39Answers 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 doesA 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
40Answers 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.”

48Answers to 1.2 Section Review Things that are commonly measured byMass: 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.

71Chapter 1 Math Skills 2. Determine the relationship between units. Section 2 The Way Science WorksMath Skills2. Determine the relationship between units.Looking at the table of prefixes used for small measurements, you can find that 1 cm = 0.01 m.This also means that 1 m = 100 cm.You will multiply because you are converting from a larger unit (meters) to a smaller unit (centimeters)3. Write the equation for the conversion.length in cm = m

81SR 1.3 p26 #’s1-4 Line graphs are best for continuous changes. Pie charts show the parts of a whole. An example is the percentages of types of CD’s that make up a collectionAccuracy is how close a measurement is to being correct. Precision is how small the smallest unit of measurement is.The correct answer is that both weigh the same. A reason for an incorrect answer might be that the batch of feathers would be much lighter than the same-sized piece of lead.

129Chapter 1Section 3 Organizing DataMath SkillsWriting Scientific Notation The adult human heart pumps about L of blood each day. Write this value in scientific notation.1. List the given and unknown values.Given: volume, V = LUnknown: volume, V = ? x 10? L
130Chapter 1 Math Skills, continued Section 3 Organizing DataMath Skills, continued2. Write the form for scientific notation.V = ? x 10? L3. Insert the known values into the form, and solve.First find the largest power of 10 that will divide into the known value and leave one digit before the decimal point. You get 1.8 if you divide into L.So, L can be written as (1.8 x ) L
131Chapter 1 Math Skills, continued Then write 10 000 as a power of 10. Section 3 Organizing DataMath Skills, continuedThen write as a power of 10.Because = 104, you can write L as 1.8 x 104 L.V = 1.8 x 104 L
132Chapter 1Section 3 Organizing DataMath SkillsUsing Scientific Notation Your state plans to buy a rectangular tract of land measuring 5.36 x 103 m by 1.38 x 104 m to establish a nature preserve. What is the area of this tract in square meters?1. List the given and unknown values.Given: length, l = 1.38 x 104 mwidth, w = 5.36 x 103 mUnknown: area, A = ? m2
133Chapter 1 Math Skills, continued 2. Write the equation for area. Section 3 Organizing DataMath Skills, continued2. Write the equation for area.A = l w3. Insert the known values into the equation, and solve.A = (1.38 104 m) (5.36 103 m)Regroup the values and units as follows.A = (1.38 5.36) (104 103) (m m)When multiplying, add the powers of 10.A = (1.38 5.35) (104+3) (m m)A = 107 m2A = 7.40 107 m2
134Chapter 1Section 3 Organizing DataMath SkillsSignificant Figures Calculate the volume of a room that is m high, 4.25 m wide, and 5.75 m long.

138Scientific 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 LThe 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 spacesm = 2.1 x 10-6 m

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.
172Chapter 1 Reading Skills Standardized Test PrepReading SkillsTwo 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.
