#### LAB: Marshmallow Speed of Light Lab

Description: A simple take-home lab in which students melt marshmallows in a microwave to experimentally determine the speed of electromagnetic waves in air using the wave equation and the given frequency of the microwave.

Objective: Determine the speed of light experimentally

Materials:
Microwave
Bag of marshmallows (preferably mini's)
Casserole dish
Butter
Metric ruler
Rice Krispies or graham crackers and chocolate

#### LAB: Snell's Law with Lasers

A short lab in which students experimentally determine the absolute index of refraction for Lucite using two different shaped blocks (rectangular, triangular). Easily adaptable to other materials and shapes.

Materials:
Lasers
Transparent blocks
Protractors
Straight-edges

#### LAB: Wave Speed with Standing Waves in Springs

A lab in which students oscillate an extended spring to create standing waves. By measuring the period or frequency of the standing waves, as well as the wavelength, students calculate the speed of the wave using the wave equation.

Ultimate goal of this lab is to have students understand that the type of wave and the medium determine the speed of the wave. The wave equation, holds true and describes a relationship, but the speed of the wave is not determined by adjusting the wavelength or frequency.

Materials:
Long springs
stopwatches
meter sticks
