CAD Design / Plastic Printing /Prototyping

Designing a cookie cutter appears to be quite simple, but students will get the chance to use offset, mirror and other commands if they are new to the sofware you are using. Adding structure to provide detail to the cookie will challange even the best students.

Students can do research to learn what makes an effective cookie shape. They can test their designs using cinnamon dough to create an ornament as long as they remember to puncture a hole in the top for hanging. Be sure you don't have anyone in the class with a gluten allergy. In that case, use a porcelain dough or air drying clay.



Use this activity for student to write reflections on their design. Despite the simple design, you will be pleasantly surprised at all that your students can write about the cookie cutter.


In a formal technically written document, discuss the following in 10+ paragraphs: 
I.  Scope of the project. (10) What did you need to design? (The project entailed . . . ) keep in active voice.
II.  Description of the solution with measurements, material, method of production. (15) Add Fig. # and Caption (My cookie cutter represented a  . . . )
III.  Discrepancies between the original design and the final constructed solution. (10) Add Fig. # and Caption
IV.  Successes and failures/setbacks encountered during all phases of the project. (10)
V.  What you learned from the failures/setbacks. (10)
VI.  Additional personal learning that occurred. (10)
VII.  Design flaws that exist in the system design and suggestions for improvements. (10)
VIII.  How this project helped you improve your:
I.   Problem solving skills. (5)
II. Communication skills through drawing. (5)
IX.  Conclusion (15)
I.     Summarize the information above.
II.    Reiterate the most important points of the project.
III.  Make a profound statement about steps of designing.


Rubrics can be quite tricky to get the points to settle out to the correct grading expectations. For the following rubric, you can get one whole grade or several if you wish. No matter what, get the average score of the categories you score and multiply by 10 and add 50 to convert the points to a score out of 100.

Chocolate Bar Design for Free Willy Wonka

Image
Every once in a while, I will see a new chocolate candy flavor or candy bar combination and think to myself, "Wow, that took them long enough to come up with that one or put that one out to the public." This year I want to challenge my students to design their own new charbolate bar combo like a Chunky or Snickers or even a new M&M flavor. For years I had my freshmen do marine themed chocolate bars. They design the shape and packaging. The 3.5 ounce chocolate limit forced the student to think about an individual bar design. Of course I would get starfish and anchors, but one year, I got one designed to be 1st Sgt. Nelson, one of our Naval Science instructors at the time because he was a marine! Situation The “Free Willy Wonka” chocolate manufacturer is looking for a new line of marine themed  solid or mixed ingredient   3.5 ounce chocolate bars to market along the coast (of a Spanish speaking country). Design Brief Design, develop and produce a 3.5-ounce s...

Lines & Shape to Create Formal Balance - Day of the Dead Masks

Image
Do you remember Shrinky Dinks? Apparently #6 plastic clamshell containers are the same material and react the same way! I'm thinking a toaster oven will work for this project or the stove in the main office teachers's room. Place on cookie sheet or parchment paper. Bake at 300 degrees until the plastic has shrunk and flattened out again. Each piece will require a different bake time depending on the size, but only takes a few minutes. Here's an activity that can be done using milk jugs, card stock or the clear plastic. Try doing this before November 1st. Sources: dia de los muertos skulls .

Line, Shape and Form Types

Image
Remember now, I teach at the beach. I know, how cool is that. I get to see the sun rise every day on the ocean. So what better subject matter to draw than objects related to the beach. When testing studends on the type of line, shape and form, some students would mix up which ones were mechanical and geometric. since I started teaching sophomores that all have chemistry, they now give me answers like organic and inorganic! Yikes! Practing the use of Line: Practincing the use of Shape: Practicing the use of Form:

Ideas for the Technology, Engineering and Design Studio or Lab

I love creating a new project. I love the moments of project inception and the excitement of the research and gathering my thoughts to formulate the actual projects. In fact, I have so many written up that I have never used, that I decided to launch this blog to share these ideas with others to use.  Whenever I attend a workshop or conference, I am satisfied with the event if I walk away with one new idea. I have come to realize that I am not alone. all of the attendees are seeking ideas to take back to to implement with their students. I often get bogged down by all of the project ideas I have and get frustrated with not being able to use them all.  Over the years, I have tried to give many of my ideas a marine theme becuase of the nature of the school that I have been at since Septmeber 1998. I certainly know where the time went, writing up new projects! So without further delay, I will start sharing the pages, assignments and projects that I have for you all to use a...

