How to Test for Starch
Starch tests are used to detect the presence of starch in leaves, foods, and liquids. The process is easy and can quickly tell you if a leaf has undergone photosynthesis by its starch levels or if a food or liquid contains starch. Using iodine to test for starch is a simple way to engage your students in a classroom experiment or create an educational afternoon at home.

How to Use the Newton's Cradle
The Newton’s Cradle is a device that doubles as a desk ornament and a tool for explaining the basic foundations of physics. It is constructed by mounting a series of balls on strings to a common bar. Usually, 5 balls are present, and when one is allowed to hit the others, energy is transferred from one end to the other. Whether you are a teacher, a student, or just a curious person, you

How to Make a Liquid Into a Solid
Matter exists in three basic states: solid, liquid, and gas. Through freezing, crystallization, polymerization, and evaporation you can change the state of a solution or compound from liquid to solid. These experiments are easy to do at home, and some even result in something edible! Just remember to get an adult to help you with heating liquids and moving hot containers.

How to Explain Acids and Bases to Kids
If you’ve got a little chemist in your house, teaching them about acids and bases is a fun and fascinating project. Since acids and bases are everyday substances, it’s easy to make the concepts relatable. You can discuss things that help kids understand acids and bases (such as the pH scale), but it’s also possible to make your very own indicator at home. Use this indicator to have kids
