Does the Introduction of Pesticides and Fertilizers Alter an Aquatic Ecosystem?
Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.

Aquatic Ecosystem Exploration
Students visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food web for...

Oxygen Levels and Aquatic Plants and Animals
Students design an experiment to test the effects of a change in the amount of dissolved oxygen of water on aquatic plants and animals. Questions are offered for exploration and experiment design. Results are tabulated and conclusions...
Curated OER
Measuring Aquatic pH
Students apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.

Marine & Aquatic Habitats Activities - Tidal Pools
Students analyze the survival needs of different organisms and the conditions in a particular area that can affect these survival rates.
Curated OER
DOES A FLUCTUATION IN TEMPERATURE IFFECT THE GROWTH AND SURVIVAL RATE OF AQUATIC PLANTS?
Students determine if different temperatures effect the growth and survival rates of aquatic plants and evaluate the optimal temperature for the growth of aquatic plants.
Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.

Use of Dichotomous Keys to Identify Stream Organisms
What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of Stream...

Introduction to Dissolved Oxygen and Demonstration of a Simple Test Procedure
Students explain the importance of dissolved oxygen in water ecosystems. They describe the aquatic oxygen cycle and the effect of water pollution on oxygen. They make observations, collect data and draw a conclusion.
Curated OER
Water Quality and Temperature
Students evaluate the effects of temperature changes on the metabolic rate of a clam. Conclusion questions are addressed which help students to process and articulate their experiences.
Curated OER
Ecology
Students examine the relationship between the environment and those that have to live in it. They discover that we are responsible for our environment and understand the consequences of its neglect.
Curated OER
What If There's No Light?
students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment...

Is Our Water Healthy?
Students test water for a least one chemical characteristic. They hypothesize how a storm event might change the chemical characteristics of a stream. Students collect water samples and use the chemical test to test the water.
