This article provides a step-by-step lab preparation for students to make their own soap using sodium hydroxide. It covers the materials needed, safety precautions, and the process of saponification, in which fats and oils react with a base to form soap. In addition to detailed explanations, sample lab questions and answers are also provided.

Making your own slime with borax and PVA glue is a fun and educational experiment. This manual provides a step-by-step explanation, including required materials, safety precautions and the scientific theory behind the process. The experiment demonstrates polymerization and crosslinking, where borax acts as a crosslinker and turns the glue into elastic slime. The clear instructions allow students to learn and have fun in a safe way. Additionally, we answer questions about the role of borax, the effects of different amounts, and the use of other types of glue, providing a better understanding of the chemical reactions.

The elephant toothpaste experiment is a popular chemical demonstration in which hydrogen peroxide is broken down by a catalyst, resulting in spectacular foam production. This experiment is ideal for educational purposes and demonstrates how catalysts work. Materials include hydrogen peroxide (3% or 12%), liquid dish soap, dry yeast, food coloring, and warm water. Safety precautions, such as wearing gloves and goggles, are essential. The reaction produces a large amount of foam, making the experiment a fun and educational experience for children and adults.
