Catechisms
What is science?
Science is the study of God’s revelation in the natural world.
What are the three basic things the universe is composed of?
The universe is composed of matter, energy and intelligence.
What is a force?
A force is a push or a pull.
What are the two main ways we know truth?
Direct observation and revelation from God
What are ions and how do they form?
Ions are atoms that have a net charge. Ions form when atoms gain or lose electrons.
What is truth?
Truth is the way things really are. Truth never changes. Truth is communicated to us by revelation from God or by direct observation.
How are the three basic particles in atoms organized?
The protons and neutrons are located in the nucleus of the atom. The electrons are located in orbitals according to how much energy they have.
What are the three types of fields?
The three fields are the gravitational field, the electrical field, and the magnetic field.
Knowledge about God and creation that is accessible through nature and the universe is which type of divine revelation?
General Revelation
What is the difference between a pure substance and a mixture?
Pure substances are atoms that are chemically bonded together. Mixtures are atoms that are not chemically bonded together and can be separated by physical means.
What is the Law of Conservation of Energy?
The Law of Conservation of Energy states that energy can neither be created or destroyed, only changed in form.
What are the four phases of matter?
Solid, liquid, gas, and plasma
What is a magnetic pole?
A magnetic pole is one end of a magnet, identified as either north or south.
The knowledge revealed directly by God, often through sacred texts or religious experiences is which type of divine revelation?
Special Revelation
What is the difference between heterogeneous and homogeneous mixtures?
In heterogeneous mixtures, particles of different substances can be seen, either with the naked eye or under a microscope. In homogeneous mixtures, particles are uniformly mixed all the way down to the molecular level.
How do you determine the identity of an element?
The identity of an element is determined by the number of protons in the atoms’ nuclei.
What are three ways heat transfer?
Conduction, convection, and radiation
Which scientists proposed the Law of Universal Gravitation and the General Theory of Relativity?
Isaac Newton and Albert Einstein
Name the five main stages of the Cycle of Scientific Enterprise.
Theory, hypothesis, experiment, analysis, review
What are the two main goals that atoms pursue when they form compounds?
The first goal is to have a more desirable number of electrons. Atoms like to have a number of electrons that fills their orbitals. The second goal is to reside in an electrically neutral environment.
What are the four main forces in order from strongest to weakest?
The four main forces in order from strongest to weakest are strong nuclear force, electromagnetic force, weak nuclear force, and gravitational force.
List three types of energy.
Electromagnetic radiation, kinetic energy, gravitational potential energy, chemical potential energy, thermal energy, and nuclear energy
What are field lines?
Field lines are arrows that indicate the direction of a force that is present on an object place in the field.
Name a theory we have studied this year that has changed.
Atomic theory, gravitational theory, caloric theory
Describe ionic and covalent bonds.
Ionic bonds occur between metal and nonmetal atoms. This occurs when electrons are transferred between atoms—from metal to nonmetal—creating ions which form into a crystal lattice. Covalent bonds occur between nonmetals as the atoms share electrons and form molecules.
