What your child practices
This 4th and 5th grade science set (Grades 4 to 5 in Canada) explores Heart and Blood through 6 worksheets and 54 questions. In grades 3 to 5, science asks children to explain why things happen, not only what happens, and Heart and Blood 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. It is aligned to NGSS 4-LS1-1, which focuses on how living things are built, grow and survive. In Canada it matches the BC curriculum for Grade 5. Each PDF includes its own answer key on page 2, ready for you or your child to check. Short on time? Start with the Heart and Blood 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.
- Ask "how do you know?" after each answer to build scientific thinking.
- Let your child predict an answer before reading, then check if the prediction held up.
