The Science of Car Crashes
Car crash testing started in this decade.
What is the 1990's
40 miles per hour roughly translates to this Canadian speed.
What is 64 km/h
The body contains an average of 37 _________ cells .
What is trillion?
Hydraulic systems have four components:
A reservoir to contain the Hydraulic Press Fluid
A valve to govern the pressure and flow
A cylinder to transform the circulating fluid into energy
and this.
What is a pump? (to drive it through the system.)
DNA Connection: Humans share ___% genetic likeness to chimpanzees. (hint, it's in the 90's)
What is 96%?
True or false - should you touch the car right after the crash test?
False
.Calibrating a 'dummy' is attempting to replicate this animal as close as possible.
What are humans?
Thecell's genetic instructions are contained in this part of the cell.
What is the nucleus?
Hydraulics don’t create new energy; true or false.
TRUE what the system does is transform existing already present into a new form.
Sound travels _____(this single digit) times faster in water than it does in air.
What is 4 times faster?
This is how many cars they buy for each testing of a certain model.
What is 4?
Of bone density, body girth, hair length, height, mass distribution, this one does not affecting crashes
What is hair length?
Ribosomes, chloroplasts, Golgi apparatus and others, are all called something that is similar to what humans cal the live, heart, kidneys etc.
What are organelles?
Hydraulics produce three types of energy:
• kinetic—caused by moving liquids
• heat—caused by resistance to the flow
• potential—caused by pressure
We did this one with our machines.
What is potential hydraulics?
Although trees are fantastic, many mistakenly say they give us the most oxygen when it actually comes form these.
More than half of the world’s oxygen is produced by the ocean life. (plankton, seaweed, algae etc)
This fraction is how fast a crash happens.
What is 1/10 of a second?
The crash test facility is a non-profit operation; true or false.
What is true?
This tool has come a long way in allowing humans to study cells at a molecular level.
What are microscopes?
This is what we called our journey in creating our hydraulic machines.
What is the scientific method? (Scientific inquiry, or something close to that, works too.)
Humans have inherited genes from other species; true or false.
What is True?
(Our genome contains up to 145 genes mutated from bacteria, fungi, other single-celled organisms, and viruses.)
The high speed cameras are taking this many pictures per second.
What is 500?
This is the type of energy that they are witnessing beginning with 'k'.
What is kinetic energy?
Although plant cells and animal cells share many similar parts, this is a differnce.
What are plant cells having a cell wall?
We didn't actually build fully functioning machines but rather this.
What are prototypes?
The world’s smallest birds, agile fliers at 200 beats/sec. are these.
What are hummingbirds?
