Scientific Method and Engineering Design Cycle

The summary at the end of an experiment that explains the results is... 

• conclusion
• procedures
• materials
• responding variable

A testable prediction about a scientific investigation is a(n)

• Question
• Observation
• Hypothesis
• Experiment

The process of obtaining information by using the senses is called a/an

• Conclusion

• Observation

• Inquiry

• Scientific method

What is the first step in the scientific method?

• Make an observation --> Question
• Design and conduct an experiment
• Make an hypothesis
• Share your results

It is a forecast of future events based on past observation. And sometimes interchangeable to hypothesis.

• hypothesis

• fair testing

• prediction

• experiment

Scientists create both scientific theories and scientific laws as they make observations and conduct experiments about the natural world. Which of the following statements most accurately compares the difference between scientific theories and scientific laws

• science laws are based on evidence while science theories are not

• science theories involve only biology, while laws involve all types of science

• science theories involve mathematical equations, while science laws are based on observations

• science theories are ideas that explain natural events, while science laws predict what will happen in a natural event.

According to the picture, which of these is an inference, rather than an observation?

• This animal has hair.

• This animal has a tail.

• This animal is arching its back.

• This animal is frightened.

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check
