Enroll in CHEM C1000 and prepare for a lifetime of fascination with this essential science through 128 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 coloured markers on the chromatography racetrack to reveal their different colour 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-colour experiment manual guides aspiring young chemists through each of the 128 experiments. Ages 10 and up.

Fascinating Oscillating Reaction Kit

Bestel
Heeft levertijd (USA)
Make a solution and watch it change from colorless, to amber, to blue, and then back to colorless. Amazingly, the cycle repeats itself again and again! Perform experiments to learn how the reaction works and the chemistry behind the Briggs-Rausher oscillating reaction. No sulfuric acid is required. Materials needed but not included are 3% hydrogen peroxide and water. This kit is for 3 demonstrations only and is NOT the classroom kit from photo !
