In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

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

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

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

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity, learners are challenged to calculate their own weight on various planets using a scale and calculator. Older learners may be challenged to do so without using calculators.

Learners build a simple hovercraft using air from a balloon to levitate a craft made from a compact disc (CD).

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

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

Learners construct a rocket from a balloon propelled along a guide string.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Learners explore the concepts of equilibrium and center of mass by seeing how non-symmetrical objects balance.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

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

Learners construct and launch paper helicopters.

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.
