From
Presentation to Programming
Revisited
By Cathleen Galas
Students
at Seeds University Elementary School, UCLA, created a
virtual aquatic
environment using MicroWorlds 2.0 by LCSI.
MicroWorlds is based on the Logo programming language.
Some examples
appeared in the December/January 1997–98 issue of
Learning
& Leading with Technology. The screen shots
provided here
show more of the students' work.
In
this simulation, a fish leads the user through the ocean.
The fish
is nearly eaten by a white shark, notes the krill and
which ocean
residents eat krill, comes in contact with other ocean
life, and
finds evidence of oil pollution in the ocean.
This
simulation illustrates the relationship between jellyfish
and shepherdfish.
The shepherdfish swims safely among the jellyfish
tentacles, attracting
other fish to the jellyfish. The two fish help each other:
The shepherd
fish attracts food to the jellyfish, and the jellyfish, in
turn,
protects the shepherdfish from its predators.
This
simulation shows a ship dumping toxic poisons into the
ocean. A
fish is swimming nearby. The next screen shows the effects
of the
toxins on the fish in the water.
In
this simulation, the person is walking on a sidewalk and
inadvertantly
kicks a can containing a toxic substance into a storm
drain. The
next frame shows the can coming out of the drain into the
ocean
where fish are swimming.
The
fish swims, then dies. It floats to the bottom and then
floats to
the top of the ocean.
