I am wanting to introduce the water cycle to my students. I am searching for the Killer Chemical worksheet. It was a descriptive sheet that had all of the characteristics of water and some statistics about it being the number one killer in agriculture but is essential for the existence of life. It is really good to get the students thinking about what chemical they are trying to identify and why it's essential to life but is extremely dangerous. Does anyone have this sheet? Please and thank you?
