In this activity, students use the virtual lab to prepare a sucrose solution for a soda recipe. They next calculate the concentration of their solution in terms of molarity, percent mass and density.

The fundamental concepts of inorganic chemistry including the physical and chemical properties of matter, atomic structure, chemical bonding, stoichiometry, the gas laws, solutions, acids and bases, redox reactions, and chemical equilibria. The laboratory includes an experimental study of the chemical principles. 3 hours lecture/3 hours laboratory.
Short Description:
Ten general chemistry semester one lab exercises testing the topics of measurement, light and energy, stoichiometry, solubility, metals activity, calorimetry, and gas behavior.
Long Description:
This lab manual was designed as an inclusive lab experience covering scope and sequence for the first semester general chemistry course at the College of Western Idaho. It includes hands on activities and prompts writing and data processing associated with varied general chemistry topics following an atom’s first approach and including measurement, light and energy, stoichiometry, solubility and activity, calorimetry, and gas behavior. The manual also includes a calculation and statistical analysis appendix, sample reports, and a guide to writing reports. Each lab in the sequence is organized with pre-lab questions, a safety overview, an historical and chemical background and lab instructions as well as lab reporting instructions.

Chemistry is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning.
This video from NASA describes the detailed computer modeling used to predict that colliding neutron stars can produce gamma-ray bursts similar to those associated with black holes.
This is a laboratory exercise designed to allow students to further investigate the light spectrum. This lab is used to have students view the light spectrum first hand as opposed to using lecture alone.
Watch the ZOOM cast find out how many balloons filled with air and then with water are required to support the weight of a cast member.
In this video segment, members of the ZOOM cast experiment by bending and folding sheets of paper into various shapes to see which shape will support the weight of a heavy book.
In this video segment from ZOOM, Hillary, from Randolph, MA, takes us on a tour of the columns in her neighborhood.
This activity is a lab designed for students to combust magnesium and use results to explain oxidation/reduction reactions.
In this activity, students will create their own travel brochure or poster inviting people to visit a place where they could see an aurora. It is recommended that the class complete Lesson 1 in this series - What I know about the Aurora - prior to this activity. Includes teacher notes and instructions, student workshops and an online, animated story, and related teacher resources on aurora. This is lesson four of a collection of five activities that can be used individually or as a sequence; concludes with a KWL (Know/Want-to-know/Learned) assessment activity.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"For researchers, identifying sources of environmental contamination can be like trying to find a needle in a haystack. And that’s if they’re lucky. Because in some cases, they may not even know what to look for. In this line of work, known as non-targeted analysis, high-powered detection technology is critical to generating chemical fingerprints for unknown compounds. Just as important, however, is an expansive database that matches those fingerprints to the correct compounds. But bigger isn’t necessarily better. Researchers from the United States Environmental Protection Agency have shown that a promising new resource called the CompTox Chemistry Dashboard can actually outperform larger, well-established chemical databases, pointing to streamlined approaches to ID-ing potentially harmful contaminants. The CompTox dashboard uses a ranking approach similar to that of the popular database ChemSpider..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.
This activity is an instructional activity that can be used in AP Chemistry with Topic 1.1. The activity has students arrange samples with different units in three different ways to show that they know how to perform different mole problem calculations.
Students will be conducting a series of investigations in order to compare and contrast the various intermolecular forces that exist between compounds. First, students will rank 4 substances according to their melting points. Second, students will work together using the jigsaw research approach to understand the 4 types of intermolecular forces. And lastly, students will use the information gained to go back to their data collected and compare their original compounds and type of intermolecular bond they exhibit. This lesson plan results from a collaboration between the Alabama State Department of Education and ASTA.
Students compare the chemistry and structures of biotite, muscovite, and chlorite.
