Let’s Talk About It

As a class, review students’ answers to the crossword puzzle. If a group was not able to complete one or more line of the puzzle, have another group explain its correct answer to insure that everyone has a clear understanding.

Lead the students to understand that there are three levels of protection within the body’s defense system. It is important for students to grasp that the body has multiple ways to protect itself against disease-causing organisms.

Many students take our bodies’ first layer of defense–the skin–for granted. Ask them to think about what they do when they get a cut or scrape on their skin.
