Lab Report
The photographs in the Lab Report are the same photos you viewed in the on-screen slide show. They were
taken after Mount Saint Helens erupted in Washington State in 1980. For the Lab Report, you will compare and
contrast the photos, and make observations of the biotic and abiotic factors present in each. If you wish, you may
go back to the on-screen slide show to view the photos while you keep the Lab Report open and answer the
questions.
1. This photograph was taken at a location on Mount Saint Helens called Meta Lake. The area was clear-cut
before the volcano erupted in 1980, meaning that all trees were cut down and used for timber or other
products. The photograph was taken in 1983, 3 years after the volcano erupted. Describe the biotic and
abiotic factors you see in the photograph.
Answer:
2. This photograph was taken in 1989, 9 years after Mount Saint Helens erupted. Compare this photo with the
1983 photo. What has changed? What looks different? How do you think those changes might have come
about?
Answer:
3. This photograph was taken in 1994, 14 years after Mount Saint Helens erupted. Compare and contrast this
photo with the previous two. What changes do you see in the biotic and abiotic factors?
Answer:
4. This photograph was taken in 2004, 24 years after Mount Saint Helens erupted. Compare and contrast this
photo with the previous three. What changes do you see in the biotic and abiotic factors? Does anything
surprise you about this series of photographs?
Answer:

Introduction:
The eruption of Mount Saint Helens in 1980 has remained one of the significant natural disasters that have shaped the environment in Washington State. Since then, several scientists have conducted studies on the impact of the event on the ecology of the region. One such study is the Lab Report that compares and contrasts photographs taken after the eruption to identify the biotic and abiotic factors present in the area.

Description:
The Lab Report contains a series of photographs taken after the eruption of Mount Saint Helens and aims to identify changes in the environment over time. The report focuses on four photographs taken in 1983, 1989, 1994, and 2004, respectively. The report seeks to answer questions related to biotic and abiotic factors present in the area. In addition, students are required to make observations and comparisons between the photographs to identify changes and factors that may have contributed to those changes. The Lab Report provides valuable insights into the impact of volcanic eruptions on the environment and the subsequent recovery of ecologies over time.

Headings:
1. Introduction
2. Description

Objectives:

– To compare and contrast the photographs of Mount Saint Helens before and after the eruption.
– To observe and identify the biotic and abiotic factors present in each photograph.

Learning Outcomes:

By the end of this lab report, you should be able to:

– Analyze and describe the changes in biotic and abiotic factors in the photographs taken at different times after the eruption of Mount Saint Helens.
– Explain how natural disasters can have a significant impact on the environment and its ecosystems.
– Develop critical thinking skills in making observations and drawing inferences from photographic evidence.

Heading 1: Analysis of Photograph from Meta Lake

Objective: To identify and describe the biotic and abiotic factors present in the photograph of Meta Lake.

Learning Outcomes:

– Identify biotic factors, such as plant life, visible in the photo.
– Identify abiotic factors, such as the presence of water and soil.
– Understand how clear-cutting of trees impacts an ecosystem.

Heading 2: Comparison of Photographs from 1983 and 1989

Objective: To identify and describe the changes that occurred between the photographs taken in 1983 and 1989.

Learning Outcomes:

– Compare and contrast the two photographs to identify any changes in the biotic and abiotic factors.
– Analyze the potential reasons for the changes observed, such as changing weather patterns or human interference.
– Develop an understanding of how ecosystems can evolve and change after a natural disaster.

Heading 3: Comparison of Photographs from 1989 and 1994

Objective: To identify and describe the changes that occurred between the photographs taken in 1989 and 1994.

Learning Outcomes:

– Compare and contrast the two photographs to identify any changes in the biotic and abiotic factors.
– Analyze the potential reasons for the changes observed, such as the growth of new plant species or the shifting of soil.
– Understand how ecosystems can recover and adapt after a natural disaster.

Heading 4: Comparison of Photographs from 1994 and 2004

Objective: To identify and describe the changes that occurred between the photographs taken in 1994 and 2004.

Learning Outcomes:

– Compare and contrast the two photographs to identify any changes in the biotic and abiotic factors.
– Analyze the potential reasons for the changes observed, such as increasingly favorable weather conditions or natural succession.
– Understand and appreciate the resilience of ecosystems and their ability to recover and flourish after a natural disaster.

Solution 1:

Based on the observations made in the Lab Report, one possible solution is to conduct a study on the process of ecological succession at Mount Saint Helens. The study can focus on the changes that have occurred in the biotic and abiotic factors over time, and explore the impact of these changes on the ecosystem. By understanding the successional patterns that occur in this ecosystem, we can gain valuable insights into the natural processes that govern the growth and development of ecosystems.

Solution 2:

Another possible solution is to consider the potential for reforestation efforts in areas that were clear-cut prior to the eruption of Mount Saint Helens. By planting trees and other vegetation in these areas, we can help to restore the biodiversity and ecological integrity of the ecosystem. This could involve the use of native species that are well-suited to the area, and the implementation of restoration techniques that support the establishment and growth of new vegetation. Such efforts would not only contribute to the ecological health of the area, but could also provide important economic benefits through the production of timber and other products.
