The one parameter that is intentionally changed in a controlled experiment. This causes the responding variable to change.
What is the manipulated variable?
100
The measure of the force of gravity on an object; measured in SI in Newtons.
What is weight?
100
A guess at a measurement that helps get closer to the actual value, even though the actual value is not known exactly.
What is an estimate?
100
Graphs can give viewers an instant sense of these two qualities
What are patterns and trends?
200
Drawing conclusions from observations and knowledge.
What is inferring?
200
An educated prediction about the outcome of an experiment based on knowledge and research
What is a hypothesis?
200
The measure of the amount of matter in an object; measured in SI in grams
What is mass?
200
How close a measurement is to the actual value
What is accuracy?
200
This line gives the sense of overall trends, even for scattered data points.
What is the line of best fit?
300
Using your senses to gather information
What is observing?
300
The important final step of scientific inquiry, when the conclusions are shared with others
What is communication?
300
The measure of the amount of space something takes up; measured in SI in liters.
What is volume?
300
When multiple measurements come out the same or very close
What is reproducibility?
300
This graph works well to show how results are shared by a population. For example: to graph how much of a pizza each person ate.
What is a circle graph (or pie chart)?
400
The study of the properties of matter and how matter interacts at a molecular level
What is chemistry?
400
An explanation that tells how things came to be or why things happen or happened
What is a scientific theory?
400
This value is computed by dividing mass by volume. It tells you how heavy something will be for its size. It also tells you whether or not it will float.
What is density?
400
This results from using a graduated cylinder rather than a measuring cup (94.8 mL vs. 100 ml), or using a triple-beam balance rather than a kitchen scale (309.59 g vs. 300 g).
What is precision?
400
This type of graph works well to compare results for discreet input that cannot be ordered. For example: Which TV shows have students watched in the past week?
What is a bar graph?
500
The study of matter, energy, motion, and forces
What is physics?
500
This tells what is expected to happen in a given circumstance
What is a scientific law?
500
The temperature scale that starts counting at absolute zero, the coldest possible temperature. This scale has no negative values.
What is the Kelvin scale?
500
These are the digits in a measurement that we are sure about. The others are written as zeros or left blank if after a decimal. There are two in 1,200 and five in 1,200.0.
What are significant figures (or digits)?
500
This type of graph works best to show results for input that can be ordered. For example: How much do salmon weigh compared to their length?
