Pillars of Science
Name the 3 main pillars of science.
Life, Physical, and Earth and Space Science
If an object is dropped in a vacuum, then it will accelerate at the exact same rate regardless of its mass, because there is no air resistance to slow it down
Hypothesis
In an experiment testing how fertilizer affects plant growth, what is a reasonable independent variable?
Fertilizer
Convert 1000 millimeters to meters.
1 m
Which graph type is best to compare categories (e.g., counts of different species)
Bar Graph
The branch of science dealing with matter and energy is:
Physical Science
The inheritance pattern of one specific trait will not influence or depend on the inheritance pattern of another unrelated trait during the formation of reproductive cells. P(A and B) = P(A) x P(B)
LAW
In an experiment testing how fertilizer affects plant growth, what is the dependent variable?
Plant Growth
Convert 5 kilometers to meters.
5,000 meters
What graph type is best to show how one variable changes over time?
Line Graph
Which branch of science is the study of the diversity of life?
Biology
When dropped from a height at sea level, an apple falls toward the center of the Earth.
FACT
List three examples of constants (controlled variables) you should keep the same across all plants in that experiment.
Same Soil
Same Plant
Same Light
Same Water
Same Time
2,500 mg to grams
2.5g
You have paired numerical data (height vs. shoe size) for many students; which graph type helps show correlation between variables?
Scatterplot
What is one of the main branches of Earth and Space Science?
Geology, Astronomy or Meteorology.
Genes are specific segments of DNA physically located at fixed positions on chromosomes, which duplicate, align, and separate during cellular division to pass genetic information to new cells.
Theory
Explain the difference between the control group and the experimental group in an experiment.
Control group: group not receiving the experimental treatment (e.g., plants with no fertilizer). Experimental group: plants receiving the fertilizer treatment(s).
What unit do we use to measure mass in the metric system?
Grams
On which axis is the independent variable always located?
The x-axis
What is the study of matter, its properties and how substances combine and change?
Chemistry
What is the difference between and scientific theory and a scientific law?
A scientific theory explains "WHY" or HOW" something happens. Backed by evidence.
A Scientific law describes "WHAT" happens. Backed by Math.
A student investigated whether ants dig more tunnels in the light or in the dark. She thought that ants used the filtered light that penetrated the upper layers of earth and would dig more tunnels during the daytime. Ten ant colonies were set up in commercial ant farms with the same number and type of ants per ant farm. The same amount of food was given to each colony, and the colonies were in the same temperature. Five of the colonies were exposed to normal room light and five were covered with black construction paper so they did not receive light. Every other day for 19 days the length of the tunnels was measured in millimeters using a string and a ruler. What is the IV, DV, Constant, Control Group and Experimental Group?
IV - The amount of light the ants recieved
DV - The length of the tunnels in mm
Constants - temp, food, number of ants per farm,
What unit do we use to measure volume in the metric system?
Liters
Changing the results of an experiment or analyzing results a specific way in order to fit personal beliefs is called:
bias
prejudice
discrimination
conclusion
A. Bias
