Design Step 1: Identify the Need
Read the Fine Print
Educational Use
Rating

Students practice the initial steps involved in an engineering design challenge. They begin by reviewing the steps of the engineering design loop and discussing the client need for the project. Next, they identify a relevant context, define the problem within their design teams, and examine the project's requirements and constraints. (Note: Conduct this activity in the context of a design project that students are working on, which could be a challenge determined by the teacher, brainstormed with the class, or the example project challenge provided [to design a prosthetic arm that can perform a mechanical function].)

The website physics.gpclements.com has annotated lists of YouTube videos for both semesters of introductory physics. The lecture videos follow the order in the OpenStax Physics textbook. The level is suitable for high school and college students. There is a short (15 minutes or so) lecture for each topic and example problems that are worked out step by step. The site also lists a few calculus level physics videos. There is no charge for viewing the YouTube videos.

Lab Research to Engineer a Phosphorescent Bioplastic
Read the Fine Print
Educational Use
Rating

Students gain first-hand experience with the steps of the scientific method as well as the overarching engineering design process as they conduct lab research with the aim to create a bioplastic with certain properties. Students learn about the light mechanism that causes ultraviolet bead color change, observe the effect of different light waves on a phosphorescence powder, and see the connection between florescence, phosphorescence and wavelength. Students compose hypotheses and determine experimental procedure details, as teams engineer variations on a bioplastic solid embedded with phosphorescence powder. The objective is to make a structurally sound bioplastic without reducing its glowing properties from the powder embedded within its matrix. Groups conduct qualitative and quantitative analyses of their engineered plastics, then recap and communicate their experiment conclusions in the form of a poster, slides and verbal presentation. As an extension, teams make their own testing apparatuses. As a further extension, they combine all the group results to determine which bioplastic matrix best achieves the desired properties and then “manufacture” the optimum bioplastic into glowing toy figurine end products! Many handouts, instructions, photos and rubrics are provided.

Challenging math problems worth solving.

The name “Open Middle” might sound like a strange name for a website about math problems. However, it references a very specific type of problem we try to encourage here. Most of the problems on this site have:
* a “closed beginning” meaning that they all start with the same initial problem.
* a “closed end” meaning that they all end with the same answer.
* an “open middle” meaning that there are multiple ways to approach and ultimately solve the problem.

Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding. They support the Common Core State Standards and provide students with opportunities for discussing their thinking.

The purpose of Preservation Problem Solvers is to encourage students to use leadership and resourceful behaviors to think like a scientist. This module extends the Essential Strategies of Attributes, Questioning, and Creative Problem Solving introduced in Kindergarten and First Grade, is for all students. The classroom teacher should work with a specialist or special educator to find or develop alternate activities or resources for visually impaired students, where appropriate.
