Scientific Method Steps
The outcome or results of an experiment
The Dependant Variable
Describe a Hypothesis
An educated guess about what will happen in an experiment (if, then)
What are two types of observations?
Qualitative and Quantitative
Controlled Variable
What is a variable?
Factors that change in an experiment
This step involves testing a hypothesis
An experiment
What Must Every Hypthesis Have?
An "if, then" statement
What is a Qualitative Observation?
Qualitative is a describable variable (color, taste, touch, sight)

WONDERFUL CHOICE!
Define Independent and Dependant Variable
Independent Variable: The thing you can change in an experiment (manipulated variable)
Dependant Variable: The thing that is being measured in an experiment (responding variable)
What is a Quantitative Observation?
A quantitative observation is number-based, countable, or measurable.
Name 4 things that must be done prior to an experiment. (100 extra points, if you can name what not to wear during an experiment)
1: Wash Hands
2: Tie Hair Back
3: Wear Proper Clothing (BONUS: no loose clothes, open-toed shoes, or long sleeves)
4: Wear Safety Googles, And Or Gloves
An experiment in which only one variable is manipulated at a time is called a ________ (fill in the blank)
Controlled Experiment
Who invented the Scientific Method?
A physicist named Galileo Galilee
A Hypothesis must be ___________ (fill in the blank)
Testable
Think about a flowering plant. What are 2 things you can measure, and 2 things you can observe? (cannot be the same answer twice)
Measure: The height and Thickness
Observe: The feeling, The Looks, Or even the Taste
In order to have a controlled experiment (aside from the independent variable) must be _______ (fill in the blank)
Exactly the same

THAT MUST SUCK
Name all six steps of the Scientific Method
1- State the Question
2- Collect informationn
3- Form a Hypothesis
4- Test the Hypothesis
5- Record and Study Data
6- Draw a Conclusion
What is this hypothesis missing?
I eat 10 apples and then drink a glass of water.
It is missing an "if, then" statement
BONUS: It cannot be an experiment, because all it states is that you eat 10 apples and drink a glass of water.
Can you name 5 types of observations?
Structured Observation, Unstructured Observation, Covert Observation, Overt Observation, and Participant Observation

GREAT PICK!!
What is the difference between scientific law and theory?
Law- describes an observed pattern in nature (laws cannot change)
Theory- explains why something is happening in nature (can change)
