In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

This is an activity that models the operation of a seismograph, a tool used to measure the size of earthquakes.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

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

“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

Learners examine the manufacturing process while they make picture frames from cereal boxes.

Learners construct and launch paper helicopters.

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.

To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
