Graphs
Types of graph
Bar Chart
The type of information used in a bar chart is categorical data.
Line Graph
The type of data represented in line graphs is discrete data
In a line graph the independent variable goes vertically and the dependent variable goes horizontally
Pie Chart
The type of data in pie charts is statistical.
Patterns in graphs
Writing Conclusions for Graphs
Variables
Control Variable:
The control variable is the thing that you keep the same in your experiment
Independent Variable:
The independent variable is the thing that you change in your experiment
Dependent Variable
The dependent variable is the thing that you measure in your experiment
How to Ask a Scientific Question
https://oepos.ca.uky.edu/files/asking_good_scientific_questions.pdf
This is a good website that will answer any questions you have about scientific questions.
To use observations to ask scientific questions you must simplify your question to be able to answer this question in an experiment.
What is a scientific question?
A scientific question is
not
a matter of
opinion
, it needs to be able to be
measured
and proven.
Scientific question: Which car has the longest maximal time of driving without any fixes/changes needed to be made to it?
In this case we can measure this by setting out an experiment, it is not a matter of opinion and it is specific on what calculation we need to make
Not scientific
: Is a Racing car
better
than a normal car?
What is better supposed to mean? Is it speed, comfort, size........
How to Plan an Investigation
To plan an investigation you must first ask a scientific question that can be investigated, next make a prediction about what will happen; decide on what your variables are going to be. Fourth, choose the equipment, decide on a method and do a risk assessment. Next, decide on how you will record your data and after that do your experiment and record your data; present your data on a graph. Lastly, identify patterns in your results and explain them.
