4.5 Graphs and tables

This lesson

• Completing paragraph 4.4
  
• Graphs and tables
  
• Project speed
  

Learning goals

• Be able to read speed-time graphs.

• Calculate distance traveled using a speed-time graph.

•  Explain terminal velocity in your own words.

• Explain what is meant by a continuous variable and a discrete variable.

•  know when to use a pie chart, bar chart or graph.

What does the area under a graph tell you?

• Area = length x width
  

• Area under speed time graph =  speed x time
  

•  speed x time = distance traveled
  

Terminal velocity

4.5 Graphs and tables

tables and graphs – Exercise

1. Read 4.5

2. Give a definition in your own words for the following concepts:

• Discrete variable – give an example.
  
• Continuous variable – give an example. 
  
•  Categoric variable – give an example
  

•  Bar chart – draw an example of a bar chart.
  
• Pie Chart – draw an example of a pie chart.
  
• Line graph — draw an example of a line graph.

Discrete variable

• A variable which you can only express in whole numbers. 
  
• Example: The number of goals in a soccer match.
  

Continuos variable

• A variable that can take any number.
  
• Example: the temperature in a room.
  

Categoric variable.

• A variable that is not expressed in numbers
  
• Example: the names of players in a sports match.
  

Bar chart

Pie Chart

Line graph

Exercise

1. In your notebook write down:

• Discrete variable
  
• Categoric variable
  
• Continuous variable
  

2. Behind each variable, write down which type of graph you use for it.

•  Graph
• Bar chart
• Pie chart

project speed

project speed

• You wil do your own investigation into speed, In groups of four.

• You will have to formulate your own research question.

•  For the a final product you will have to create an A3 poster outlining your research
