In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this activity, learners use measurement concepts to make models of what their body parts might look like if they were a snake or a chameleon.

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

Learners construct and use a "real" 3D coordinate system out of balsa wood and foam core. They will then be able to locate coordinates in space.

In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

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 use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.
