Slide 1 - Diapositive
Cet élément n'a pas d'instructions
Learning Objective
At the end of the lesson, you will be able to identify the steps of the scientific method, explain them, and apply them with examples. .
Slide 2 - Diapositive
Provide an overview of the lesson's objective and what students will achieve at the end of the lesson.
What is the Scientific Method?
The scientific method is a systematic approach to discovering the unknown through observation, hypothesis, prediction, experimentation, and analysis.
Slide 3 - Diapositive
Introduce the scientific method and its purpose.
Step 1: Observation
Observation is the act of gathering information through the senses and noting facts or data.
Slide 4 - Diapositive
Explain the first step in the scientific method and provide an example.
Step 2: Hypothesis
A hypothesis is a proposed explanation for an observation or phenomenon based on limited evidence or data.
Slide 5 - Diapositive
Explain the second step in the scientific method and provide an example.
Step 3: Prediction
A prediction is a statement that describes a future outcome or result based on a hypothesis.
Slide 6 - Diapositive
Explain the third step in the scientific method and provide an example.
Step 4: Experimentation
Experimentation involves testing the hypothesis by manipulating one or more variables and observing the outcome.
Slide 7 - Diapositive
Explain the fourth step in the scientific method and provide an example.
Step 5: Analysis
Analysis involves interpreting the data collected from the experiment to determine whether the hypothesis was supported or rejected.
Slide 8 - Diapositive
Explain the fifth step in the scientific method and provide an example.
Example: The Vinegar and Baking Soda Experiment
This experiment involves mixing vinegar and baking soda to create a chemical reaction. The observation is the fizzing and bubbling that occurs. The hypothesis is that the reaction is caused by the mixing of an acid (vinegar) and a base (baking soda). The prediction is that the reaction will produce carbon dioxide gas. The experiment involves mixing vinegar and baking soda in a container and observing the reaction. The analysis involves measuring the amount of carbon dioxide gas produced and comparing it to the prediction.
Slide 9 - Diapositive
Provide an example of the scientific method in action using the vinegar and baking soda experiment.

Real-World Applications
The scientific method is used in various fields such as biology, chemistry, physics, and engineering to investigate and solve complex problems.
Slide 15 - Diapositive
Explain the real-world applications of the scientific method and provide examples.
Example: The Evolution of the Peppered Moth
The case of the peppered moth is an example of the scientific method in action. The observation was the change in the moth's color from light to dark. The hypothesis was that the change was due to natural selection. The prediction was that the population of darker moths would increase over time. The experiment involved collecting and counting the number of light and dark moths. The analysis involved comparing the data to the prediction and determining that the hypothesis was supported.
Slide 16 - Diapositive
Provide an example of the scientific method in action using the evolution of the peppered moth.

Write down 3 things you learned in this lesson.
Slide 22 - Question ouverte
Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.
Slide 23 - Question ouverte
Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
Ask 1 question about something you haven't quite understood yet.
Slide 24 - Question ouverte
The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
