  1. Bell Ringers Intro to Physics

  2. Intro to Physics Nature of Science

  3. Draw the Venn Diagram & place the phrases in their appropriate circle • nonliving things • Speed • H2O • Energy • Combustion • Force • Gravity • Boiling Point • Attraction H2O Gravity Attraction Combustion Speed Energy Physics Chemistry nonliving things Boiling Point Force Intro to Physics: Day 1

  4. List 5safety violations in this picture Goggles not worn on eyes Girl is wearing open-toed shoes Backpack and books not put away Girl did not pull hair back thus caught on fire Boy drinking toxic substance Boy did not clean up chemical spill Chemical not to be disposed of in waste basket Intro to Physics: Day 2

  5. List 5 safe practices shown in this picture Goggles are on and over eyes Wearing closed toed shoes Handling hot glassware with oven mitts Safety apron is on and tied in back There are no spills on the lab table Lab area is clear of backpacks Intro to Physics: Day 3

  6. What is the scientific method? Organized set of investigation procedures used universally to solve problems. The difference between solving problems in science and real life situations is that we write the steps down. What are the parts of the scientific method? Observe the problem Collect Background Information Form a Hypothesis Experiment Conclusion Repeat Remember? Old Chickens Have Eggs Crack Regularly Intro to Physics: Day 4

  7. Graph Reading • What is the independent variable in this graph? • What is the dependent variable in this graph? • In 1996, what was the level of the Dow Jones? Intro to Physics: Day 6

  8. Select the graph that best represents the data in the data table & explain why? Graph 1 OR Graph 2 Intro to Physics: Day 7

  9. Convert 1.11 grams to Kg • G • U • E • S • S • -Write out the metric table in your notes with all the prefixes

  10. Convert 12.4 Hm to m • G • U • E • S • S

  11. 1. Convert 15.1 dg to g • G • U • E • S • S 2. Convert 275.3 cm to Dm

  12. Answer the following questions based on the graph. • What is the independent variable in this graph? • At 120 min. what is the temperature of the ice bags? • How long did it take the squid to reach 25 °C? 2 3 1

  13. 1. Convert 37oC to Kelvin • What mass in kgcorresponds to 25 cm3 G U E S S

  14. Look in your notes and find the definition of… Precision - Accuracy - Using the definition, which is dart board represent precise and accurate? Neither accurate or precise Precise and accurate 1 2 3 Precise, not accurate Intro to Physics: Day 7

  15. Using your book write down the definition of density. What are the units for density? • Why does ice float? • What is the formula for density? Ice is less dense than liquid water

  16. Calculating Density • Calculate the density of Object 1? • Calculate the density of Object 2? • Calculate the density of Object 3?

  17. Density Review • A liquid has a mass of 7.2 g and occupies a volume of 2.4 ml. What is the density? • G • U • E • S • S • List the liquids from highest density to lowest density • Determine which has higher density

  18. What is the metric system? A decimal system of units based on length, mass, and time. What is the standard unit of measurement? • Length = • Volume = • Mass = • Time = meters (m) liters (L) grams (g) seconds (s) Intro to Physics: Day 8

  19. List the as many prefixes as you can that is used in the metric system. Kilo - Hecto - Deka - Base Units (m, g, L, s) deci- centi- milli- Kids Hate Deans Because deans call moms Intro to Physics: Day 8

  20. Standards of Measurement Table Draw the table and fill in the missing blanks. Kelvin K time seconds mass g length meter liters L

  21. 1. How do we remember the prefixes for the metric system? What are the prefixes? Kids Hate Deans Because deans call moms • Kilo- • Hecto- • Deka- • Base • deci - • centi – • milli - 2. Q: If you have 1000 m how many Km do you have? A: 1 Km 3. Q: If you have 1000ms how many “s” do you have? A: 1 s
