In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.

In this Cyberchase activity, have fun measuring volumes and enjoy a delicious shake.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

In this movement and measurement activity, learners jump as far as they can three times, and compare their longest jump to the longest jump of their friends, classmates and/or family members.

In this math lesson, learners practice measurement skills as they examine a soap bubble print. Learners follow a recipe to make a soap bubble solution.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

In this activity, learners build their your own seismograph with household materials to document shaking.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this experience, learners use the internet to research physical details about Chihuly's Fireworks of Glass "Tower" and "Ceiling" and consider the decisions Chihuly had to make as he was planning th

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.
