Case study: Bats

Bats are nocturnal animals. They can live in different environments but they need a place to roost.
The roost is the place where they spend the day and where they hibernate. You can find bat
roosts in caves, trees and inside empty buildings.
Most bats eat insects. A bat is able to eat one-third of its body weight in insects every night.
This means it eats several hundred insects in a few hours.
Some bats eat fruit. Vampire bats feed on blood.
Bats hunt for food at night. This means there is less competition for food since other animals
that eat insects or fruit hunt during the day.
Bats use sound to fly safely and find their prey. They make very high-pitched sounds which
humans cannot hear.
The main predators of bats are falcons and hawks.
Bats have light bones with webbing between which allows them to fly. They sleep upside down
and fold their wings to cover themselves.
In late autumn it gets colder and there are no longer insects and fruit for the bats to eat.
At this time of year bats look for a suitable place to hibernate. They often migrate long distances
to find the right place. The bats hibernate for up to six months. Their body functions slow down
so much that some bats only take one breath every two hours! They hibernate in groups with
many bats holding on to each other. This huddling behaviour helps to keep the bats warm.
Sometimes there are a million bats in one big cave.

Thanksgiving

A Time for Thanks... and Reflection: The Story of

Thanksgiving is like, the most American holiday ever, right? We picture Pilgrims, turkeys, and a big

feast, all about being thankful. But there's way more to it than just that. It's got a long history, and

not all of it is as simple as the stories we hear in elementary school.

Harvest festivals and giving thanks have been around forever. Think ancient Greeks honoring

Demeter or Jewish celebrations like the Feast of the Tabernacles. Even way back in 1607, British

colonists in Maine gave thanks for arriving safely. But the Thanksgiving we know today? That story

gets a little more complicated.

Some people think the first Thanksgiving actually happened in Virginia in 1619. A colony called

Berkley Hundred held a religious service to celebrate their ship's arrival and said they'd do it every

year. But that colony didn't last, so the Pilgrims got all the credit. The Pilgrims, who landed near

Plymouth Rock, are usually credited with holding a harvest celebration with the Wampanoag tribe

in 1621. They ate things like lobster, clams, and, of course, "wild turkeys".

Here's where it gets tricky. The story we usually hear is all about Pilgrims and Native Americans

having a friendly meal together. But that's only one side of the story. Many Native Americans see

Thanksgiving as a reminder of what they lost when Europeans came to America. After that first

Thanksgiving, things changed quickly. There were massacres and wars, and Native Americans lost

their land and independence. So, for them, Thanksgiving isn't always a happy holiday.

Created with web.diffit.meIt's important to remember that history isn't always simple. There are different perspectives, and

it's good to hear them all. Some people might argue that focusing on the negative aspects of

Thanksgiving is disrespectful to the Pilgrims and the idea of giving thanks. They might say that it's

important to celebrate the good things in our history, even if they're not perfect. But others would

say that ignoring the negative aspects is disrespectful to Native Americans and their experiences.

They might argue that it's important to acknowledge the full history of Thanksgiving, both the

good and the bad.

Over time, Thanksgiving became more than just a harvest celebration. Presidents started

declaring days of Thanksgiving, and Abraham Lincoln made it a national holiday in 1863. The White

House even has its own Thanksgiving traditions, like the turkey pardon. The turkey pardon became

a tradition when President George H.W. Bush pardoned a turkey in 1989.

Today, Thanksgiving is a mix of traditions. We travel to see family, eat a big feast, watch parades

and football, and maybe even break a wishbone. Some people volunteer to help others in need.

But it's also a time to remember the real history of Thanksgiving, with all its complexities, and to

be respectful of different viewpoints. It's a time to be thankful, but also to think about the past

and how it affects the present
