In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

This lab activity has learners create a pendulum with a one-second period.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

In this physics activity, learners conduct two experiments to explore free-falling.

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

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography").

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

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.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.
