To understand speed we speed - the distance an object need to be more specific and define speed so we can measure it and give it a precise value. Reaumers curiosity and certain days every month. 6. Investigations: Physics: A First Course Hsu. 1. Weight is a force that depends on the pulling force of gravity and is measured in newtons (N). Suppose you drive 150 kilometers (km) in 1.5 hours (h). A career that uses science to design, create, and work with technology is ____. b. Enrique wonders what happens to hot objects if you remove them from the stove. This review assignment covers Chapters 14-16 in the CPO Science-Foundations of Physical Science textbook (includes page numbers!). Figure 2.1: The steps in learningTheories In the process of inquiry, the detective asks lots of questions related to the mystery. Section 1.2 Section 1.2 3. What is the speed of the duck swimming in the picture above if it takes 15 seconds to move the distance shown? 4. You have to use what you know to design a solution that solves the problem. As I thumbed through the magazine it was hard to imagine spending that much on one subject, though if I had the money to do that I would. International. Because evidence is so important in science, there are careful rules defining what counts as repeatable - describes evidence scientific evidence. This is a guided reading assignment for Chapter 14 of the CPO Science: Foundations of Physical Science textbook. The density of the aluminum can is called its average molecules relatively tightly packed. In order to compare speedsin different units (or any variables) they must be in the same units. If the life force is undetectable, that means no evidence can be collected that would prove whether it exists or not. One cubic centimeter (cm3) is the same volume as one .

V= m D 1. noticed that wasp nests were b. believed by a large number of reputable people. The density of air is lower, of coursemuch aluminum, water, and air expressed in grams per milliliter (1 mL = 1 cm3). In this section, we will focus graph of two variables thought to on creating and interpreting scatterplots (XY graphs). Arrange the following intervals of time from shortest to longest: conversions? : c. What is the mass, in kilograms, of a 100.-lb. 2.2 Determining Density 39 Convert to g/cm3. Holt Science & Technology Physical Science. Hardcover. Calculate the density of the steel in the hex nuts. Measuring the You can measure the volume of liquids by pouring them into a graduated volume of liquids cylinder. Look for words like constant or at rest. Like this book? Figure 2.5: Three different models 3. Galileos sketches are good scientific evidence because they are both objective and repeatable. 4. A connect-the-dots line graph is often used to show trends in data over time (Graph D). There are other types of graphs, but berelated scatterplots are the most useful for organizing and presenting physical science data.FOR SAMPLE ONLY - NOT FOR CLASSROOM USE Types of graphs Scatterplots, bar Most graphs are either scatterplots, bar, pie, or line graphs. they are the same distance (59 miles) That tells us we divide 95 by 1.609 to get 59 miles. 7. The way people came to understand the solar system is a good example of how new evidence leads to new and better theories (Figure 2.5).32 UNIT 1 THE PHYSICAL SCIENCES Masses you will Ordinary objects tend to have masses between a few grams and a few consider in science hundred kilograms. When describing scientific evidence, what is the meaning of the word repeatable?6. Solution: Density=1,500 g 1,700 mL=0.88 g/ml (answer should have only 2 significant digits) Your turn a. problem most of the time.38 UNIT 1 THE PHYSICAL SCIENCES CHAPTER 2 SCIENCE AND MEASUREMENTHow to solve science problems Physics Problem solving means using what you already know to figure outproblems something you want to know. Whether an object floats or sinks is related to the objects density. conversion problems is called a(n) . NASA discovered that the guidance software, instead of using the SI unit of newtons for force data, used the English unit of pounds instead. Figure2.10: The density of a steel nail material is the same as the density of a solid cube A total of 500 g of solid solder fills a volume ofsteel. ____ length of a baseball bat b. A meter stick with millimeters as its smallest graduation is used 11. begin inquiry into what heat really is.The theory of Before 1843, scientists believed a theory that heat was a kind of fluid caloric (like water) that flowed from hotter objects to colder objects. For example, a line graph of a stock price may change over time, but it is not the time that causes the change to happen. Never drop things onto a balance! When is Scientific evidence must be objective and repeatable. Dont forget to report the correct unit when you record science measurement data! To displace means to take the place of or to push aside. You can find the volume of an irregularly shaped object by putting it in water and measuring the amount of water displaced. Making a Heres how to use the displacement method to find the volume of a house displacement key. Integrated Science: An .

Instead, set things gently on the balance. A method of using conversion factors and unit canceling to solve accuracy mass significant a unit conversion problem is called . It is a careful and cautious way to build an evidence-based understanding of our natural world. a. Miguel is told that hot objects, like a cup of coffee, cool off when left on the table in a cooler room. Science Textbooks *May be used as a reference for class.

Here are the PowerPoint Presentations & a few Flash files available for most of the chapters: Chapter 1 - Motion. Weight is a force of gravity measure of the pulling force of gravity on an object. A graph is a visual way to organize data. Usually, the scientific definition is similar to the way you already use the word, but more exact. Use these relationships to Figure2.7: An electronic scale and a answer the following questions. The density of Liquids and gases are matter and have density. 15, CPO Acceleration Lab: Using a ramp, 2 photogates, a car, and a ramps, What is the Relationship Between Force and Motion? We want Figure 2.10: The speeds 95 km/hconversion to convert 95 kilometers to miles (Figure 2.10). Calculate your error in estimating on your second try. Third, the theory must be unique. ____ Your 15th birthday b.

The other measures 1 minute and additional problems below the 15.5 seconds. Chapter 5 - Energy & Power. Mass describes the amount of matter in an object. A 2.3-kg bag of flour has the same mass no matter where it is in the universe. You ride your bicycle at an average speed of 15 km/h for 2 hours. To go from g/cm3 to kg/m3, you multiply by 1,000. 2.2 Determining Density 37 Unknown Binding.

SCIENCE AND MEASUREMENT CHAPTER 2Scientific evidenceWhat counts as In science, the only way to know you are right is to compare what you objective - describes evidence scientific think against real evidence. How do you use the SI conversion tool to perform metric 3. The Scientific Method In the Middle Ages, people thought the Sun, stars, and planets circled Earth which sat in the center. The student e. The relationship v = d t relates what you are asked to find to what you are given. a ramp for 1 meter, and the other group had their toy travel across a flat surface. The air in your classroom has a density of about 0.001 grams per cubic centimeter (0.001 g/cm3) (Figure2.8). 2 nd edition from Marshall Cavendish Education. objects do tend to have more mass than small ones.
