This activity is a physics lab to detect a magnet's field.
In this video from NOVA scienceNOW, learn how scientists detect potential signs of life on distant planets.
Students determine the energy efficiency of different methods of heating substances in the lab and then assess the economic and environmental costs.

This activity is an inquiry lab where students observe the effects of temperature change on nitrogen dioxide gas, a common component of polluted air, to determine its color.
In this field lab activity, students will determine the density, pH and water content of prairie soil, transition soil, woods soil, and riverbed soil and compare their findings.
The Developmental and Reproductive Toxicology and Environmental Teratology Information Center (DART/ ETIC) Database is made available by the National Library of Medicine's Toxicology Data Network. The database contains over 100,000 current and earlier literature citations covering teratology and other aspects of developmental and reproductive toxicology. Users may search the database by subject, title words, chemical name, Chemical Abstracts Service Registry Number, and author. The Web site also includes a useful help page and sample record for familiarizing oneself with the database.
An expert describes the carbon composition of diamonds, as well as the conditions necessary for diamond formation in this video segment from Nature.
This Nature video offers an introduction to the socio-economic value of diamonds.
Descripción del curso:
El "Manual de técnicas de laboratorio digital" desarrollado por el MIT, es una serie de videos diseñados para ayudar al alumno a prepararse para sus prácticas de laboratorio de Química Orgánica. Cada video proporciona una demostración detallada de una técnica de laboratorio, así como información y consejos útiles. Estos videos están pensados para complementar, y no reemplazar, el manual de laboratorio del alumno y los guiones de prácticas. De hecho, se beneficiará más de ver los videos si ya ha leído sus guiones.
The "Digital Lab Techniques Manual" is a series of videos designed to help you prepare for your chemistry laboratory class. Each video provides a detailed demonstration of a common laboratory technique, as well as helpful tips and information. These videos are meant to supplement, and not replace, your lab manual and assigned reading. In fact, you will most benefit from watching the videos if you have already read the appropriate background information. To be a great experimentalist, you must understand both theory and technique! If you have questions about what you see, make sure to ask your TA or your instructor.

Units... some may say they are usless. However units are very important and fundementally they provide meaning to numbers. So since you are learning chemistry and chemist love units you may just want to jump on the unit train. This module will go over one of the most effective tools to converting units, dimensional analysis.At the end of the module you should be able to...Convert between unit perfixes.Utilize dimensional anlysis to convert between two units.

This activity illustrates the carbon cycle using an age-appropriate hook, and it includes thorough discussion and hands-on experimentation. Students learn about the geological (ancient) carbon cycle; they investigate the role of dinosaurs in the carbon cycle, and the eventual storage of carbon in the form of chalk. Students discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth. Finally, they may extend their knowledge to the concept of global warming and how engineers are working to understand the carbon cycle and reduce harmful carbon dioxide emissions.
This activity is a field investigation where students will observe three areas with high sensitivity to pollution, and test water quality in two of the locations.
This activity is a guided inquiry on the density of two liquids and salt. Students will then create their own experiment to back their findings.
The purpose of this resource is to use a land cover type map to make environmentally sound decisions.
This lab activity shows students the Law of Conservation of Matter and intermolecular forces by having them dissolve packing peanuts in acetone.
This activity is a guided inquiry where students will investigate if water molecules have any space between them.
This lab introduces basic chemistry concepts in molecular interactions, measurements, prediction, and critical thinking.
In this interactive activity from the Building Big Web site, think like an engineer and use your knowledge of dome design to match the right type of dome to the right location in a fictitious city.
Explore tunneling splitting in double well potentials. This classic problem describes many physical systems, including covalent bonds, Josephson junctions, and two-state systems such as spin 1/2 particles and ammonia molecules.
