In this activity, learners use their hands as tools for indirect measurement.

In this math activity, learners create their own units of measurement by making noodle rulers. Learners practice estimating and measuring objects using the noodle rulers .

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 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 pretend there is a special store that lets you pay for toys by their height in pennies.

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 math lesson, learners apply the concepts of ratio and proportion to determine the length of the Statue of Liberty's torch-bearing arm.

Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.

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 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 pretend there is a special store that lets you pay for toys by their weight in pennies.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this math lesson, learners measure, predict and determine the frequency of an event as it relates to how close Whirlybirds land to a target.

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

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

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.

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