Pupils learn everything from how to take scientific measurements, to accuracy/precision, to density and a plethora of topics from a presentation on the metric system.

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

How do you properly illustrate the extreme size difference between two planets—Earth and Jupiter? With the help of jellybeans, of course! Create a scale model of Jupiter's mass compared to Earth using a fishbowl, 1,400 beans, and a...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Scientists discovered the first exoplanet in 1995 and by early 2018, they confirmed the existence of more than 3,700—that's a lot of data! As part of the PBS 9-12 Space series, scholars interpret data about exoplanets. They compare...

Students see the difference between weight and mass when they examine the method of measuring each of them.

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Students decide what body measurements they need to make garments such as a pair of pants. They make a list, and work with a partner to take and record those measurements in centimeters. They discuss the use of centimeters.

High schoolers are able to analyze gravity as an universal force. They are able to demonstrate ways that simple machines can change force. Students are able to determine how the force of friction retards motion. They are able to...

Fifth graders study air pressure and learn how it can change the weather. In this air pressure lesson, 5th graders study the given diagrams and complete the experiments to learn how air pressure can change the weather. Students read...
