Notebook Entry: This picture is not photo shopped! You are actually looking at a full circle rainbow. How could this be possible? What do you think creates rainbows?

2. Why do rainbows usually only appear after rain?

3. Light enters a water droplet, bending as it slows down a bit going from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths—or colors. When it exits the droplet, it makes a rainbow.

4. Energy from the Sun
Nearly all of the energy in earth’s atmosphere comes from the sun.
The energy travels in a wave and is called radiation.
Light, heat, and sound are all forms of radiation.

5. Energy in the Atmosphere
Task: Create Outline form notes for the reading lesson.

6. Energy in the Atmosphere
Absorb = occurs when bundles of electromagnetic energy from light hit atoms and molecules and cause them to vibrate.
The more an object's molecules move and vibrate, the hotter it becomes.
Reflect = light energy is NOT absorbed and instead bounces off the object
Radiate = light energy is absorbed by atoms and sent back out as heat (infrared radiation)
