In this activity, learners discover what buoyancy is and determine the characteristics that make an object buoyant. Learners design, build, test, and evaluate boats made from a variety of materials.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.

In this activity about heart health (on page 34 of the PDF), learners measure their own blood pressure using an electronic blood pressure monitor with a self-inflating cuff (included in cost of materi

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with

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).

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

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

In this activity, learners build a model roller coaster to help the Mummy entertain the Atom's Family monsters. Learners assemble the roller coaster between two chairs using vinyl ceiling molding.

In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

Learners follow the template to build and fly a paper helicopter.
