Bones and Muscles Worksheet
Help the Motion Lab team solve a series of body-system challenges. Read each question carefully, use what you have learned, and explain your thinking where asked.
Build and protect
1.At the Motion Lab, Logan is designing a robot body. Which feature should she copy from the human skeleton to help protect the brain?
- The skull surrounds and protects the brain
- The femur pumps blood to the brain
- The ribs digest food
- The spine makes muscles contract
2.A model skeleton has 206 small counters representing the bones in an adult human body. Why is the skeleton useful besides giving the body its shape? Choose the best answer.
- It protects organs and helps the body move
- It digests meals and makes oxygen
- It carries messages from the eyes
- It turns food into muscle
3.Match each body part or tissue to its job in the movement team.
- Tendon
- Ligament
- Cartilage
- Joint
- Cushions the ends of bones at many joints
- Connects muscle to bone
- Connects bone to bone at a joint
- Place where two or more bones meet
Movement in action
4.From what you have learned about the skeleton, name the long bone in the thigh and the bones in the chest that help protect the heart and lungs.
5.When you bend your elbow to lift a light box, muscles work in pairs. Describe what happens to the muscle on the front of your upper arm and the muscle on the back of your upper arm.
6.A student says, “Bones move by themselves, so muscles are not needed.” Correct the student's idea by explaining how bones and skeletal muscles work together to move a leg during a step.
7.Sort each example by muscle type: moving your arm on purpose; your heart beating; food moving through your intestines. Write skeletal, cardiac, or smooth beside each example.
Think like a body scientist
8.A bone fracture is a crack or break in a bone. Put these general healing events in the correct order by numbering them 1–3: new bone tissue gradually bridges the break; a blood clot forms around the break; the body removes damaged tissue and builds a soft repair tissue.
9.True or false: The skeleton only supports the body; it does not protect organs or help make blood cells.
TrueFalse
10.Exit ticket: Choose one bone or muscle fact from this worksheet that would help you explain how the body moves or stays safe. Write the fact and why it matters.
