Science Phenomena: HS Physical Science - Forces and Interactions - Special caution should be taken when sitting down or getting up from a bed of nails. In this video, Steve Spangler used a motor to lift the entire bed of nails up and down safely. Each of the nails is pushing on the participant but since there are so many nails the force is distributed safely between all of the nails. This demonstration could be used in any physics unit discussing forces and pressure.
Science Phenomena: HS Physical Science - Energy - As ocean water freezes into solid ice the remaining saltwater forms into icy "stalactites" that descend into the ocean. This can be used as a phenomenon in an elementary class to show changes in state. In middle and high school the chemistry can be explored more deeply.
Science Phenomena: HS Physical Science - Waves and Information - Daniel Kish lost his eyes to cancer before he was 13 months old. He uses echolocation by listening to the reflection of sound waves to navigate in 3D space. He can even ride a bicycle. In addition to being an incredible story of perseverance this is a perfect phenomenon for a unit on waves. Sound waves are reflected, absorbed, and transmitted through objects in the environment and Daniel can sense the changes in energy of the returning waves.
