This is an activity about the tides. Learners discover how the Moon's gravitational pull causes the level of the ocean to rise and fall twice a day along most coastlines. Six children represent the oceans, solid Earth, Moon, and Sun and move their... (View More)

This is a set of three activities about the distance to Saturn. Learners will use simple props to create a playground model for size and distance for the Sun, Earth, and Saturn - then walk on their scale model to Saturn. Includes a glossary,... (View More)

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen... (View More)

In this two-part activity, learners compare how soil forms on Earth and the Moon. They examine different soil samples and compare them to lunar "soil" simulant. They explore how water, wind, and impactors help to make soil. This activity is part of... (View More)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star, as they learned in the "Elements and You" activity. They are introduced to the life cycle of a star and to... (View More)

This is an activity about seasons. Learners begin by brainstorming a list of activities and events that occur in each season. Next, learners perform an experiment by comparing the temperature on thermometers left under a lamp for different lengths... (View More)

This lesson uses a simple discrepant event to demonstrate the underlying cause for early miscalculation of the size of the Milky Way galaxy. By standardizing the Cepheid period-luminosity relationship without recognizing there were two types of... (View More)

In this lesson, students explore how eclipses happen and why Einstein needed a total eclipse to image stars near the Sun in order to demonstrate how the Sun's mass bends the light from a far away star. Using a foam ball and a lamp, learners create a... (View More)

This resource describes the physics behind the formation of clouds, and provides a demonstration of those principles using a beaker, ice, a match, hot water, and a laser pointer. This resource is from PUMAS - Practical Uses of Math and Science - a... (View More)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)
