|Name of Activity||TinkerCad Name Tags|
|Keywords||Tinkercad, 3D, modeling, laser cutting, 3D printing|
|Time||4+ Hours Total|
|Brief Description||This lesson focuses on the basics of TinkerCad by teaching students how to create their own customized name tag that is later 3D printed or laser cut.It must be noted that this activity works best if there is internet readily available since TinkerCad runs on Google Chrome or Firefox. This activity would also work better in a computer lab where all students can work on their projects at once.|
|Lesson Objectives:||-Introduce students to 3D modeling
-Introduce students to printing software such as laser cutters and 3D printers
-Inspire students with projects done by others
-Introduce students to TinkerCad basics such as: grid settings, moving around, shape generators, text generators, holes, extrusion and sizing.
-WIFI or Ethernet connection is a must since Tinker Cad works on Google Chrome or Firefox
-Paper to design name tags before jumping into software.
|Preparation and Set Up:||-Gather enough computers, and chargers
-Get mouses if possible. Makes clicking around much easier.
-Have students draw out name tag design on paper
-Log into Tinker Cad account (worked best if one account was used to save all student’s designs).
|Knowledge Background||3D printing and laser cutting applications in today’s world. Drawing and shape generating. 3D modeling is like art.|
|Procedure||1. Design model on paper: including shapes, sizes (3 in X 3 in worked nicely), cartoons, name, and holes (for strap).
2. Prepare a new model on Tinker Cad:
3. Create base: Have students browse through the shape generator to see what shape they want their name tag to be. Have them make that their base so that all other extrusions, text, and holes are placed onto the base.
4. Choose location of holes: This was generally done by choosing the cylinder shape and making it a hole instead of solid. Check to make sure it goes through the name tag. Any other shape can be used.
5. Teach text editor to apply name: The Text editor option is a nice easy way to write text! Different fonts can be used, and the whole text is treated as one object that can be re sized and even turned into a hole for engraving. If Text editor is undesirable, Tinkercad has individual letters as objects that can be placed, re-sized, and turned into holes.
6. Apply images from online, or search for .stl files on Thingiverse for more customization: Due to a lack of time many of the name tags had objects imported from other websites like Thingiverse. .STL files can be imported into Tinkercad using the import section, and the files can be easily manipulated.
7. Differentiate between engraving and creating hole extrusions: Make sure students can tell the difference between making objects that cut completely through, or objects that engrave into the base of the name tag. This means checking the thickness of each object and making sure it fits what is desired. Keep in mind that some letters wont come out how they look when printed. For Example: if the letter D is desired to be completely cut through the entire name tag base there wont be any filling inside of the D. It will just fall out when it is laser cut.
After All models are complete: 3D Printing: All designs on Tinker Cad can be exported as .stl files. Other options are also available. Each option depends on your printer’s needs. Laser Cutting: There is an option to download models as .SVG. However, for our laser cutter more work had to be done. How we did it:
Keep in mind each printer and cutter is different. The settings depend on the printer and material! There is also an option to take screen shots of a top view of each model and using that in illustrator instead of going through all the Solid Works trouble. However, the angle of the shot may mess things up. *Cut away!
|Extensions:||This activity would work better in a computer lab. We spent too much time splitting up the class to allow everyone to use tinker cad on the STOMP computers. This made our lessons hard to plan since half of the class was working on different things.|
|Modifications:||More has to be done in terms of having proper ways to cut and how to transfer models.|

|Name of Activity||Three Little Pigs IEL|
|Author||Matthew Mueller and Sarah Copolla|
|Keywords||integrating engineering and literacy three little pigs client based design|
|Grade Level||4, 5|
|Time||3 Hours Total, 4+ Hours Total|
|Brief Description||The story of the three little pigs was introduced and the problems of pig 1, pig 2, and the wolf were posed to the children. The two pigs needed stronger houses, but still wanted their houses to look like straw and sticks respectively (it was the trade of their family), and the wolf needed help knocking down the brick house but the design needed to be portable so he can carry it with him.|
|Lesson Objectives:||Looking at the characters in the story as clients that are being designed for. They have problems that need to be solved, but each client has certain constraints that need to be considered.|
|Materials Needed:||Straw, sticks, any found or reasonable material that the kids propose and can use to build their design.|
|Necessary Background||Know the three little pig story.|
|Procedure||Tell a brief version of the story or have the kids tell it. Point out each potential client, their problems, and what the constraints of the solution might have. Each kids will then brainstorm, design, and request materials they can use to prototype their design.|
|Extensions:||They can test and redesign their ideas if they have time.|
