How Small is It?

Pupils better understand what a concentration of one part per million means through activities. Students discuss "Maximum Contaminant Level" of a toxic in the water. They measure the classroom to find out how many cubic centimeter blocks are needed in the classroom to represent one part per million. They determine the number of sheets of paper needed to have one million square centimeters, and determine the number of drops of water in one milliliter.

As a first year teacher, Lesson Planet is a precious lifeline! I am able to gather ideas and build on the ideas of veteran teachers. Lesson Planet is a huge time saver, especially for a first year teacher who is trying very diligently not to become overwhelmed!
