Animal Hooves
The
outer hoof (the wall and sole) are made of the same stuff
as fingernails - keratin. This part of the hoof grows vertically in little
tubes bound tightly together. Inside the hoof is a complex
system of bones, ligaments, circulatory structures, shock absorbing and supportive structures made of elastic cartilage.

is the branch of science that studies the properties, composition
and structure of substances, and their interactions with other
matter and with energy.
More simply, chemistry is the study of substances and how they
change.

Weather Satellites
A
weather satellite is used in weather forecasting. It records
cloud distribution and temperature to help to predict weather
patterns.
A
weather satellite is a cloud observation platform in space.
Satellites provide cloud observations day and night over
large regions. There are two main types of weather satellites:
geostationary satellites and polar orbiting satellites.
Geostationary
satellites orbit the earth at the same rate the earth
spins. They stay about 36,000 km (about 22,000 mi) above
a certain spot on the equator and are always monitoring
a specific region below them. Many pictures of clouds are
taken in a row, showing meteorologists
valuable information about the development, movement, and
dissipation (going away) of weather fronts, storms, and
clouds.
Polar
orbiting satellites, which sit about 850 km (about 530
mi) above the earth's surface. They pass over the North
and South poles on each orbit. They photograph the clouds
directly beneath them. Because the earth rotates beneath
the satellite, each orbit lets the satellite monitor an
area further west than the time before. This
way, the satellite photographs the entire surface of the
earth every 12 hours.
Polar
orbiting satellites observe clouds at a much lower altitude
than geostationary satellites, they provide more photographic
detail of cloud systems.
"Geostationary" means - 'Stationary (in one place) over a point on Earth': This word
describes the orbit of a satellite that circles the Earth
above the equator at the same speed as the Earth's rotation,
(so it looks stationary, or the satellite does). Most communications
satellites are in geostationary orbit.
"Polar"
means -
'Found in the regions surrounding the North or South Pole'.

Toothbrush
invention and history
People
have used different types of twigs, including ones from
the Neem tree, to clean their teeth since before recorded
history started. But the invention of the actual tooth brush
is more disputed. Many web site say it was invented in China
in 1498, but they don't say by who or where this information
comes from.

Care History - some info on the
history of the toothbrush and beyond!

Seasons
Seasons facts
Seasons on other planets
When where you live is tilted towards the sun, the sun "rises" higher in the sky, stays above
the horizon longer, and the sun's rays strike the ground more directly. This causes warmer weather too.

environmental and social justice campaigns. This is a
non-governmental, grassroots organization, which seeks
to raise environmental awareness, empower youth, develop
skills and open up venues for activism to young people.
*YES!
Youth for Environmental Sanity
YES! was founded by a 16 year
old and a 19 year old in 1990. According to their web
site: "Some young people believe growing up means
abandoning their ideals. To us, it means learning how
to live our ideals, every day, on the Earth. We believe
that if the passion, creativity and commitment of youth
can be liberated for the common good, we can transform
our world." If this sounds good to you, check out
their web site.

Waste
- a HUGE problem in the world
Packaging
Choices that Reduce Waste - great information on how to reduce,
for example:
-
Consider buying products that don't take much time to
separate into smaller servings. If you buy a box of instant
pudding, you can quickly prepare and divide it into single
snack servings that can be carried for lunches in reusable
plastic containers. You are throwing away less packaging--about
90 percent less by volume and nearly 75 percent less by
weight. Also, the instant pudding is less expensive than
the pre-made snack packs.
-
You might like the non-breakable plastic ketchup bottle,
but most of the time, the plastic bottle is made of multiple
or composite materials that cannot be recycled. An alternative
is to purchase one bottle of ketchup in the plastic container,
then refill it with ketchup from glass containers, which
can be recycled.
-
Instead of "paper or plastic," use a canvas
shopping tote or string bag. Or, if you've been saving
bags, bring your own to the store, including the small
plastic ones you can use for loose produce. Don't forget
to bring back extra paper and plastic bags to your supermarket.
Many stores will recycle both the plastic and paper bags
that are returned by customers.
Here are many things you can do to reduce
the amount of waste you produce:
- Avoid food packaged in individual servings. Buy in bulk.
It saves money and the environment.
- Buy multi-use items rather than single-use when possible.
- Use your own cloths bags for shopping.
- Donate your old clothes to charity.
- Buy beverages in refillable containers.
- Use rechargeable batteries.
- Share your newspaper, magazines and books with a friend
- or recycle them.
- Wrap presents in reusable cloth bags or reused wrapping
paper.
- Rent items you use infrequently.
- Compost
- Pack your lunch in reusable containers.
- Take leftover food scraps, and soiled lunch paper products home with you in your reusable container, these things can usually be added to your municipal organic waste box if you have one.
- Support your community's recycling programs.
- Buy products that contain recycled materials.
- Use
both sides of every sheet of paper, and then recycle when
no longer needed.
- Use
a durable refillable mug or glass at school or work.
