Unit Test: Biology Test

Give an example of a hypothesis in the correct format: (If then format)

Independent variable- Cause/Change

Dependent variable- Effect/Response

Observation- Description of something you can see, smell, touch, taste, hear (NOT an opinion)

Experimental Group- Groups that are being tested

Control Group- Group used for comparison with your experimental groups.  

Qualitative- Describes qualities 

Quantitative- Uses numbers to measure something

Hypothesis- A testable prediction based on observations (more than a guess!!) that describes a cause-and-effect relationship between variables

Principle- a statement based on repeated experimental observational 

Inference- A guess about an object or outcome based on your observations

Accuracy-How close your measurement is to the correct/accepted value 

Precision-How close your measurement is to each other

Constants- Remain unchanged throughout the experiment

What is the significance of having data that is both accurate and precise? Accuracy helps you know how close your data was to the correct answer and precision helps you compare data to each other.

Steps of conducting an experiment or designing one? Define your variables,  

Give an example of a scientific investigation design, with appropriate constants and variables (IV and DV)   

Conduct a scientific experiment using appropriate laboratory equipment. Put your hair up, goggles, clear area, & gloves.

How to identify variables when given the description of a scientific investigation.  Dv- this is the changes as the result of the independent Iv- this variable isn’t changed by any by any other variables
