Students use toy cars, a CBR sonic motion detector, and pennies to investigate Newton's Laws of Motion.
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.
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
Students and teacher need to know how to use the CBR and graphing calculator.
The teacher will check the entries in the lab book for completeness and accuracy.
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.
Some students may need extra preparation with the Laws of Motion. Teachers may want to restate the laws in simpler terms.
Each area below is a direct link to general teaching strategies/classroom
for students with identified learning and/or behavior problems such as: reading
or math performance below grade level; test or classroom assignments/quizzes at
a failing level; failure to complete assignments independently; difficulty with
short-term memory, abstract concepts, staying on task, or following directions;
poor peer interaction or temper tantrums, and other learning or behavior problems.
