Make-A-Bot: Volume Project

thingiverse

The TYWLS Bot uploaded is the final product students will create in the make-a-bot volume project. The students will create a robot using parameters such as only using cones, cylinders, spheres, and prisms and a maximum volume. The students will next calculate the volume of the entire bot including converting to grams from inches and incorporating the 10% infill. Overview and Background Students will learn how to calculate the volume robot consisting of complex shapes using the formulas for a cone, cylinder, and sphere. Objectives By the end of the project/lesson, students will be able to: • Demonstrate how to calculate the volume of complex 3-dimensional shapes including cones, cylinders, and spheres. • Demonstrate their knowledge of CAD software through the 3-dimensional construction of robots on TinkerCAD. • Convert between cubic inches and grams. Audience 8th Grade or Pre-Algebra Mathematics Subject Math Volume Skills Learned (Standard) • 8.G.C Solve real-world and mathematical problems involving volume of cylinders, cones, and spheres Lesson Plan and Activity Students are completing this activity over the course of 4 – 5 class periods with a partner. Suggestions for planning time are below: • Before Class Prep: Have a printed model & corresponding model in TinkerCAD to show class and discuss expectations. • Day 1: Students brainstorm & design on worksheet I. • Day 2 - 3: Students create 3-dimensional model of design in TinkerCAD making improvements to original design. • Day 3 Homework: If not completed in class, students should be calculating the volume of the entire robot using worksheet II and will compare their work in next lesson. • Day 4: Review homework calculations and make any last adjustments to robot before submitting worksheet III to teacher for verification on Makerbot Desktop. *Ideally, worksheets can be uploaded on to google doc and shared with students so they can put screenshots directly into the worksheet and print to submit/work on. Extension Activity After students have completed project, printed bots can be taken to science class and the volume can be verified again when working with water displacement.
