Third Grade Shadow Tracking
We started our investigation by learning how to use a compass and locating the four cardinal directions.
We then went outside and traced our shadows in the morning. We examined from which direction the sun was rising and which direction our shadows were pointing.
Later that same day, our third graders went back outside to trace their shadows again. This time they noticed something had changed. Not only was the sun in a different position in the sky, but our shadows were a different shape and pointing in a different direction.
These observations led us to explore the following important questions in order to understand the relationships between our shadow, the sun and the movement of the earth:
● Why do you have a shadow?
● What did you observe about your shadow?
● Why do you think your shadow changed over the course of the day?
● When do you think you will have the longest shadow? The shortest shadow?
From this experience, our third graders worked as collaborative scientists to reach the following science benchmarks.
● Collect the data in an investigation and analyze those data to develop a logical conclusion.
● Know sunlight can be blocked to create shadows.
● Know the position of the sun in the sky changes during the day.
