CHEM C2000 contains all the experiments of CHEM C1000, plus 176 more, for a total of 251 different experiments! After gaining the introductory lab experience from the experiments in the CHEM C1000 portion of the kit, more advanced tools, such as an alcohol burner, are introduced for more complex experiments. Young chemists separate mixtures, perform experiments with heat, investigate chemistry in cooking and cleaning, and discover fascinating new chemicals that fizz, shine, bubble, change color and even glow in the dark! Ages 11 and up; 96-page Manual; 251 Experiments. From Thames & Kosmos.
