Fun Facts

  • Scientists change only one thing at a time in an experiment, like energy sources for cars.
  • Even kids can learn about the world by doing experiments, like how different liquids affect plant growth.
  • Comparing how fast different liquids break down candy is an example of a simple experiment.

Why Do We Need To Know About Definition Of Experiment

Learning about experiments helps us know how we find out new things in science.  This is important for creating new technology and improving health care. For example, Thomas Edison’s experiments gave us the light bulb, which we use all the time.  Dr. Marie Curie’s research on radioactivity helps in medicine and keeping people safe.

Doing experiments isn’t just for expert scientists.  It’s a key way for everyone to learn and come up with new ideas in all kinds of jobs. By doing experiments, like seeing why raisins move in soda or what happens when soap meets milk fat, we understand how things work around us. This helps people in many jobs, like protecting the environment or making new medicines.
