This video segment adapted from NOVA illustrates why carbon is at the center of life on Earth. It also asks whether carbon-based life might exist on other planets.

This activity seeks to have students model the process of science by recording quantitative and qualitative attributes of reactants and products in three separate experiments with the purpose of examining the relationship between the original reactant(s) to the final product(s). Students record the mass and volume of reactants and products and independently calculate mathematical relationships between the reactant(s) and product(s). They also record their observations of any physical changes that occur.

This activity is an introductory activity where students observe the characteristics of ionic compounds and crystals They also work on making observations and writing hypotheses.

Read and learn about strong and weak Arrhenius bases. View the written formula and discover what certain solutions may be dissolved and which molecules can be transferred.

Listen to this audio book on Chapter 6, Oxidation-Reduction Reactions. View chapter maps, binary ionic compounds, memory aids, and examples of different chemical reactions.

Use this study guide after reading Chapter 6, Oxidation-Reduction Reaction, in An Introduction to Chemistry. The study guide gives questions and answers and makes sure that there is an excellent understanding about oxidation-reduction reactions.

This chemical reaction study guide provides a concept map, chapter goals, and answers to the chemical reactions chemistry chapter. A great review of the basic concepts from the detailed corresponding chapter.

This chapter provides detailed information on solutions. Learn why solutions form, how different structures react in solutions, and about gaseous solutions in liquids. Also find a comprehensive review section.

An elementary introduction to chemistry vocabulary, tools and concepts used in science curriculum.

Listen and view examples of unit conversions and unit analysis. Examine English to Metric and Metric to Metric conversion examples.

This is an introductory lab for Environmental Science, investigating the bulk density of soil and water holding capacity.

This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.

This activity is a classroom lab activity that demonstrates chemical change in a dramatic way using a few inexpensive, easily obtainable materials.

This activity is a classroom chemistry lab where students will test different cleaning methods that could be used in oil spills. They will see the effects how oil spills damage animals and the environment.

This activity is an extension to standard labs that have students generate a pH curve from strong acid/strong base data. Students are asked to predict and test how the the titration end point will shift when titrating vinegar (a weak acid) with NaOH (a strong base).

This activity is an inquiry where students will design an electrolytic cell that produces work in the form of lighting a bulb.

This classroom lab allows students to develop skills of the scientific method while exploring the characteristics of enzymes.

This activity is an inquiry based lab where students determine 3 ways to change the rate of the chemical reaction between hydrochloric acid and alka-seltzer.

This activity is a classroom investigation where students separate pigment in dyes in order to learn about mixtures and solutions. They use chromatography to design and experiment with a single variable to answer a question about which ink will separate the most - has the greatest variety of pigment.

This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.
