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 DENCITY VOLUME

8. Diagram P-protons N- neutrons electrons

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 Crest Wave length Amplitude

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

14. Steps to make lightning 1.Build up charge 2.Separation of charges 3.Relishing of charges

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