It’s week 6 of the adult evening class. Time to practice more critical thinking.
Pair Work Conversation (15)
- Have you ever eaten goat meat on Geumjeong Mountain?
- How many countries have you visited?
- Have you ever joined a temple stay program?
- Have you ever had a déjà vu experience?
- Have you ever slept in a strange place?
- Have you ever ridden an animal?
- What books have you been reading lately?
- Have you been doing anything fun or interesting since the summer?
This puzzle worksheet is slightly more advanced. It has many brain puzzles. Finding the answer is sometimes difficult, but explaining the answer is a little harder.
Hour 2 – Critical Thinking Activities
Review of class 2 weeks ago (10)
- What is an argument?
- What argument sentence pattern did we learn?
- What is the difference between correlation and causation?
- Give some examples of correlation with no cause and effect relationship.
- Remember the electric car TV commercial? What was the argument?
- Were those arguments true?
What’s a hypothesis? (20)
Part 1. Overview: Hypothesis Sentence Pattern (10 minutes)
A hypothesis is a sentence that tells us how two different variables are connected. There are many ways to write a hypothesis. This lessons focuses on one sentence pattern because it is easy to understand and use.
Here are some examples:
- The more water a plant gets, the faster the plant will grow.
- The more I study, the more I learn.
- The richer the country, the more waste is produced.
- The hotter the temperature, the more ice cream people buy.
When writing a hypothesis sentence, it is important to remember this:
- The things you are looking at must be measurable. These are called variables.
- That means, we have to be able to count or measure quantify the variables we are trying to connect.
Now look at the key words in the 4 hypothesis sentences above. How can we measure these different things?
Check this file for a few possible answers.
Part 2: Practice #1 (10 minutes)
Students apply their new found knowledge of the hypothesis sentence pattern. The task uses a famous video clip with Steve Jobs.
Here are the tasks:
- Watch the video 2 times.
- Summarize his main idea in one hypothesis.
Part 3: World History Video Summary (20)
This video shows the history of Earth. 200 years of change in 4 minutes. Here are the tasks.
Preview the vocabulary first. Then watch the video one time.
- life expectancy
- income per person
- Middle East
- industrial revolution
- Great Depression
- to catch up
Answer the questions in small groups.
- What is the variable on the X axis and Y axis?
- How is each variable measured?
- Summarize the entire video in one hypothesis sentence.
- The speaker doesn’t provide any evidence to prove his hypothesis. What specific variables might we look at to prove the hypothesis true or false.
