The inverse square law is revealed when your class participates in this activity. They move a graph paper or perfboard square back and forth in a square of light to see how the intensity changes. You will definitely want to add this...

Light, distance, and mathematics come together to help scientists plan for space missions. Groups examine the relationship between distance from the sun and light availability in a hands-on exploration activity. They model the inverse...

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...

An introductory exploration of the nature of light is provided via activities and demonstrations. Science superstars observe various light sources, learn how to apply inverse square law, and practice using a light meter. Follow-up...

Are these two light sources the same? Groups use a white card and a little cooking oil to create a photometer that allows for the comparison of two lights. The Inverse Square Law provides a way to calculate the actual difference in...

Get ready to spark interest in electromagnetic radiation! This resource shares nine indelible inquiries that you can choose from to ignite understanding of spectra and the relationship between light and heat. The assessments that follow...

Students apply an algorithm to measure the distance to stars in the night sky. In this photometry instructional activity, students observe stars in the night sky as they measure the distance to them and to the cluster, The Milky Way....

In this math worksheet, students are given 8 questions regarding Kepler's first law of motion. The questions include definitions, short essay explanations, and formulaic expressions.

Investigate light intensity, illuminance, and power consumption of different light source.Compare the efficiency of light bulbs then create a persuasive advertisement about it.

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Learners identify the different requirements for photosynthesis to take place. In this space science lesson, students simulate conditions in Saturn to investigate if photosynthesis is possible there. They use data and observations...

Learn about how the intensity of light is governed by the inverse-square law with this activity. Activity has you experimenting to find that the intensity of light decreases as the inverse square of the distance.

You've probably heard that compact fluorescent light bulbs are more efficient than incandescent bulbs. More of the electricity they use goes into producing light, and less into producing heat than with incandescent bulbs. How much more...

How far would you have to travel so that the light of the full sun would provide "daylight" no brighter than twilight on Earth? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and...

In this activity, students can use a light sensor to record the light intensity at various distances from a bulb. They will compare the data to an inverse square and a power law model.
