Students mastered the concept that light travels in a straight line and reflects off of smooth, shiny surfaces. In order to understand that light travels in a straight line, students had to shine a flashlight through 4 alined cards that contained holes. After seeing the result of the light on the wall, this confirmed that the light was traveling in a straight line. Afterwards, reflection was confirmed by shining the flashlight through 3 tubes with 2 mirrors reflecting the light in straight pathways onto the wall.
I hope you enjoy learning how the garden changes throughout the school year.
