# IF I SAY “APPLE” APPEAR; IF I SAY “PEAR” DISAPPEAR: STEM HOUSE

Imagine a house that grows when we want it and shrinks when we don’t! What is ergonomics? Is it possible to design an ergonomic house? With STEM yes!

Student age:13-14

Subjects: math, engineering, technology

Objectives:

• Calculates the area of ​​a rectangle, using square centimeters and square metres.
• Solves problems that require calculating the area of ​​a rectangle.
• Explain the importance of ergonomics in product design.
• Express that functional differences lead to structural differences in architectural design.
• Express the relationship between engineering and design.
• Designs an ergonomic house using the engineering design process.
• Makes sketches for design.
• Converts draft drawings into three-dimensional visuals with the help of computer.
• Creates the model or prototype of the design.

Materials that can be used: Computer, scissors, cardboard, Pvc foam board, plexiglass, clay, ruler, pencil, glue, etc.

Abstract: First of all, I explained the subject of field in mathematics to the students. Then I focused on the concept of ergonomics and showed examples from daily life. I started with the subject of architectural structures. We brainstormed and discussed ergonomics in architectural structures. Based on the information we obtained, I asked the following question: “If you were an engineer, what kind of ergonomic house would you design?” Students designed an ergonomic house using the Tinkercad web 2.0 tool. Later, they made a model or model of the house they designed with materials such as Pvc foam board, cardboard, plexiglass, clay, etc.

While implementing the house model, the students made use of waste materials as much as possible. They drew attention to small details such as doors, windows, fences in the garden, swings, etc. When designing small details, for example, they used 3D printing on flowers in the garden. They took care to design collapsible systems. They designed a portable balcony, terrace, roof, etc. Here are some examples;
