Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Mass of the Earth
Source Institutions
In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

Dripping Wet or Dry as a Bone?
Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Lungometer
Source Institutions
In this environmental health activity, learners investigate their own vital lung capacities.

Digit's Cyber-Dough
Source Institutions
In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

Malformed Frogs
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Malformed Frogs) is a full inquiry investigation into using indicator species to assess the health of an environment.

Number Sense and Computation: Soak It Up
Source Institutions
In this math lesson, learners compare products to determine the best product.
The Blue Crab's Chesapeake Journey
Source Institutions
In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.

Chances Are: OH NO! Look Out Below for a UFO
Source Institutions
In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

Arctic Sea Ice
Source Institutions
In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.
