In this introductory activity, students are introduced to the fundamental tools of scientific inquiry: observing, identifying changes, perspectives and patterns. Materials needed include student journals, pencils, crayons, plastic sample bags,... (View More)

Audience: Elementary school
Materials Cost: 1 cent - $1 per student

In this inquiry investigation, students learn that while the Sun appears to move around the Earth, in fact it is the Earth spinning around on its axis while the Sun remains stationary. Materials suggested for this activity include an easel or wipe... (View More)

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)

Students will collect samples of particles in the air on simple slides they make themselves. They will classify, count and chart their findings, draw conclusions, make predictions, and compare their findings to other available data. Supplies needed... (View More)

In this introductory global change investigation, students gather and record visual and written data from their surroundings, and through analysis, show how the sampling window chosen for examination can affect an outcome, sometimes resulting in... (View More)
