Physical Science Unit 5: Matter, Forces, and Motion

1. Physical ScienceUnit 5: Matter, Forces, and Motion Unit Portfolio Presentation Felix Norman V. Macainan III Fair Park High School

2. Unit Summary STUDENTS CAN: • Develop the basic understanding of how matter, motion, and forces are related, along with a comprehension of Newton’s laws of motion and the effects of forces on objects. • Design experiments to accurately test hypotheses about motion, speed, and direction. Explore thoroughly Newton’s laws of motion. • Develop the ability to construct and interpret graphs of motion building on Newton’s second law. Explore conservation of momentum in collisions.

3. Curriculum Framing Questions Essential Question: • How and why do things move? Unit Questions: • When is an object in motion? • How can we know if an object is accelerating? • How can you describe motion as constant, and determine speed, acceleration, and velocity? • How do you use Newton’s laws of motion to analyze and describe how things move?

4. Curriculum Framing Questions Content Questions • What is speed? • What is velocity? • How do the position, direction, and time help us determine the speed or velocity of an object? • How can you graph motion? • What does the slope (rise/run) of a graph “Distance vs. Time” tell us about the speed? Why? • What is acceleration?

5. WACKY RACE CAR PROJECT BENEFITS: This Project Based Learning will develop my students the 21st century learning skills which include: • Communication (oral and written) and presentation skills • Organization and time management skills • Research and inquiry skills (promote higher order thinking skills) • Self-assessment and reflection skills • Group participation and leadership skills.

6. Gauging Student Needs Assessment The Essential and Unit Questions will help my students understand Physics concepts in a series of investigative experiments such as: • Science inquiry and scientific evidence • Identification of various experiment variables • Speed, acceleration and Newton’s Laws • Plotting of Graphs for position, speed and time • Using a Scientific Model to predict variables, viz. speed. • Develop analytical and higher-order thinking skills

7. Gauging Student Needs Assessment What will I learn from the assessment? • Different levels of knowledge and understanding among students (differentiated instruction) • Craftsmanship, adeptness or proficiency (artistic talent, creativity and dexterity) • Scientific communication and analytical skills

8. My Goals for the Course • Find motivation and techniques to make Science appealing to students. • Apply arts and craftsmanship to various scientific investigation and experiments • Instructional technology • Time management and organizational skills • Collaborative learning among students • Constructive feedback from peers in school • Experiential learning and higher-order thinking

9. WACKY RACE CAR PROJECT What is the Wacky Race Car Project? Construct a similar car that can fit specifications of the ramp of the CPO Motion/Acceleration Kit. Car and Ramp Kit Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

10. WACKY RACE CAR PROJECT What kind of materials do I need? • A pinewood car kit and body builder kit for modifications and enhancement of the car. • Or any other material that can make the race car faster and reliable on the ramp.

12. Sample Investigation Using CPO Science Kits: • What kind of motion happens when an object rolls down a hill? Position, Speed and Time Graphs Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

13. Sample Investigation Using CPO Science Kits: The position vs. time graph • Position vs. time data tells you the runner’s position at different points in time. • The runner is at 50 meters after 10 sec., 100 meters after 20 sec. and 150 meters at 30 sec. Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

14. Sample Investigation Using CPO Science Kits: Graphs show relationships • A good way to show a relationship between two variables is to use a graph. • A graph makes it easy to see if changes in one variable cause changes in the other variable (the effect). Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

15. Sample Investigation Using CPO Science Kits: The position vs. time graph • Two variables may have: • a strong relationship, • a weakrelationship, • or no relationship at all. Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

16. Sample Investigation Using CPO Science Kits: Graphs show relationships • This table shows how quickly the car gets from A to B as the angle of the track changes. Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

17. Sample Investigation Using CPO Science Kits: Newton’s Second Law • What happens when force is applied to something that can move? Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

18. Sample Investigation Using CPO Science Kits: Newton’s Second Law • The second law is the connection between force, mass, and motion. Reference: http://www.cpo.com/home/ForEducators/FoundationsofPhysicalScience3rdEdition/tabid/270/Default.aspx

19. Sample Investigation Using CPO Science Kits: Acceleration and mass • Acceleration is inversely proportional to mass. • When the forces stay the same, increasing mass decreases the acceleration.
