Qualitative
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. In this investigation, the independent variable is ...

data
Conclusions based on observations
Inferences
The act of seeing an object or event and noting the physical change
observations
A hypothesis must have 2 components.
IF......THEN
Daniel was investigating how fast it took mice to react to different sounds. Identify the independent variable.
different sounds
An experiment has 10 plants growing in sunlight and 10 plants growing in red light. The plant height is measured after one month. What is the dependent variable in this experiment?
The plant Height
A prediction or possible answer to a question
hypothesis
The factor that is intentionally varied by the exerimenter
Independent variable
Catherine is testing which soil will help grass grow the tallest. The height of the grown grass is the __ variable.
dependent
"If plants are exposed to sunlight, then they will grow taller."
What part of the scientific method is this an example of?
Hypothesis
Mr. Wells is probably not in school today because his is sick. Is this a Qualitative Observation, Quantitative Observation, or an Inference
Inference
Shows relationships between independent and dependent variables
Data
The factor that might change as a result of changes made (the outcome).
Dependent variable
What would the INDEPENDENT variable be in an experiment testing which paper airplane design goes furthest?
the paper airplane design
Which step? "I was right!: Touching the cheese makes the cheese moldy."
conclusion
When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. The fact that we kept the light, plant, and water the same in each experiment are examples of ____________.
Constant
