Speed of Light with a T.V Receiver

Day Lab

You’ll learn about television transmission, antennas, and the principles of picture-tube scanning while engaging in a new approach to a cornerstone physics experiment: Measuring the Speed of Light

Polarized Light

Day Lab

Through the analysis of the plane of polarization of polarizing filters and photoelastic stress activities, you will explore the effect of polarization of electromagnetic radiation, specifically light. You will find out that transverse waves can be sent through a filter which blocks all waves all waves except those that are parallel to the plane of polarization.

Charles Brass


Antoinio Wood


Surfin’ the Waves

Day Lab

A thorough investigation of the physics of waves. Concrete examples of basic wave theory. The Doppler Shift Principle will also be explored.

April Whitt,


Wardell Minor


Spiral Galaxies

Day Lab/Night Lab

You will observe galaxies through the 10 inch telescope. Images of the observed galaxies will be captured with a charged-coupled device (CCD) image. You will compare both observations .Finally, you will use Hands On Universe software to do an analysis of the objects observed. You will find out how astronomer’s developed a density wave theory of the appearance of spiral arms.

Water Waves Explorations

Day Lab

You will explore characteristics of waves (diffraction, reflection, refraction, interference, wavelength, and amplitude) by examining ordinary water waves as well as some special cases like storms, rocks, and tidal waves. You’ll discover that there are certain behaviors common to all kinds of waves.

Waves of Light and Sound

Day Lab

You will use a PASCO motion probe to collect data on distance and velocity. They will use the Light sensor, also. Challenged to figure out how the sensors works in relation to waves, you will further develop the concept of the difference and similarities of the behavior of mechanical waves versus electromagnetic waves.

Observations of the Night Sky

Night Lab

See the night sky through the world’s largest refracting telescope, Yerkes 40 inch telescope.

Kyle Cudworth


Turn Left at Orion

Night Lab

You will review the celestial coordinate system, using star maps. You will locate the positions of deep sky objects and decide the order in which to observe them. With a partner, you will then use "starhopping" and the MAS telescopes to locate each object in the current evening sky.