Identifying, Describing and Creating Texture

Image
These worksheets address Texture and force students to look around them for texture in their world. Texture is all around us and so often gets overlooked. often students will tell me that some objects have no texture, when in fact "smooth" is a texture and that is what they really should give as an answer.  Perhaps a list of texture words would be of some help to students new to identifying and describing surfaces. For instance, you would not say that a stone is stoney. Some students fall into the trap of naming the object rather than the texture. How would you describe etching on a glass bottle or mirror?  Textures: Bumpy, Smooth, Rough, Gritty, Slick, Silky, Soft, Prickly, Fuzzy, Hard, Woven, Rigid, Jagged, Chalky, Pasty, Bristly, etc. Some textures need further explanation like woven. A woven texture could be fine or coarse.  Some textures can be summed up using another word like the stiff and prickly hairs on a pig can be described as bristly. Depending on ...

New School Year Greetings

Image
I teach and am the sophomore class advisor. I thought I would greet the students this year with a treat. I found a bag of tootsie pops with enough for all 73 of my sophomores. So I whipped up these tiny capes on Word, cut them out and punched a hole in the circle part to go around the neck of the tootsie pop, and tied a ribbon around the neck to keep the cape on. I will either hand them out at the door or place on at each seat in my room. I actually fit two of these batches on a sheet of colored paper. After you cut them out and punch the holes, make a crease at the neck so the cap parallels the stick of the tootsie pop or whatever taffy you can find. If you can go to NJTEEA FB and post what you do for treats if anything. I use to put some gummi worms in a bag and make a label that said, "Early Bird Treats" and give a bag to the first person that walked in the classroom. Students would run to class after that!

Identifying and Creating Space

Image
I have found that students struggle with the concept of Space as they constantly want to put white space between their objects. So I often use the word depth instead. This worksheet helps them practice the different ways of creating space. Now, try to get your students to add shading detail to their work to make their images pop off of the page to provide depth or space.  Now try to get them to create some realistic looking objects using color, texture and space. Now get them to put their knowledge to work in a fun activity making a montague using various elements from other sources. See some examples of the previous worksheets and a montague here .

Negative and Positive Shape

Image
The Epilog Laser Cutter is a fascinating machine. This year I will be having my students create wooden trivet designs to cut out on the laser. I have 70ish students each year that all need an experience on the equipment. I think this will be a nice project with a take home item to share with the family. I plan to use 1/4" luan plywood for these laser cut items. I am anxious to see what the students design. This project can be used to reinforce any of the design principles, but students tend to forget what positive and negative space means, until I remind them about the cutouts in a pumpkin.

Grid Transfer and Detail

Image
In an effort to get students to pay attention to detail, I have them enlarge this turtle image to the given grid using only color pencils. I forbid them to use a regular pencil to transfer the imagery. Some students start in one corner and move across the image while others start with the turtle and continue out from the center. No way is the correct way as long as the image is transfered accurately to the grid. I allow the students to start the activity in class and then ask them to complete the image within a week. No need to drag out the process. I let them keep the colored pencils that they start with and return them when they are done. Turtle Source: Wintner , Anita. Green Sea Turtle. Retrieved on 9/5/16 from        http:// physiologizing.blogspot.com /2013/03/living-life-at-sea-diving-physiology- in.html The results are astounding and range from eh to wow! This lets the students see what others are capable of and if they need to pay more atten...
