The Magic Scientist Dennis Regling aka Mr. Dennis

First Things First!

You probably know what an experiment is. When a scientist experiments, he or she tries to discover a new fact or idea. Sometimes they may try to prove something people already know or think they know. An idea that is believed to be true without having been tested is called a hypothesis. Scientists test hypotheses to see if they are really true. A chemist is a scientist who experiments with liquids, solids, and gases. When a liquid or solid is combined with another solid or liquid, a change may take place. This is called a chemical reaction.On this website, you will find many experiments that can be done with items that are easily found around the house or at the store. Just remember: a scientist watches his or her work carefully and thinks about what they are doing. Scientists do not trust their memories, so be sure to record your experiments in a notebook. Describe what you have done and what you observe. Before making up your mind or reaching a conclusion about an experiment, be sure about your observations. Be sure to consult with an adult first before performing any experiment.Experiments
