🎯 Class Objective:
The student proposes what the concept of the Scientific Method is and verifies their prior knowledge using the formal definition of the Scientific Method.
The student differentiates among observations, facts, hypotheses, laws, theories, and principles.

📘 What is the Scientific Method?
📘 What is the Scientific Method?
The Scientific Method is a systematic process used to investigate questions, test ideas, and explain natural phenomena using evidence.
Observation
Observation
We notice something happening using our senses.
Question about the phenomena
Question about the phenomena
We ask why or how something happens.
Hypothesis
Hypothesis
We propose a possible explanation that can be tested.
Experiment
Experiment
We design a test to check if the hypothesis is correct.
Results
Results
We collect and analyze the data from the experiment.
Conclusion
Conclusion
We verify if the hypothesis was correct or not.
🪂 Free Fall and Air Resistance
🪂 Free Fall and Air Resistance
When you drop a notebook and a sheet of paper at the same time, the notebook reaches the ground first.
However, when you place the paper on top of the notebook and drop them together, they fall at the same speed.
Why does this happen? Is gravity acting differently on each object?
The difference happens because of air resistance. In a vacuum, both objects fall at the same rate.
