Students triangulate using a compass, topographical (topo) map and a view of outside landmarks. They take a field trip to another location away from school and mark discernible landmarks (like mountains or radio towers) and changes in...

Students explore scientific observations by examining the parts of a microscope. In this optics instructional activity, students discuss the importance of a focal point and focal distance when utilizing an optical device such as a...

In this solar tsunami worksheet, students are given three images of the progress of a Morton Wave on the sun. They solve six problems using the images to find the radius of the sun's disk, the scale of the image, and the time that passed...

Students experiment with a simple periscope to see how it reflects light. They draw a diagram of the path a ray of light follows as it travels from an object, through the periscope, and into your eye.

Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Young scholars construct a simple refracting telescope. They calculate the magnification.

High schoolers experiment with a converging lens. They observe the image of an object through a lens. They determine the magnification of the lens.

Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
