Using indirect observational methods, learners distinguish between charged and uncharged objects.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

In this activity, learners explore the relationship between electric charges and magnetic fields.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.
