Straw Rescue Device


Children design rescue devices using cardboard, popsicle sticks and straws to lift small objects upward from a height. This activity builds understanding of stability, structure, and simple machines through creative problem-solving.



Materials :
  • Straws
  • Cello Tape
  • Scissors
  • Cardboard
  • Thread
  • Popsicle Stick

Challenges:


  1. Ask them to make their own model rescue device.
  2. Change or add different weights to be rescued. Ask the kids if they think anything should be changed in their rescue device to handle the new weights.
  3. They can try to figure out how their device can lift the load from the bottom to the top, which might be a fun challenge.

Questions to be asked:


  1. How could we make sure the straw rescue device is safe for the one we are helping? What can be done?
  2. If the load is more, what changes will you bring to your rescue device?
  3. If the depth is more, what changes will you bring?
