Seeding+Speeding

**Science 10 Problem Based Learning Curriculum Resource: Seeding Speeding**
The motion of an air seeder is described in this case as students prepare a seeding report based on planting patterns in a field of canola. Students will have to describe the seeders speed and acceleration from a planting map that is supplied. It will be necessary for groups to graphically represent distance vs. time for each of the four plantings, as well as distance vs. speed. Students will need to operationally define uniform and non-uniform motion. Students will analyze the graphs and identify the physical quantity that the slope of the distance-time graph represents as well as be able to identify the quantity that the slope of the speed-time graph represents and what the area under the speed-time graph represents. Students are then asked to provide an ideal speed for the seeder to be travelling in order to drop seeds at a given distance.
 * Case Focus:**

//How can we describe the speed and acceleration of the air-seeder based on the growth patterns of canola in such a way that the information is graphically represented and explained in a short seeding report?//
 * Sample problem statement:**

MW1: Explore motion related technologies MW2: Observe and describe the motion of everyday objects MW3: Investigate the relationship among distance, time, and speed for objects that undergo uniform motion MW4: Investigate the relationship among speed, time, and acceleration for objects that undergo uniformly accelerated motion MW5: Analyze graphically and mathematically the relationship among distance, speed, time, and acceleration for objects that undergo simple linear motion or uniformly accelerated motion
 * Objectives Met: **
 * Physical Science**: Motion in our world
