Graphing environmental statistics

Overview

Students will develop their graph and data analysis skills by converting data tables from Human Activity and the Environment into graphs.

Students will graph and analyze data on a specific topic (e.g. greenhouse gas emissions, transportation, water resources, etc.). This activity can be used to complement your present unit/course, or it can be used solely as a graphing and data analysis exercise.

Objectives

• To learn about Canada’s ecosystems and responses to human activity on the environment
• To convert data from table to graph form
• To use graphs effectively
• To analyze data from graphs to make conclusions
• To communicate findings to others in an effective manner

Suggested grade level and subject areas

Intermediate
Geography, Environment, Math

Duration

One to two 60-70 minute periods depending on how many graphs students are expected to produce.

Vocabulary

Vocabulary will vary based on selected sections.

Materials

• Human Activity and the Environment, selected issue of your choice
• Computer
• Graph paper, ruler, paper, markers, coloured pencils
• Student worksheet
• Evaluation tool

Classroom instruction

This activity would be best utilized in a unit where graphing has been covered. In geography this lesson may be introduced as part of natural resources and the environment or patterns in human geography. In science this lesson may be introduced as part of earth and space systems. In Math, this lesson may be introduced as part of statistical analysis and graphing.

1. If a section of the publication is applicable to the unit/course, use the section to supplement what has already been taught.
2. Instruct students on:
   • how to read tables
   • the proper way to produce graphs
   • how to analyze graphs
3. Distribute copies of selected tables or access the "Tables" section in your chosen issue of Human Activity and the Environment.
4. Assign activity. Students may be assigned tables or be permitted to choose the tables they will graph and analyze.
5. Evaluate students’ graphs and analysis using the evaluation tool.

Note: Different types of graphs can be used depending on students’ experience with graphing. For example, it is suggested that students with minimal graphing experience create either a circle graph/pie chart or bar chart using only one or two sets of data. For students with extensive graphing experience it is suggested that they use multi-line graphs using three to five sets of data. See graph examples.

Evaluation

The graphs can be evaluated by using the evaluation tool.

Enrichment

• Students could create a survey to be distributed among the class based on their topic and graph their findings.
• Students could use E-STAT to obtain additional data based on their topic.
• Students could research their topic further and incorporate their graphs and findings into a short report or presentation.
