In this inquiry investigation, students study the motion and positions of the Earth and how they affect the path of sunlight we get in different places. They discover that the Earth must be curved to account for the different lengths of shadows at... (View More)

In this activity, students become familiar with the orientation of shadows, their size in relation to the object casting them, and how the alignment of the Sun, the object, and the shadow tells us much about how shadows work. Supplies needed for... (View More)

Keywords: Angle

In this inquiry investigation, students discover how a given amount of light changes in intensity when the area it shines on changes, and that change in light and heat occurs when the Earth is tilted towards or away from the Sun. Supplies required... (View More)

In this inquiry investigation, students conclude that the motion of the Earth is linked to the changes we observe such as the length of the day. Students learn about the reason behind the Earth's time zones. An optional water clock and sand clock... (View More)

In this inquiry investigation, students will learn about how light travels by using mirrors, prisms, and shadow makers. Supplies for this investigation include mirrors, prisms, objects of differing transparency, garden hose or spray bottle,... (View More)

This inquiry activity supports student understanding of the cause of light, heat and shadow, how to measure the passage of time, and how to use rules and other measuring tools. Students make observations using shadows, a meter stick, and a homemade... (View More)

Learners will use water balloons to demonstrate meteorite impacts, use geography to assess various terrains for meteorite recovery, attempt to recover simulated meteorite fragments, make experimental predictions, graph the results, and draw... (View More)

Learners will research and document some of the requirements for mounting an expedition to an asteroid; actively explore potential resources available to space travelers through research, assessment, team cooperation, and exploration simulations;... (View More)

This is a lesson about discerning fact and fiction in news articles. Learners will read tabloid articles about meteorites and decide if the information is fact or fiction. Questions, extensions, and advanced preparation and procedural tips are... (View More)
