Curated OER
Stream Ecology In Wisconsin and Puerto Rico
Students identify the different types of water and explain in what proportions they exist on Earth. They identify and correctly label the parts of the water cycle and how these parts interact with each other. Students identify the...

WET Science Lesson #11: How Light Affects Water
Scientists listen to the story of Wadja Egnankou who works to save African mangrove forests. They experiment with refraction and the introduction of particulate matter to water. They conclude with creative writing about the need for a...
Curated OER
Dissolved Oxygen and Respiration
Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...
Curated OER
Dissolved Oxygen and Temperature
Students are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
High schoolers are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use...
Curated OER
Aquatic Ecosystem Exploration
Learners 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...
Curated OER
Life in a Forest Stream
Students assess macro-invertebrates from a stream. In this science lesson plan, students observe, classify and identify organisms found in a stream. A lab station is constructed at the stream sight and students study the different...
Curated OER
Selecting Soil Organisms in Compost
Learners conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Selecting Soil Organisms in Compost
Pupils demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment in...
Curated OER
Butterfly Lesson
Students identify that Idaho is a home to 168 species of butterflies and they are an important part of many habitats. They also identify how to use the Digital Atlas of Idaho and write a report regarding information of their assigned...
