In Grade 8, students deepen their understanding of the different forms of energy by describing how the energy transferred affects, or is affected by, objects.
This unit has six modules. The first two modules discuss the effects of energy at the macroscopic level while the next four modules tackle these effects at the particle level. Module 1 focuses on the idea that if a net or unbalanced force acts on an object, the motion of the object will change.
Forces unit study guide answer key
Module 2 picks up this idea and explains how the application of force can do work on an object with a corresponding transfer of energy. Module 3 describes the effects of heat on objects involved in energy transfer and explains these effects at the particle level.
Module 4 deals with how energy affects the movement of charges in electrical circuits. Module 5 discusses how energy propagates through solids, liquids, and gases. It also describes how the speed of the energy transferred varies with some factors, such as temperature. Module 6 describes how the different colors of light differ in terms of their frequency and energy. Most of the topics in this module are dealt with qualitatively in order for students to have a basic understanding of the concepts.
Some tasks include measurements and computations in order to illustrate the relationship among quantities. Through the activities included in each module, it is also aimed to make students gain interest in these topics and motivate them to learn more in the succeeding grade levels. The effects are manifested in the changes that objects undergo. For example, energy can cause changes in the motion of objects, particles, or charges. It can also cause changes in some properties of matter such as temperature.
The amount of change depends on the amount of energy transferred. They will describe the effects of forces on an object and determine the relationship between the net force acting on an object and its acceleration due to this force. Key questions for this module Do forces always result in motion? What are the conditions for an object to stay at rest, to keep moving at constant velocity, or to move with increasing velocity? How is force related to acceleration? This module aims to address the following misconceptions related to force and motion: 1.
If an object stays at rest, there is no force acting upon it. An object continues to move at constant velocity because a constant force acts on it.
If the speed of an object increases, its acceleration also increases. Objects move because they have a force; they stop when their force is already used up. Why are some objects faster than the others?
Note that there are no correct or wrong answers yet at this point. Just take note of their answers and go back to some of them after they finish the module.

An object in motion will stay in motion at the same speed and in the same direction unless acted n by an unbalanced force. Answer the following questions: Calculate the speed for the following problem: A motorcycle traveling the distance of meters in 16 seconds is traveling at what speed?
Explain what is happening in each graph below: E a.
In a constant but opposite direction c. What does the change in slope of a motion graph indicate? E The change in slope means that there is a change n direction, speed, or in both. A force is what changes the motion of an object.
E What is the unit of measurement for acceleration? What is the unit of measurement for force?
E Newtons N Inertia describes the tendency of an object to continue moving at the same speed and in the same direction. The more mass and object has, the more inertia it has, and the greater the force it takes to change its motion. E Regardless of the opening size of the ring and regardless of the mass of the marble, once the marble reached the opening, it traveled in its natural state closest to the state of inertia which was in a straight path since no force was acting on the marble.
Imagine that a car is approaching a curve in the road when it suddenly loses its steering and brakes. The area is flat and there is a guardrail on the road.
E Guardrail b. Explain why the car will take that path: The car will curve and not follow the path of inertia because the guardrail is a force acting on the car to make it change direction. Who wrote the laws of motion and how many laws are there? Which has more inertia: a bowling ball or a golf ball rolling at the same speed in the same direction?
Explain your answer. If there were no friction, the inertia of a moving object would keep it moving the same way forever or until a force changes its motion.Although we flexibly assess students using formative assessment all of the time, once we get to that anticipated "End of the Unit", it has been customary to give students a summative assessment to find out how much they got out of a unit.
If we give space in our classrooms for multiple paths to the destination, why not offer multiple tools to assess what they know? This lesson illustrates how to prepare for and administer choice in summative assessment. This lesson is linked to Forces and Motion Assessment Review - a lesson that helps students self-assess and review their performance on their assessment. Students generate different assessment types: oral, written, test, project, poster and speech are some exam ples students have experienced.
Together, we discuss the benefits pros and challenges cons of each assessment type. For an example, view: Pros and Cons of Assessment Choices. During the discussion, I steer students toward recognizing that assessment is necessary and doesn't need to feel stressful while also highlighting how different types of assessment may be better matched to different learning styles or preferences.
Teacher Note: This discussion can turn into a complain fest of epic proportions. It may help to set the tone by starting with a discussion about why assessment is an important part of scientific practice and the learning process. To help students explore their assessment choices, we review the Assessment Choices Student Handout together. As we read the three choices, students carefully consider the pros and cons of each choice based on the amount of time they have, an honest assessment of how much they understand, their ability to work independently and their learning style.
I explain that all assessment choices will be weighed equally for the grade and are due at the same time. The three choices are:. Choice 1 Unit Test: Review and complete a test based on the objectives for the unit. Choice 2 Online Portfolio: Complete a portfolio on your science Web site. You will choose an activity or artifact for each of the objectives for the unit that demonstrates your understanding of the topic and write a short reflection explaining how the artifact shows your understanding.
Choice 3 Experimental Design or Research Project: Plan and conduct an investigation from start to finish on one of the three topics:. For additional information on the three different assessment choices, visit this section's reflection: Designing Alternate Assessments. Here you will find all the support resources for each assessment.
While students are working on review activities following their Forces and Motion Assessment Review Checklistit is important to check in with each student to listen to their explanations about their assessment choice.
This conference is a pivotal strategy that allows a "gentle steering" of students toward a choice that is better suited to their unique skill set. One pitfall I encountered was an initial enthusiasm about the choices that require more independence portfolio and experimental design.
However, student enthusiasm waned once they realized they would need to invest time outside of class in those assessments. It is important to prevent having students avoid an assessment altogether! Teacher Note: I follow a specific pattern for each unit. At the end, students use the guide to self-assess their level of understanding.
The Forces and Motion Review Notes Student Handout and associated Forces and Motion Review Notes Answer Key are an additional review and self-assessment tool that is strategically designed to match the unit objectives.
Since there is a student need for learning how to study and help organizing their review activities, the Forces and Motion Assessment Review Checklist and Forces and Motion Review Stations Instructions are good strategies. Students are expected to use both class time and time at home to work through the review checklist. There are two levels of evaluation in this lesson:. For a moderate experimental design that could use some fine-tuning, view: Experimental Design Plan - Student Example.
In my class, several students pitched their own ideas. Here is a creative assessment designed by a student that was really above par:. Level 2 Students evaluate their own learning. For more information about this self and peer evaluation process, visit an associated lesson: Forces and Motion Assessment Review.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials.
