Scientific Method

100

These are the 7 steps to the Scientific Method

1. State the Question

2. Collect Information

3. Form a Hypothesis

4. Test Hypothesis

5. Observe

6. Analyze Data

7. Draw a Conclusion 

200

These are the components that make up a Hypothesis

1. Testable

2. "If, Then" statement

3. Include the IV and DV

300

This is the variable that does not change unless changed by the scientist. 

Independent Variable

400

When you make a possible explanation for a set of observations you are formulating this. 

Hypothesis

500

A useful tool that may help scientists interpret data by revealing unexpected patterns.

Theory vs Law

100

This tells WHY something happens.

Scientific Theory

200

This tells WHAT happens in Nature. 

Scientific Law

300

True/False?- A modification of a theory or law must come with new evidence showing the previous version was not correct. 

TRUE

400

This scientific principle describes the way the world works. 

Scientific Law

500

Niels Bohr came up with a diagram to show the arrangement of electrons in an atom. This is an example of? 

Scientific Theory

Vocabulary

100

To arrange in a specific order or group by categories based on similarities

Classify

200

A statement that tells what an investigation showed, based on observations and data. 

Conclusion

300

The reproduction of a scientific investigation by another person to ensure accuracy

Replication

400

Observations that deal with descriptions that can be expressed in numbers

Quantitative Observation

500

A factor or condition in a scientific experiment that is purposefully kept the same

Controlled Variable

Observation Vs Inference

100

You use your 5 senses to describe something

observations

200

using past or prior knowledge to describe something

inference

300

observing

500

Making a statement or claim about what will happen in the future based on past experience or evidence is called (HINT: the answer is not observation or Inference)

Prediction

Toss up

100

When another scientist conducts an experiment using the same exact procedure as you used is an example of. 

Replication

200

When scientists create representation of a complex process, they are making...

 models

300

If a plant is put under a LED light, then it will grow faster than the plant in the UV light. What are the IV and DV of this hypothesis?

IV: Type of Light

DV: Plant Growth

400

Type of graph that shows how the responding variable changes in response to the manipulated variable in a trending form.

Line Graph

500

A line graph in which data points do not fall along a straight line

Nonlinear graph
