Branches of Science: Lesson for Kids

Instructor: Alexandra Owens

Alexandra has taught middle school science and has a master's degree in Math and Science Education.

Did you know that science can be broken down into several branches of study? These include physical science, life science, and earth science. Let's learn more about each and decide which is your favorite!

What Is Science?

Science is the study of the world around us using observations and experiments. It can be a fun way to explore the world and get your hands dirty. But did you know science also has something in common with ice cream? Just like ice cream, science can be broken down into many different flavors. Only in science, these 'flavors' are called branches. Just like you might have a favorite flavor of ice cream, many scientists choose to study a particular branch of science!

If you study physical science and chemistry, you may work mixing chemical and designing solutions.

What Are the Branches of Science?

Science can be broken down into three main branches: physical science, life science, and earth science. Each of these can be further broken down into more specific topics. Let's learn about some of each!

Physical Science

Physical science is the study of non-living things and the laws that describe them. You will not see any animals or plants in this branch of science. Here are some examples of what you would study:

  • Chemistry explores matter and how it interacts. This may include chemical reactions, discovering new elements, designing materials, or even creating fireworks!
  • Physics looks at the universe and the rules that explain how it works. In this field you may study gravity, rollercoasters, car collisions, or motion.
  • Astronomy is the investigation of outer space and the objects found there. You may study planets, stars, or other far away galaxies.

Life Science

Just like it sounds, life science is the study of living things. There are many, many fields in life science depending on what living thing you decide to study. There are specific fields for insects, fish, and even seaweed. A few include:

  • Biology is the large field of studying life. Here you can study all sorts of living things and how they interact with one another.
  • Botany is the study of plants. This may include trees, flowering plants, and non-flowering plants. In this field you may make measurements of populations, or determine a new food crop.
  • Zoology is the study of animals and their behavior. This doesn't necessarily mean you will work in the zoo. You may also study animals in the wild or a lab setting.

If you study biology, you may observe tiny living things under a microscope.
