1. Scientific Method Steps
1. Problem/Question- what question does the researcher want answered? The question must be testable.
2. Research- you must gather information from online sources, books, printed material, other people, and prior knowledge
3. Hypothesis- a possible explanation for observations that relate to a scientific question; must be testable; must include the words if, then, and because
4. Conduct an Experiment- complete an experiment to test hypothesis; the experiment includes procedures and can involve observations (5 senses); uses 3 variables- independent, dependent, and control
5. Record Results- record the data gathered from an experiment in a table, chart, or graph
6. Conclusion- communicate results and explain possible errors that occurred

2. Qualitative vs. Quantitative
Qualitative- describes data and does NOT include numbers; observations (5 senses)
Examples: color, texture, smell, sight, shape, taste, size
Quantitative-data that includes NUMBERS
Examples: height, length, width, number,

3. Reflection Give 3 examples of qualitative data 1. 2. 3.
Give 3 examples of quantitative data

4. Which type of soap will produce the largest bubble?

5. If the ((Hand or dish soap or both) is used, then it will create a (bigger or smaller) bubble, because ___________________.

6. Bubble Bonanza

7. 3 types of variables

8. Control Variables/Group
Control Variables- variables that stay the SAME; there can be more than one
Control Group- serves as a method of comparison; does NOT receive the test subject
Example: measure the effect of different types liquids on plant growth.
Liquids: water, diet coke, lemonade, Coca-Cola, and tea

9. Independent Variables
Independent- variable that is CHANGED in an experiment; manipulated
Ex. Measuring the effect of different liquids on plant growth: independent- type of liquid

10. Dependent Variables Dependent- variable that is MEASURED
Ex. Measuring the effect of different liquids on plant growth: Dependent- plant growth

11. DRY MIX D- Dependent R-Responding Y-Y-Axis M-Manipulated I-Independent
X- X-Axis

12. Observation vs. inference
Observations are:
1. Factual
2. objective
3. gathered using 5 senses
4. free of opinion/ideas
Inferences are:
1. conclusion/assumption
2. based on observations
3. subjective
4. formed from an opinion- previous knowledge
Ex. 5 plants- watered with: water, Gatorade, coca-cola, diet coke, lemonade
