hull design at the navy yard

last May at homeschool at the navy museum
we learned about different hull types and their various strengths and weaknesses.
for example, large cargo ships usually have deep-v hulls
because they can travel through many different types of water
(i.e. shallow, rough or deep waters)
and can support larger payloads,
but ships with this hull type must travel at slower speeds
and use larger engines.

for their hands-on project
— and there always is at least one hands-on project
for every homeschool at the navy museum —
the younger ones built hulls out of thick paper and tape
and tested their hull’s payload capability with plastic baggies full of pennies.
the older ones designed and carved their hulls out of foam blocks,
and then evaluated their creations in a 12-foot water track.

THIS is what science is all about!

science = learn + think + do
