Meteoroids and the Craters They Make
Source Institutions
In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.
Soup Can Derby
Source Institutions
In this activity (on page 2 of PDF under GPS: Roller Coaster Design Activity), learners will use food cans of many different properties (sizes, shapes, and weights) and set two cans on their sides at
Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
Lagging Sound
Source Institutions
In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.
Twirling in the Breeze
Source Institutions
In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.
Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
Relative Speed of Dinosaurs
Source Institutions
In this activity, learners interpret three trackways and use measurements and a formula to infer the relative speed of dinosaurs.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Rubber Band Racers
Source Institutions
In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.
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.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
Marshmallow Puff Tube
Source Institutions
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.
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.
