Students received three items (wire, light bulb and battery) and had to make the light bulb shine. After a few minutes of trial and error, they became successful in lighting the bulb, Students learned that this was a circuit. It was a closed or complete circuit when light bulb was on and an open circuit when the light bulb was off. Besides making a complete circuit, student had to view illustrations of circuits, predict if they were closed or open, and finally tested them to using their tools.
I hope you enjoy learning how the garden changes throughout the school year.
