Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
Underwater ROV
Source Institutions
In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).
Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
Physics in the Sky: Physics on a Plane
Source Institutions
On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.
Engineer a Dam
Source Institutions
In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.
Up, Up and Away with Bottles
Source Institutions
In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.
Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.
Wind Tube
Source Institutions
In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.
The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.
Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.
Out of Sight: Remote Vehicle Activity
Source Institutions
In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.
Balloon Staging
Source Institutions
In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
