field trip to the pond

handout and ppt for Acids and Alkalis lesson focusing on observations and review of neutralization and indicators. I usually use it as a review lesson and get them to make observations and note down what happens at each step of the reaction. If measured out properly by a technician before hand and done carefully by the students (tilt the tubes when pouring as if you were layering a drink) the careful kids are rewarded with a beautiful rainbow effect in the test tube; the others learn to be more careful but are also able to make the observations at each step.

This looks a really good little practical that I'm going to try. Any news on the quantities?
