Joining Joints!
Primary | Health | Views: 897
What You Need:
- Straws
- Pipe cleaners
- Scissors
What You Do:
- Thread a pipe cleaner through a whole straw. Try to move and bend the pipe cleaner around – is it flexible?
- Now, cut straws into pieces, each about 2-3cm long.
- Thread a pipe cleaner through the straw segments. Add enough straw segments so that they are touching.
- Bend the pipe cleaner and see what happens! This represents our joints – how they join rigid bones together and allow our bodies to move and bend.
How does it work?
- A joint is where bones meet, these are represented by the straw segments in our model.
- Some parts of our body have many joints, such as our hands and feet.
- Other body parts have one long bone, like the single straw and pipe cleaner, such as our thigh and arm.
- Our bodies need to have both types of bones – for stability, strength as well as flexibility and movement!
