An educated guess. What you think will happen in an experiment.
What is a hypothesis?
100
The variables that do not change, that you are in charge of keeping the same.
What are controls or controlled variables?
100
This is the answer to a problem.
What is a solution?
100
This variable was the amount of time it took for your Oreo to dissolve in a liquid.
What is the dependent variable?
100
When building a bridge you only have so much money and so many materials to use. These restrictions are called this.
What are constraints?
200
The first step of the scientific method.
What is a problem or a question?
200
The variable you are changing to test.
What is an independent variable?
200
These are the requirements that must be met in the engineering process.
What are criteria?
200
This variable was the type of liquid you used in your Oreo experiment.
What is an independent variable?
200
When designing a greenhouse for the moon you must make sure it is portable and have access to light, oxygen, and water. These are all examples of this.
What are criteria?
300
The steps you take in an experiment to solve a problem or answer a question.
What is a procedure or a process?
300
The variable you are measuring in an experiment.
What is a dependent variable?
300
These are the things that may hold the engineering process back. They could be problems or issues, like road blocks, that could effect your final product. Restrictions.
What are constraints?
300
This is the list of items needed to carry out an experiment or build a design.
What are materials?
300
This is a larger or smaller, scale version of a final product.
What is a model?
400
The information or measurements your gather during an experiment.
What is data?
400
The group in your experiment that does not change or receive something special.
What is the control group?
400
What is needed to accurately build something or collect data.
What is a measurement?
400
The steps you took to test your Oreo hypothesis?
What is a procedure or experiment?
400
This is proof of something.
What is evidence?
500
When you look over the data and observations you have made to help draw a conclusion.
What is analysis?
500
The group that is changed or tested in an experiment.
What is the experimental group?
500
To go back and redo, change, or improve a design.
What is a revision?
500
This is some time written as an "If...then...because..." statement.
What is a hypothesis?
500
Yes or no. Should you change more than one variable in an experiment.
