Lesson Plan : Newtonian Physics / Acceleration
Teacher Name: | Mr. Snead |
Grade: | Grade 9-10 |
Subject: | Science |
Topic: | How do you find the acceleration of a moving object using velocity and time as well as force and mass? |
Content: | Calculating acceleration using two different formulas. 1st. acceleration = change in speed divided by the time. 2nd acceleration = force divided by the mass. Key Vocabulary Words are: force, Newton's first law, inertia, newton, net force, acceleration, deceleration, Newton's second law. |
Goals: | Student should know the difference between Newton's first law and second law. Student should know how to calculate the veloscity of an object by distance divided by the time. Student should know how to calculate acceleration by using velocity and time. Student should know how to calculate acceleration by using force and mass. Student should know how to convert distances from the metric system to the English system. Student should know how to use apparatus (car, track, timer, and photogate) to calculate acceleration problems. Student should know how to create a graph from a data table and interpret the results. |
Objectives: | Student will be able to calculate acceleration using force and mass. Student will be able to calculate acceleration using veloscity and time. Student will be able to set up apparatus to conduct experiments on acceleration. Student will be able to convert kilometers to miles and vice versa. Student will be able to convert meters per hour to meters per second. Student will be able to graph data gathered during the experiment. Student will be able to create a data table. Student will be able to analyze and interpret data. Student will be able to calculate the net force on an object. Students will be able to use the acceleration formula to solve for time or final velocity. Student will be able to use the acceleration formula to solve for force and mass. |
Materials: | SMART Board Technology, Laptop, CPO apparatus (timer, photogate, track, cars, weights), scientist notebook, graphing paper. |
Introduction: | Students will start the unit by reading the text in class along with the students. The text will be put on the SMART Board so that it can be dissected using the SQ3R strategy. Students will break down material into three categories (survey, question, read, recall, review). |
Development: | Students will work out problems on the SMART Board in front of the class with the help of the teacher to show and learn now to do problems. The problems will come from the math skill builder CD. Students will work in their assigned groups to complete laboratory experiments utilizing the first and second laws of physics and the formulas that pertain to those laws. |
Practice: | Students will try to do problems on the SMART Board with help form the instructor. The instructor will go over areas of difficulty with the students asking them to not only write the answer to the problem but to write out how they arrived at that answer so that I may see where their difficiencies lie. Student will look at laboratory problems and make flow chart about how they will conduct the experiment on poster board to help them visualize what they will be doing the day before they so an experiment. |
Accommodations: | I will give students calculators to use to help them solve math problems. I will use SQ3R to help those students who have trouble reading an getting out the core information. I will also have the students make index cards with the questions they create from SQ3R on one side and the answer on the other. They will use them as flash cards to help them retain the information in the reading. |
Checking For Understanding: | They will have to do a hands on laboratory experiment that will entail that they use the proper formula to solve the problem given. They will be given a quiz on whether they understand the math formulas solving for various situations via. (final velocity, acceleration, mass, force, and time). They will be given an examination where they will be asked to answer vocabulary related questions and solve math equations for the Newton's first and second laws. |
Closure: | The goal of student assessment is not merely to measure student performance but to improve it. |
Evaluation: | This will be looked at afer each part of the lesson. |
Teacher Reflections: | This will be completed at the end of the project |
