polar) and a cylindrical (or Mercator) projection.
Build the Big Dipper
Source Institutions
Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.
Moon Watch Flip Book!
Source Institutions
In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.
Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.
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.
