You are a
paleontologist.
You have found this
skull
Problem is, that is all
you, or anyone else, has
ever found—just the
skull.
What did the
rest of him look
like?

Constructing Explanations & Designing
Solutions The top of a Pachycephalosaurus skull could be 9
inches thick, and much of the skull and the snout
were also covered by small bony knobs and spikes.
The size of the skull as a ratio of its body size means
it was probably 9 to 10 ft long.
Similar animals of that size and shape today weigh
about 250 lbs, so it probably did.
The dinosaur's distinctive domed cranium was so thick
and stout that it can sometimes survive as a fossil
when the rest of the skeleton degrades.
Some scientists think that it’s thick skull allowed
these animals to fight in head-butting battles compared
to bighorn sheep and other modern animals do. Scars
on its skull have been interpreted as reinforcing this
hypothesis, though other research is contradictory.
Pachycephalosaurus was an herbivore, probably fed on
low-lying plants relatively close to the ground.
Engineering Practices You Will employ…
Engaging in Argument from
Evidence
How do you know it looks like
that?
What data supports your
reconstruction?
Archeology investigation-“Is it really that
old?” Visitor plays the part of archeologistlooking at a fabric sample of something the
owner claims is thousands of years old.
Looks at the unknown under a slide against
a series of exemplars—what is it? Could
do similar activity with common
invertebrate fossils
--“How do we Know” lets visitors find out
how paleontologists reconstruct dinos. In
this case, they figure out what a
pachycephalosaurus looked like—from only
the skull (true story). Table with a lot of
possible dino parts, but the head is
permanently attached. From what they
know, the visitor uses investigation, math
skills and reasoning to reconstruct the entire
animal-just like scientists do

Climate
Change!
MS-ESS3-5 - ESS3.D Global Climate Change
Asking Questions:
How can there be global warming
when Kentucky just had one of the
coldest winters in years?
That’s the problem to be solved
Gather all the information (core concepts )
•Global warming is in fact, “global”
•Kentucky, with the rest of North America, is in the
Northern Hemisphere
•When its winter here its summer in the Southern
Hemisphere
•The Southern Hemisphere saw record heat this ‘winter’
•Not sure what else was going on in northern hemisphere
Explore the principals of weather and
climate
•Hot air rises; cold air sinks
• Hot air causes low pressure areas; cold air causes high
pressure areas
•Different air temps, like different water temps, have
different densities. Cold air is more dense than hot air
•Air tends to move from areas of cold towards areas of heat
•Warm water circulates from the equator towards the poles
We have the content, the data, the facts, the ideas…..
But its just a conglomeration of somewhat disassociated information
What next?
•Global warming is in fact, “global”
•When its winter here its summer in the Southern Hemisphere
•The Southern Hemisphere saw record heat but while we and much of the
US had record cold, there were other places in the northern hemisphere
that were average or above normal
•Hot air causes low pressure areas; cold air causes high pressure areas
•Different air temps, like different water temps, have different densities.
Cold air is more dense than hot air
•Hot air rises; cold air sinks
•Air tends to move from cold towards areas of heat- cold air moves
towards hot air
Group your data to start to see patterns-current events + basic
weather principals start to reveal a story
Create a Model
Could be as simple as sketching out
how hot air and cold air interact
Or perhaps an algorithm illustrating
the If / THEN relationship
What else?
A pie chart or bar graph could indicate
global temperatures in different places –
that’s computational thinking
And a good model
But you now have constructed a solution!!! That’s engineering
put into practice
Science finds explanations
Now I know how global warming works
Engineering finds solutions
Now I know why Kentucky can have a cold winter even with
global warming –and I can show you!
