Final answer:
I observed that the length of the shadow changed throughout the day due to the movement of the Sun across the sky. Shadows were shorter when the Sun was higher in the sky and longer when the Sun was lower. The data chart recorded the length of shadows at different times of the day.
Step-by-step explanation:
As I completed the task of measuring shadows each time, I observed that the length of the shadow changed throughout the day. This change in length was due to the movement of the Sun across the sky, causing the angle of the sunlight to change. When the Sun was higher in the sky, the shadows were shorter, and when the Sun was lower in the sky, the shadows were longer.
Repeating the attempts allowed me to notice a pattern in the changing length of the shadows. I observed that as the day progressed, the shadows grew shorter until they reached their shortest length when the Sun was at its highest point in the sky around noon. After that, the shadows started to lengthen again as the Sun moved lower in the sky towards sunset.
To better understand this pattern, I created a data chart to record the length of the shadows at different times of the day. You can find the chart uploaded here.
