Intro to Physics: Day 2 List 5 List 5 safety violations in this picture 1.Goggles not worn on eyes 2.Girl is wearing open- toed shoes 3.Backpack and books not put away 4.Girl did not pull hair back thus caught on fire 5.Boy drinking toxic substance 6.Boy did not clean up chemical spill 7.Chemical not to be disposed of in waste basket

5
List 5 safe practices shown in this picture Intro to Physics: Day 3 1.Goggles are on and over eyes 2.Wearing closed toed shoes 3.Handling hot glassware with oven mitts 4.Safety apron is on and tied in back 5.There are no spills on the lab table 6.Lab area is clear of backpacks

6
What is the scientific method? What are the parts of 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. Intro to Physics: Day 4 Observe the problem Collect Background Information Experiment Conclusion Repeat Old Chickens Have Eggs Crack RegularlyRemember? Form a Hypothesis

7
Graph Reading 1. What is the independent variable in this graph? 2. What is the dependent variable in this graph? 3. In 1996, what was the level of the Dow Jones? Intro to Physics: Day 6

10
Convert 12.4 Hm to m G U E S

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

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

13
1. Convert 37 o C to Kelvin 2.What mass in kg corresponds to 25 cm 3 GUESSGUESS

14
Look in your notes and find the definition of… Intro to Physics: Day 7 Using the definition, which is dart board represent precise and accurate? 123 Precision - Accuracy - Neither accurate or precise Precise, not accurate Precise and accurate

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 ObjectInitial vol. (vi) Final vol. (vf) Mass 190 ml93.2 ml2 g 250 ml65 ml3 g 310 cl15 cl7.5 g 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 List the liquids from highest density to lowest density Determine which has higher density

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

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

20
