Learn about and engage with backward design: a scalable, end-in-mind approach to instruction that will help you effectively plan an activity, a class session, or an entire course. In this workshop for ...

To get some very basic descriptions of the Earth we will start by describing some of the simplest of all the Earth's properties - how big, how heavy, how hot, how strong - and how they were deduced.

1.2 Mass of the Earth: Cavendish's Experiment to "Weigh the Earth" The next thing is to try to find out how much the Earth might weigh. This is much more difficult, and requires a very cunning ...

Relating what Erastosthenes did to the ideas in our opening comments, we would say that the data available to Erathosthenes was the curious observations of shadows in wells and sticks. He then used a ...

Because of this he knew about angles. At that time the concept of "angle" was still new and it was cast in terms of ratios in two different ways. Erastosthenes measured the sun angle on the longest ...

Given a sufficiently large earthquake, like the so-called Good Friday earthquake in Alaska in 1964, which had a magnitude of 8.6, the entire Earth actually vibrates. It is fairly intuitive that the ...

With this simple formula, Cavendish established the mass of the Earth using a very accurate balance beam by the following steps - ...

Centuries ago people had very little idea about the total size of the Earth and hardly any notion of its shape. Few people traveled very far because transportation was difficult. So the total size of ...

Heat is a form of energy and is transported through the Earth. In general the direction of heat flow is outward. Heat energy is transported in the Earth by two primary mechanisms - Conduction - in ...

What we have learnt about in the first Topic are large-scale (macro) properties of the Earth. They are also mostly "static" properties - that is, properties that pertain to descriptions of the Earth, ...
