Nature Of Science 1
An idea claims that a certain crystal can improve a person's ability to concentrate, but there is no reliable scientific evidence supporting the claim. Science or pseudoscience?
Pseudoscience
This is information gathered using your senses or scientific tools.
Observation
What is PseudoScience
Science based on beliefs with no evidence
investigation
My experiment proved that my hypothesis is 100% correct. Since I got the result I expected, no other scientist needs to repeat my experiment. True or false and why?
false, scientific work must always be repeated by other scientists.
a statement that describes an observable occurrence in nature that appears to always be true and someone has to see it.
What is a Scientific Law
An educated guess of what will happen in an experiment
hypothesis
Explain what Quantitative Data is.
Data that uses numbers or measurements.
measurments or observations collected and recorded in an experiment or investigation are known as
data
This word describes scientific knowledge that is supported by evidence and can remain accepted for a long time.
Durable
A scientist repeats an investigation several times and gets similar results. What does this help show?
accurate / reliable
Forming a hypothesis based on previous knowledge.
prediction.
What is the major difference between a scientific theory and a scientific law?
Theory describes/ explain and a law predicts
To examine something and separate it into parts and study the similarities is to
Analyze
This word describes scientific knowledge that can be changed or improved when new evidence is discovered.
Tentative
Why is it important for scientists to share their methods and evidence with other scientists?
So other scientists can evaluate, repeat, and verify the investigation.
Drawing a counclusion based on evidence and reasoning
Inference
This is a well-supported explanation of a natural phenomenon based on lots of evidence.
Scientific theory
Using one or more of you senses to gather information is called
observing
Data that involves numbers and measurements, such as the length of a plant growing 15cm
Quantative Data
Scientists conduct controlled experiments to test whether a new medicine works and publish their evidence for other scientists to evaluate. Science or pseudoscience? why?
Science, it was done in a controlled experiment
Summarize the results and state whether the hypothesis was correct
conclusion
Rayne recorded her observation that shows blue litmus paper changing to red when it was placed an acid. what type of data is this classified as?
Qualitative data
This is a testable explanation or prediction based on observations and prior knowledge.
Hypothesis
Scientists have collected evidence supporting an explanation for many years. However, they continue to test it because new evidence could lead to changes. Which two characteristics of science does this demonstrate?
Durable and tetative
