  1. Physics (Science) is Everywhere Unit One We need to hand out the clickers

  2. Science is Everywhere • What are we going to do in Chemistry • Physical and Chemical Properties • Solids. Liquids, Gases • Gas Laws • Atomic Structure • Periodic Table • Bonding, Reactions • Acids and Bases • What are we going to do in Physics • Motion • Velocity, Acceleration • Forces, Newton’s Laws • Fluids • Work and Power • Energy • Electricity • Waves, Light, Color, Sound

  3. Science is Everywhere • SI units • Yes, it’s true, you are going to be taught metrics AGAIN. • Really, it’s not my fault • Gotta know the base units

  4. Science is Everywhere

  5. Science is Everywhere • Where did the metric system come from? • Why do we teach it every year?

  6. Science is Everywhere • Based on what number? • ___________ • Can you easily convert?? • YES!

  7. Science is Everywhere

  8. Science is Everywhere The Prefixes • The Prefixes

  9. Science is Everywhere • Did you catch the base units from before? • Careful—watch your mass (actual ) base unit

  10. Science is Everywhere • Convert 1 kilometer to meters • Watch me do it

  11. Science is Everywhere • Convert 15 grams to milligrams • Watch me do it

  12. Science is Everywhere • Convert 25 centiliters to hectoliters • Watch me do it

  13. Science is Everywhere • Now you do it. • Grab your clicker and let’s go!

  14. 2 hectacres to acres • 200 • 0.1

  15. 2) 1500 meters to kilometers • 1.5 • 0.1

  16. 5.79 meters to centimeters • 579 • 0.1

  17. 4892 milligrams to grams • 4.892 • 0.1

  18. 6.1 kiloliters to liters • 6100 • 0.1

  19. Science is Everywhere • Base units and derived units • What’s the difference

  20. Science is Everywhere • Factor label for conversions (dimensional analysis) • Have you seen this before?? • 10 dollars into quarters

  21. Science is Everywhere • Still easy, doing something you know… • 250 meters into kilometers (using factor label method)

  22. Science is Everywhere • Minutes in a year?

  23. Science is Everywhere • 30 m/s to km/hr?

  24. Science is Everywhere • Grab your clicker…… • Now you do the next one

  25. 36 g/ml to kg/l • 36 • 0.1

  26. 100 km/hr to m/s • 27.78 • 0.1

  27. I have a good grasp on converting? • Strongly Agree • Agree • Neutral • Disagree • Strongly Disagree

  28. Science is Everywhere • Best way to organize data? • This is for all you “visual” people!

  29. Science is Everywhere • Graphing • Bar • Pie • Line

  30. Science is Everywhere • Graphing • Bar, what does it show?

  31. Science is Everywhere • Graphing • Pie, why use here?

  32. Science is Everywhere • Graphing • The popular line graph

  33. You Got Skills? • Ah, the line graph!! • X-axis • Y-axis • Dependent variable • Independent variable

  34. Science is Everywhere

  35. Science is Everywhere

  36. Science is Everywhere • Slope of the line? • How do we find it?

  37. Science is Everywhere • Remember the Scientific Method?? • Yeah, yeah, moving on (three more slides and it will return) • Using models • Draw me a picture • More on this to come…..

  38. You Got Skills? Let’s See!!

  39. You Got Skills? • Science begins with curiosity and often ends with discovery • Many items are discovered by mistake

  40. You Got Skills? • Scientific Method • Observations • Hypothesis • Test hypothesis (revise if needed) • Conclusions • Theory • Law

  41. You Got Skills? • Hypothesis • Theory • Law

  42. You Got Skills? • Using models • What is a model? • Is it really complicated?? • Does it need to be some complicated thing?

  43. You Got Skills? • Scientific notation • Why would you want to do this?? • How often am I really going to need this?

  44. You got Skills? • Scientific Notation examples…..

  45. You got Skills? • How to put it in my calculator? • 6.02 23 = 6.02 x 1023 It’s above the number 7 2nd EE

  46. You Got Skills? • Significant Figures • Not that significant • Mostly used in chemistry • Must be aware, online homework answers use six digit rule

  47. You Got Skills? • Finding Area • length x width • Squared unit (cm2, m2) • Units must match!

  48. You Got Skills? • Finding Volume • length x width x height • Squared unit (cm3, m3) • Units must still match!

  49. You Got Skills? • Try these example problems. • Note: Now we will be timed for each question

  50. Find the area of a rectangle that is 20 cm on one side by 30 cm on the other. • 600 • 0.1
