General Information

Subject Area: Science
Grade: 912
Body of Knowledge: Physical Science
Idea: Level 3: Strategic Thinking & Complex Reasoning
Standard: Energy -

A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc2.

B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion.

C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy.

D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields.

E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.

Refraction of Light

This resource explores the electromagnetic spectrum and waves by allowing the learner to observe the refraction of light as it passes from one medium to another, study the relation between refraction of light and the refractive index of the medium, select from a list of materials with different refractive indicecs, and change the light beam from white to monochromatic and observe the difference.

Basic Electromagnetic Wave Properties
  • Explore the relationship between wavelength, frequency, amplitude and energy of an electromagnetic wave
  • Compare the characteristics of waves of different wavelengths

Virtual Manipulatives

Name Description
Black body Spectrum

In this simulation, learn about the black body spectrum of the sun, a light bulb, an oven and the earth. Adjust the temperature to see how the wavelength and intensity of the spectrum are affected.

Photoelectric Effect
This virtual manipulative will help the students to understand how the light shines on a metal surface. Students will recognize a process called as photoelectric effect wherein light can be used to push electrons from the surface of a solid.
Some of the sample learning goals can be:
  • Visualize and describe the photoelectric effect experiment.
  • Predict the results of the experiment, when the intensity of light is changed and its effects on the current and energy of the electrons.
  • Predict the results of the experiment, when the wavelength of the light is changed and its effects on the current and the energy of the electrons.
  • Predict the results of the experiment, when the voltage of the light is changed and its effects on the current and energy of electrons.
Molecules and Light

This activity will help to investigate how a greenhouse gas affects the climate, or why the ozone layer is important. Using this simulation, explore how light interacts with molecules in our atmosphere.

Areas to explore:

  • How light interacts with molecules in our atmosphere.
  • Identify that absorption of light depends on the molecule and the type of light.
  • Relate the energy of the light to the resulting motion.
  • Identify that energy increases from microwave to ultraviolet.
  • Predict the motion of a molecule based on the type of light it absorbs.
  • Identify how the structure of a molecule affects how it interacts with light.
