In this nutrition/food science activity, learners conduct an experiment and record data to compare the amount of fat in different foods.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this activity, learners design a bungee jump for an egg using nylon stockings.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this activity (page 2 of PDF under GPS: Kinetic Sculpture Challenge Activity), learners will predict which objects have to overcome the most static friction to slide down a ramp.

In this activity, learners experiment with gear motion to understand how gears work to change the amount of force, speed, or direction of motion in machines.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

In this chemistry activity, learners explore whether matter is created or destroyed during a chemical reaction. They will compare the weight of various solutions before and after they are mixed.

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

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

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 (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

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.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
