Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity, learners discover that some things only stand up while they are spinning.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

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

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

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

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.

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 trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

In this electrochemistry activity, learners will explore two examples of electroplating.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.
