CHAPTER 2 SCIENCE AND MEASUREMENTRelationships between distance, speed, and time Mixing up A common type of question in physics is: How far do you go if youdistance, speed, drive for two hours at a speed of 100 km/h? You know how to get speed from time and distance. Water is an Water is an exception to this rule.

Chapter 2 Science Skills Density of solids and liquids Material density Density is a property of material independent of quantity or shape. You can think of each letter as a box that will eventually hold a number. Such testing leads to continued development and refinement of theories to explain more and more different things. Objective evidence means the evidence should describe only what actually happened asconsidered exactly as possible. Your familys car probably shows speed in miles per hour (mph). Julies hypothesis. Follow these steps technique and you will be able to see a way to the answer most of the time. Fully write out the steps you follow.8. 7.

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. Measuring the You can measure the volume of liquids by pouring them into a graduated volume of liquids cylinder. The same mass of melted (liquid) they are jumbled up. The dimensional analysis method of unit conversion is sometimes Section 1.3 called unit canceling. Explain why this is a good name for 7. Chapter 1Measurement 25 (Figure2.7).

Give your own example. As coffee cools, its heat energy is or false. Imagine scientific method - a process chance a small child trying to open a jar. Chapter 2 Science SkillsFOR SAMPLE ONLY - NOT FOR CLASSROOM USE Mass and weight are different VOCABULARY Mass vs. weight We tend to use the terms mass and weight interchangeably, but they are weight a measure of the pulling not the same thing. If the life force is undetectable, that means no evidence can be collected that would prove whether it exists or not. Masses you will Ordinary objects tend to have masses between a few grams and a few consider in science hundred kilograms. 8.
