Biome Climatogram Lab
Pre-lab:
1. Prepare spaces for 7 separate graphs by setting up and labeling axes as specified below (see p. 149)
 Label the Y-axis on the left side of the graph: cm
 Label the Y-axis on the right side of the graph C
 Use a line graph to indicate (graph) the temperatures.
i. Mark off each C box numbering by twos. Start with -36 at the bottom and end with 36
at the top.
 Use a bar graph to graph the precipitation.
i. Mark off each cm box numbering by twos. Start with 0 at the bottom and end with 36 at
the top.
Procedures:
1. Follow the instructions above to graph the climate of each biome. This is called a climatogram. Pay
attention to negative and positive values. Be sure to label each with the correct biome.
2. Graph the climate of each unknown biome.
3. Compare the graphs of the unknown biomes to the known biomes. Analyze and try to identify each
unknown biome. The unknown biomes are different biomes than the ones you were given.

Post- Lab Analysis:
1. Identify the 3 “mystery biomes”. Explain your reasoning.
2. What is a climatogram, why is it useful?
3. What are the 2 major factors that determine climate, and explain how these factors affect ecosystems.
4. List one location on Earth where you could find each biome that you graphed (7 total).
5. What is the average yearly temperature for the Desert biome? Average yearly precipitation?
6. List and explain 2 reasons why 2 locations at similar latitudes could be different biomes.
