CHAPTER 2 SCIENCE AND MEASUREMENT2.2 Distance, Time, and SpeedImagine you are in a submarine exploring the deepest part of the ocean. Combine the relationships with what you know to find what you are 4 asked for. There must be some natural law that explains what supported by a lot of evidence causes the coffee to cool. Explain, and use a very simple math problem to prove your answer. For example, 20 feet is a value.motion variable Saying a race car, runner, or plane is fast is not enough to accurately describe its speed scientifically. Why do you think balsa wood, 2 cm ?Mass = rather than oak or ash, is commonly used for building models? When the orbiter reached Mars on the 23rd of September in 1999, its guidance system brought it too close to the surface, and the orbiter was destroyed by atmospheric friction. Relationships: distance = speed time 4. that can be seen independently byAn example of Scientific evidence may include numbers, tables, graphs, words, others if they repeat the same scientific pictures, sound recordings, or other information. 100 200 What you will do Applying your knowledge 1. CPO looks so awesome, but WOW, it's expensive! Other metric units for speed are cm per second (cm/s) and meters per second (m/s). aS. This connection is precisely what Nathan Busenitz, Dean Why cant you use the SI conversion tool to convert from SI to 5. One has a mass of 20 grams and its dimensions are 2 cm4 cm1 cm. The CPO Lab simplified for better student understanding. For example, the density Cork 440 0.12 of aluminum is 2,700 kg/m3. Then try to solve the One measures 75.5 seconds. Section 2.2Review Science Skills Chapter 2 SOLVE IT! is used to communicate different quantities. Format Hardcover. Math Success Toolkit . You melt a pan of ice into water by heating it up on a stove. Record the mass in the table in the an unsharpened pencil first try column. One cubic centimeter (cm3) is the same volume as one . Describe 7. The density of a liquid is lower because the atoms are not packed as tightly as in a solid. evidence? Julie, a third grade student, believes that the moon disappears on wood. Brick is heavy, or high density, and therefore contains a lot more mass per cubic centimeter than foam. Volume vs. mass Can you think of something that has a relatively small amount of mass, but takes up quite a bit of space? Reviewed in the United States on October 8, 2012. 2. Conversion factors are translators between one language of units and another. Galileos sketches describe in detail what he actually saw through the telescope. For example, your weight in science means the force of gravity pulling on the mass of your body. 6. The name for a pure form of matter that cannot be chemically broken down is ____. When water molecules freeze into ice crystals, they form a pattern that has an unusually large amount of empty space.

Does what other people think qualify as scientific evidence? Chapter 2 Science Skills VOCABULARY 2.3 Graphing graph a visual representation of data Mass, volume, and density are common properties of matter that we measure. $14.99 $ 14. Reaumers curiosity and certain days every month. All matter has mass. Each different theory is then compared with the evidence. Copy Table2.1 and fill in the missing boxes. calculated the mass from the Volume (liquids) ? An average adult has a mass of about 55 kilograms. Instead of theory, scientists use the word hypothesis to comparison with scientific describe a possible explanation for a scientific mystery. The detective searches for evidence and clues that through inquiry. a sheet of notebook paper a compact disc d. Estimate your mass in grams and in kilograms. e. The group averages are quite different. District subscription .

Even one single piece of evidence that does not agree with a theory will force scientists to return to step one. The density of air is lower, of coursemuch aluminum, water, and air expressed in grams per milliliter (1 mL = 1 cm3). Calculate your error in estimating the mass of the 10 gram 3. There was a problem loading your book clubs. Sometimes this includes numbers or values. 4. We have new and used copies available, in 0 edition - starting at $8.18. Scientists observe nature, then develop or revise hypotheses scientific about how things work. things out are all ways to help. A graph is a visual way to organize data. a.

Suppose a small block of aluminum with a mass of 10.8 grams is used to make a soda can (Figure2.12). The diagram in Figure 2.11 shows the four steps. a. She will try what she knows: biting the lid, pulling on it, shaking the jar, dropping it, until, by chance, of learning that begins with a she twists the lid. There are three ways to arrange the variables to find either distance, time, or speed. Certificates show that . a. Chapter 1 Measurement Chapter 1Assessment Section 1.3 Vocabulary 9. If your solution is9. At the speeds he was traveling, the car also had to besafe so safety features were designed such as roll-cage protection, a safetyharness, and an energy-absorbing steering column.How did his car reach such high speeds without using a motor?

Ipe (pronounced ee-pay) is a Brazilian hardwood that can be used as a durable (and expensive!) Holt Science & Technology Physical Science. The fast bicycle (bottom) moves 3 meters each second, while the slow bicycle (top) moves only 1 meter each second. What information are you given? , Language 11. Dr. Wile suggests that the student keep a science notebook. Foam is light and airy, or low density, and even a large volume of foam has very little mass. world (Figure 2.2).

The Scientific Method In the Middle Ages, people thought the Sun, stars, and planets circled Earth which sat in the center. a. Miguel is told that hot objects, like a cup of coffee, cool off when left on the table in a cooler room. from information collected in the present. Constant means does not change, so constant speed is speed that does not change. Each page of these scaffolded notes represents a new section of from the text, Earth Science, CPO Science, 2012. Please try again. You may need conversion factors to change units. The piece of wood shown above has a mass of 20 grams. One cubic centimeter is the same volume as one milliliter. 3. This requirement means not all hypotheses can be considered transferred to the air in the room. All SI units use a common set of prefixes. How are to measure a wood block. The distance between two cities is 300 kilometers.
