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.
An economy model planetarium. Moon, Earth and Venus globes are rotated, revolved separately by hand. The twilight zone ring enables young students to better understand the nature of dawn and dusk. Underarm chain drive keeps the North Pole pointing to Polaris, the North Star. Durable, colorful plastic with brass and steel parts. Complete quality planetarium at a low price.
The Solar System as seen from earth. This model shows the five planets and moon as Ptolemy described them in his famous book, "The Almagest". It describes accurately all the naked eye phenomena of our Solar System. The fact that most of the motions described by this geocentric system are incorrect cannot detract from the fact that to the unaided human eye all these incorrectly described motions appear correct. The use of the Ptolemaic model together with the Copernican model improves student understanding of the motions of the heavenly bodies. 14" high x 20" long. With fully-illustrated instruction book.

Developed by the same teacher who created our DNA Manipulatives kit, this package includes colorful, large DNA, mRNA, ribosome, tRNA and amino acid models that attach to the blackboard. Teachers use these models to simulate the protein synthesis process, and students are provided with smaller size models for hands-on learning about the process and key concepts. As part of the activities, each student is given a unique DNA sequence and is asked to identify the resulting amino acid sequence. Kit also includes an instructional CD. Adequate for a class size of 40 students with students working in groups of two.

In this step-by-step classroom project students examine and identify individual rock specimens. As each rock specimen is examined and identified, students progress toward the completion of their own rock reference charts. The Teacher's reference chart uses illustrations and actual specimens for students to consult as they identify unlabeled rock specimens. For grades 6-12.
The Edinburgh II 16" Blue Ocean Raised Relief Floor Standing World Globe sports clean, sophisticated lines, a gyro-matic full swing meridian which allows you to fully view the soft blue oceans and brightly colored landmasses.
