4. How can light pollution hurt animals?
Artificial (manmade) light affects
wildlife (animals). Here are some of
the ways light pollution can hurt
wildlife, that is, nature.
One way is hurting sea turtles. Sea
turtles bury their eggs at night in
one spot. They follow the moonlight
to find their way back again and
again. Manmade light confuses
them.
Another way light pollution hurts
animals is by changing the way
animals hunt. Animals like owls
hunt at night. Light pollution can
make this hard.
http://todaysfacilitymanager.com/facilityblog/wp-content/uploads/hk_pollution1.jpg Yet another way light pollution
causes a problem is by making it
hard for animals to give birth to
offspring, which means babies.
Artificial light can cause many
problems for wildlife.

making dots on your paper.
Now open your eyes. Look at all
the stars you created in the
universe. Pretty cool!
Then, use your imagination to
create some constellations. Think
about what shapes you see.
Last, create a story about your
constellation. This is just like the
story of the constellation Orion.

17. Magnitude Matching Game!
First, cut out the magnitude charts.
Next, cut out the labels.
Then turn over all the card. Mix up all the cards.
After that, organize the cards.
Finally, flip over two cards. Do they match?
Keep them. If not, put them back in the pile!
