 * What do you know about forces, energy, and motion? In this lesson, you will complete six short inquiries about the topics in this unit. The inquiries are designed to get you thinking about physical forces, energy transformations, and the motion of objects. The observations you make and the ideas you discuss in this lesson will prepare you for future inquiries in this module. **
 * 1) Perform a series of activities to investigate forces, energy transformations, and motion. **
 * 2) Observe, describe, and hypothesize about the physical phenomena you experiment within the activities. **
 * 3) Relate your observations to personal experiences. **

Lesson 2: The Force of Gravity Introduction- Objectives-
 * Think about jumping off the low or high board at the swimming pool. What forces are at work and what are they like? This is the first of several lessons in which you will investigate different forces. In this lesson, you will investigate a force that you experience everyday- the force of gravity. In the lessons that follow, you will investigate other forces-including friction, elastic forces, and magnetic forces. **
 * 1) Measure the weight of objects with different masses. **
 * 2) Describe how mass and weight (force of gravity) are related. **
 * 3) Use data tables and graphs to interpret data. **

Lesson 3: The Force of a Rubber Band Introduction- Objectives-
 * Trampolines are a lot of fun. What forces are at work as you bounce up and down on a trampoline? You just investigated one of these forces- gravity, in Lesson 2. In this lesson, you will investigate another force that makes it possible to have fun! **
 * 1) Describe the nature of elastic forces and how they act on objects. **
 * 2) Determine how the force a rubber band exerts is related to its stretch. **
 * 3) Use data tables and graphs to interpret data. **

 * [|Lesson 3 Lab questions/reflection questions/reading questions] **
 * In Lessons 2 and 3, you investigated the properties of gravity and elastic forces in rubber bands. In this lesson, you will explore another force- friction. Friction is another force you experience every day. People spend time, money, and effort to reduce it. You might be surprised to learn that friction is not always bad. It can be very helpful too. **
 * You will investigate the force of friction as you pull a wooden block at a constant speed across a surface. As you do so, you will investigate three variables- surface type, weight (load), and surface area (base area)- and determine how each affects the frictional force between the block and the surface. In each trial, you will change one variable and keep the other two the same. This method is an example of good experimental design. As in the previous inquiries, you will record observations, collect data, and draw conclusions based on what you discover about friction. Understanding friction will help you understand motion, which you will study later in this unit. **
 * 1) Observe the properties of sliding friction. **

How can you measure its motion? What forces are at work? These are questions that you will explore in this lesson and the lessons that follow. Understanding notion and forces makes it possible to predict where an object will be at some future time. This makes it possible to make planes fly, cars move, and even to send spacecraft to distant planets and keep them on course over billions of miles. In this lesson you will begin your investigation of motion by looking at how a steel ball moves. you will also begin to think about energy associated with moving objects. **
