Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
Sinking Water
Source Institutions
In this experiment, learners float colored ice cubes in hot and cold water.
Build a Borneo Glider
Source Institutions
In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So
Swing That Pendulum
Source Institutions
In this full inquiry activity (located on page 3 of the PDF under GPS: Kinetic Sculpture Challenge Activity), groups of learners will make predictions about which feature of a pendulum (mass, length,
If Hot Air Rises, Why is it Cold in the Mountains?
Source Institutions
This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside
Below the Surface: Surface Tension II
Source Institutions
In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?
Layers of Liquids
Source Institutions
Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.
Temperature Tactics
Source Institutions
In this activity, learners explore the devices used over time to measure changes in temperature.
Can You Copperplate?
Source Institutions
In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.
Convection Demonstration
Source Institutions
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.
That's the Way the Ball Bounces: Level 2
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.
Composites
Source Institutions
In this activity, learners explore how composites work by creating and testing their own composite for an imaginary company.
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
What is a “Convection Cell”?
Source Institutions
In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Volcanic Material Catapult Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
What is in the Water?
Source Institutions
In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.
Physical Change
Source Institutions
In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.
How Many Pennies?
Source Institutions
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
