A group of learners models the Sun shining on the Earth. By rotating the Earth, they demonstrate how the Sun only shines on a portion of the Earth at a time.

Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.

In this online game, learners run an outer space drink stand and thirsty alien customers are on the way.

Learners draw comic-style pictures to show the water cycle. From a starting picture, one learner draws what happens to the water in the next panel, then passes the comic strip to another learner.

Learners classify a variety of objects by their characteristics. They then design an experiment to determine which objects float or sink in water and add this characteristic to their classification.

Learners draw and cut out shapes of organs from construction paper. Then they attach these organs to the body of one learner to make a life-sized map of all the internal organs.

In this online game, learners attempt to send a rocket ship to various targets. Learners can adjust the angle and thrust of the rocket before it is launched.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.
