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.
