Milking
a snake takes careful work. Scientists don’t just jam their hands in the
snake’s mouth. A snake will bite anything that is pushed into its fangs!
Instead,
a scientist holds a snake near a glass container. The scientist must press the
snake’s head. The scientist has learned to squeeze the snake’s head just right,
so that the snake opens its mouth. Then the snake bites down on the container.
As the snake bites, the venom squirts out of its fangs and into the container.
Snakes
are milked many times after the initial, or first, collection. The venom is
saved and used to make medicine. That makes milking a snake worth the risk of
being bitten by one!
Activities:
1. Draw pictures to illustrate how snakes are milked.
2. Snake milking is a very dangerous job. Do you think
that it is worth taking risks to do it? Discuss with your learning partners.
3. Snake venom have been used as medical tools for
thousands of years especially in tradition Chinese medicine. Are you curious
about the medical benefits snake venom? Watch the video to learn about it.
Are turkey vultures turkeys? Actually, they are not! They
got their name because their bald red head looks like a wild turkey’s. They are
more closely related to herons, storks, and flamingos. Turkey vultures eat dead
animals, anything from small roadkill to dead cows.
Adult turkey vultures have a six-foot wingspan! These
huge wings let turkey vultures glide in the air for hours without ever beating
their wings. This allows turkey vultures to get a full and spectacular view of
all the dead things they can scoop up.
Turkey vultures have a great sense of smell, which is
rare for a bird. They can get a whiff of rotting roadkill while soaring
overhead and zero in on it with pinpoint precision.
Turkey vultures rarely kill, and they have an unusual
way of fighting, too. They vomit as their defense, and what they throw up
stinks.
These huge birds aren’t built for fighting. They have
weak feet and can’t hold on too much with their talons. That’s why dead meat is
a turkey vulture’s preferred meal.
Dead animals can make birds, cats, dogs, and wild
animals sick and spread disease. However, a turkey vulture’s digestive system
kills off any viruses or bacteria it eats. Turkey vultures don’t get sick when
they eat decaying flesh! Their droppings are also clean and free of disease. Turkey
vultures are nature’s cleanup crew!
Activities:
1. Why are the turkey vultures called the nature’s
cleanup crews? What make them the nature’s cleanup crews? Discuss with your
learning partners.
2. Make a turkey vulture shape by tangram pieces. Count
how many triangles your turkey vulture shape has.
3. Draw a turkey vulture that is cleaning a roadkill.
Then watch the video to learn more about vultures.
