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.

Divide the children into groups of 2–3. Begin with a story, such as tiny villagers trapped on top of a tower or toys stuck at a height who need help, to spark imagination and purpose. Give each group cardboard, popsicle sticks, straws, and string, and explain that their challenge is to design a rescue device that can safely lift small objects upward from the ground. Encourage them to think about stability, strength, and how simple machines like pulleys or levers could help. If children face difficulties, give hints such as: How can you make the base stronger? Which parts should move? How can the device lift without tipping over? Allow time for each group to test, adjust, and finally use their rescue device to “save” the object, making the activity both fun and meaningful while exploring stability, structure, and creative problem-solving.
