The variable that the scientist changes on purpose is called the....
What is the INDEPENDENT VARIABLE.
What is the first step of the engineering design process?
What is IDENTIFY THE PROBLEM.
*Before you can do anything- you have to know WHAT THE PROBLEM IS!
TRUE OR FALE: A scientist was performing an experiment to determine if the amount of water made plant grow taller. An example of a constant for this experiment would be the type of soil used for all plants.
What is TRUE.
Remember- CONSTANTS are what you keep the SAME in order for the experiment to be FAIR. IT IS IMPORTANT for all soil types to be the SAME here to get an accurate measurement.
True or False: In an experiment testing to see which type of soda evaporates quicker, a constant would be the type of soda.
What is CRITERIA in the Engineering Design Process?
What the design MUST HAVE.
What is the INDEPENDENT variable in this experiment?
"Which type of metal, copper or aluminum, conducts heat faster?"
**The independent is WHAT you are CHANGING- the metal type is changing here!
An engineer is given a time limit of one month to design a compact cell phone that works under water and is durable.
What constraint will the engineer be facing when designing this phone?
What is the TIME FOR DESIGN.
Remember- CONSTRAINTS are limitations or boundaries the engineer has to work with. Since the engineer has a TIME LIMIT of one month- that is a CONSTRANT.
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid. Each plant has the same amount of sunlight, and soil. What is the independent variable?
What is the TYPE OF LIQUID.
You CHANGE the independent.
A working model or "test model" of the final product is called________________________.
What is a PROTOTYPE.
What is the EDP- ENGINEERING DESIGN PROCESS
What is the DEPENDENT variable in this experiment?
"Does eating breakfast improve test scores?"
What is THE GRADE ON THE TEST.
Remember- the DEPENDENT VARIABLE is the OUTCOME of the independent variable.
Mr. S set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. What is the dependent variable?
The variable that is observed or measured is known as the...
What is the DEPENDENT VARIABLE.
This is WHAT YOU WANT TO KNOW.
Leslie conducted an experiment testing plant growth under red, blue, and yellow lights. Her hypothesis is, if plants are grown under different colored lights, then the plants under red lights will have the most growth. What is the INDEPENDENT VARIABLE?
What is.. the DIFFERENT COLORED LIGHTS.
-This is what you are CHANGING IN THE EXPERIMENT.
I want to know which substance (water, sugar, salt) will melt an ice cube the fastest- what is the INDEPENDENT VARIABLE here?
What is the TYPE OF SUBSTANCE.
A student is planning an experiment to find out how the height from which a ball is dropped affects how high the ball
bounces. The dependent variable is the _____________.
What step of the engineering design process follows creating the prototype and involves seeing if the prototype works correctly?
What is TESTING/EVALUATE
Sarah has 4 potted plants. She wants to see if the plants would grow more if she adds vinegar to one, oil to one, sugar water to one, and regular water to one.
What is the dependent variable in this experiment?
What is THE AMOUNT OF PLANT GROWTH.
Dependent- you are OBSERVING how much plant growth there is. This is the OUTCOME of your experiment!
Based on the hypothesis below what is the dependent variable?
-If students attend more lectures than the students will have better exam results.
What is- THE EXAM RESULTS
Dependent- is what you are MEASURING.
What is it called in the Scientific Method Process when you make an EDUCATED GUESS about your question.
What is called THE HYPOTHESIS
What is the INDEPENDENT variable in this experiment?
"Will fish school more if a predator is present?"
What is IF THERE IS A PREDATOR OR NOT.
Mr. Shell set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. Identify the independent variable.
Independent- what you are CHANGING. The mass of the ball would be changed here.
What is the correct order of steps to follow in the engineering design process? What is the correct order of steps to follow in the engineering design process?
1) Identify a NEED/Problem
2) Research/Brainstorm SOLUTIONS.
3)Build and TEST a PROTOTYPE.
4) Report the RESULTS.
Remember- before you can do ANYTHING- the problem has to be KNOWN.
Dianne tested various brands of laundry detergent to see which one removes stains the best. Which of the following variables should Diane have kept constant during her experiment?
What is: THE AMOUNT OF DETERGENT USED.
What would the independent variable be in an experiment test which type of paper airplane goes the furthest?
What is the TYPE OF PAPER USED.
What you are changing!!
