The two worlds exist together,
but they are different.
Try It!
Look at the pictures. On a piece of paper, write
down all the things that are part of the natural
world. On another piece of paper, write down
all the things that are part of the human-made
world.
Work with a friend or make teams! Try to
think of five more things from each world,
human-made and natural. You will come up
with the best ideas and have the most fun when
you
collaborate
