A great list by subject for videos, including worksheets! The Super Size Me worksheet even has before AND after questions.
Please click "Add Child Page" to recommend videos to show in a science classroom. Please include the following info: (and attach study guide please if you have it!)
- Distributor (PBS, National Geographic, etc.)
- Where found (Berkeley Unified Digital Library, Explo Library, Blockbuster, Netflix, Etc.)

When I suddenly fall ill, or otherwise don't want to take 10 hours to plan a sub lesson, I usually go online to http://puzzlemaker.school.discovery.com/ and plug in some vocab words for some puzzles (they have some pre-made banks of words also!)
I make four puzzles using the exact same list of words. I usually start them with the word search (even non-readers can do this!) then go on to word scramble, then crossword. This because they need to know the words pretty well by the time they get to the crossword - also, the word search has the word bank on it.
In response to a question on ways to teach electron configuration to students, here's a model I used with my 8th graders. We had been using beans to represent and build 2D models of atoms (green lentils = electrons, white beans = protons, black beans = neutrons). I made a handout for them to help them understand the idea of where electrons like to go when they are added (download it at the bottom of this page).
Here's a great web resource:
This is a test bed for posting to Irene's website. I'll be posting at least one full lesson as the semester progresses. My hope is to develop a series of ooey-gooey usshy-gusshies to provide visceral experiences as foundations for particle awareness.
The liquid is bromthymol blue (BTB) a non-toxic acid-base indicator that can be used to indirectly measure levels of dissolved carbon dioxide (CO2). The amount of CO2 in a solution changes the pH. An increase in CO2 makes a solution more acidic (the pH gets lower). A decrease in CO2 makes a solution more basic (the pH gets higher). The reason for this is that carbon dioxide that is dissolved in water is in equilibrium with carbonic acid (H2CO3).
CO2 + H2O ↔ H2CO3
In any solution, while the majority of CO2 stays as CO2, some of it is converted to H2CO3, turning the solution slightly acidic. If CO2 is added to the water, the level of H2CO3 will rise and the solution will become more acidic. If CO2 is removed from the water, the amount of H2CO3 falls and the solution becomes more basic. Thus, acid-base indicators such as BTB can indirectly measure the amount of CO2 in a solution.
For more than you ever wanted to know about carbonic acid, see the Wikipedia article on carbonic acid. For the example lesson plans developed by Bob Culler through Access Excellence at the National Health Museum. For a great time lapse video showing BTB color changes using elodea and snails, see Activity C13 from Addison-Wesley’s Science 10 curriculum.
