The idea for this activity came from several other lesson plans designed for transect survey sites. I was inspired by the following lessons:
“On-Site Lesson Plan” in Monitoring Creek Health
“Activity 7: Microhabitats” in the book Environmental Science Activities Kit : Ready-To-Use Lessons, Labs, and Worksheets for Grades 7-12 by Michael Roa
“Weeding Out – River Plant Survey”, “A Matter of Trash – Pollution Survey” and “Macroinvertebrate Investigation” from Friends of the LA River’s science curriculum
See the Soil Analysis Lesson for source information about the soil analysis tests.
You can obtain 15 ml graduated test tubes from BD sciences.
Ecology (Life Sciences)
5. Organisms in ecosystems exchange energy and nutrients among themselves and with the environment. As a basis for understanding this concept:
a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs.
b. Students know matter is transferred over time from one organism to others in the food web and between organisms and the physical environment.
c. Students know populations of organisms can be categorized by the functions they serve in an ecosystem.
e. Students know the number and types of organisms an ecosystem can support depends on the resources available and on abiotic factors, such as quantities of
light and water, a range of temperatures, and soil composition.
5. Chemical reactions are processes in which atoms are rearranged into different combinations of molecules. As a basis for understanding this concept:
e. Students know how to determine whether a solution is acidic, basic, or neutral.
Investigation and Experimentation
7. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform
