Light refraction is the bending of light as it travels through objects. Students got to see this by filling a beaker with water. A smiley face disappeared right before their eyes. Another way to reinforce the objective of light refraction, was putting a pencil in water. Students saw and mastered how light is refracted as it travels through objects. They understood that the speed it travels through objects effects and ultimately bends the light energy. They also got to see a laser passing through different glass objects similar to prism and how the refraction effected the location of the laser dot on the wall. Finally, students read a passage from Gary Paulsen's Hatchet. In this story, the main character, Brain, has to adjust for the refraction while hunting for fish with a bow and arrows.
I hope you enjoy learning how the garden changes throughout the school year.
