This is Our World

Learn about our world and where we live. Discover that the earth is made up of land and water. Identify the seven continents and the four oceans. Compare the earth to a map and a globe and understand the placement of the equator and poles. See how the earth moves around the sun, creating day and night in different places at different times.

Our world in called Earth. People, plants and animals live all over the Earth.

  1. Students will understand the characteristics of our world, Earth.
    1. Earth is made up of land and water. The large bodies of land are called continents. There are seven continents: North America, South America, Europe, Africa, Asia, Australia, and Antarctica. These continents contain areas of land with different shapes called landforms. Examples of landforms include mountains, hills, valleys, and plains.
    2. On each continent, there are bodies of fresh water, including rivers and lakes (the fresh water on Antarctica is frozen). These freshwater bodies provide much needed water for people, animals, and plants to use. There are larger bodies of salt-water called oceans; the four oceans are the Pacific, the Atlantic, the Indian, and the Arctic.
    3. The Earth is like a very large spinning ball. It is the Earth's spin that is responsible for night and day periods. Since the sun is stationary, only one side of the Earth can be exposed to the light. However, because the Earth spins, each side of the Earth experiences a period of darkness and a period of sunlight exposure.
    4. The Earth has two poles. The North Pole is the northernmost point on the Earth, and the South Pole is the southernmost point on the Earth.
    5. Students will observe that the Earth's continents are divided into areas of land where people live together and follow the same rules; these areas are called countries. The United States, for example, is a large country that stretches across the continent of North America from the Pacific Ocean to the Atlantic Ocean. The United States is divided into smaller areas called states; there are 50 states in the country.
  2. Students will realize that maps and globes are made to help us understand the characteristics of Earth.
    1. Maps are flat pictures of the Earth; they may show only parts of the Earth or the entire Earth.
    2. Globes are true models of the Earth, meaning they are exactly like the Earth, however, they are much smaller. Looking at a globe, one can see lines (including the equator) running across it. Using these lines one can determine the location of places on the Earth (note these lines do not actually appear on the Earth).

  1. Model of the Earth: Make a paper mâchè model of the Earth. Have students paint their Earth with the appropriate oceans and continents, and label their country, state and city.
  2. Interview Project: Have students take home a piece of paper with an interview question on it. Have them ask a member of their family the question, and have that family member write down their answer. Then the child should draw a picture to illustrate the answer. Possible questions: What state did you grow up in? What landforms are in your home state? What is your favorite state to visit? Students who write well should be allowed to write down the interview answers.
  3. Song: This is our World Our home in space And Earth is the name We call this place The Earth is like A spinning ball And it is home For one and all There are continents, And oceans too Spreading East and West, North and South too! Lands and Countries People too So diff — er — ent, yet so like you! This is our world Our home in space And Earth is the name We call this place The Earth is like A spinning ball And it is home For one and all!
