Today we are: Looking at different ways light can be produced. |
We will: Learn the new vocabulary watching some you-tube videos. |
I will show you I understand: By completing the questionnaire. |
1. Watch this please. When done, login to Moodle and make a blog posting.
2. Incandescent light sources are the idea light bulbs. Watch this video to see how it works and this video to see how it's made.
3. Chemiluminescent is light from a chemical reaction. Watch the first 2 minutes of this video to see what is really going on in glow sticks.
4. Bioluminescent is light from a reaction in living things. Watch this video to see how it works and here are some cool examples.
5. Phosphorescent and Florescent are very similar. This video compares them. This is the hard one, so I'll help you. Phosphorescence can use regular light to glow, but Florescence needs higher energy light or what is known as UV light. Here is a quick video that shows a Florescent light bulb.
6. All Done! If you think you got it, complete the questionnaire.
