Engineering Design Process
What is another word for a limitation in the engineering design process?
A. Criteria
B. Constraint
B. Constraint
All living things are made of cells
True
What is the energy of motion?
A. Kinetic Energy
B. Potential Energy
A. Kinetic Energy
Rain, snow, and sleet are examples of:
A. condensation
B. evaporation
C. precipitation
C. precipitation
Adult humans have around 206 bones. How many bones do babies have at birth?
A. 220
B. 300
C. 350
Babies have about 300 bones at birth, with cartilage between many of them. This extra flexibility helps them pass through the birth canal and also allows for rapid growth. With age, many of the bones fuse, leaving 206 bones that make up an average adult skeleton.
Which step of the EDP is it important to first do independently?
A. Share
B. Collect data
C. Imagine / draw diagrams of your ideas
C. Imagine
Humans are made up of eukaryotic cells. Bacteria and Archaea are single-celled organisms made up of one prokaryotic cell.
Which cell type has a membrane-bound nucleus?
Eukaryotic cell
Does the potential energy of a ball increase or decrease as the ball is lifted higher above the ground?
increase
Another name for the dry side of a mountain is:
A. windward side
B. leeward side
C. desert side
B. leeward side
1. True of False: The Eiffel Tower grows and shrinks throughout the year.
2. Explain.
When a substance is heated up, its particles move more and it takes up a larger volume – this is known as thermal expansion. For this reason, large structures such as bridges are built with expansion joints which allow them some leeway to expand and contract without causing any damage.
What is the difference between an invention and an innovation?
An invention is the first design of its kind.
An innovation is an improvement on a design.
In a cell, which organelle contains all the DNA (the genetic material)?
A. mitochondria
B. chloroplasts
C. nucleus
C. nucleus
In the lab with the thermometers, spoons, and ice cubes what direction was thermal energy transfer occurring? (from what site to what site?)
Are clouds solids, liquids, or gases?
Liquids or solids. Gaseous water condenses on dust particles and can stay in a liquid form or, if high enough in the atmosphere, can be solid ice crystals.
A teaspoon of a neutron star weights:
A. 50,000 pounds
b. 6 billion tons
c. the weight of our Sun
B. 6 billion tons
A neutron star is the remnants of a massive star that has run out of fuel. The dying star explodes in a supernova while its core collapses in on itself due to gravity, forming a super-dense neutron star. Astronomers measure the mind-bogglingly large masses of stars or galaxies in solar masses, with one solar mass equal to the Sun’s mass. Typical neutron stars have a mass of up to three solar masses, with a diameter of only 12 miles across.
What is a prototype?
Why do people make prototypes?
A miniature version of a design.
Prototypes are cheaper and easier to build before building a full-sized design.
What are two differences between plant and animal cells?
plant cells have a cell wall; plant cells have chloroplasts; plant cell vacuoles are large and mainly contain water, whereas animal cells have smaller vacuoles that transport and discharge waste outside the cell
Which type of thermal energy transfer occurs only between fluids (it cannot occur with a solid).
Draw a diagram showing the rain shadow effect. Make sure to include a mountain range, an ocean, and label the wet side and dry side of the mountains.
Diagrams will vary.
Chalk is made from:
A. trillions of microscopic plankton fossils
B. finely ground sand
C. ground up seashells
A. trillions of microscopic plankton fossils
Draw 2 quick diagrams of a catapult - one where the potential energy is the greatest and one where the kinetic energy is the greatest. Label them.
High potential energy: catapult is pulled back but not released.
High kinetic energy: catapult has been released and object is flying through the air.
Why is a virus not a living organism?
It doesn't have many of the organelles that cells have.
Draw a simple diagram of a skater on a ramp.
Label where the skater has the most potential energy.
Label where the skater has the most kinetic energy.
Diagrams will vary.
1. What two factors contribute to water density? (think about convection currents in the ocean)
2. What is the densest type of water (use the two factors from #1 to answer)
1. Temperature and salinity (saltiness)
2. Colder and saltier water
About how long does it take for sunlight to travel from our Sun to the Earth? (you must be within 2 minutes to get points)
8 minutes 19 seconds
