Understanding the Scientific Method

The video tutorial explains the scientific method, a systematic approach used by scientists to solve problems and understand the world. It begins with recognizing a problem, followed by making observations and forming inferences. A hypothesis is then formulated and tested through experiments. Data from these experiments are analyzed to draw conclusions. If the hypothesis is supported, it may lead to theory formation. The video emphasizes the importance of repeating experiments to ensure accuracy and acknowledges that scientific knowledge is always evolving.

What is the first step in the scientific method as demonstrated by Moby's plant problem?

• Recognizing the problem

• Analyzing data

• Forming a hypothesis

• Conducting an experiment

What observation was made about Moby's plant?

• The soil was dry and cracked

• The plant was growing rapidly

• The leaves were green and healthy

• The leaves were brown and falling off

What inference was made from the observations about the plant?

• The plant needs more sunlight

• The plant is being watered too much

• The plant is not getting enough water

• The plant needs fertilizer

What is a hypothesis in the context of the scientific method?

• A proven fact

• An unchangeable theory

• A testable explanation based on observations

• A random guess

In the experiment with the fig plants, what was the variable being tested?

• Type of pot

• Amount of sunlight

• Type of soil

• Amount of water

Which plant watering schedule resulted in the healthiest fig plant?

• Watered three times a week

• Watered once a week

• Watered every day

• No water at all

Why is it important to repeat experiments in the scientific method?

• To ensure the results are not due to chance

• To make the experiment more complex

• To increase the number of variables

• To make the hypothesis a fact

What happens if repeated experiments do not support the hypothesis?

• The hypothesis is rethought

• The hypothesis is discarded

• The hypothesis becomes a theory

• The hypothesis is ignored

What is a scientific theory?

• An untested idea

• An explanatory statement confirmed through repeated testing

• A hypothesis that has been proven once

• A random guess about a phenomenon

Why is there no such thing as a scientific fact?

• Because science is always changing

• Because facts are not important

• Because experiments are never accurate

• Because theories are more reliable
