Summary of clip: Tyler creates a chemical burn on the narrator's hand by pouring lye powder on him. His flesh begins to sear instantly and you can tell he is in sever pain. He tries to get to water, but Tyler tells him, "You can run water over your hand and make it worse or you can use vinegar and neutralize the burn."

Connection of flickclip to the concept: This flickclip could lead into a discussion on how serious chemical burns are and why we must be careful when using any chemicals. It could be an introduction to a lesson on acids and bases since it shows the neutralizing abilities of acids and bases.
Suggestions to teachers:

1. Prior to the flickclip have students discuss what they know about acids and bases.

2. Make a concept map of everything they know.

3. Watch the clip on the neutralizing abilities of acids on bases and add this new concept to the concept map.

4. Experiment idea one: run a simple experiment using acid-base indicators to figure out whether substances are acids or bases. Then mix an acid with a base; checking the pH every few drops with a Universal Indicator until you neutralize the solution to a pH of 7. Don't forget: Safety first!

5. Experiment idea two: Show how to use a solution of phenolphthalein (range of 8.3-10) to find the strength of an acid. Using a calibrated basic solution, measure the amount of base needed to completely react with, and neutralize, a known amount of acid. This would be indicated by the phenolphthalein: in contact/presence of acid it will turn colorless and when in presence of a base it will turn into a pinkish violet color, at < 10 it turns bright orange.
