In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity, learners make pretend snakes and use them to explore estimation and measurement. Learners roll out clay snakes and estimate and measure their lengths and diameters.

In this math activity, learners trace their hands and estimate the number of beans that can fit into their hand tracings. Then, learners glue the beans to the tracing to test out their estimations.

In this "Sid the Science Kid" activity, learners use their bodies to measure a room. Instead of inches or feet, how many kids does it take to measure the length of a room?

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.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this math lesson, learners use inchworm measuring tools to measure the lengths of several objects in the room.

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 math activity, learners build Peppy the dog the best trail and park for running around.

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

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

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

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

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

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, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.
