Perspectives: Powers of 10
Source Institutions
In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

Excavating and Mapping Under Water
Source Institutions
In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

Where Are the Distant Worlds? Star Maps
Source Institutions
This fun hands-on astronomy activity lets learners use star maps (included) to find constellations and to identify stars with extrasolar planets (Northern Hemisphere only, naked eye).

Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

To Taste or Not to Taste
Source Institutions
In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

Tiny Tubes
Source Institutions
In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

Recrystallization Test
Source Institutions
In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

Electrical Fleas
Source Institutions
In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.

Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

Right Foot/Left Foot
Source Institutions
In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?

Matter on the Move
Source Institutions
Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

Chemical Footprint—Family Activity
Source Institutions
In this multi-part activity learners examine non-point water pollution.

DNA Extraction
Source Institutions
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

Where Will It Go?
Source Institutions
In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

Identifying Erosion
Source Institutions
In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

Join the Dinosaur Age
Source Institutions
In this activity, learners rotate through several learning and play stations to explore dinosaurs and paleontologists.

Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

The Shape of Floatation
Source Institutions
In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.
I Spy Shapes
Source Institutions
The learner will ask yes-no questions to identify a secret shape (similar to Twenty Questions). Build understanding of shapes and logic skills with this game for all ages.
