STEM Activity: Elf Workshop Chain Reaction

Innovation is all about collaboration. If elves work together, they can develop all kinds of innovations to improve their workshop efficiency.

What kind of chain reaction could help elves meet their quotas? A chain reaction is a series of events where one thing makes the next happen, which makes the next event happen. In other words, chain reactions demonstrate cause and effect. Think of a domino effect or the momentum of a marble maze. With this activity, you can design your own mini model of an elf workshop and build in a chain reaction that will bring your workshop to life through physics!

Materials Needed:

• Craft materials (e.g., clay, fabric, toothpicks, wooden spools, etc.)
• Glue or alternative adhesive
• Recyclables (e.g., bottle lids, cardboard pieces, creamer cups)
• Spare toy and game parts (e.g., marbles, small figures)

Step-by-Step Instructions:

1. Brainstorm items you might discover in an elf workshop. Explore which materials can be used to make toys, tables, tools or chutes.
    
2. Find materials to make a mini model of an elf workshop. Clay, marbles, toothpicks, balloons and other crafting materials can help you create a one-of-a-kind workshop.
    
3. Research chain reactions and consider how they can enhance your workshop. There are plenty of chain reaction videos that will inspire you!
    
4. Challenge yourself to create a chain reaction that has at least three steps. For example, maybe your favorite marble rolls through a paper towel roll and knocks over a mini book that causes an elf tool to drop into a box.
    
5. Build your model with a friend or family member. Stay persistent as you tinker and tweak your chain reaction.
    
6. Invite a friend or family member to try it out!

What Are We Discovering?

Chain reactions are an important part of science! In the world of physics, chain reactions are described as reactions that initiate their own repetition, creating a cascading effect of fission events.

If you have ever played with polymer snow (a great addition for an elf workshop!), then you have experienced how large molecules link together in repeating chains to form a polymer. The polymerase chain reaction, which was devised by National Inventors Hall of Fame^® Inductee Kary B. Mullis, has revolutionized DNA technology. It has made a major impact on molecular biology, medicine, forensics, molecular paleontology and many related fields.
