Unit: Motion and Forces
Grade Level: 6th
Estimated time requirement: 1--50 minute class period.

Summary: This lesson introduces the concepts of force, balanced forces,net force, and how friction can affect them.
Students will learn to identify when a force is being used, whether or not it is a balanced force.
Students will be assigned the task of finding examples of forces around the school. They will document them using the Nikon video camera then prepare a class powerpoint presentation.

Objectives: 1. Identify a force.
2. Identify when a force is balanced and when it is unbalanced.
3. Explain friction.

TEKS: 6.1 The student conducts field and laboratory investigations using safe practices.
6.1A Demonstrate safe practices during lab investigations.
6.2The student uses scientific inquiry methods during lab investigations.
6.2A Plan and implement procedures including asking quiestions, formulating testable hypotheses, and using equipment and technology.
6.2B Collect data by observing and measuring.
6.2C Analyze and interpret information to construct reasonable exploanations from direct and indirect evidence.
6.2D The student will communicate valid conclusions.
6.2E Construct graphs and tables using tools to organize, examine and evaluate data.
6.3 The student uses critical thinking and scientific problem solving to make informed decisions.
6.3A Analyze, review, and critiqye scientific explanations, including hypotheses and theories, as to their strengths and weaknesses using scientific evidence and information.
6.4A Collect, analyze, and record informantion using tools including timing devices, calculators, and probes.
6.4B Identify pataterns in collected information using percent, average, range, and frequency.
6.6 The student knows that there is a relataionship between force and motion.
6.6A Identify and describe the changes in position, direction of motion, and speed of an object when acted upon by a force.
6.6B Demonstrate that changes in motion can be measured and graphically represented.

Assessment: Students will be able to answer teacher related questions about the reading, correctly filling in notes from the lesson, making correlations between information presented in the chapter and simulated scenarios of balanced and unbalanced forces.
