What type of system is the Digestive System?
natural system
What is iterative testing?
Design testing that is repeated many times.
What is the initial step in the engineering design process?
The first step is to define the problem.
What are the two types of systems?
natural systems and engineered systems
A system made by men.

Every morning, Ms. Ana looks at the birds eating from the birdfeeder outside her window. After a storm, she realized the birdfeeder collapsed, so she decided to create one.
Before installing it outside, she used recycled materials like cardboard, plastic bottles, and popsicle sticks to construct a small-scale model of the bird feeder, testing its stability and functionality.
Reread the paragraph that is underlined. What step of the engineering design process is it showing?
Step 5: Create a prototype.
Cost, time, resource availability, laws, and scientific understanding are examples of ________________.
constraints
What is the difference between a prototype and a final product?
A prototype is an early version or model of a product, while a final product is the completed and refined version.
What are the two parts or components of a system?
the input and the output
The limits of a system.

The Solar Panel System is a type of _________________ system.
engineered system
What is the criteria of a solution?
The features or qualities the solution should have.
What is step #6 of the engineering design process?
Testing and evaluating.
What is the input of a system?
Matter, energy, or information that enters a system.
Another way to say "parts".

Lucy decided to set up a Lemonade Stand outside her house. She makes her own lemon juice and sells it to her neighbors.
The Lemonade Stand is an example of a system. Name one input and one output.
Inputs: lemons, sugar and water.
Outputs: lemonade and money.
Giving up one design advantage in order to keep another is called a _____________.
tradeoff
How does the iterative testing step help engineers improve their designs?
It allows engineers to make multiple iterations or revisions to their design based on feedback and testing results to improve it and find the best solution.
What is a boundary?
The edges or limits of a system.
The third step of the engineering design process.

Joe’s backpack is very uncomfortable, it is also very small and has very limited space. He carries most of his things in his hands because they don’t fit. He has the idea of designing a better backpack that is comfortable to carry and has enough space for books and supplies.
To do this, he starts researching different types of materials and backpack designs to understand what makes a backpack comfortable and functional.
What step or steps of the engineering design process can you identify?
Step 1: defining the problem.
Step 2: identify criteria and constraints.
Step 3: Brainstorm multiple solutions.
