  • 1. INSTRUCTIONAL FOCUS DOCUMENT Fourth Grade/Science UNIT: 03 TITLE: Forms of Energy SUGGESTED DURATION: 25 days State Resources: RATIONALE: This unit bundles students expectations in order to scaffold student learning about energy, energy’s ability to travel to travel through different objects, and the effects of forces on an object. In Grade 3 students will have the opportunity to explore different forms of energy in their everyday life (3.6A). In this unit, students will be differentiating between the different forms of energy, so that by Grade 5 they may to explore the many uses of energy in a meaningful way. It is important to note that this will be students’ first introduction to conductors and insulators. The focus will be on the idea that energy‘s ability to travel is affected by the object through which it travels. This will allow students as fifth graders to better understand how the ability of light to travel in a straight line can be altered by mediums through which it travels. Similarly, students will have no previous experience with electricity and how it travels. An understanding of how electrical energy travels will be a critical foundation for students prior to Grade 5, where they will be required to demonstrate how an electrical current can produce light, heat, and sound. Throughout this unit, students will also build a strong foundation on the critical skill of designing experiments to test the effect of force on an object. Student exposure to forces has been limited to magnetism and gravity (3.6 C). TEKS 4.6A is very similar to 5.8A from the 1998 TEKS; however, there is a marked difference in that the current standard has excluded the specific study of solar energy. Instead, it has been replaced with mechanical and sound energy. MISCONCEPTIONS/UNDERDEVELOPED CONCEPTS: MISCONCEPTIONS: • Students may think that energy can be made, used, and lost. • Students may think that force is the same as energy. • Students may think that gravity is the same as energy. • Students may think that energy from gravity depends only on the height of the fall. • Students may think that energy is an object or something that is tangible. • Students may think that objects use up energy instead of transforming energy. • Students may think that energy is used up. • Students may think that energy sources are the same as the energy. According to the Texas Administrative Code, school districts shall implement English Language Proficiency Standards (ELPS) as an integral part of each subject in the required curriculum. http://www.tea.state.tx.us/curriculum/biling/elps.html PERFORMANCE INDICATORS CONCEPTS KEY UNDERSTANDINGS FOR LEARNERS Choose one form of energy to represent. Prepare a Change – Energy Energy comes in many different forms and each form has debate to convince classmates that the form of energy unique characteristics which allow it to be distinguished represented is the most useful. Explain the advantages it from the others. has over all other forms of energy. (4.6A) ©2010, TESCCC 06/01/10 page 1 of 4

Write a brief paragraph that Systems – Energy inhibit energy transfer. explains which of the substances were used because they were determined to be insulators and which were not used because they were determined to be conductors. (May extend for writing, but can be brief to determine science content attainment) (4.2A; 4.6B) Design and build an electric circuit which will create an Systems – Energy Electricity travels in a closed path, which creates an electromagnetic field that will cause an iron nail to pick up electrical circuit. the largest number of paper clips. Explain the reasoning for the design. (4.2F; 4.6C) A simple electrical circuit can create an electromagnetic field. Draw a course that will employ pushing, pulling, gravity, Change – Force and Motion When a force is applied to an object, the object is affected. friction and magnetism forces to make a marble move the farthest. Describe how each of the forces helped to move the marble.
