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.

Conversion immersion — it's measuring mania! A set of four activities teaches scholars to convert between customary and metric units. Resource covers unit conversions in length, temperature, weight/mass, and volume.

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

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...

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

Rings and golden nuggets contain the element gold, but how small can you break it down before it is no longer considered gold? A helpful presentation explains the basics about atoms, elements, and isotopes through a presentation.
