In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space! Learners will...

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object. They will see that no matter what the object, these...

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel. This is one of four...

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height. This activity is a fun way for learners to...

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a...

In this activity, learners work in teams to simulate the process used by Global Positioning Systems (GPS) to determine the location of a fallen meteorite in Antarctica. Learners will examine how...

This lesson plan provides learners with two activities to explore the connections between events in their lives and the seasons of the year. Learners follow lists of instructions and create...

In this activity, learners discover that some things only stand up while they are spinning. To explore this phenomenon, learners build tops from household items such as CD's, paper plates,...
