  1. YEAR END PROJECT By: Taylor Honaker

  2. Periodic table • Metals- a good conductor, shinny, (far left of the table) • Non-metals- opposite from metals, not shinny, not a good conductor • Transitional: type of metal that has a high melting point • Noble gasses: very stable, takes a lot for it to change, tasteless and odorless

  3. Scientific method • Research question: the question that is asked • Variables: IV- what you change DV- what happens as a result of what you change CV- what stays the same • Hypothesis: educated guess, if and then statement • Procedure: steps to complete your experiment • Conclusion: summary of your experiment

  4. Matter • Three types of matter: solid, liquid, and gas • Has mass and takes up space • Solid: tightly packed together, desk, chair, and book • Liquid: close together moving around touching, water, soda, milk • Gas: moving around far from each other, smoke, carbon and air • Freezing pt: liquid -> solid • Condensation: liquid -> gas • Sublimation: solid -> gas • Boling pt/evaporation: liquid -> gas • Melting pt: solid -> liquid • Deposition: gas -> solid

  5. Physical and chemical changes • Physical changes: when only the appearance changes- ripping paper, writing, spilling water, spilling paint, painting a picture. • chemical changes: when a new substance is formed- burning wood, burning paper, moldy bread, nail rusting, ash, vinegar and baking soda

  6. mixtures • Homogenous- when they are the same • Heterogeneous- when they are not the same solutions • When a substance is dissolved by another • Solvent- doing the dissolving • Solute- what’s being dissolved

  7. Physical properties • Malability- how well you can mold it- clay, snow play dough • Hardness- how hard an object is- diamond • Conductivity- how well heat and electricity moves through it- gold • Viscosity- how thick something is- blood, oil, sap • Solubility- how well an object dissolves in another- chalk in vinegar • Density- how thick and buoyant an object is MASS M D V VOLUME DENCITY

  8. Diagram electrons P-protons N-neutrons 2, 8, 8, 18, 18

  9. Ionic and covalent bounds • Ionic bounds- when atoms gain or lose electrons, happens between metals and non- metals, metals will ALWAYS lose there atoms, no more the 3 will be lost or gain • Covalent bounds- when electrons a shared between each other

  10. Newton's 3 laws • 1st- an object will stay in motion or still unless a force is applied to it • 2nd- the more mass an object has the more force you need to move is • 3rd- for ever action is an equal and opposite reaction

  11. Simple machines • Makes work easier for people • Wedge- anything that splits something • Pulley- uses to lift things • Screws- holds something together • Incline plane- something that moves something from low to high • Wheel and axle- wheel that sits on a axle • Lever- helps bring something up or down

  12. Waves • Where energy is moved from one place to another • Medium- anything and everything • Mechanical- needs a medium • Electromagnetic- doesn't need a medium • Infrasound- low pitch • Ultrasound- high pitch • Doppler affect- when a sound is near its loud but when far away its faint Trough Amplitude Wave length Crest

  13. Electromagnetic wave spectrum • A scale the tells the speed of the wave

  14. Steps to make lightning • Build up charge • Separation of charges • Relishing of charges

  15. Circuits • Simple- only one path for energy to flow • Parallel- many ways for it to flow Power source Switch Switch conductor conductor Power source Power device Power device Power source
