3D design and print for math and science concepts
The goal of 3D printers in the classroom should be to apply classroom concepts. In this issue we dive into the creation of a product. This product reinforces math skills in geometry. The finished product allows students to apply basic science concepts. These concepts include mass, velocity, and acceleration.
Projects are often left out of the regular classroom routine and lesson plans. Projects are long and complex. There isn’t always time to complete a project. This doesn’t mean we shouldn’t attempt to work on projects. At the end of the issue I include a lesson breakdown.
Students will develop a car using TinkerCAD. Students will learn a variety of skills. They will use TinkerCAD to form new shapes. Shapes are formed when two or more geometric shapes are combined. New shapes are also formed when one shape is used to remove material from another. The steps in the development of this car are intricate. I have tried to simplify them whenever possible. To simplify steps I have taken alternate paths to explain steps. The aim is to make the process easy to follow for the inexperienced Tinkercad user.
Many of the steps are repeated in the lessons. This is by design. Practicing skills helps to develop a memory for using those skills. Some steps are repeated in different contexts.
Designing the Car
Students will use traditional methods to design the car. They will use paper, pencil, and a template. The template is available for teachers to print and share with students. The template is based on the model developed in these lessons. A link to the template is available on this blog post.
Use the model to reinforce math and science concepts. Review mass, motion, and acceleration. Review the concept of velocity and how it differs from acceleration.
The development of the model uses a variety of shapes. These shapes include cylinders, cubes, and rectangular prisms. Take the time to review basic concepts related to these shapes. Some of these concepts include radius, diameter, area, and volume.
