This lab enables you to construct a physical scale model of a stream system to help you understand how streams and rivers shape the landscape, and how human actions can affect river ecosystems. This lab is done with materials that you will need to supply; the list of items you will need to obtain is in the Stream Morphology Investigation Manual. The process involves taking required photos, completing all parts of the assignment including calculations and data tables, and answering all questions in the “Lab Questions” section. You will transfer all answers and visual elements from the “Lab Worksheet” into the “Lab Report.” Both the “Lab Report” and the “Lab Worksheet” need to be submitted through Waypoint.

Paper For Above instruction

The purpose of this laboratory exercise is to provide a hands-on experience in understanding stream morphology and its impact on landscape formation, as well as analyzing human influences on river ecosystems. Constructing a physical scale model of a stream system allows students to observe the natural processes of erosion, transportation, and sediment deposition that shape river channels and floodplains. Additionally, this activity emphasizes the importance of scientific methodology and data collection in environmental science.

Before initiating the experiment, students are instructed to thoroughly review the Stream Morphology Investigation Manual and the “Scientific Method” presentation video. These preparatory steps ensure that students understand the theoretical concepts and procedural guidelines essential to conducting the experiment effectively. The manual provides detailed instructions on assembling the model, selecting appropriate materials, and photographing the activities accurately.

The experiment is divided into two primary activities. Activity 1 involves constructing the initial stream model. Students will shape the streambed, place sediment, and initiate water flow to observe natural processes such as erosion and sediment transport. Activity 2 introduces variables such as human interference—such as construction or pollution—to examine its effect on the stream’s morphology and flow characteristics. Throughout the experiment, students are required to photograph their work, ensuring each image includes a strip of paper with their name and date for identification and validation purposes.

Data collection is central to this exercise. Students are required to complete the Week 1 Lab Worksheet, which includes recording measurements, observations, and answering questions related to stream flow, sediment movement, and environmental impacts. These responses should be directly transferred to the Lab Report template, which consolidates all data, visual evidence, and analysis for submission. The assignment stresses the importance of meticulous data recording, proper organization, and clear articulation of observed phenomena.

Upon completion, students will submit both the Lab Worksheet and the Lab Report through the designated online platform, Waypoint. The final report should reflect a comprehensive understanding of stream dynamics, demonstrate the ability to analyze environmental change, and communicate findings effectively. This hands-on activity aims to deepen scientific understanding, develop critical thinking skills, and foster an appreciation for the complexity of natural systems and human influence.
