How Lasers Work (In Theory)

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Help your class become laser focused on the connection between sound and light. Scholars set up mirrors to bend and direct lasers that are connected to a music source. Music should start playing when the laser hits the photoresistor.

Have you ever wanted to play with a giant pendulum? An experiment allows small groups to do just that. They gather data and make observations as they complete the included worksheet. The activity lays out each instruction including how...

See what you cannot see by getting a little creative. An intriguing lesson has learners use lasers to explore X-ray diffraction. Given a box with unknown structures, they shine a laser through the box and interpret the results....

The tension of the 236 strings in a grand piano exert a combined force of 20 tons on the cast iron frame. The presentation includes topics such as work, forms of energy, conservation of energy, gravitational and elastic potential energy,...

What makes a clock tick or a bulb light up? The concept of work is explained to a backdrop of clever animation. Physics fans learn that the amount of work equals the product of the force and distance, and that the rate equals the amount...
