<p>Lesson Plans and lab work is now available on my teacher pay teacher site, <a href="https://www.teacherspayteachers.com/Product/3D-Printable-DNA-RNA-Manipulative-Lab-1-3452084">https://www.teacherspayteachers.com/Product/3D-Printable-DNA-RNA-Manipulative-Lab-1-3452084</a></p> <p>This is a dual extrusion remix of my popular DNA/RNA manipulative set.<br/> When I tested this in class, there was some problems seeing the letters in the tiles if the class lighting was off. If you have students with visual impairments, you can print these in bold contrasting colors. Future versions can have braille on the pieces.</p> <p>This is a remix of <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a></p> <p>This is designed to model DNA, RNA, DNA / RNA coding, as well as all other process of DNA / RNA transcription.</p> <p>I am also working on a CRISPER / Cas9 restriction enzyme expansion set so you can explore how this new gene editing technology works.</p> <p>Printing instructions: The base tiles are marked as ptA, while the letter inlays are ptB. I used the dual extrusion settings of Cura to print them together.</p> <p>You can use this with the restriction enzyme set or amino acid set to learn how to transcribe DNA to RNA to protein.</p> <p>I am also working on a CRISPER expansion set.</p> <h3>Print instructions</h3><p>Unassociated tags: #MakerEdChallenge2</p> <h3>Category: Biology Print Settings</h3> <p><strong>Printer Brand:</strong> LulzBot</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2nxubRO">TAZ 5</a></p> <p><strong>Rafts:</strong> Doesn't Matter</p> <p><strong>Supports:</strong> Doesn't Matter</p> <p><strong>Resolution:</strong> .3 - .1</p> <p><strong>Infill:</strong> 5%</p> <p><strong>Notes:</strong></p> <p>Printed on a dual extruder, Print with a ooze shield and tower.</p> <h3> Post-Printing</h3> <p><strong>Post-printing</strong></p> <p>Remove the ooze shield and sand off any rough edges. These should lie flat to stack easily.</p> <h3> How I Designed This</h3> <p><strong>How I Designed this</strong></p> <p>This is a remix of my original DNA / RNA manipulative set that I made in TinkerCAD. I will post a video about how to set up the files for dual extrusion.</p> <h3> Custom Section</h3> <p><strong>Project Dual DNA / RNA</strong></p> <p>Use the instructions from <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a> to write your lesson plan. This dual colored set of tiles provide a vibrant splash of color for this set. You can use this to test and explore dual 3D printing in class.</p> <p>If you have students with visual impairments, or the lighting in your room is sub-standard,these high viability tiles can help you in class.</p> <p><strong>Overview &amp; Background</strong></p> <p>For this project you can do the following.</p> <ol> <li>Explore how to 3D model a dual extrusion print.</li> <li>Use this file as a set for dual extrusion 3D printing. </li> <li><p>Use this set to explore DNA / RNA.<br/> All other overviews can be seen in the remix <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a></p> <p>Beforehand you should review the basic of inheritance, Mendelian genetics, and heredity.</p> </li> </ol> <p><strong>Audience</strong></p> <p>This is intended for Middle School to College level biology classes. This works great for home school students.</p> <p><strong>Subjects</strong></p> <p>Middle School, High School, AP, and college level biology.</p> <p>Possibly include coding in computer programing.</p> <p><strong>Standards</strong></p> <p>See <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a> for standards.</p> <p><strong>Lesson / Activity</strong></p> <p>See <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a> for activity and lessons.</p> <p><strong>Duration</strong></p> <p>This can take 2 weeks to a month or more depending on the depth of your lesson plan.</p> <p><strong>Preperation</strong></p> <p>See <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a> for teacher prep.</p> <p>You will need a dual extrusion 3Dprinter to print this set of tiles. I used a Luzbot Taz 5 with a dual extruder.</p> <p><strong>References</strong></p> <p>The tiles came from a paper design in a popular Middle School science textbook. You can use your text to model how DNA and RNA is replicated.</p> <p><strong>Assesment</strong></p> <p>See <a href="https://www.thingiverse.com/thing:1259352">http://www.thingiverse.com/thing:1259352</a> for assessment.</p> <p><strong>Handouts</strong></p> <p>Lesson Plans and Handouts will be posted for sale on my teacher Pay Teacher webpage.</p>
