In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

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 build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Learners build simple catapults and use them to launch cotton balls.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

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

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

Learners develop an understanding of air pressure in two different activities.
