Sample questions
A taste of this unit. In the app, questions change every time and get easier or harder to match your child.
Question 1
Follow one drop of blood. Start when the heart pumps it to the lungs.
- 🫁Blood picks up oxygen in the lungs
- ↩️Oxygen-rich blood returns to the heart
- 🔄Cells take the oxygen and blood heads back
- 💪The heart pumps it out to the body
- 🫀The heart pumps blood to the lungs
Show answer
The heart pumps blood to the lungs → Blood picks up oxygen in the lungs → Oxygen-rich blood returns to the heart → The heart pumps it out to the body → Cells take the oxygen and blood heads back
Hint: Blood goes from the heart to the lungs for oxygen, back to the heart, out to the body, and then back to the heart again.
Question 2
What holds one bone to another bone at a joint?
- a ligament
- an artery
- a tendon
- a vein
Show answer
a ligament
Hint: Ligaments are strong bands that hold bones together at joints. Tendons attach muscles to bones.
Question 3
Circulatory system or musculoskeletal system? Tap an item, then tap its basket.
Sort into: 🫀 circulatory · 🦴 musculoskeletal
- 🩸capillaries
- 🦴skull
- 🫀heart
- 🦵femur (thigh bone)
- 🔴red blood cells
- 🦴rib cage
Show answer
🫀 circulatory: capillaries, heart, red blood cells · 🦴 musculoskeletal: skull, femur (thigh bone), rib cage
Hint: The circulatory system moves blood. The musculoskeletal system (bones and muscles) supports and moves your body.
Question 4
How do muscles move bones?
💪- by pushing the bones away
- by filling up with blood
- by contracting and pulling on them
- by growing longer
Show answer
by contracting and pulling on them
Hint: Muscles can only pull. When a muscle contracts (gets shorter), it pulls the bone it is attached to.
Question 5
What connects a muscle to a bone?
- a tendon
- a capillary
- a joint
- a ligament
Show answer
a tendon
Hint: Tendons are tough cords that attach muscles to bones. Ligaments join bone to bone.
Question 6
What does your skeleton do for your body?
🦴- takes in oxygen
- supports it, protects organs and helps it move
- pumps blood to the lungs
- digests food
Show answer
supports it, protects organs and helps it move
Hint: Bones give your body its shape, guard soft organs, and work with muscles so you can move.
