Topics
- Molecules
- Photons
- Absorption
- Light
Description
Adjust light source slider and begin your observations of how different molecules react to different light sources. Note that the interactive elements in this sim have simple description that can be accessed using a screen reader.
Sample Learning Goals
- 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
