Scientific Method

The scientific method is a systematic approach used by scientists to investigate phenomena, acquire new knowledge, or refine existing knowledge. It involves a series of steps aimed at formulating hypotheses, testing them through experiments or observations, and drawing conclusions based on empirical evidence.

Which of followings are considered to be the scientific method?

• Question Formulation

• Hypothesis

• Prediction

• Experimentation or Observation

• All of above

Observation: Scientists observe and notice some aspect of the natural world, leading them to ask questions about it.

Which of the followings is an Observation example?

• I watched a baby boy playing a toy at front yard.

• I assigned a baby boy to play a toy at front yard.

• I discussed a baby boy how to play a toy

• I commanded a baby boy go out and play a toy at the front yard.

Question Formulation: Based on observations, scientists formulate a question or a problem to be addressed.

Which of followings of a question is a question formulation

• Do you like to travel?

• What are some of your favorite travel destinations, and why do you enjoy visiting them?

• Why are you traveling?

• What is a travel destination do you want to see?

• What is a city you want to see?

Hypothesis: A hypothesis is a tentative explanation or prediction that can be tested through experimentation or observation. It's usually formulated as an "if-then" statement, suggesting a cause-and-effect relationship.

Which of the following statement is considered a Hypothesis Statement?

• If you have money, where are you going to go?

• Our school will be closed tomorrow because of a weekend.

• If it is a rain, I'' stay a home.

• If plants are treated with fertilizer containing nitrogen, phosphorus, and potassium, then they will exhibit greater growth in terms of height and foliage compared to plants that receive no fertilizer.

Prediction: From the hypothesis, scientists make predictions about the outcome of experiments or observations if the hypothesis is correct.

Based on the kinetic theory of gases, it is predicted that as temperature increases, the rate of chemical reaction will also increase.

• it is an hypothesis prediction because it predict what is the kinetic theory of gases in the future.

• it is an hypothesis prediction because it predict what is the kinetic theory of gases in the future.

• it is an hypothesis prediction because of the rate of chemical reaction

• it is an hypothesis prediction because it predict what is the kinetic theory of gases in the future.

Experimentation or Observation: Scientists design and conduct experiments or make observations to test the predictions and gather data.

If plants are exposed to higher light intensity, then they will exhibit increased growth compared to plants exposed to lower light intensity.

• If it is fact, plants exposed to higher light intensity should show greater growth in terms of height and leaf number compared to those exposed to lower light intensity.

• If the hypothesis is correct, plants exposed to higher light intensity should show greater growth in terms of height and leaf number compared to those exposed to lower light intensity.

• If it is an opinion, plants exposed to higher light intensity should show greater growth in terms of height and leaf number compared to those exposed to lower light intensity.

• If it is a story, plants exposed to higher light intensity should show greater growth in terms of height and leaf number compared to those exposed to lower light intensity.

What is the first step in the scientific method?

• Make an observation --> Question
• Design and conduct an experiment
• Make an hypothesis
• Share your results

A testable prediction about a scientific investigation is a(n)

• Question
• Observation
• Hypothesis
• Experiment

Stephen predicted that seeds would start to grow faster if an electric current traveled through the soil in which they were planted.

• recognize a problem
• test the hypothesis with an experiment
• form a hypothesis
• draw conclusions
