Non-testable question
Questions that cannot be answered by direct observations or by evidence gathered through experimental inquiries
Quantitative
Data that can be counted or measured in numerical values
Qualitative
Non numerical data like text, video, or audio to understand concepts, opinions, or experiences
Trials

Observations
Using the senses to gather information about an object or event.

Models in science
A scientific model is where scientists represent something in the real world in a way that makes it easier to understand, or make predictions.
Analogy
Analogies are a comparison of the similarities between two concepts.
Prototype
A prototype is an original model constructed to include all the technical characteristics and performances of the new product.
Hypothesis
A hypothesis is a concept or idea that you test through research and experiments.
Variable
Variables are anything that can change or be changed within an experiment.
Procedure
A procedure is a listing of what specifically was done in the laboratory during an experiment, step by step.
Precision
Precision refers to how close measurements of the same item are to each other.
Accuracy
Accuracy refers to how close a measurement is to the true or accepted value.
Scientific method
The scientific method is the process of objectively establishing facts through testing and experimentation.
control
A control is an element that remains unchanged or unaffected by other variables. It’s used as a benchmark or a point of comparison against which other test results are measured.
