Airfoils
Source Institutions
In this experiment, learners discover how an airfoil creates lift. Learners use simple materials to build an airfoil and test it at different angles to investigate Bernoulli's principle.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
Reflective Solar Cooker
Source Institutions
In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
Aerial Imagery
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
Keep Out!
Source Institutions
In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.
Kick Stick Challenge
Source Institutions
In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across
Sky Floater Challenge
Source Institutions
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.
Grab and Go
Source Institutions
In this engineering activity, learners design and build a mechanical arm to lift a small item.
Soccer Kicks
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.
Series and Parallel Circuits
Source Institutions
In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
Building an Army
Source Institutions
In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.
Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
No-Slip Grip
Source Institutions
In this physical sciences activity, learners explore friction. Learners investigate the factors that affect the force required to move an object.
