Digesters
Students will design and build a model of a mini biodigester as a hands-on project to help them apply their understanding of the purpose and function of the human digestive system.
The Iterative Nature of Science
The nature of science is more than students following a recipe of instructions in a laboratory experiment. Students are required to learn how scientists acquire knowledge through the process of scientific discovery. They learn by doing science as scientists behave in the lab.
Into the Blue Investigation
Into The Blue Investigation is a hands-on collaborative lab activity where students use their knowledge of chemistry and the scientific method to determine the reactants, products and type of a chemical reaction.
Investigating the Chemistry Inside the Breathalyzer: Oxidation of Ethanol to Acetic Acid
This exploratory/investigative experiment is designed to provide a set of laboratory skills to meet the 21st century technology standard to the students. This experiment asks the students to investigate the oxidation -reduction chemistry behind the breathalyzer.
Catalytic Oxidation of Acetone by Copper
The Bent Lab in Stanford’s Chemical Engineering Department focuses on studying the selective deposition of thin films in atomic layer deposition (ALD). These films are important for diffusion barriers, in integrated circuits. ALD is a subclass of chemical vapour deposition.
Using Electroplating to Study Properties of Metals
Students will compare the strengths of oxidizing and reducing agents, and determine resistance to different etching solutions. Students will work in small groups, developing laboratory skills while conducting a lab on electroplating.

Laboratory Notebooks in High School Chemistry as a Tool for Students to Understand and Collaborate
Students and teachers often view laboratory investigations as exercises in following directions, which grossly misrepresents the scientific process. Experimentation involves careful and methodological application of scientific principles, in which peers critique communicated results.
Use of Standards Based Grading for an Inquiry Lab on Chemistry of Airbags
In this 8th grade physical science laboratory activity about chemical reactions, students are challenged to: 1) create a reaction that would be suitable to deploy a car's airbag; and 2) construct a model of an airbag that will provide enough cushion to protect a hard-boiled egg.
