Title:
Newton's Laws of Motion
Overview/Annotation:
Students use toy cars, a CBR sonic motion detector, and pennies to investigate Newton's Laws of Motion.
Associated Standards and Objectives
Content Standard(s):
SC (8) 8. Identify Newton's three laws of motion.
Defining terminology such as action and reaction forces, inertia, acceleration, momentum, and friction
Interpreting distancetime graphs TC2 (68) 11. Use digital tools and strategies to locate, collect, organize, evaluate, and synthesize
information.
Examples: locating—Boolean searches, graphic organizers, spreadsheets, databases
collecting—probeware, graphing calculators
organizing—graphic organizers, spreadsheets
evaluating—reviewing publication dates, determining credibility
synthesizing—word processing software, conceptmapping software
TC2 (68) 13. Use digital tools to formulate solutions to authentic problems.
Examples: electronic graphing tools, probes, spreadsheets
SC2015 (8) Physical Science 9. Use Newton's second law to demonstrate and explain how changes in an object's motion depend on the sum of the external forces on the object and the mass of the object (e.g., billiard balls moving when hit with a cue stick).
SC2015 (8) Physical Science 10. Use Newton's third law to design a model to demonstrate and explain the
resulting motion of two colliding objects (e.g., two cars bumping into each
other, a hammer hitting a nail).*
Local/National Standards:
Primary Learning Objective(s):
Students will analyze the effects of force, mass, and acceleration. Students will follow written lab procedures.
Additional Learning Objective(s):
Students will use technology in a science setting to gather, record and analyze data.
Preparation Information
Total Duration:
31 to 60 Minutes
Materials and Resources:
Per group of students: Ramp, 2 equal mass Hot Wheels toy cars, 5 pennies, tape, meter stick, lab procedures (see attachments)
Technology Resources Needed:
CBR sonic motion detector, graphing calculator
Background/Preparation:
Students and teacher need to know how to use the CBR and graphing calculator.
Procedures/Activities:
1.)The lesson is divided into 3 labs that can be completed in any order. In lab 1 (see attachment), the students explore Newton's 2nd law of motion.
2.)The lesson is divided into 3 labs that can be completed in any order. In lab 2 (see attachment), the students explore Newton's 3rd Law of Motion.
3.)The lesson is divided into 3 labs that can be completed in any order. In lab 3 (see attachment), students explore Newton's 3rd Law of Motion.
4.)After labs have been completed, facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton's Laws of Motion.

Assessment
Assessment Strategies
The teacher will check the entries in the lab book for completeness and accuracy.
Acceleration:
Students may want to find the force of the crashes using the formula F=MA. Students will need to find the mass of the cars and the pennies. Some students may also find it interesting to find the speed of the cars. For more advanced students, a scale speed can be obtained.
Intervention:
Some students may need extra preparation with the Laws of Motion. Teachers may want to restate the laws in simpler terms.
