  • Paper Swing: Demonstrate the strength of seemingly fragile materials like paper by suspending a real person, connecting to lessons on forces and material properties.

Session 3: Energy Transfer and Systems

  • Domino Chain Reactions: Delve deeper into energy transfer systems by setting up larger domino chain reactions, reinforcing the idea of cascading effects in physics and engineering.
  • Self-Organizing Structures: Introduce the concept of self-assembly with metallic balls that form complex patterns under high voltage, connecting this demonstration to molecular and material science.

Session 4: Heat and Sound Waves

  • Rijke Tubes: Use heated metal pipes to generate mysterious sounds, introducing heat transfer and sound wave resonance to students in an engaging way.
  • Flame and Thunder: Explore the nature of plasma in flames and the behavior of electricity in plasma arcs, introducing concepts of high-voltage electricity and plasma states.

Session 5: Fluid Dynamics and Air Pressure

  • Levitating Balls: Revisit this demonstration of fluid dynamics, with a focus on how air pressure can suspend objects in mid-air, linking it to the principles of gravity and pressure differences.
  • Chain Fountain: Demonstrate the strange movement of a 200-foot chain falling from a height, exploring forces, motion, and air resistance.

Session 6: Exploring Optics and Lenses

  • Infinite Mirror: Dive deeper into the concept of light reflection with an infinite mirror, exploring how light rays create an illusion of infinite depth, and introducing optical illusions and mirror systems.
  • Disappear in Lenses: Use convex lenses to make objects disappear, reinforcing optics, focal length, and the behavior of light as it passes through different lenses.

Session 7: Chemical Reactions and Properties of Matter

  • Elephant Toothpaste: Revisit this exciting chemical reaction, diving deeper into the concepts of exothermic reactions, catalysts, and reaction rates, with a more advanced focus on chemical kinetics.
  • Fire in Water (Sodium Reaction): Explore the explosive reaction of sodium in water again, but this time with a focus on oxidation, reduction reactions, and hydrogen gas production.

Session 8: Electricity and Magnetism

  • Lichtenberg Patterns: Use high-voltage electricity to create beautiful branching patterns on wood, introducing the concepts of electrical currents, insulation, and conductive materials.
  • Sound Tunnel: Engage in a deeper exploration of sound waves with parabolic domes, linking it to lessons on sound propagation, acoustics, and the science of communication.

Session 9: Understanding Materials and Structures

  • Hex Games: Introduce the concept of geometry and logic through fun, interactive board games where students solve puzzles using hexagonal tiles, linking to lessons in pattern recognition and logical reasoning.
  • Lizards: Explore how calculated, irregular shapes (lizards) fit together, teaching students about tessellation, geometry, and spatial reasoning.

Session 10: Student Demonstration Day

  • DIY Demonstrations: Allow students to select and perform their favorite demonstrations from the previous sessions, encouraging them to explain scientific principles and showcase their understanding through public presentations.
