Activity 03: Analysis data

Handling and analyzing biodiversity data with graphs

Objective: Learners will learn how to deal with information on the basis of different forms of representation and assess their advantages. Additionally, they will learn how to analyze data.
Learning outcomes: Learners are able to use basic strategies for extracting information from graphs and statistics. They are able to receive geographically relevant information and its relation from graphs. Additionally, they are able to transfer the information received into different forms of representation.
Previous knowledge: Knowledge of data analysis and its forms of representation.
Duration: 45 min
Materials / Conditions: 2 figures (cf. ressource 1)
Methods / Techniques: Descripton and Analysis, prioritizing, transfer
Learning subject: Biodiversity / Module 3: collection, processing and analysis of environmental data / Level: Advanced Learning


Introduction:
In order to explain biodiversity, it is necessary to able to analyze and relate data extracted from graphs. Trends show that the diversity of species is decreasing continuously, which is worth analyzing.

Instruction:
Take a look at the two graphs (Resource 1 and 2).
1. Describe Figure 1.

2. Analyze Figure 1 with the help of Figure 2.

3. Think of the advantages of data analysis with the help of graphs, especially when compared to data in a written text format.

Resources:

Possible results / Results:
1.Starting in 1985, the entire biodiversity decreases by around 35 percent. This affects fresh water species most severely. Terrestrial species are the least affected. The decline of marine species lies somewhere between the decrease of the other species but has started to recover in 1999.

2. Possible reasons may be an increase in air pollution and the overexploitation of freshwater resources. The change in habitat conditions due to climate change is another possible reason. Mostly affected are the freshwater areas. Increased deforestation of rain forests leads to the reduction of biodiversity.

3. Graphs can be interpreted easily and quickly as they are very clear. Correlations and differences are presented through color and accentuation. A course of events can be recognized easily and does not have to be reconstructed. There’s a concentration of information which does not have to be extracted from a long text also containing irrelevant data.
