In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.

In this craft activity, learners will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.

In this math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.

In this activity, learners find as many combinations of a hundred as they can using various puzzle pieces from a hundred square grid paper.

In this activity, learners explore the great pump in their chests--the human heart!

In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.

In this activity, learners play a game that helps young mathematicians recognize how the numbers 0 through 5 are related. Learners toss five pompoms into circle made out of string on the floor.

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.

In this game, learners strategize to win the most cards by building number equations. Learners practice operations (addition, subtraction, multiplication, and division) to construct their equations.

In this math game, learners toss plastic cups to land just right and collect points to win.

In this math activity, learners make and explore patterns using the letters in their names, a grid, and some colors.

In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.

In this math game (Page 9 of the Are You Game? PDF), learners determine what makes a spinner fair or unfair. Learners first play a round with a pre-made spinner that isn't very fair.
