What your child practices

Lungs and Breathing comes alive in 6 worksheets for 4th and 5th grade science (Grades 4 to 5 in Canada), with 54 questions in total. In grades 3 to 5, science asks children to explain why things happen, not only what happens, and Lungs and Breathing 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. Each sheet supports NGSS 4-LS1-1, covering how living things are built, grow and survive. In Canada it matches the BC curriculum for Grade 5. Every PDF prints on US letter paper, with the answer key on page 2 for quick checking. Short on time? Start with the Lungs and Breathing video lesson, then print a sheet while it is fresh.

Tips for parents

  • Ask your child to explain the idea using a diagram or a quick sketch.
  • Keep a small science notebook for drawings and questions that come up.
  • Ask "how do you know?" after each answer to build scientific thinking.
