200 Countries and 200 Years in 4 Minutes

Here’s an interesting video that shows the evolution of world history.

It shows changes for 200 countries over 200 years.

Technically, it’s quite interesting. But, for student writers there is another use.

We can use this video and data to learn how to write a hypothesis sentence.

What’s a hypothesis? Keep reading.

Hypothesis Sentence Patterns

A hypothesis is a sentence which shows us how two different things are connected. Here is an example:

the more water a plant gets, the faster the plant will grow.

In this example, we are connecting two things: 1) quantity of water and 2) speed of plant growth.

When writing a hypothesis sentence, there are generally four kinds of sentences:

  1. the more this, the more that
  2. the more this, the less that
  3. the less this, the more that
  4. the less this, the less that

When writing a hypothesis sentence, it is important to remember this. The things you are studying must be measurable. These are called variables. That means, we have to be able to count or somehow quantify the variables we are trying to connect.

There are many ways to write a hypothesis. I am showing you just one sentence pattern. But, I like this hypothesis sentence pattern because it is easy for students to understand and use.

World History Video Lesson

This video shows the history of Earth. 200 years of change in 4 minutes. A unique presentation that will help build your vocabulary and listening skills. The video also shows you how to tell a great story with hypothesis sentences.

Write Your Answers

Watch the video and write your answers for these questions.

  1. What is the variable for each axis on the graph?
  2. How is each variable counted or measured?
  3. Can you write at least three hypothesis sentences using the data from the video?

Not sure about your answers?

Thank you for the video. I can understand it, but I can’t define or explain it in ratio form. Please define and answer your question for me, so I can better understand. Thank you again.
