Curated OER
Water Quality
Learners play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.
Curated OER
Ecosytems: Water Purification
Students explore how ecosystems purify water and what kinds of things humans do that alter these processes. They use a website to access information on local watersheds and develop a "river" newspaper
Curated OER
Yeast Cells and Their Environment
Students create their own experiment in which they have yeast cells growing in liquid environments. They examine the relationship between humans and microorganisms. They also practice using the scientific method.
Curated OER
In the Scheme of Things
Fifth graders examine the food webs of different animals. They discuss the characteristics of those animals as well. They work together to develop their own definition for the word niche.
Curated OER
Date a Rock!
Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
