Dragonfly Sight: UV Light and Electromagnetic Waves

Explore the electromagnetic spectrum with UV beads. Participants will use UV beads to learn about different types of light and do a wave dance to visualise how waves move. The demonstration will centre a discussion on wavelengths of light humans cannot see but dragonflies can. 

This demo pairs well with Dragonfly Colours: Thin-Film Interference and Dragonfly Flight: Waves and Wing Movement. This demo is part of the 2024 SOCK, The Wonders of the Dragonfly.

Dragonfly Flight: Waves and Wing Movement

This three-part demo allows participants to use several senses to learn about wave phases, wave superposition, and constructive and destructive interference. Participants build moving wave models, do a phase shift dance, and visualise interference with ropes. 


This demo pairs well with Dragonfly Colours: Thin-Film Interference, Dragonfly Sight: UV Light and Electromagnetic Waves and Transverse and Longitudinal Waves. This demo is part of the 2024 SOCK, The Wonders of the Dragonfly.

Physiological Cost Index

Test how much energy is required to walk, run, or hike by measuring factors such as heart rate, oxygen uptake, and respiratory quotient.

Brain Reaction Time

Discover how long it takes for the brain to react to a stimulus by catching a ruler as fast as you can.

Planet Deformation

Construct a planet and watch how the rotation of the planet changes the shape!

Rodent Reactor

Use mousetraps and ping pong balls to understand how nuclear reactors work.

Longitudinal and Transverse Waves

This demonstration uses a slinky and tuning fork to explain two types of waveforms in our world: transverse and longitudinal. A discussion on sound waves is included and leads to categorizing sound waves as longitudinal waves.

Vortex Cannon

Build a device that releases ring shaped air vortices that are visualized using smoke to show the wonders of fluids

Cakeraters

Falling space rocks collide with the surface of planets and moons to create impact craters which can be found all over our solar system
