Standards: Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions. (Grades 6 - 8) [2013] 1. Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale. (Grade 7) [2010] Essential Question: How can we copy nature in the engineering design process. Bell Ringer: Go to Google Classroom and complete the bell ringer. Activity: When you were younger, did you ever build a fort out of pillows or tree branches or scrap cardboard? Can you think of an example from nature that may have resembled your fort? To which animal structure was it similar? (Possible answers: A bat's cave or a bird's nest) When engineers use examples from the natural world to influence their design, we call this biomimicry. This week you're going to design a human structure that is based on an example from the subphylum animal kingdom. Your group will chose a vertebrate class and research ways in which animals of that class find or build their own structures for shelter. Using the information you have gathered, you will design a human structure that incorporates some of the useful features of the animal shelter. Let's look at an example. Suppose you chose the vertebrate class Aves, which includes all birds. Your group would research how different types of birds build their nest and what some of the great features of the nest are. What do you think some of the advantages of a nest might be? (Possible answers: lightweight, strong, sheds moisture, protects from predators, made from readily available building supplies, etc.) Ok, now let's think of how we could build a human shelter that has some similarity to a bird's nest. Any ideas? In the 2008 Summer Olympics in Beijing, the architects and structural engineers who built the main stadium designed it to look like an enormous bird's nest. It will be fun to see where your imaginations take you with this project! You will be working in groups of 3-4 students. No more than 2 groups may have the same Class of animal and no groups may choose the same animal in said groups. I have posted a question in classroom and the first two team to pick a specific Class by answering that question may have the class and animal.
I have added an assignment to Google Classroom. It is a worksheet you will use to help you in your design process. This document will be due on Wednesday. You will have a reflection due Monday by midnight and the final build will be due Monday by the end of class. We will use the same product rubric you have been being graded on up to this point. Exit Ticket: Leave a question on the parking lot.
