Fifth Grade Science Pacing Guide – Revised April 2010 3 Vocabulary Resources Science Pacing Guide Time Frame: September/October Fifth Grade Unit 1: Forces and Motion (State Unit 1: Measuring Changes in Motion) Processes, Content Statements & Expectations (Disciplinary Knowledge) K-7 Standard P.FM: Develop an understanding that the position and/or motion of an object is relative to a point of reference. Understand forces affect the motion and speed of an object and that the net force on an object is the total of all of the forces acting on it. Understand the Earth pulls down on objects with a force called gravity. Develop an understanding that some forces are in direct contact with objects, while other forces are not in direct contact with objects. P.FM.M.2 Force Interactions – Some forces between objects act when the objects are in direct contact (touching), such as friction and air resistance, or when they are not in direct contact (not touching), such as magnetic force, electrical force, and gravitational force. P.FM.05.21 Distinguish between contact forces and non-contact forces. Essential Questions What is force? What types of forces are there? Where would you find forces in the world around you? What causes a change in motion? What are contact and non-contact forces? How do contact and non-contact forces change the motion of an object? P.FM.05.22 Demonstrate contact and noncontact forces to change the motion of an object. P.FM.M.3 Force – Forces have a magnitude and direction. Forces can be added. The net force on an object is the sum of all of the forces acting on the object. The speed and/or direction of motion of an object changes when a non-zero net force is applied to it. A balanced force on an object does not change the motion of the object (the object either remains at rest or continues to move at a constant speed in a straight line). Fifth Grade Science Pacing Guide – Revised April 2010 What happens when two forces act on the same object? What are balanced forces? Assessment Students conduct mini investigations using an inclined plane and a matchbox car to demonstrate forces. Have students chart their findings. Ask students to describe what starts objects in motion. Review the term force from their experiences or introduce the term if students are not yet familiar with the term. Students move a bowling ball using only a rubber mallet. Tapping the ball with the mallet can only move the ball, and the mallet cannot be kept in constant contact with the ball. This forces the students to observe the direction of the taps necessary to start the ball moving, keep the ball moving in a given direction, and to stop the ball and bring it to rest. The students identify the mallet as a contact force. 4 Vocabulary force balanced force change of direction change of motion change of speed force strength friction graph magnetic attraction magnetic repulsion mass relative position constant speed direction of motion gravitational force speed unbalanced force zero net force non-zero net force acceleration applied force kinetic energy mechanical motion Resources A lot of good websites with experiments to do in the classroom: http://classroom.jc-schools.net/sciunits/force.htm Create a rollercoaster, make sure that speed, mass, gravity and friction are appropriate. http://www.funderstanding.com/k12/ coaster/ A lot of links to great games and activities about forces and motion: http://www.learningscience.org/psc2 bmotionforces.htm Activity that has students get ready to teach topics to third graders: http://mrsdell.org/forcesandmotion/ (interactive website) State Companion document for ideas on inquiry/instructional strategies for each unit. http://tinyurl.com/dkd7y3 Processes, Content Statements & Expectations (Disciplinary Knowledge) P.FM.05.31 Describe what happens when two forces act on an object in the same or opposing directions.

Understand that fossils provide evidence that life forms have changed over time and were influenced by changes in environmental conditions. Understand that life forms either change (evolve) over time or risk extinction due to environmental changes and describe how scientists identify the relatedness of various organisms based on similarities in anatomical features. L.EV.M.1 Species Adaptation and Survival – Species with certain traits are more likely than others to survive and have offspring in particular environments. When an environment changes, the advantage or disadvantage of the species’ characteristics can change. Extinction of a species occurs when the environment changes and the characteristics of a species are insufficient to allow survival. Why do animals have different adaptations and survival skills? L.EV.05.11 Explain how behavioral characteristics (adaptation, instinct, learning, habit) of animals help them to survive in their environment. What physical characteristics of organisms help them survive in their environment? L.EV.05.12 Describe the physical characteristics (traits) of organisms that help them survive in their environment. Fifth Grade Science Pacing Guide – Revised April 2010 What behavioral characteristics of animals help them survive in their environment?

Essential Questions What evidence to fossils provide? How have natural occurrences affected animal’s lives? How can catastrophic events be linked to specific changes in environmental conditions? L.EV.M.2 Relationships Among Organisms – Similarities among organisms are found in anatomical features, which can be used to infer the degree of relatedness among organisms. In classifying organisms, biologists Why is it important consider details of internal and external structures to be more important than behavior to classify organisms? or general appearance. L.EV.05.21 Relate degree of similarity in anatomical features to the classification of contemporary organisms. What degree of similarities in anatomical features helps classify contemporary organisms? Assessment Students design an imaginary organism with specific behavioral and physical characteristics allowing it to survive in a chosen environment. A written description of the characteristics must be included in the diagram or illustration. Students analyze fossil evidence to determine how environmental conditions changed over time. In pairs, students place a variety of vertebrates into groups based on similar characteristics. They should be able to give a title to each group and defend their choice.

Understand that characteristics of mature plants and animals may be inherited or acquired and that only inherited traits are passed on to their young. Understand that inherited traits can be influenced by changes in the environment and by genetics. How does the environment and genetics affect inherited traits? L.HE.M.1 Inherited and Acquired Traits – The characteristics of organisms are influenced by heredity and environment. For some characteristics, inheritance is more important; for other characteristics, interactions with the environment are more important. What is the difference between inherited and acquired traits? L.HE.05.11 Explain that the traits of an individual are influenced by both the environment and the genetics of the individual. L.HE.05.12 Distinguish between inherited and acquired traits.
