Students will better understand the concept of friction as they apply it to a real world problem. Students will collaborate to prevent phones from getting broken while they are being shipped. To do this, students will need to design an investigation to see how they can increase the force of friction. Students will be tasked with developing a question to test, making a procedure, setting up their data table, collecting data, graphing the data and making conclusions. All of these steps are included in the student work packet. Students will share their results with the class in order to make evidence based conclusions.

Note: lab requires wooden blocks with hooks attached with different materials students can attach to the bottom (burlap, aluminum, plastic, cloth, etc.) materials that can be attached to a surface, and blocks of different sizes (small square, large square, small rectangle, large rectangle) so students are able to test different variables. (size/ shape, box material, floor material) A spring scale or other way (cup with string attached using washers) of measuring the amount of force is also needed.

NGSSMS-ETS1-3
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
NGSSMS-PS2-2
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. Emphasis is on balanced (Newton’s First Law) and unbalanced forces in a system, qualitative comparisons of forces, mass and changes in motion (Newton’s Second Law), frame of reference, and specification of units. Assessment is limited to forces and changes in motion in one-dimension in an inertial reference frame, and to change in one variable at a time. Assessment does not include the use of trigonometry.
