Context for Use
- This was the students first introduction to the concept of biodiversity. Many students had no or little background in this environmental studies and only basic science education in high school.
- This was taught to advanced high school students in a international studies program. The course was part of an international environmental studies elective course.
- This exercize worked well in a two hour class block.
- We walked outside of our building for the first biodiversity count. We walked down the road 10 minutes to a park with a remnant forest. It was an unmanaged forest and river area with walking paths.
- This type of activity requires an area with low biodiversity and higher biodiversity.
- We used the activity as the beginning of a discussion of biodiversity loss worldwide.
Teaching Notes and Tips
- Have students break into groups of 3 to 4 people.
- Move students outside to an urbanized area, but one with some green space, such as trees or grass. Have students count the number of species that they can find in a five minute block.
- Reassemble large group. Have student groups tell the group the number of species counted.
- Move to a naturalized area. (In this class, we moved to a "natural" city park within walking distance from campus).
- Have students repeat the count.
- In our class, we found that the students were overwhelmed by the number of species in the natural park.
- We used this as a teachable moment to discuss how the whole area used to look like the park before development; this type of biodiversity loss is happening worldwide.
