Need a quick light lesson? Running out of time? This lesson is the first in a 7 lesson unit that will quickly and effectively prepare the students for a test and give you a science mark. No lesson plan needed! Simply follow the PowerPoint! I designed this unit to have handouts with fill in the blanks so that the students can follow along. The underlined words are the blanks in the handout to be filled out. In the unit I have included all the parts so if you like this type of a lesson then this unit is for you. Includes learning goals and vocabulary for the students to learn.
