Explore The Pepper's Ghost Illusion to make your own ghosts for LockWood & Company to chase
In Jonathan Stround's The Screaming Staircase
(Lockwood & Co. #1), our fearless ghostbuster trio take on a lot more than ghosts. This series is popular with students and makes a great connection to optical illusions. The Pepper's ghost illusion was made famous in 1862 by John Pepper when he used it during a demonstration. The illusion is still used today in haunted houses, theaters, concerts and now ....learning spaces! This would be a great library Makerspace heading into Halloween.
Resources:
- Briana Costa provides a nice history of Pepper's Ghost along with a how-to create your own illusion using a plastic CD case and a cell phone.
- For younger students, check out this technique from Instructables.
Vocabulary:
- light
- optical illusion
- angle
- video
- holographic effect
- reflection
- material
- image
Learning objectives:
- make predictions using scientific knowledge and understanding
- interpret observations and data, including identifying patterns and using observations, measurements and data to draw conclusions
- the transmission of light through materials: absorption, diffuse scattering and specular reflection at a surface
- colors and the different frequencies of light, white light and prisms (qualitative only); differential color effects in absorption and diffuse reflection
- generate, develop, model and communicate ideas through discussion, annotated sketches, cross-sectional and exploded diagrams, prototypes, pattern pieces and computer-aided design
- understand and use the properties of materials and the performance of structural elements to achieve functioning solutions
