Note that it should not be important if the device works perfectly or even that students find a successful solution. Sort the objects using two different devices.Sort the objects using a conveyor belt.In order to sort items, students will probably have to move away from the truck model and design another type of device:
Keep in mind that these tasks extend upon those of the previous section and are designed for older or more advanced students.Īsk students to design a third object to sort. Use the “Design further solutions” section of the student project as an optional extension. It is important to note that because a student model will vary according to student choice, there are no building instructions or sample programs provided to students for this part of the project.ĭesign further solutions (optional, 45-60 minutes) The boxes can be dropped at the factory and sorted in another way. This solution would require building something else in addition to or instead of the truck. Other designs may work just as well.īy placing the Motion Sensor on the side of the load in the proper position and by creating the right program, the sensor can detect objects based on size. There are simple and more complex solutions to this problem that may involve changes to the design of the sorter, the program, or a combination of both.īy removing the LEGO ® back plate of the truck, one box should be able to fall into the first hole while the other box slides off the back due to its shape. When a machine is used to sort objects, it needs to use one of the object’s physical characteristics, such as weight, size, shape, or even its magnetic properties, to process them.įrom this model, students should be able to change the design of the truck load to sort the boxes into two different groups according to their shape.People or machines can separate waste according to their kind and put all the paper, plastic, metal, and glass together.Materials typically must be sorted at the beginning of the recycling process, and many recyclable materials arrive at recycling centers all mixed together.People must adopt behaviour that discourages the throwing away of waste into the same place.Getting more people to consistently recycle their waste is a challenge, and one way to encourage more widespread recycling is to make sorting methods more efficient: Recycling can give a second life to the materials that you use. Recycling material is one of the 21st century’s biggest challenges. The introductory video may set the stage for the following ideas to be reviewed and discussed with students for this project.
