Sure, you may be able to build a better mousetrap, but what about a gum dispenser? In a fun engineering challenge, teams must design and build a working interactive gumball machine with specific constraints and criteria.

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages children in...

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

Twisting and turning through the sky, roller coasters are popular attractions at amusement parks around the world, but how exactly do they work? Explore the physics behind these thrilling rides with an engineering design activity....

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts of velocity,...

After reading a brief overview of automobile history and introduction to energy and motion, automotive engineering teams plan, construct, test, and evaluate a rubber-band-powered car. This manipulative experience can enrich understanding...

Using a cut-out template of a whirligig, emerging engineers experiment with flight behavior. After you teach them the concepts of force, air resistance, and lift, they discuss what variables on the whirligigs might be changed in order to...

Three, two, one, blast off to a better understanding of force and motion with this exciting science activity! Beginning with a discussion about rockets and gravity, young scientists go on to complete a series of worksheets about net...

Get kids' heads spinning by challenging them to design a top that will rotate for a minimum of 10 seconds without leaving a 30-cm circle. Groups of learners collaborate through a planning stage, testing stage, and evaluation stage. Some...

Students examine gravity, mass, and friction. In this speed and motion lesson, students investigate how straight line motion is impacted by gravity, mass, and fiction as they participate in a hands-on activity.
