Science demonstrations are visual presentations that illustrate scientific principles or concepts. They often involve experiments or activities that showcase how things work in the natural world. These demonstrations can be performed in classrooms, science fairs, or public events to engage audiences and enhance understanding of topics like physics, chemistry, and biology. Typically, science demonstrations use everyday materials or simple equipment to make complex ideas more accessible. For example, a volcano eruption demonstration can show chemical reactions, while a pendulum can illustrate concepts of motion and gravity. These engaging activities help spark curiosity and encourage further exploration of science.
