Scientific Methods
You make these by using your senses.
What are observations?
Students drop different objects from the same height and measure the time it takes for each object to reach the ground. The _______ would be the independent variable.
What are the different objects.
Put the following in order from largest to smallest:
cm, hm, dm, km, m, mm
What is km, hm, m, dm, cm, mm
300 Kelvin is this temperature in Celsius.
What is 27*C?
This type of graph is most useful to show how the relationship between the independent and dependent variables changes over time.
What is a line graph?
This occurs when the scientist's expectations changes how the results are analyzed or the conclusions are made.
What is bias?
Students drop different objects from the same height and measure the time it takes for each object to reach the ground. The _______ would be the dependent variable.
What is time it takes the objects to reach the ground?
This prefix represents 1/1,000.

615 milligrams is equal to this amount in grams.
What is 0.615 g?
The independent variable will be plotted on this axis.
What is the x-axis?
A testable prediction or explanation for a problem using what you know and what you observe.
What is a hypothesis?
Students drop different objects from the same height and measure the time it takes for each object to reach the ground. The _______ would be a constant variable.
