air resistance
this is a limitation or a restriction
constraint
this is the weight the parachute carries
load
a variable is
likely to change
this connects to the canopy load
suspension lines
the engineering and design process consist of four steps which are
ask,imagine,plan, and improve
earth takes about 365 days to
revolve around the sun
when the earth spins on it's
axis it rotates around the sun
it takes the earth
1 day to complete a full rotation
the tilt of the earth and the revolution of the earth around the sun causes changes in

some of a piece of wood and how smooth it is
properties
some that can be used to make are concrete,flat rocks, and gravel
materials
is anything that people make to solve a problem
technology
when you a chair you need to think about how big and how strong it needs to be
design/build
are people who use math, sience,and imagination to solve problems to meeta and solve human
needs and wants
engineers
