Study Notes

Scientific Investigation

A process of finding answers to questions by using research methods
Includes steps such as identifying the aim or problem, planning materials and equipment, writing procedures, recording results, and drawing conclusions
Requires the use of a hypothesis, which is a proposed explanation based on limited evidence that is tested during the investigation
Variables are factors that are changed or manipulated during the experiment to test the hypothesis

Applying the Scientific Method

Using the scientific method in everyday scenarios helps find solutions logically and systematically, reducing frustration and improving outcomes.
The scientific method ensures medical decisions are based on evidence, increasing chances of treatment success
The scientific method helps understand complex environmental issues and develop strategies to protect ecosystems.

Scientific Attitudes

Important for scientific investigation
Include curiosity, objectivity, open-mindedness, and cooperation

Steps of a Scientific Investigation

Identifying the problem: Defining the question being investigated.
Formulating a hypothesis: Developing a testable explanation for the problem.
Testing the hypothesis: Collecting data to support or refute the hypothesis.
Drawing conclusions: Analyzing the data collected and determining whether the hypothesis is supported.

Importance of the Scientific Method

Ensures findings are based on observable evidence.
Allows for replication and validation of results by other scientists.
Helps to identify and eliminate bias.

The Scientific Method in Real-Life Scenarios

Healthcare: Determining the effectiveness of new treatments.
Environmental science: Understanding climate change and finding solutions for pollution.
Engineering: Developing new technologies and solving problems related to infrastructure

Lab Activity

Includes stating objectives, discussing procedures, and writing a graphic organizer
Activity named "INVESTIGARE"
Focuses on the scientific method
Students perform the actual lab activity and answer the lab sheet

Lesson Goals

Internalize scientific attitudes by performing activities
Make accurate measurements using standard units for physical quantities
Organize collected data when carrying out scientific investigations

Example Scientific Investigation

Example: Alex has a high-carbohydrate diet and experiences symptoms such as excessive thirst, frequent urination, fatigue, and blurred vision.
This investigation aims to determine if a diet high in carbohydrates and sugary foods can lead to elevated blood sugar levels and associated symptoms
