About this worksheet
Quick checks of understanding are the aim of this 3-page 5th grade science sheet. Page 1 has five multiple-choice questions with three options each, on the heart's job, red and white blood cells, the gas picked up in the lungs and the size of the heart. Page 2 asks students to match arteries, veins and capillaries to their jobs and to explain in writing why blood goes to the lungs first. The answers are on page 3.
