Prep & Classroom Structure
Prep:
Watch video to understand the instructions
Have print out ready with pattern instructions
Pre-pack popsicle sticks in ziplock for each group ensuring even # of sticks.
During:
Break students up into groups of 4.
Give a time limit, the goal isnt to use up all of the sticks, but to atleast start a chain reaction together.
During observation have students compare chain lengths, measure travel time, calculate speed, or record slow-motion video to analyze energy transfer.
Considering how much patience this exercise requires, this is best for 4-5 grades.
What's happening: Bent/interlocked sticks store elastic potential energy. Once released, energy transfers from one stick to the next and becomes kinetic energy, producing a traveling chain reaction.
Materials
• 80–150 jumbo 6' craft sticks per team/class station
• Flat table or floor work surface
• Pattern task card
• Safety goggles
• Measuring tape optional
• Slow-motion tablet/phone recording optional (teacher-managed)
Project Instructions
Learn the repeating over-under weaving pattern with 5–8 sticks.
Extend the chain while keeping stored tension controlled.
Stop at a designated length or time and clear the release zone.
Predict the direction/speed of the chain reaction.
Release the end stick.
Rebuild and test how chain length or pattern consistency changes the result.
