What your child practices

Curious about Germs and Your Defences? These 6 worksheets give 4th and 5th grade students (Grades 4 to 5 in Canada) 54 questions to think through. In grades 3 to 5, science asks children to explain why things happen, not only what happens, and Germs and Your Defences is a great place to practice that kind of thinking. It opens with a guided Learn and Practice page, moves on to a practice sheet and a review test, then finishes with two quick quizzes and a mixed review. The skill matches NGSS 4-LS1-1, the standard for how living things are built, grow and survive. In Canada it matches the BC curriculum for Grade 5. Answer keys sit on page 2 of each PDF, so checking takes seconds. Before printing, try the Germs and Your Defences video lesson, then print a sheet while it is fresh.
