  1. 1. 8th Grade Science And these are but the outer fringe of his works; how faint the whisper we hear of him! Who then can understand the thunder of his power? Job 26:14 By Brittney and Jhenai
  2. 2. Matter For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. Colossians 1:16 All things visible and invisible are matter and were created through God. Has mass and takes up space. 3 different states solid, liquid, and gas. Everything is matter. Measured by the International System of Units.
  3. 3. Atoms & The Periodic Table For I know the plans I have for you, declares the Lord, plans to prosper you and not to harm you, plans to give you hope and a future. Jeremiah 29:11 God has plans for all of us. Atoms are made of smaller particles a nucleus, electrons, and protons. Atoms have an atomic number the number of protons in its nucleus. Atomic mass unit measures the particles in an atom. Periodic table made up of elements in a pattern. (increasing atomic mass)
  4. 4. Chemical Bonds Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken. Ecclesiastes 4:12 Chemical bonds can't be easily broken and neither can the bond between two people. Two types of chemical bonds ionic and covalent. Ionic bond attraction between two oppositely charged ions. Covalent bond chemical bond formed when two atoms share electrons.
  5. 5. Chemical Reactions Jesus Christ is the same yesterday and today and forever. Hebrews 13:8 Jesus stays the same always, but worldly objects do not. There are several observable characteristics of chemical reactions the production of new materials and a change in energy. When chemical bonds break down or new bonds form a chemical reaction occurs.
  6. 6. Acids & Bases Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world 1 John 4:1-3 We can know if something is from God by testing it. Acids substance that taste sour, reacts with metals and carbinates, and turns blue litmus paper red. Bases substance that tastes bitter, feels slippery, and turns red litmus paper blue. pH Scale expresses the concentration of hydrogen ions in a solution.
  7. 7. Energy For we are Gods handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do. Ephesians 2:10 We are created in God to do work and energy is the ability to do work. Energy the ability to do work or cause change. There are 6 major forms of energy mechanical, thermal, chemical, electrical, electromagnetic, and nuclear. Mechanical associated with motion or position. Thermal total energy of particles in a substance or material Chemical potential energy stored in chemical bonds. Electrical moving electric charges that produce electricity. Electromagnetic travels in waves. Nuclear stored in nucleus of an atom and release during nuclear reactions.
  8. 8. Thermal Energy I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! Revelations 3:15 We either have to be passionate for God or don't care, but not in between the two. Thermal energy total energy of all the particles of matter. Does not depend just on the temperature, it also depends on the arrangement of the particles.
  9. 9. Motion For in him we live and move and have our being. As some of your own poets have said, We are his offspring. Acts 17:28 God gave us life and the ability to move so we can use it to worship Him. An object is in motion when its distance from another object has changed. An object is in motion if it changes position relative to a reference point.
  10. 10. Forces Since you died with Christ to the elemental spiritual forces of this world, why, as though you still belonged to the world, do you submit to its rules: Colossians 2:20 God is the force driving us to do good in the world. Force a push or pull. Unbalanced force can cause an object to start moving, stop moving, or change direction. Balanced forces equal forces acting on one object in opposite directions.
  11. 11. Magnetism Let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. Hebrews 10:22 We are like magnets with God because we draw near to Him. Magnetism the attraction of a magnet for another object. Every magnet has two ends, each called a magnetic pole. Magnetic poles that repel each other that are alike. Magnetic poles that attract each other are unlike.
  12. 12. Electricity He gives strength to the weary and increases the power of the weak. Isaiah 40:29 God gives us power. Electric current the flow of charge through a material. Electric currents produce magnetic fields. Electric circuit a complete path through which electric charges can flow.
  13. 13. Sound Praise our God, all peoples, let the sound of his praise be heard; Psalms 66:8 God can hear our praises. Sound a disturbance that travels through a medium as a longitudinal wave. Loudness describes what you actually hear. Speed of sound depends on the elacticity, density, and temp of the medium.
  14. 14. Light I have come into the world as a light, so that no one who believes in me should stay in darkness. John 12:46 Jesus is our light and guides us through dark times. Light can be reflected, absorbed, or transmitted when it strikes an object. Opaque a material that reflects or absorbs all of the light that strikes it. Transparent material that transports light. Translucent materials scatter light as it passes through.
