In this inquiry investigation, students explore how light hits things of different shape and form. One real world application to this activity is understanding what we actually observe when we see a solar eclipse. Supplies needed for this lesson... (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)

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)

A caller on an automotive-themed radio program asked for help with a problem. It seems that when it rained her windshield wipers sometimes turned themselves on. How is this possible? This resource provides an explanation by exploring electrical... (View More)

This hands-on activity demonstrates how the combining two fluids (confluence of two rivers, Mediterranean water spilling over the straits of Gibraltar into the Atlantic) involves two processes: (1) stirring - stretching of the bulk fluid, and (2)... (View More)

Using the reflection seen in the bowl of a spoon as an example, this resource describes how an everyday childhood observation can lead to understanding how curved mirrors are used in telescopes and satellite dishes. This resource is from PUMAS -... (View More)

In this activity, learners will determine the factors affecting the appearance of impact craters and ejecta on the Moon. Extensions are listed. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use... (View More)

This is a lesson about planet formation. Learners will observe and describe differentiated samples in the Meteorite Sample Disk (or photographs), conduct experiments to model the separation of light and heavy materials within a planetary body,... (View More)

This is a lesson about the connection between meteorites and asteroids, focusing on remote-sensing techniques using light. Learners will make and record observations and measurements; analyze data and draw analogies; compare samples; measure and... (View More)
