Understanding Water on Earth

This video tutorial guides students through an activity to explore the distribution of water and land on Earth's surface. Students will use a world map, ruler, and colored pencils to draw a grid and color squares based on whether they represent land or water. They will then count and record the number of colored squares to analyze the data and communicate their findings. The activity encourages students to predict, observe, and discuss patterns in Earth's water distribution.
