I made this environmental coloring sheet, because I wanted to emphasize the importance of the LD-50 and the mode of action of pesticides. I think this is important for students to understand in class, but also in life. I suggest making a second part to this or a backside that includes having the students explore http://www.irac-online.org/modes-of-action/. It is an excellent resource. In my own class, I had the students then search out the MSDS sheets on the selected insecticides. I think it is important that they know how to access the MSDS sheets of pesticides and know that they are easily accessible. This coloring sheet focuses on 5 different types of pesticides.
