In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this activity, learners investigate and compare the rate of drying in different conditions.

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
