Unit 1: Introduction to Chemistry

In this unit, students investigate a fish kill on Georgia’s Ogeechee River, and learn how to obtain, evaluate, and communicate data and information.

Start Unit

7 Segments in this Unit

Host outlines eight science and engineering practices of chemistry.

Segment A: What is Chemistry?

In this segment, we outline the eight science and engineering practices of chemistry. Students also discuss qualitative and quantitative observations.

Teacher and students discuss possible reasons for the deaths of the fish in the Ogeechee R

Segment B: Hypotheses and Models

During this segment, we introduce two Science and Engineering Practices: Generating a Hypothesis and Developing a Model.

Host creates a testable hypothesis and procedure for testing collected samples from the

Segment C: Investigating the Problem

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.

Teacher and students discuss their procedure to collect samples.

Segment D: Experimental Design

Experimental Design is explored as the terms manipulated variable, responding variable, and constant are discussed.

Teacher and students discuss the constants and variables in their investigation.

Segment E: Performing an Experiment

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.

Teacher explains the importance of data replication to minimize sources of error.

Segment F: Analyzing Data

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.

Students present their claims,evidence, and reasoning for the fish kill on a display board

Segment G: Engaging in Argumentation

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.

Segment C: Understanding Ecological Succession and Ecosystem Resilience

Now that we understand the changes that inevitably occur throughout Earth's various biomes, Cecil talks to David Zailo, Research Program Manager at the Georgia Sea Turtle Center, to better understand the stages of succession and the keystone species to look out for when determining the stage of a specific ecosystem.

VIP tour of select parts of Gulfstream.

Gulfstream Aerospace

We're given a VIP tour of some extremely impressive facilities within Gulfstream Aerospace, where we interview a wide range of employees. We begin with a focus on engineering but quickly learn there are a variety of employment opportunities available at Gulfstream. And if you’ve ever wondered how planes fly, this video will help, as our experts explain Bernoulli's Principle. Of course, once you know how they fly, you’ll want to know how fast they go. That’s why we also include explanations of the terms mach and supersonic.
