A simple experimental apparatus made of rubber band and books is used by student teams challenged with demonstrating the concepts of friction, force, and inertia. This resource is from PUMAS - Practical Uses of Math and Science - a collection of... (View More)

This activity introduces learners to the visible portion of electromagnetic spectrum. A visible spectrum is projected in the classroom using a diffraction grating and learners reproduce it using colored pencils. Filters are also used to block... (View More)

This is a lesson about the motion of a coronal mass ejection, also called a CME. Learners will calculate the velocity and acceleration of a CME based on its position in a series of images from the Large-Angle Spectrometric Coronagraph (LASCO)... (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 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 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)

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)

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)
