There are only two ways to teach Science: to teach it as a unified subject or divide it into categories. Unified sounds good but can be overwhelming to students. Subatomic particles like electrons don’t divide themselves into disciplines according to how they behave. In Physics we study electrons in different ways from observing how they behave in Organic Chemistry as electrons generating electrical impulses. By the time they have traveled down nerves and crossed synapses and caused our muscles to move they have gone over into the study of Biology. In fact, a degree in electrical engineering is known as an EEE (electrical and electronics engineer) because electricity and electronics operate so differently on a large and a small scale.
To keep from overwhelming students on high school level and below the sciences are generally divided into different subject areas. In Jr High or Middle School they are simply taught as Physical Sciences and Life Sciences. In High School the subjects are usually broken down into Earth Science, Biology, Chemistry, and Physics. Interrelationships are rarely explored in detail because there is no time.
The question often asked about science is, how do you make these subjects Christian? In Life Science, you can emphasize the fact that God created all life, and it did not develop by evolution. We can also study God’s requirements for treating all life, animal, plant, and human. In the hard sciences (those that are testable in a laboratory setting), the Bible speaks just as clearly. “By faith we understand that the worlds were prepared by the Word of God, so that what is seen was not made out of things which are visible” (Heb 11:3 NASB).
The spiritual created the material. The supernatural can intervene in and change the material world. Job got boils from head to foot from no physical cause. Jesus walked on water and healed people born blind and lame. Elijah was taken up to heaven in a fiery chariot.
The material universe is finite, not infinite. Though God is in control, we are responsible as mangers. God will hold us accountable for the way we manage the material world. “Then God said, ‘Let Us make man in Our image, according to Our likeness; and let them rule over the fish of the sea and over the birds of the sky and over the cattle and over all the earth, and over every creeping thing that creeps on the earth” (Genesis 1:26)
The world is relatively young, less than 10,000 years old. It is going to be destroyed by act of God’s judgment because of man’s rebellion. Man cannot destroy the earth.The Bible demands that we have wisdom and skill in handling material possessions but we should not spend all our time efforts and energy developing these things. They are secondary to worshiping God. The material world is not to become our god. We should not become obsessed with seeking material possessions or how to manipulate the material world. How we handle science will determine the quality of our life here on earth. We are limited in what it can do to the material world and it is finite and temporary.
Science is constantly changing, more than any other field. Whatever curriculum a homeschooling family chooses it must be a modern, comprehensive textbook acknowledging the principles God has set forth.
