Branches of Science

There are three main branches of science to consider when choosing a course of study.

1. Physical Science studies the nature and properties of energy and non living matter.

Including:

Physics - The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics.

Chemistry - The science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems.

Astronomy - The scientific study of matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena.

2. Earth Science studies the origin, composition, and physical features of the Earth.

Including:

Geology - The scientific study of the origin, history, and structure of the earth or the solid matter of a celestial body.

Oceanography- The scientific study of oceans, the life that inhabits them, and their physical characteristics, including the depth and extent of ocean waters, their movement and chemical makeup, and the topography and composition of the ocean floors. Oceanography also includes ocean exploration.

Paleontology - The scientific study of the forms of life existing in prehistoric or geologic times, as represented by the fossils of plants, animals, and other organisms.

Meteorology - The scientific study of the atmosphere and of atmospheric conditions, especially as they relate to weather and weather forecasting.

3. Life Science (Biology) studies the structural and functional organization of living organisms and their relationships to each other and the environment.

Including:

Botany - The scientific study of plants, including their growth, structure, physiology, reproduction, and pathology, as well as their economic use and cultivation by humans.

Zoology – The scientific study of animals and animal life, including the study of the structure, physiology, development, and classification of animals.

Genetics - The scientific study of the principles of heredity and the variation of inherited traits among related organisms.

Medicine - The scientific study or practice of diagnosing, treating, and preventing diseases or disorders of the body or mind of a person or animal.

Looking at the variety of topics here, you soon realize that no science curriculum can cover it all. Try to choose a variety of lessons that will touch on each of the branches of science, then dive into more detail with your child's favorites. So how should you go about teaching homeschool science?
