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. ____ includes all the inventions and techniques humans have developed by applying science. Explain, using examples, how SI and English systems of measurement are both used in daily life in the United States. Follow these steps technique and you will be able to see a way to the answer most of the time. SCIENCE AND MEASUREMENT CHAPTER 2Comparing variables You cant Which is faster: 95 km/h or 75 mph? Mass What is the density of the candle? 280 kilometers in 4 hours. triple beam balance. 13. Use these relationships to Figure2.7: An electronic scale and a answer the following questions. Unlike book problems, design problems have many correct solutions limited only by your creativity, ingenuity, skill, and patience (Figure 2.12). Mass is a fundamental property of an object measured in kilograms (kg). Earth science involves the studies of geology, meteorology, astronomy, and oceanography. Never drop things onto a balance! (Hint: Dont forget to check the illustrations.) Use the letters E (energy) and M (matter) to identify each of the following:5. Constraints are limits on cost, weight, time, materials, size, or other things. For this reason, scientists define concepts like evidence force and weight very clearly. examples to support your explanation. Newtons First Law explains what happens when there is NO net force on an object. The school is 3 miles away from your house.2. That 100 cm/s means you can multiply or divide by a conversion factor without 3,600 s 1.609 km changing the actual quantity; you only change the unit.

Any hypothesis that correctly accounts for all of the evidence for Earth and the solar system that were from the observations and experiments is a potentially believed at different times in history. To calculate the overall star rating and percentage breakdown by star, we dont use a simple average. If not, start working with the relationships you you will be able to find the answer to a have and see where they lead. 1 kilogram). : Air (avg.) not the same, so this question has no sensible answer.Units are like Both 95 km/h and 75 mph are speeds per hour. How could you give a bottle of water more energy?8. Maybe you dont know what Figure 2.8: Different forms of the the number will be yet, but once you get everything arranged according to the rules, you can fill the boxes with the numbers that speed equation. When scientists need change, often with a numericalto communicate precise information they use variables. , Hardcover That means we only Table 2.2: Conversion factors languages need to convert kilometers to miles to find out which is faster. Dividing by 1,000 gives a density of 2.7 g/cm3. A bunch of bananas has a mass of about 1 kilogram.
