In this unit, students investigate a fish kill on Georgia’s Ogeechee River, and learn how to obtain, evaluate, and communicate data and information.
In this segment, we outline the eight science and engineering practices of chemistry. Students also discuss qualitative and quantitative observations.
During this segment, we introduce two Science and Engineering Practices: Generating a Hypothesis and Developing a Model.
We explore the steps involved in creating and testing a hypothesis and introduce our third Science and Engineering Practice, planning and carrying out an investigation.
Experimental Design is explored as the terms manipulated variable, responding variable, and constant are discussed.
In this segment, students learn about the importance of lab safety procedures while performing an experiment testing the pH of various samples in the classroom.
Students analyze data collected in the last segment and interpret that data by constructing an argument that explains whether the data shows that their hypothesis should be supported or rejected. Significant figures are mentioned and the importance of data replication is also discussed.
In this segment, students engage in argumentation by either rejecting or supporting their hypotheses about the fish kill. We hear from environmental lawyer Don Stack, who discusses the role of chemistry in his profession.
We pay a visit to the CSX REDI Center in midtown Atlanta, where we talk with the fine folks of CSX about their 3,000 employees scattered around the state. REDI is the acronym for Railroad Education and Development Institute. That’s where most CSX employees come to learn about what it takes to work on the railroad, which also makes it a great place for us to learn more about CSX jobs.
The University of Georgia's College of Agricultural and Environmental Sciences invites us on a tour of its Mountain Research and Education Center, where we interview Dr. Wayne Hanna, one of the foremost turf growers in the world! He’s grown grass for sports complexes as far away as the World Cup Soccer Tournament in South Africa, and as close to home as UGA’s own athletic fields. Teachable Moments center around agriculture, including photosynthesis, the nitrogen cycle, and more.
Students explore the chemical and physical properties of matter and discover how scientific ideas are connected to each other rather than existing in isolation.
