The Shape of the Earth: Oblate Spheroid

• Earth is described as an oblate spheroid, meaning it is somewhat spherical but not perfectly round.
• The term spheroid is derived from the root word "sphere" and the suffix "-oid".
• The Earth's shape is not a perfect sphere because it has a bulging equator and flattened poles.
• The equatorial circumference of the Earth is different from the polar circumference.
• The lesson aims to compare the equatorial circumference and polar circumference of the Earth.
• The lesson also aims to explain the different measurements of the Earth based on its shape.
• Students are encouraged to compute quantities relevant to the Earth, such as mass, diameter, circumference, volume, density, rotational speed, and orbital speed.
• The lesson has a time frame of 30 minutes.
• The components of the lesson include a target, hook, tasks, teaching assistant (TA), and teacher (T).
• The lesson is part of the Earth Science module with the code ES 1.0.
• The lesson is specifically focused on Earth's measurements and properties.
• The lesson code for this particular topic is 1.1.
