**Answers to Section 1.1 Review Odd**

Chemistry is the study of matter and its changes. Physics is the study of forces and energy and their interaction with matter. 3. A guess or opinion is usually an unsupported statement. A scientific theory is one that has been repeatedly tested through observations. 5. A law does not attempt to explain why something happens; a theory does A model is used to study or make predictions about the object or situation the model represents. They are also used when an object or situation is too complex. Answers will vary

40
**Answers to Section 1.1 Review Even**

2. Technology is the application of science. Improving technology involves someone finding a use for a scientific discovery. However some scientific discoveries cannot be made until the technology for making the necessary observations exist. 4. A scientific law states a repeated observation about nature. 6. Quantitative descriptions use numbers. Qualitative descriptions do not. 8. Instead of being disappointed Roetengen decided to experiment to find out more about his “failure.”

**Answers to 1.2 Section Review**

Things that are commonly measured by Mass: solid food items, people, and mail; Volume: liquid food items, gasoline, air flow (exhausts fans and a/c units); Length: rope, distance, height. Scientific method is similar to critical thinking in that both involve thinking about a problem and checking details. A hypothesis is a possible answer to a question that can be tested. An example: “I can pass the test if I study at least 5 hours.” No experiment should be called a failure because an experiment that has unexpected results provides a chance to learn something new. Even now, there are scientific theories which have not been verified. In some cases these theories cannot be tested because the tools do not yet exists. An SI base unit is a single unit while a derived unit is a combination fo the base units. Base units include: seconds, meters, kilograms, kelvin, amperes, moles, and candelas. Examples of derived units are meters cubed (m3) or the newton (N), which is a kg*m/s2 . It is much easier to determine which factor your experiment depends on if you only check one factor at a time. If you change more than one thing and something unexpected happens, you will not know what caused the result.

**Writing Numbers in Scientific Notation**

Chapter 1 Section 3 Organizing Data Writing Numbers in Scientific Notation Scientific notation is a method of expressing a quantity as a number multiplied by 10 to the appropriate power. Some powers of 10 and their decimal equivalents are shown to the right. Coon’s Rule: The power of 10 represents how far you move the decimal from its current position Positive powers move the decimal to the right Negative powers move the decimal to the left. The zero power doesn’t move the decimal at all. 103 = 1000 102 = 100 101 = 10 100 = 1 10-1 = 0.1 10-2 = 0.01 10-3 = 0.001 3.5 x 103 = 3500 3.5 x 10-3 =

**Scientific Notation Shortcuts**

One shortcut involves numbers larger than 9. Move the decimal point to the left and count the number of places it is moved until you get only one number to the left of the decimal. To change to 1.8 in the previous example, the decimal point is moved four places. The number of places the decimal is moved is the correct power of 10. L = 1.8 x 104 L The other shortcut is for numbers smaller than 1. When a quantity smaller than 1 is converted to scientific notation, the decimal moves to the right and the power of 10 is negative. Suppose an E. Coli bacterium is measured to be m long. To express this measurement in scientific notation, move the decimal point to the right six spaces m = 2.1 x 10-6 m

**Using Significant Figures Write in Note Section (Today’s Date)**

Precision: the degree of exactness of a measurement Sort these units of length from the least precise to the unit with the greatest precision. Centimeters Kilometers Megameters Nanometers Meters Millimeters Gigameters Micrometers Which tape measure would be more precise, the one marked to decameters or the one marked to decimeters? Significant figures: the digits in a measurement that are known with certainty Hint: Zero’s are only significant if they are sandwiched between other numbers Do 3 and then 4a. from handout Accuracy: the extent to which a measurement approaches the true value What if the decimeter tape had about 0.5 meters torn off. Which would suffer, its precision or its accuracy?

**Significant Figures Practice**

Round m, kg, and cm to four significant figures. Round m, cm, and kg to one less significant figure than they each have currently. Use the equation, A = l x w, to find the area of a rectangle that is 48.5 cm long and 3.77 cm wide. Round your answer to the correct number of significant figures. Use the equation, weight = mass x free-fall acceleration, to find the weight of a kg dog. Round your answer to the correct number of significant figures. 12.25 kg x 9.81 m/s2 = Multiply m x m x 8.7 m. Round your answer to the correct number of significant figures.

**Practice SI Units and Conversions Between them**

Convert 100 m, the length of a well-known track event, to kilometers. Convert 5.98 x 1024 kg, the mass of Earth, to milligrams, mg. If you reported how quickly energy was used, measuring energy in joules, J, and time in seconds, s, which unit would you use? Convert a force of N to units of g∙cm/s2. Convert the gravitation constant of x N∙m2/kg2 to N∙km2/g2

165
**Practice Converting Measurements**

In Canada, you pass a speed limit sign that says 75 km/h. How fast can you drive in mi/h? How many liters of milk are in 3.5 gal? How many meters long is a 100 yd football field? (Note that 1 yd = 3 ft.)

Chapter 1 Standardized Test Prep Understanding Concepts, continued 4. When designing a new airplane, experienced pilots use computer simulations to determine how changes from previous designs affect the plane’s handling in flight. What is the advantage of computer simulation over actually building the plane and having pilots test it in actual flight situations? Answer: The computer simulation provides a model of the new plane so that potential design problems can be corrected without risk to the pilots and without the expense of building an airplane that does not function well.

**Chapter 1 Reading Skills**

Standardized Test Prep Reading Skills Two thousand years ago Earth was believed to be unmoving and at the center of the universe. The moon, sun, each of the known planets, and all of the stars were believed to be located on the surfaces of rotating crystal spheres. Motion of the celestial objects could be predicted based on the complex movement of the spheres that had been determined using observations recorded over many years. 5. Demonstrate why this description of the universe was a useful model to ancient astronomers but not to present-day astronomers.
