What is neutral? pH scale: 0-14. 7 is nuetral Science Concepts Review Science Concepts Review What is involuntary and voluntary muscle? And where are they found? Involuntary – no control – digestive system Voluntary – you can control – arms, legs, etc Science Concepts Review What is an ion? How is an ion formed? How are bonds formed? Lose, gain, share electrons Electrons are negative Science Concepts Review What are the steps in the scientific method? Question – Hypothesis – Research – Materials List - Procedures – Test hypothesis – Collect data – analyze results - Conclusions Science Concepts Review Work = Force x distance Joules = Newtons x meters Machines make work easier by changing the direction, amount, or speed of the force applied Science Concepts Review What are the parts of a lever? Input force, output force, fulcrum What situation allows you to move the weight with the least amount of force? Science Concepts Review Science Concepts Review What is the mechanical advantage of the lever? Mechanical advantage equals the output force divided by the input force. Science Concepts Review What happens to the magnetism of a bar magnet when it is split into two pieces? It forms 2 magnets – each with a N and S pole Science Concepts Review How much of earth’s surface is land? How much is water? 70% water Science Concepts Review What are the parts of an atom? Protons, neutrons, electrons Where is most of the mass of an atom located? The Nucleus–protons and neutrons Science Concepts Review What is the basic unit of a living thing? The Cell Science Concepts Review What are the next levels of organization as complexity increases? Cells – tissues – organs – organ systems Science Concepts Review What are some common ways to improve the accuracy of experimental procedures? Eliminate human error – observation, stopwatches, opinion Science Concepts Review What are the different types of faults where tectonic plates come together? Convergent, divergent, transform Science Concepts Review What does “ologist” mean? List some scientists and what they study?

Focus What is the point on the surface above the focus called? Epicenter Science Concepts Review What is acceleration? Rate of change of velocity Science Concepts Review How are balanced and unbalanced forces related to acceleration? Unbalanced forces always cause a change in motion If forces are balanced there is no change in the motion of an object Science Concepts Review What is meant by renewable resources? Examples? Renewable are replaceable in a timely manner. Hydro, wind, geothermal, solar, biomass Science Concepts Review What are nonrenewable resources? Examples? Nonrenewable are not easily replaced. Fossil fuels, nuclear, Science Concepts Review What is a planet’s period of revolution? Time for 1 revolution around the sun – 1 year Science Concepts Review Which planet has the longest year? The planet with the longest orbit and is farthest from the sun. M_V_E_M_J_S_U_N_P Science Concepts Review Nutrients are always being transported in and out of the cell. What is the flow of water into the cell called? Osmosis Science Concepts Review What is photosynthesis? Food production from light energy What is respiration? Gas exchange - breathing Science Concepts Review What is meiosis? Cell division when the cells and chromosomes split and each cell has half the original number of chromosomes – the sex cells.
