- Abstract: You can access the problems below via the Load Homework dialogue in the File menu of the Virtual Lab. They have been organized by concept and ranked by difficulty (A ranking of 1 denotes an easier problem; 5 is more challenging). Word files for these problems are provided so that you may edit and distribute the assignments in your classroom. The following types of problems can be found:Strong and Weak Acid and Base Problems, Determination of the pH Scale by the Method of Successive Dilutions, Standardization of NaOH: Acid Base Titration, Determining the pKa and concentration ratio of a protein in solution, Unknown Acid and Base problem, Creating a Buffer Solution, DNA - Dye Binding: Equilibrium and Buffer Solutions.

- Abstract: In this video segment adapted from ZOOM, two cast members demonstrate what happens when vinegar is added to baking soda inside a container. The resulting chemical reaction produces enough carbon dioxide to launch their paper rocket skyward.
Recommended for: Grades K-5

- Abstract: A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.

- Abstract: It would seem that bottles of lemon juice and rockets have only their basic shape in common. However, as two cast members from ZOOM demonstrate in this adapted video segment, when baking soda is added to the mix, a plastic bottle can act very much like a real rocket. Grades 3-8.

- Abstract: In this activity, students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.

- Abstract: To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.

- Abstract: Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. In a hands-on activity, students build a conductivity tester to determine whether different objects are conductors or insulators. In another activity, students use their understanding of electrical properties to choose appropriate materials to design and build their own basic circuit switch.

- Abstract: This is an on-line prototype for a book aimed at teaching kids the effects of acid mine drainage on our environment through experimentation and observation. Experiments introduce litmus paper, pH testing, neutralization, identification of aquatic organisms and their use as water quality indicators, acid mine drainage, organisms in acidic environments (including plants, bacteria, and algae), oxidation-reduction reactions, the manganese cycle, the water cycle, and treatments for acid mine drainage. The entire document is also available in a downloadable Adobe PDF format.

- Abstract: Laboratory Chemistry (5.310) introduces experimental chemistry for students requiring a chemistry laboratory who are not majoring in chemistry. Students must have completed general chemistry (5.111) and have completed or be concurrently enrolled in the first semester of organic chemistry (5.12). The course covers principles and applications of chemical laboratory techniques, including preparation and analysis of chemical materials, measurement of pH, gas and liquid chromatography, visible-ultraviolet spectrophotometry, infrared spectroscopy, kinetics, data analysis, and elementary synthesis.

- Abstract: Students are introduced to acids and bases, and the environmental problem of acid rain. They explore ways to use indicators to distinguish between acids and bases. Students also conduct a simple experiment to model and discuss the harmful effects of acid rain on our living and non-living environment, as well as how engineers address acid rain. In an associated literacy activity, students learn how persuasive techniques are used to develop an argument, and create an environmental case study.
