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

Summary:In the previous lessons, students have been introduced to motion and ways to describe changing motion. The following lesson deals with the forces that cause motion to change.
Students will analyze motion using Newton's laws, calculate acceleration using force.

Objectives: 1. Using Newton's laws of motion, analyze different motions.
2. Calculate acceleration using force.

TEKS: 6.1 The student conducts field and laboratory investigations using safe and ethical practices.
6.1A Demonstrate safe practices during lab investigations.
6.2B Collect data by observing and measuring.
6.2C Analyze and interpret information to construct reasonable explanations from direct and indirect evidence.
6.2D Communicate valid conclusions.
6.2E Construct graphs and tables using tools including computers 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 critique scientific explanations, including hypotheses and theories, as to their strengths and weaknesses using scientific evidence and information.
6.3C Represent the natural world using models and identify their limitations.
6.3E Connect Grade 6 science concepts with the history of science and contributions of scientists.
6.4A Collect, analyze, and record information using tools including timing devices, calculators,computers, and computer probes.
6.4B Identify paatterns in collected information using percent, average, range, and frequency.
6.6 The student knows that there is a relationship 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 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 chapter reading, correctly filling in notes from the lesson, be able to correctly identify which law of motion is demonstrated, accurately produce and read the graphs, answer activity worksheet.
