STEM Test Flashcards
Engineering and Design Process step 1.
- Identify the Problem:** Clearly define the problem or challenge.
Engineering and Design Process step 2:
- Research:** Gather information and data related to the problem.
Engineering and Design Process step 3
- Brainstorming:** Generate creative ideas and potential solutions.
Engineering and Design Process step 4
- Design:** Develop detailed plans, sketches, or prototypes.
Engineering and Design Process step 5
- Build or Prototype:** Construct a physical model or prototype.
Engineering and Design Process step 6
- Test and Evaluate:** Assess the performance and functionality.
Engineering and Design Process step 7
- Iterate:** Make improvements based on testing results.
Engineering and Design Process step 8
- Communicate:** Present the final design and findings to others.
Criteria:
Measurable standards used to evaluate the success of a design.
Constraints:
Limitations or restrictions affecting the design process (e.g., budget, time, resources).
Causes of Earthquakes:
Tectonic Plate Movements: The shifting of Earth’s plates is a primary cause.
Volcanic Activity: Eruptions can induce seismic events.
Human Activities: Some earthquakes result from human actions like mining.
Seismic Wave
Seismic waves are caused by the sudden movement of materials within the Earth.
P wave
Primary waves are the first to appear and can travel through solids, gases, and liquids.
S wave
Secondary waves that only travel through solids.
Tremor
A small earthquake in which the ground shakes slightly.
Richter Scale:
- A logarithmic scale measuring the magnitude (energy release) of earthquakes.
- Each whole number increase signifies a tenfold increase in amplitude and energy release.
Tension:
Force pulling materials in opposite directions.
Compression:
Force pushing materials together.
How do 3D Printers Work?
Layer-by-Layer Printing: Additive manufacturing by building objects layer by layer.
Material Deposition: Materials like plastics, metals, or powders are deposited and solidified.
How are 3D Printers Used in Society?
Manufacturing: Prototyping and producing customized products.
Medical Field: Creating personalized implants and prosthetics.
Education: Visualizing complex concepts and creating models.
Architecture: Developing detailed scale models of buildings.
Art and Design: Bringing intricate designs to life.
