Day and Night - Worksheet

This science activity worksheet is designed to help students understand the concept of day and night through a practical experiment. The worksheet instructs students to place a stick in the ground on a sunny day and observe the shadow it casts. They are tasked with measuring the length of the shadow at various times throughout the day, such as at 09:00, 12:00, 15:00, and 18:00, and recording their observations. The aim is for students to notice the changes in the shadow's movement and length, which are influenced by the position of the sun in the sky as the Earth rotates.

In addition to the practical activity, the worksheet includes a series of questions designed to deepen students' understanding of the Earth's rotation and its effects on our perception of day and night. The questions prompt students to explain why the Earth experiences night and day, what time of day it is when the Earth faces away from the sun, the reason for cooler temperatures at night, and why it is day on one side of the Earth while it is night on the other. Furthermore, students are asked to consider why the sun appears to move across the sky during the day. These questions encourage critical thinking and help students to grasp the scientific principles behind the natural phenomena of day and night.
