Science - Earth Science
Students will understand the dynamics of the hydrosphere.
Analyze the characteristics and importance of freshwater found on Earth's surface and its effect on living systems.
Abiotic and Biotic Factors
This lesson helps students understand abiotic and biotic factors. Once the concept has been grasped, they can trace the interactions of these factors within a system.
Biodiversity Debate - Stream Side Science
In this exercise, students will hold a debate about the construction
of a dam in terms of the biological, aesthetic, ethical, social or
economic arguments with regard to maintaining biodiversity.
Students will be assigned different roles to argue either for or
against the dam.
How Much Water Do You Use? Webquest
By accessing the website Conserve Water, students will learn about water usage and the importance of conservation.
Students should gain a greater understanding of how and why chemical dumping occurs. They will also better understand how pollution spreads through underground reservoirs.
Missing Macroinvertebrates - Stream Side Science
In this exercise, students will collect macroinvertebrates from a
stream site, sort and identify them, and use their findings to
identify current and past impacts to the quality of the water. They
will also make predictions of how the impacts to the water quality
contributed to the localized extinction of some types of
Nitrogen Cycle - Stream Side Science
Students will learn about the nitrogen cycle through discussion and
the construction of a diagram. They will also measure the nitrate
levels in various water samples and discuss how humans affect
nitrate content in the water.
Picturing Water Quality
Students will research a water quality indicator and prepare a summary to present to the class. They will create a picture to help explain their indicator.
Riparian Review - Stream Side Science
In this exercise, students will identify and observe biotic factors in a
riparian ecosystem, which is the green strip of vegetation alongside
a waterbody; they will measure the types of vegetation at the water's
edge, the function of plants as ground cover and canopy cover, and
observe the wildlife in the area.
That's Predictable - Stream Side Science
In this exercise, students will be asked to research and report on
ecosystem changes that occur as a result of changes in an aquatic
Students will be given a sample of dirty water. Their job will be to develop a process to purify the water.
Water Conservation Checklist
Students will create pictograms of ways to conserve water.
Water Management - Stream Side Science
In this exercise, students will be assigned roles as community
members, develop questions and positions, and participate in a
mock "community meeting" to discuss the development of a water
use plan that addresses water shortages, distribution, and water
Students will use water quality tests to determine the quality of water collected from local water systems.
Wetland vs. Stream Macroinvertebrates - Stream Side Sci
In this exercise, students will use their data from the activity Who Lives in the Water? or Missing Macroinvertebrates and compare it to a macroinvertebrate sample collected from a wetland site.
What's in the Water? - Stream Side Science
In this exercise, students will observe and list abiotic factors in an
aquatic system and measure four of them (pH, dissolved oxygen,
turbidity and temperature).
When Things Heat Up - Stream Side Science
In this exercise, students will measure the temperature and dissolved oxygen of a stream (or use their findings from the activity What's in the Water?) and discuss what this information can tell us about possible pollution problems.
Who Lives in the Water? - Stream Side Science
In this exercise, students will collect and observe
macroinvertebrates in an aquatic system. They will record and
summarize their findings.
pH Changes in a Small Ecosystem
A pond water/hay infusion will be developed and observed. Student groups will add a range of acid and base solutions to look for changes.
