Thinking in Causation - Level 2 - Testing Causes

The video tutorial explores the concept of cause and effect in scientific investigations. It emphasizes the importance of defining a system and developing fair tests to identify causes of observed effects. Through examples like a ramp and ball system and a faulty flashlight, the video demonstrates how to brainstorm possible causes and test them systematically. The tutorial encourages learners to apply these methods to real-world scenarios, such as testing materials for cooling or heating and plant growth.

What is the first step in investigating cause and effect according to the video?

• Identifying the effect

• Developing a test

• Defining the system

• Brainstorming possible causes

In the ramp and ball experiment, what is identified as the effect?

• The ramp's angle

• The unpredictable motion

• The ball's color

• The ball's speed

Why is it important to test one possible cause at a time in an experiment?

• To identify the specific cause

• To ensure accuracy

• To use fewer resources

• To save time

What is the effect observed in the faulty flashlight system?

• The flashlight flickers

• The flashlight changes color

• The flashlight does not turn on

• The flashlight is too bright

Which of the following is NOT a possible cause for the faulty flashlight?

• Battery direction

• Battery charge

• Broken lamp

• Incorrect bulb type

What is the purpose of developing fair tests in scientific investigations?

• To confirm existing theories

• To identify the correct cause of an effect

• To eliminate all possible causes

• To simplify the experiment

What is encouraged as the best way to learn about cause and effect?

• Watching videos

• Trying out experiments

• Reading textbooks

• Listening to lectures
