The standard used for comparison of test results in an experiment

Control

The standard used for comparison of test results in an experiment. Control. In an experiment, a control is a part that does not change, so scientists can see what effect the changes have.

Information gathered through observation

Data

Information gathered through observation. Data. Data is the facts or details collected to help us understand something.

Testing a hypothesis by collecting data in controlled conditions

Experiment

"Testing a hypothesis by collecting data in controlled conditions. Experiment. In simple terms, an experiment is a procedure where we test ideas by trying things out and observing what happens."

A possible explanation or answer to a scientific question

Hypothesis

A possible explanation or answer to a scientific question. Hypothesis. A hypothesis is an educated guess that scientists test to see if it's true.

A representation of an object or system

Model

A representation of an object or system. Model. In Grade 7 science, a model is a simple way to show how something works or looks without needing the real thing.

The use of scientific observations to solve practical problems

Technology

The use of scientific observations to solve practical problems. Technology. Technology is anything we create to make tasks easier or solve everyday problems.

Explanation of observations supported by evidence

Theory

An explanation of observations supported by evidence is called a theory. In simple terms, a theory is a well-tested idea that helps us understand and predict how things work in the world.

The factor that can change in an experiment

Variable

The factor that can change in an experiment variable. In simple terms, a variable is something in an experiment that can be changed or controlled.
