In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

In this math lesson, learners explore and investigate measurement using standard and non-standard units.

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

In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

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 activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

The demonstration/experiment provides quick proof that air has mass.

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

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 use simple items to construct a device for indicating air pressure changes.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.

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 explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

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