M-STEP Science Inquiry & Data Interpretation

Question 1

What is the first step in the scientific method?

Accepted Answer

Make an observation

Answer

The scientific method typically begins with making an observation about the natural world. This initial observation often leads to questions that scientists seek to answer through further investigation. Forming a hypothesis, conducting experiments, and drawing conclusions follow this initial step.

Question 2

Why is it important to repeat experiments?

Accepted Answer

To verify results and ensure reliability

Answer

Repeating experiments, also known as replication, is crucial for verifying the consistency and reliability of results. It helps ensure that the findings are not due to random chance or experimental error, thereby strengthening the validity of the scientific conclusions.

Question 3

What is a controlled variable?

Accepted Answer

The variable kept the same throughout the experiment

Answer

A controlled variable is an element that an experimenter keeps constant and unchanged throughout an experiment. This ensures that any observed changes in the dependent variable can be attributed solely to the manipulation of the independent variable, maintaining the fairness and accuracy of the test.

Question 4

What is the purpose of a hypothesis?

Accepted Answer

To make a testable prediction

Answer

A hypothesis is a testable prediction or an educated guess that proposes an explanation for an observation. It serves as a starting point for scientific investigation, guiding the design of experiments to either support or refute the proposed explanation.

Question 5

Why is data interpretation crucial in science?

Accepted Answer

It allows scientists to understand experiment outcomes

Answer

Data interpretation is crucial because it involves analyzing the collected information to identify patterns, trends, and relationships. This process allows scientists to understand the outcomes of their experiments, draw meaningful conclusions, and determine whether their hypothesis was supported.
