Scientific Method
The first step of the Scientific Method
The first step in the Scientific Method is: Observation
The variable that is measure/recorded/counted
The Dependent Variable is the variable that is measured/recorded/counted and it changes DEPENDING on the Independent Variable
The base unit for Length
The base unit for Length is meter (m)
1 meter = ________ centimeters
1m = 100cm
k h da (b) d c m
The vertical axis (goes up and down the page)
The y axis is the vertical axis (goes up and down page)
Number of steps there are in the Scientific Method
There are 6 Steps in the Scientific Method
The variable that is changed by the experimenter
The Independent Variable is changed by the experimenter to observe the results in the experimental trials
The base unit for Mass
250 grams = _________ kilograms
250g = 0.250kg
k h da (b) d c m
The horizontal axis (goes across the page)
The x-axis is the horizontal axis (goes across the page)
The final step of the Scientific Method
The final step in the Scientific Method is: Retest
Control Variables are factors that are kept the same/constant in an experiment to ensure the results are directly related to the experimental trials
The base unit for hectoliter (hL)
The base unit for hectoliter is liter (L)
1 dekameter = __________ meters
1dam = 10m
k h da (b) d c m
This variable goes on the y-axis
The Dependent Variable goes on the y-axis
The step in the Scientific Method that involves organizing measurements and observations into tables, charts and graphs
The Data Collection step involves organizing data into tables, charts and graphs
The purpose of a Control Group in an experiment is to be used as a comparison of the normal conditions with the experimental trials
Number of base units in a kilometer (km)
There are 1000 base units / meters (m) in a kilometer (km)
4888mL = _________ L
4888mL = 4.888L
k h da (b) d c m
The method for Titling a graph: _________ vs ________
Dependent Variable (y-axis) vs Independent Variable (x-axis)
List all of the steps of the Scientific Method

Hypothesis
Experiment
Data Collection
Conclusion
Retest
3 pumpkin plants are planted in 3 different soils (sand, clay and gravel) to test which soil type grows the heaviest pumpkins. A 4th plant is planted in the normal soil. The pumpkins are weighed after 90 days. List all the Variables and the Control Group.
Dependent Variable: Weight of pumpkins
Independent Variable: Different soil types
Control Variables: Same type of pumpkin, Same climate, Same growing period (90 days) etc.
Control Group: 4th plant in normal soil
Number of base units are in centigram (cg)
There is 1/100th of a base unit / gram (g) in a centigram (cg)
0.89165dag = __________mg
0.89165dag = 8916.5mg
