Simple Experiments ['sĭm-pəl] [ĕx-'pîr-ə-'mĕntz]
The use of our senses and instruments to test hypotheses about the physical world.

Experiments are a structured and controlled way to answer questions. Scientists do them to help us understand our world. They ask a question, set up a test where they can control the object, process or behavior they have a question about, then use their senses and instruments to carefully observe and measure what happens. Scientific instruments, like telescopes or microscopes, can make their senses more powerful. You can be a scientist by conducting your own simple experiments.
