​The Nature of Science Vocabulary

• Open-mindedness - will accept surprise results

Multiple Choice

• Repeatability

• Tentativeness

• Open-mindedness

• Simplicity

​The Nature of Science Vocabulary

• Simplicity - simplest idea is accepted until we learn otherwise.

Multiple Choice

Scientific studies are shared in papers, journals and magazines.

• Repeatability

• Causality

• Repeatability

• Tentativeness

• Open-mindedness

• Comprehensibility

​The Nature of Science Vocabulary

• Tentativeness - change an understanding when we learn more.

Multiple Choice

What is the correct order of the Scientific Method?

• observation, problem, hypothesis, experiment, conclusion

• observation, experiment, 

  hypothesis, problem,

  conclusion

• observation, problem, 

  experiment, hypothesis, 

  conclusion

​Steps of the Scientific Method(s)

1. ​OBSERVE (use senses)

2. ​PROBLEM (question)

3. ​HYPOTHESIS (if, then, because)

4. ​EXPERIMENT (procedure, data)

5. ​CONCLUSION (what you learn)

Multiple Choice

The portion of the scientific method that deals with gathering and organizing data is:

• Observation

• Problem

• Hypothesis

• Experiment

• Conclusion

Multiple Choice

The portion of the scientific method that deals with supporting or not supporting the hypothesis with specific data is:

• Observation

• Problem

• Hypothesis

• Experiment

• Conclusion

Multiple Choice

What part of the hypothesis explains WHY a certain prediction was made?

• If

• Then

• Because

​Hypotheses

• ​IF there is a relationship between A and B

• ​THEN B should increase as A decreases

• ​BECAUSE I have observed this occur in other situations.

Multiple Choice

• Qualitative

• Quantitative

• Hypothesis

• Conclusion

Multiple Choice

• Qualitative

• Quantitative

• Hypothesis

• Conclusion

Multiple Choice

Lilacs smelled the sweetest of all the flowers.

• Qualitative

• Quantitative

• Hypothesis

• Conclusion

Observations & Data

• QUANTITATIVE - a "quantity" (amount, #) of mangos

• ​QUALITATIVE - describes the "quality" of mangos (color, odor, texture)

Multiple Choice

An outlier should be recorded in a data table, even if it isn't used to calculated an average.

• True

• False

Multiple Choice

Measuring wrong with a ruler is an acceptable error.

• True

• False

Multiple Choice

You keep everything that could affect the results the same for each trial.  This is called:

• Keeping all other variables controlled (constant)

• Control Group

• Experimental Group(s)

• Dependent Variable

Multiple Choice

You want to know if darkness affects plant growth, so you put plants in a dark closet.

• Keeping all other variables controlled (constant)

• Control Group

• Experimental Group(s)

• Dependent Variable

Multiple Choice

The measurements of the results are the:

• Keeping all other variables controlled (constant)

• Control Group

• Experimental Group(s)

• Dependent Variable

Multiple Choice

The title of a graph includes the dependent variable (unit) vs. the independent variable (unit)

• True

• False

Past Information to Note:

1. Measure one place smaller than lines on tool.

2. ​Round up if next number over is 5 or more.

3. ​Average by adding all then divide by # of data points.

4. ​Find percent by part over whole (POW) x 100

5. Titles (D vs. I) on graphs and tables

6. Dep. on X (horizontal) and Indep. on Y (vertical)

7. ​Density = mass (g) / volume (mL or cm³)

8. ​Density of water is 1.00 g/mL - if object greater, then it sinks

9. ​Factor label uses a fraction to go from one unit to another
