Student groups are provided with a generic car base on which to design a device/enclosure to protect an egg on or in the car as it rolls down a ramp at increasing slopes. During this in-depth physics/science/technology activity, student teams design, build and test their creations to meet the design challenge, and are expected to perform basic mathematical calculations using collected data, including a summative cost to benefit ratio.

Through this activity, students will be able to explore the role of mass distribution as cylinders roll down an incline. Students will roll two cylinders filled with the same mass, but distributed differentlly. Students will predict which one reaches the bottom faster. Using easily accessible materials, this activity can be conducted in the classroom.

Students use a compass and a permanent magnet to trace the magnetic field lines produced by the magnet. By positioning the compass in enough spots around the magnet, the overall magnet field will be evident from the collection of arrows representing the direction of the compass needle. In activities 3 and 4 of this unit, students will use this information to design a way to solve the grand challenge of separating metal for a recycling company.

This is an activity about observing and mapping sunspots by direct solar observation. Learners will use a small telescope, binoculars, or a Sunspotter to create a projected image of the Sun and trace the position of any observed sunspots on a piece of paper. Additionally, learners will mark the direction of the Sun image’s motion. This is Activity 2 of the Space Weather Forecast curriculum.
