Experimental Design
Usually written in "Does the (IV) affect the (DV) format?
What is the scientific question?
What are units?
Data that uses specific quantities or numbers
What is quantitative data?
The variable scientists change or manipulate on purpose to determine if it has a specific effect.
What is the independent variable?
The process used by plants to convert solar energy into stored chemical energy in the form of organic compounds and sugars.
what is photosynthesis?
A predicted outcome, sometimes written in "If (the IV) then (the DV)" format.
What is the hypothesis?
This is done to increase the accuracy of data in any experiment involving more than one trial.
What is calculating the average?
Data that does not use numbers, but rather relies on properties like roundness or aroma.
What is qualitative data?
A variable that must remain the same in all of the groups within a controlled experiment.
What is a controlled variable?
The human action causing a massive amount of atmospheric carbon to build up over time.
What is the use of fossil fuels?
A collection of pieces of information recorded using various sensing parts of the body.
What are observations?
This process involves other scientists critiquing and weighing in on the accuracy or quality of a previously completed experiment.
What is peer review?
This series of boxes is arranged in various ways to showcase the dependent variable compared to the independent variable.
What is a table or chart?
The group within an experiment that is compared to the experimental groups in order to determine if the independent variable is causing an effect on the dependent variable.
What is the control (control group)?
This agricultural technique causes stored carbon in the soil to escape into the air.
What is tilling?
An idea based on observations and prior knowledge that has not been proven yet.
What is an inference?
This can be done to increase the accuracy of data in a controlled experiment.
What is repeat the experiment?
This type of data representation makes it easier to spot trends or predict outcomes of additional data by visually displaying the independent and dependent variables on opposing axes.
What is a graph?
In a lab to find out how high different tennis balls bounce, the height the ball bounces would be this.
What is the dependent variable?
This type of agriculture considers the earth and the products in order to create sustainable systems that deliver "Good Food".
What is regenerative farming?
Data driven statement that addresses the accuracy of the hypothesis in the experiment.
What is the conclusion?
This term refers to the number of data points collected in any experiment. Typically, the larger it is the more valid the data.
What is the sample size?
These one off data points are usually drastically higher or lower than the average data and usually signify an issue, mistake or anomaly.
What are outliers?
The independent variable in a lab designed by a student to determine the effect of ocean water acidity on the number of algae per cubic meter of ocean water.
What is the ocean water pH?
What are stomata?
