Eighth Grade Science Standard: Use Newton's first law to demonstrate and explain that an object is either at rest or moves at a constant velocity unless acted upon by an external force (e.g., model car on a table remaining at rest until pushed). Write the standard in student-friendly terms. Break the standard down into measurable parts and present those parts in a sensible sequence. o Knowledge objectives (what the student should know) o Skill objectives (what the students should be able to do) Identify the prerequisite knowledge and skills students need before mastery of the identified standard can be obtained
