This is an example: Is light required for germination of bean seeds?
What is a testable question?
100
Adam shows his results on a line graph and puts his dependent variable along this axis.
What is the vertical/Y-axis?
100
This is the first step in engineering, technological design or inventing.
What is a problem or need?
100
The "D" in DRY represents this.
What is the dependent variable?
100
You measure air pressure in millibars or inches of mercury with this instrument.
What is a barometer?
200
This variable would be when a scientist selects objects with different masses.
What is an independent or manipulated variable?
200
This must be in equal increments along an axis.
What is an interval?
200
When you come up with possible ways to solve a problem and work on one of them - you are doing this.
What is designing a solution?
200
The "R" in DRY represents this.
What is the responding variable?
200
Always measure the liquid curve in a graduated cylinder diagram here.
What is the meniscus or center?
300
Using the same amount of salt in a solution throughout an experiment is this type of variable.
What is a controlled variable?
300
"Higher temperatures of water take longer to freeze," based on the data is called this. BOTTLE #/TEMPERATURE OF H2O TIME TO FREEZE #1 70º F 51 minutes #2 135º F 1 hour 14 minutes #3 200º F 1 hour 29 minutes
What is a conclusion / correct hypothesis?
300
This always smaller than the actual instrument, tool or device but it helps you test the design.
What is a scientific model?
300
The "Y" represents a vertical one of these.
What is the Y-axis?
300
Fahrenheit and Celsius readings are directly across from each other on a thermometer at these degrees.
What is 0 degrees Celsius and 32 degrees Fahrenheit?
400
This measuring tool and unit could be used to measure the volume of a liquid.
What is a graduated cylinder & milliliters?
400
On a distance-time graph, a horizontal line indicates this.
What is stopped?
400
At this stage, a scientist (you) try out your design.
What is implementation?
400
"M & I" in MIX stand for these two names for a variable.
What is manipulated & independent?
400
This measures mass in grams using two pans or triple beams with riders.
What is a balance?
500
This observation usually involves numbers or measurements.
What is a quantitative observation?
500
All data has been analyzed to determine this.
What is the result?
500
After evaluating your design (determining the good and bad aspects) you do this as your final step in the technology design process.
What is communicating the design?
500
"X" in MIX is along this axis of the graph.
What is the X-axis or horizontal axis?
500
A wind vane measures wind direction and this measures wind speed and this measures relative humidity.
What is an anemometer and a psychrometer or hygrometer?
