| The Steps | ||
| #1 | What 2 words must be in a hypothesis? |
If and Then |
| #2 | Define Scientific Inquiry. |
General steps that scientists follow to solve problems. |
| #3 | A hypothesis must be _______. |
Testable |
| #4 | How do you organize collected data? |
Put it into a table or a chart. |
| #5 | What is a conclusion? |
A summary of what you have learned from the experiment |
| Scientific Theory & Law | ||
| #1 | What’s the difference between scientific law and theory? |
The law describes an observed pattern in nature and the theory explains why something is happening in nature. Laws cannot change. Theories can. |
| #2 | The scientific _______ can change and the scientific ______ can not change? |
The scientific theory can change and the scientific law can not change. |
| #3 | Define Scientific Inquiry |
Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence they gather. |
| #4 | What is a scientific law? |
The scientific law describes an observed pattern in nature without attempting to explain it. |
| #5 | What is a scientific theory? |
A scientific theory is a well tested explanation for a range of observations or experimental results. |
| Design an Experiment | ||
| #1 | What is a variable? |
Factors that change in an experiment |
| #2 | What is the difference between an independent and dependent variable? |
The independent variable is purposely changed and the dependent variable changes because of the independent variable |
| #3 | What is a controlled experiment? |
An experiment in which only one variable is manipulated at a time |
| #4 | What is Communicating? |
The sharing of ideas and experimental findings with others through writing and speaking. |
| #5 | In order to have a controlled experiment the variables (aside from the independent variable) must be _____________ |
Exactly the same |
| Observation, Inference and Prediction | ||
| #1 | Define an observation. |
Observing means using one or more of your senses to gather information. |
| #2 | What are 2 types of observations? |
Quantitative and Qualitative Observations |
| #3 | Define an inference. |
An interpretation based on observations and prior knowledge. |
| #4 | Define a prediction. |
A prediction is a forecast on what will happen in the future based on past experience. |
| #5 | How do observations, inferences and predictions go together? |
After you observe something, you can then make an inference on what you saw. Based on your observation and inference you can then make a prediction on what will happen. |
| Grab Bag | ||
| #1 | What is data? |
The facts, figures, and other evidence gathered through observations |
| #2 | An experiment in which only one variable is manipulated at a time is called a _______ |
Controlled Experiment |
| #3 | What is a manipulated (independent) variable? |
A variable that is purposely changed |
| #4 | Is this statement an observation, inference or prediction? "The cat is ill" |
Inference: You cannot observe the cat being ill, you can observe the cat sleeping a lot or thowing up, but you would then infer that the cat is ill based on these observations. |
| #5 | An ______ is a statement that describes how to measure a particular variable or define a term. |
An operational definition |
| Final Question | |
State the Scientific Method steps in order. |
1: Pose a Question 2: Develop a Hypothesis 3: Design an Experiment 4: Collect and Interpret Data 5: Draw Conclusions 6: Communicate |
