What is a hypothesis?

Back

A hypothesis is a testable statement or prediction that can be investigated through experimentation.

Front

What is the engineering process?

Back

The engineering process is a series of steps engineers follow to create solutions to a problem, which may include defining the problem, brainstorming, designing, testing, and refining solutions.

What is empirical evidence?

Back

Empirical evidence is data obtained by observation or experimentation, which can be used to support or refute a hypothesis.

What conclusion did Blazer Fresh reach after conducting his experiments?

Back

Five pieces of bread will prevent a dropped egg from breaking.

Front

Why is the engineering process considered non-linear?

Back

The engineering process is non-linear because it allows for revisiting previous steps based on new findings or challenges, leading to iterative improvements.

What does it mean to be 'stuck in the loop' in the engineering process?

Back

Being 'stuck in the loop' means that an engineer may repeatedly cycle through the same steps without making progress towards a solution.

What is the importance of testing a hypothesis?

Back

Testing a hypothesis is crucial because it allows scientists to validate or invalidate their predictions based on experimental data.

What role does data analysis play in the scientific method?

Back

Data analysis helps scientists interpret the results of their experiments, determine if the hypothesis is supported, and make informed conclusions.

What is the difference between a hypothesis and a theory?

Back

A hypothesis is a testable prediction, while a theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.
