Graphs & Variables
What does a graph show?
The pattern or trend of data along an x and y axis
What was the purpose of our experiment Material Matters?
To observe that different materials gain or lose heat at different rates
What does F stand for when measuring temperature?
Fahrenheit
What is the definition of kinetic energy?
What is the energy of motion?
What Great Lake is Detroit connected to?
Lake Erie
Which variable typically goes on the x axis?
Independent Variable
What was the takeaway from our Amount Matters experiment?
That a the more of a liquid is present, the longer it will take to heat up
What does C stand for when measuring temperature?
Celsius
Average kinetic energy
How many Great Lakes are there in the US?
Five
For the ordered pair (3,2), how far over on the x axis is it and how far over on the y?
x = 3 and y = 2
If I put two cups with an equal amount of oil and water outside today, which will freeze first?
The water
What is the freezing point of water? (In degrees C)
0
What is thermal energy?
Kinetic and potential energy in something
Which US State is home to the Great Salt Lake, the largest salt lake in North America?
Utah
Why are control variables important?
They help you isolate the variable you are testing to ensure what the connection is
If I put 1 and 3/4 cups of water on the stove to boil, and next to it put 1 and 2/3 cups of water to boil, which will boil first?
1 and 2/3 cup
How do you calculate change in temperature?
Final minus initial
What does thermal energy transfer mean?
Heat being passed from one object to another
Which North American country has over 2 million lakes?
Canada
What is the dependent variable?
The response variable, the variable that responds to the changes you make with the independent variable.
Will a cup of water freeze faster outside today or in a fridge?
Outside (A fridge isn't cold enough to freeze a cup of water)
How do you calculate average change in temperature?
Final minus initial divided by time
What are the two ways you can measure kinetic energy?
What is thermometer (temperature) or how far something has moved?
Why are shallower parts of a lake much warmer than deeper parts?
Because amounts matter, the shallower parts are heated quicker by the sunlight! (Various answers accepted here)
