Scientific Method
A step-by-step process used by scientists to investigate questions, which includes observation, forming a hypothesis, experimentation, and drawing conclusions.
Hypothesis
A proposed explanation or an educated guess made on the basis of limited evidence as a starting point for further investigation.
Data Collection and Analysis
The process of gathering accurate measurements and observations during an experiment to test whether the hypothesis is correct.
Controlled Experiment
An experiment in which all variables are kept constant except for the one being tested to ensure reliable results.
Safety in Science

Frequently Asked Questions
What is the very first step in any scientific investigation?
The first step is making careful observations about the surrounding world, which leads to asking a specific scientific question.
Why is a controlled experiment important?
A controlled experiment ensures that only one variable is changed at a time, so you can clearly see the effect of that specific variable on the outcome.
How is a hypothesis different from a theory?
A hypothesis is an educated guess before testing, whereas a scientific theory is a well-substantiated explanation backed by a large body of repeated experimental evidence.
