Scientific Method
DAILY DOUBLE: Contrast qualitative and quantitative data
Qualitative Data - Quality of something
Quantitative Data - Quantity of something
Describe what occurred when scientists gained access to the polar regions.
What is collect data on gasses using ice drilling through the various layers of ice sheets?
What are quadrats?
What is a square frame used to isolate an area to collect the number of plants or specific species are living there.
0 - no biodiversity
1 - high biodiversity
Something within the ground that holds water.
What is an aquifer?
This is something that the researches changes.
What is the independent variable
What is sampling?
What is where you take a set of data from a larger population for measurement.
These are used to collect insects from land.
What is a sweep net?
Lincoln Index = n1 x n2 / m2
Researchers went to the local pond to calculate the population of ducklings living there. In their first capture, they collected and tagged 10 ducks. 2 weeks later, they collected 15 more ducks, 5 of which were tagged. What is the estimate population of ducks in the pond?
What is 30?
DAILY DOUBLE: What is air pressure?
What is the force of air pressing down on Earth (or weight of air)?
This remains constant throughout you experiment.
What is the control?
Contrast primary and secondary data.
Primary - information that is collected by the researcher.
Secondary - Collected by a separate investigation.
These are used to help measure turbidity.
What is a secchi disk?
Lincoln Index = n1 x n2 / m2
Researchers went out to the local forest to collect samples on squirrels. In their first catch, they had 17 squirrels. 5 weeks later, they collected 14 untagged and 7 tagged. What is the estimated population of squirrels in the area?
What is 51?
Describe carrying capacity.
What is the maximum amount of population something can hold before it becomes damaged?
This is something that changes based on the independent variable.
What is the dependent variable?
Describe random sampling.
What is where samples are based on a random drawing.
These are used to collect nocturnal insects.
What is a light trap?
a - 1
b - 3
c - 2
d - 6
What is 65%?
RANDOM: What layer of the atmosphere do meteroids burn up in?
What is the mesosphere?
Describe systematic sampling.
What is where samples are based on regular intervals.
These are used to hit insects off of trees or bushes.
What is a beating tray?
RANDOM: This can indicate pollution, habitat destruction, climate change
What is declining biodiversity?
Describe transpiration.
What evaporation from trees?
