Discover how fascinating the world is when you understand the remarkable reactions behind ordinary occurrences. CHEM C2000 includes everything in CHEM C1000 and more — with twice the tools and materials, and more than three times the experiments. Most notably, this kit introduces you to the alcohol burner for experiments that require heat, greatly expanding the number of experiments you can conduct. Experiment with filtering and separating mixtures, combustion, and electrochemical reactions. Learn how to work with indicators and stronger acids and bases. Explore elements and compounds, including the chemical and physical properties of water, carbon dioxide, oxygen, hydrogen, and carbon. Discover atoms and molecules. Inspect soaps and household cleaners. Experiment with various foods from the kitchen to learn about sugars, fats, and proteins. Investigate metals such as iron, copper, and aluminum. Learn about how chemistry is used in environmental protection and industry. After completing CHEM C2000, you will have experienced firsthand the most important topics in chemistry, creating an excellent foundation for later study of chemical equations and atomic structure. The 128-page, full-color manual guides aspiring young chemists through 250 experiments. The manual provides clear instructions for preparing and performing the experiments and explains the results. Thorough safety precautions and instructions ensure safe experimentation. Professional quality equipment helps you make the most of your chemistry experiments. Ages 11 and up.

CHEM C3000 is the ultimate chemistry set. This kit includes all of the components from CHEM C2000, plus dozens of additional tools and chemicals, and 100 additional experiments, for a total of more than 333 experiments. The 192-page, full-color experiment manual is written at a more advanced level than the other CHEM kit manuals. You could call it a textbook, but the manual is too much fun to make that comparison. CHEM C3000 has a similar hands-on approach to teaching chemistry as our other CHEM kits, but also teaches more advanced topics such as chemical equations, atomic structures, and the periodic table. These concepts are critical to continued study of chemistry. CHEM C3000 is an excellent preparation for highschool level chemistry. Ages 12 and up.
Study of the chemical composition of toothpastes. Students evaluate several toothpastes for percent of solids, pH, foam formation, abrasive action, specific substances. They use this data to make judgments about their effectiveness. Materials for 12 pairs of students. Grades 7-12.
Introduction to elements, compounds, and mixtures, along with changes that these substances undergo as well as the characteristics of some elements, symbols for elements, and structures that make up atoms. Common mixtures are separated by evaporation and chromatography . New compounds are formed and changes that indicate chemical reactions are observed. Reproducible manual that includes 10 activities/laboratories, vocabulary lists and definitions, and a complete answer key. Experiments include: Classes of Matter, Elements, Symbols for Elements, Atoms, Common Mixtures, Separation by Evaporation, Separation by Chromatography, and more. 24 Students in Groups. Materials needed but NOT included: goggles, tape. Grades 4-9.
Seven different solutions are combined in every possible combination and chemical properties are identified by observing their reaction with other solutions. Chemical reactions include gas production, color changes and formation of recipitates. Students use their information to identify 4 unknown solutions.
