This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

In this activity, learners investigate static electricity using everyday objects at four different stations.

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
