World Population Activity II: Excel

Activity and Starting Point page by R.M. MacKay. Clark College, Physics and Meteorology.

This material was originally created for Starting Point:Introductory Geology
and is replicated here as part of the SERC Pedagogic Service.

This activity has been reviewed by 2 review processes (view details)

This resource received an Accept or Accept with minor revisions rating from a Panel Peer Review process

These materials were reviewed using face-to-face NSF-style review panel of geoscience and geoscience education experts to review groups of resources addressing a single theme. Panelists wrote reviews that addressed the criteria:
1. scientific accuracy and currency
2. usability and
3. pedagogical effectiveness
Reviewers rated the resources:
1. Accept
2. Accept with minor revisions
3. Accept with major revisions, or
4. Reject.
They also singled out those resources they considered particularly exemplary, which are given a gold star rating.

Following the panel meetings, the conveners wrote summaries of the panel discussion for each resource; these were transmitted to the creator, along with anonymous versions of the reviews. Relatively few resources were accepted as is. In most cases, the majority of the resources were either designated as 1) Reject or 2) Accept with major revisions. Resources were most often rejected for their lack of completeness to be used in a classroom or they contained scientific inaccuracies.

Summary

In this activity students import UNEP World population data/projections from either the World Population Prospects: The 2002 Revision Population Database UN Population Division or a text file. Students first graph this data by itself, and then along with logistic growth model predictions, and assess the model's ability to simulate the observed past and UNEP future projection of world population. Less detailed instruction is given here than in World Population Activity I as students are now assumed to be somewhat familiar with Excel.

Import data from text files
Graph data and perform simple rate calculations
Assess model behavior by comparing model predictions to observations
Learn about World population and limited growth

Context for Use

This activity and activity I provide a good overview of how to use Excel. These are appropriate for courses that intend to have students use Excel as a lab tool, for homework, or for modeling activities.

Description and Teaching Materials

Activity Sheet (Excel 2003 version) (Acrobat (PDF) 694kB Aug10 03); Activity Sheet (Excel 2007 version) (Acrobat (PDF) 525kB Dec9 10)
Answers Document (Excel 62kB Apr3 04) with several sheets representing different levels of completion. These Excel documents can be used for either:

Introducing concepts and ideas in an interactive lecture
Making transparencies or power point slides
Checking student results

A text file of UNEP data/projections UNEP Population ( 788bytes Apr3 04)
Sample images of what's in the Excel Answer Document and what students are expected to accomplish.

Figure 2. Med-UNEP medium projections for World population to 2050 and Logistic model "best" fit. (Ao=2.52, K=10.8, and r=2.8)

Teaching Notes and Tips

This activity will take students about 2 hrs to complete. Students unfamiliar with Excel should complete Activity I before working through this activity as less detailed instructions are provided in this second activity. Students should be able to work through this activity at home or in a computer lab will no supervision. Students more familiar with Excel can work through this activity more quickly.
