Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
Keep-a-Cube
Source Institutions
In this activity, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.
COSI's Flubber Recipe
Source Institutions
Everybody loves messy science, and Flubber is a favorite of both COSI employees and guests!
COSI's Bubble Recipe
Source Institutions
Everybody loves bubbles, and this is the best bubble recipe ever!
Pepper Scatter
Source Institutions
In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract
Music and Sound
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.
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,
Chair Lift Challenge
Source Institutions
In this activity, learners explore the unique challenges in transportation engineering, such as devising a method for skiers or hikers to get to the top of a mountain.
Whodunit?
Source Institutions
In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.
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?
Temperature Tactics
Source Institutions
In this activity, learners explore the devices used over time to measure changes in temperature.
Oh Buoy!
Source Institutions
Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.
Balloon in a Bottle
Source Institutions
In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.
Puff Mobile
Source Institutions
In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.
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.
Modeling Tidal Action
Source Institutions
In this activity (Lesson 1), learners work in groups to create tide simulations.
Three Colors of Light
Source Institutions
Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.
The Pressure's On
Source Institutions
In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!
