Submarine Powered By Rubber Bands

thingiverse

This model of a submarine is built with simply four geometric shapes components in Tinkercad. A Square, Sphere, Paraboloid and Tube. Print this model to enjoy, or get inspired to create Snappy Science. Stretched rubber bands are loaded with potential energy! I have include a step by step walk through instruction on how to create this model. Great for Students Learning about Science and How Potential Energy works!http://youtu.be/tgxj8o0k_x0 Print Settings Printer: Malyan M180 Supports: Yes Resolution: 0.2mm Infill: 20% How I Designed This In this section we’ll talk about how designed our 3D model of a Submarine. In the next sections you will learn how to preform drag and drop the geometric on your workspace. How to change the dimensions. How to hollow out the geometric shapes. You will also learn how to align and group the shapes together. Tools: Needle Nose Plyers Material: Jumbo-smooth paperclip, rubber bands. To scale each shape to the exact size we use the Ruler tool from the Helper menu on the right side To scale each shape to the exact size we use the Ruler tool from the Helper menu on the right side To hollow out the shape use the Holes tool from the Helper menu on the right side. To align the shape click on the Adjust menu at the top menu bar. To group the shape together click on Group menu at the top menu bar Project: Design a Submarine that is powered by potential energy from Simple Components. A Square, Sphere, Paraboloid and Tube. Print this model to enjoy, or get inspired to create Snappy Science. Stretched rubber bands are loaded with potential energy! I have include a step by step walk through instruction on how to create this model. Great for Students Learning about Science and How Potential Energy works! Objectives • Design and create 3D printed submarine from scratch. • Build complex designs from simple component pieces. • Learn basic 3D design skills and how to use Tinkercad or other modeling software. • Explore science with the use of potential energy Audience • Anyone of any age that is new to 3D modeling can use this modeling project to get started with Tinkercad • Students in grades that are learning about science of energy. To study how energy is stored and release. • Learning how to construct model that use potential energy Preparation • Students will need access to computers and a reliable internet connection, and be logged into a free Tinkercad account (either with their own accounts, or each logged into the same classroom account). • Tinkercad is easier to use with a mouse than with a tablet or trackpad, so computer mice are recommended. • No previous 3D design experience is required for the students, although familiarity with Tinkercad would be helpful. • The instructor should be comfortable answering modeling questions about Tinkercad and be able to advise students to avoid design features that might cause printing difficulties (overhangs, delicate features, etc). • It is helpful to have students form into working groups of two or three so that they can collaborate on the design process. Having students work in groups is also helpful if you have a limited number of computers and/or limited 3D printer access Classroom Steps & Other Thought Experiments Step 1: Have each group of students choose a specific part of the submarine to create. Step 2: Have students prepare for creating 3D model of sub part to print. Step 3: Have the students shape the paperclip and assemble the model together. Step 4: To test how many windings of the rubber band to propel the submarine set a distance to reach. To study how many rubber bands to use. Step 5: Alternative test is to test buoyancy. Have the students add holes in the model and to add weight to the bottom of the model to get is to propel underneath water. Step 6: How much more potential energy to move the submarine while underwater Put your wonderful imagination to work!
