Hard science facts for kids
Hard science is a type of science that uses careful observation, experiments, and often mathematics to gain knowledge. In hard science, experiments must be reproducible. This means if someone does the same experiment again, they should get the same results. Also, in hard sciences, there is usually a strong agreement among scientists about what is known for sure. This is different from soft sciences. Hard sciences also tend to have a widely accepted main theory or way of looking at the world.

What Are Hard Sciences?
Hard sciences are subjects that study the natural world. They focus on things that can be measured and tested in a very clear way. These sciences often use tools and methods that give very precise answers.
How Are Hard Sciences Different?
The main difference is how reliable and consistent the results are. In hard sciences, if you follow the same steps, you expect the same outcome every time. This makes the knowledge gained very strong and dependable.
Why Are Experiments Important?
Experiments in hard science are designed to be very specific. Scientists try to control everything so that only one thing changes at a time. This helps them understand cause and effect clearly. Because the results can be repeated by anyone, the findings are considered very strong evidence.
Examples of Hard Sciences
Many subjects fall under hard science. These are often called the natural sciences because they explore the natural world around us.
Exploring Natural Sciences
- Physics studies energy, force, motion, and how the universe works.
- Chemistry looks at what things are made of and how they react with each other.
- Biology is the study of living things, from tiny cells to large animals and plants.
- Geology explores the Earth, its rocks, and how it changes over time.
- Astronomy is the study of stars, planets, and everything in space.
- Botany focuses specifically on plants and plant life.
What Are Soft Sciences?
Soft sciences are usually the social sciences. These sciences study human behavior and societies. They are called "soft" because it's often harder to get the exact same results every time.
How Are Soft Sciences Different?
In soft sciences, things can be done more than once, but the results might be very different each time. This is because people and societies are complex and can change their behavior. Also, there can be big disagreements among experts about what is true or the best way to understand things.
Why Do Results Vary?
Imagine studying how people react to a new law. Different groups of people might react in different ways. Their feelings, past experiences, and current situations can all affect their response. It's hard to control all these factors in an experiment like you would in physics or chemistry.
Examples of Soft Sciences
- History studies past events and how they shaped the world.
- Sociology looks at how people live together in groups and societies.
- Political science examines how governments work and how power is used.
Hard and Soft Sciences: A Mix?
Some areas of study can be a mix of both hard and soft science. For example, parts of psychology can be considered hard science. This is especially true for areas that study how our brains process information, like perception (how we see, hear, and feel things). These areas often use experiments that can be repeated and give consistent results.
