You're looking at the the best of the best chemistry kit! CHEM C3000 includes all of the components from CHEM C2000, plus more than 40 additional tools and chemicals, and over 100 additional experiments, for a total of more than 360 experiments. The full-color 176-page experiment manual is written at a more advanced level than the other CHEM set manuals. We would call it a textbook, but the manual is too much fun to make that comparison. CHEM C3000 has a hands-on approach to teaching chemistry, 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 high-school level chemistry.
