In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

This lab activity has learners create a pendulum with a one-second period.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners are challenged to design and construct a windmill to harness the power of wind.

The goal of this activity is to design, build and test a house or toy for an animal.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.

In this activity, learners are challenged to design and build a system of gears and kinematics to create a hand-stamping machine.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this activity, learners explore watercraft engineering and sailing.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

Learners can program a compass to draw a circle by itself using a Pico Cricket, some Legos, and lots of tape! Pico Cricket is required.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.
