Observations and Inferences
You use your five senses to make these in science.
What is an observation?
This is the SI unit for measuring time.
What is seconds?
This is the first step of the scientific method.
What is an observation?
In an experiment, the factor that is changed on purpose is called this.
What is the independent varaible?
This type of chart is best for showing how something changes over time.
What is a line graph?
This type of observation uses your senses and describes qualities, like color or texture.
What is QUALITATIVE?
This SI prefix means one thousand (X1000).
What is Kilo?
A possible answer to a scientific question is called this.
What is a hypothesis?
This is the variable that you measure in an experiment.
What is the dependent variable?
If you want to compare the number of students in different classes, which chart would you use?
What is a bar graph?
This type of observation uses numbers and measurements.
What is QUANTITATIVE?
This SI prefix means one hundredth (1/100).
What is centi-?
This step comes after making a hypothesis in the scientific method.
What is conduct an experiment?
These are the variables you keep the same in an experiment.
What are control variables?
Graphs and charts help scientist to do this part of the scientific method?
What is analyze resuts?
When you explain or interpret the things you observe, you are making this.
What is an inference?
This SI prefix means one thousandth (1/1000).
What is milli-?
Before forming a hypothesis, a scientist should always do this.
What is research the question?
Number of times you should run an experiment to avoid human error?
What is three times?
On a graph, the y-axis usually shows this variable.
What is the dependent variable?
Scientists use observations and inferences to do this?
What is to learn about the world and solve problems?
Name the three base units for measurement and name what they measure?
meter - length
liter - volume
gram - mass
If you find that your results were different from your hypothesis, you should do this next. (2 parts)
What is revise your hypothesis or repeat the experiment?
On a graph, the x-axis usually shows this variable.
What is the independent variable?
This must be included on both axes so you know what the numbers mean.
What are labels and units?
