Vocabulary
Something that can be observed or studied.
Phenomenon
Tells the connection between the evidence and the claim. Answers the question, “Why does your evidence support your claim?”
Reasoning
Why is communication important in the engineering design process?
Scientists want to share their data with others, find mistakes others have made
What is the purpose of a microscope?
View microscopic organisms
How are models used in engineering designing?
Models are things that can be tested and analyzed.
Data collected during an investigation. Evidence answers the question, “How do you know that?”
Evidence
A real-world limit on the solution you are designing.
Constraint
What is the difference between scientists and engineers?
Scientists:
-Conduct investigations of natural phenomena
- Ask questions
- Discover
Engineers:
-Deal with solving problems and developing technology
Why do scientists use rulers?
Measure length and width of objects/organisms
True or False: Scientists perform a single observation or experiment and then come to a conclusion. They do not repeat the same experiment.
False
The desirable features of a solution.
Criteria
The process of giving up one quality or feature of a design to gain a different quality or feature.
Tradeoff
How do scientists use a computers to communicate with other scientists?
Use zoom (video chat) to speak face to face, email to communicate quickly, share data via email.
What would you use to measure volume of a liquid?
Beaker
What of the following questions would a scientist ask when studying a whale?
How do whales hold their breath for a deep dive in the ocean?
How does a whale find food in the dark parts of the ocean?
Why do whales shoot water from their blowholes?
How do whales communicate?
All of the above
An early version of a design to be tested.
Prototype
What is the first thing a scientist must do when conducting an investigation?
Ask questions
How people’s changing needs and wants have led to changes in technology?
People need more advanced computers for video chat, camera, microphones.
New phones for photos, texting, games, facetime, etc.
What would you use to see the weight of an object?
Balance scale
What are ALL Engineering Practices:
Asking Questions
Optimizing Solutions
Carrying out Investigations

Optimizing solutions and defining problems and solutions
A statement you think is true. Answers the question, “What do you know?”
Claim
What are the 3 steps of the scientific exploration?
Claim, Evidence, and Reasoning
How do scientists and engineers use models and prototypes differently?
Scientists:
- Use models to help carry out an investigation.
- Scientists use devices created by engineers.
Engineers:
Use models and prototypes to solve problems.
Engineers create devices.
What is the importance of science tools?
True or False: Scientists must be creative when designing experiments.
True
False
