Enroll in CHEM C1000 and prepare for a lifetime of fascination with this essential science through 125 diverse experiments. Start with an introduction to the field of chemistry and famous chemists. Set up your lab space and learn how to safely handle the lab equipment and chemicals. Learn about indicators with litmus solution and write a secret message in invisible ink. Test the inks from your colored markers on the chromatography racetrack to reveal their different color components. Experiment with air pressure, surface tension, and the physical properties of fluids. Experiment with two well-known metals, iron and copper. Investigate carbon dioxide. Dissolve metals with electrochemical reactions. Explore water and its elements, saturated and unsaturated solutions, and crystals. Split water into hydrogen and oxygen with electrolysis, and form oxygen from hydrogen peroxide. Experiment with soaps, detergents, and emulsions of water and oil. Investigate chemistry in the kitchen by experimenting with sugar, honey, starch, eggs and proteins, fatty acids, and calcium. Begin to build a strong foundation in chemistry with exposure to a broad range of chemical phenomena and hands-on laboratory experiences. This kit provides clear instructions for preparing and performing the experiments, offers safety advice, offers explanations for the observed occurrences, and asks and answers questions about the results. Thorough safety precautions and instructions ensure safe experimentation. Professional quality equipment helps you make the most of your chemistry experiments. The 80-page, full-color experiment manual guides aspiring young chemists through each of the 125 experiments. Ages 10 and up.

Grow dozens of dazzling crystals and conduct 15 illuminating experiments with this classic science kit. Experiment with four chemically different crystals each with different properties, including potassium alum crystals that form regular octahedrons, rapidly growing sodium sulfate crystals, long needle-shaped sodium acetate crystals, and plaster which is made from gypsum crystals. Mold fun plaster shapes, including stars, lightning bolts, dolphins, and pyramids, and grow layers of crystals on them. Use dyes to form colored crystals, and mix the dyes to grow a rainbow of custom colored crystals. Display your crystal creations in a clear treasure chest with a locking lid. Mold your own geode ù a hollow rock with crystals growing inside ù and create a beautiful crystal cavern inside. Experiment with growing crystals rapidly and slowly, and observe how that affects the crystal structures. See if you can grow one giant crystal, and many small crystals on the surface of a rock. Measure how the crystallization of solids out of a solution, and the dissolution of crystals back into solution, affect the temperature of the solution. Learn about the energy of crystallization. Investigate solutions, crystallization, and the chemistry of crystal growing. Learn about the structures and geometries of different crystal shapes. This kit is thoroughly tested and safe: Over one million units of this kit have sold worldwide. A full-color, 32-page experiment manual guides your experiments in crystal chemistry and Earth science.

Construct circuits with colorful electric building blocks to learn about electricity and how electronic devices work. With the innovative snap-together blocks in the ElectronX building system, children eight and up can safely and easily begin experimenting with electronic circuits. These building blocks are specially designed to make learning electronics fun and accessible. Because the blocks are brightly colored and have unique shapes, it is easy to follow the assembly diagrams to construct functional circuits. And because the circuit symbols are printed directly onto the blocks, you can quickly become familiar with the symbols and learn how to read circuit diagrams. The fun building projects include an alternating blinker, a police siren, an ambulance siren, an alarm system, a light detector, a conductivity tester, a rain warning system, a timer, and logic circuits. The electronic components in this kit include capacitors, resistors, transistors, LEDs (light emitting diodes), a phototransistor, a switch, 30 contact blocks, cable blocks, a battery holder, a speaker, and a sound integrated circuit. The 64-page, full-color experiment manual guides you through 70 circuit building experiments with easy-to-follow diagrams. This kit provides kids with the tools and instructions they need to experiment with their own hands and learn firsthand how electronics work.

Create your own crystal geode — a round rock containing a crystal-filled cavity. First, cast a plaster geode shell in the mold and then fill it with a crystal-growing alum salt solution. The crystal solution contains an ultraviolet-luminous pigment that gets incorporated into the crystals as they form, resulting in a geode that glows in ultraviolet light. An ultraviolet flashlight with holder, as well as a display stand for the geode, are included. Display your beautiful specimen day and night! Learn about how crystals form and why the pigment glows under ultraviolet light.
