MOMENTUM

How do different surfaces affect the momentum of marbles?


Part of my guided inquiry requires me to focus on one of the questions from the selection.  My interest was lies in investigating how momentum influences our daily lives.  The connection I can draw from is riding in a car or walking down a ramp.  The only items I need to conduct my experiment were one small marble, one large marble, timer, two meters sticks, and extension cord.  The surfaces I choose to use in this lab are carpet, vinyl flooring, and laminate counter top.  My observation reveals that the speed of the marble was greater when the mass of the marble was larger.  The investigation also demonstrates that marbles travel a greater distance and move faster on vinyl floor.  Naturally, friction is a factor when the surfaces are not smooth.  When using this inquiry-based learning experience in the classroom, students will gain a more in-depth awareness of momentum.  To extend this lesson for students, I can supply students with other round objects that roll.  This will grant students with further exploration opportunities.  I think it is important to allow students to determine what modifications they want to make to the investigation.  It provides them with responsibility of taking ownership of their education.
