In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

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.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
