Chambered Nautilus


We just learned about the Common Octopus.

Another type of cephalopod is the Chambered Nautilus.

These cephalopods look sort of like snails, and they live in shells like a snail.
Inside their shells are chambers in a spiral shape where their body parts are squished into.

The top of their outside shell is dark on top and light on the bottom.
This helps them hide from predators, because looking down from above they blend in with the dark sea, and looking up from below they blend in with the sky above.

The nautilus grows from an egg, but they don't grow as a larvae like a lot of other cephalopods. They grow right from the start with a tiny shell, and the shell grows with them inside the egg until they hatch, about 1 inch long.

It is a meat eater, and it eats shellfish, but also eats garbage food floating around in the water or on the bottom of the sea.

They float up and down by changing how much water is in their shell.
If they want to go down, they suck in more water, and if they want to go up they spit some out.
You can think of it like a boat, that fills up with water and sinks, or empties the water and floats.

Phalangeal Ligaments


We just learned about the Metacarpal Ligaments that connect your metacarpal bones together in your hand.

The metacarpal bones in the hand connect to the finger bones called phalanges, and there are phalangeal ligaments connecting the metacarpal bones together, and the finger bones together.

The joints where the bones connect has padding to keep the bones from smashing into each other, and also keeps them stuck together so they can't be pulled apart.


(from: wikipedia - metacarpophalangeal joint)

The finger bones have ligaments that go over and under the fingers, to help your fingers stretch out or close into a fist.

Lion Capital of Ashoka


We just learned about the Woman of Samaria by William Henry Rinehart in Washington DC, in 1859.

Most of the art we've learned about has been from Europe, the Middle East, or Northern Africa.

Let's learn a little about some art from the continent of Asia.

One of the oldest sculptures is the Lion Capital of Ashoka.

This was made around 250 BC in India.
At that time there was an emperor named Ashoka who wanted to have symbols of his kingdom spread across the country, so he had artists make large pillars with sculptures on top and put them all over.
There are about 20 pillars left that have not been destroyed, and the Lion sculpture is the one that has survived the best of all of the sculptures.

It is a very important symbol in India. It has been put on the national emblem, and the lotus flower shaped bottom base of the sculpture is on the national flag.

Common Octopus


Let's learn about some cephalopods!.

One of the most famous ones is the Common Octopus.

Some funny things about the octopus are that while a lot of people say "octopi" for a group of them, the right word is actually "octopuses".

Also, people say that an octopus has tentacles, but they actually have arms.
The difference is that arms have suction cups all along them, and tentacles only have suction cups at the end.

There are about 300 different types of octopuses in the world!

These cephalopods can change color to hide, and they use their arms to grab their prey and use their beak to crack open any shells for animals they have to eat.

Woman of Samaria - Rinehart


We just learned about the statue of Benjamin Franklin by Hiram Powers in the US in 1862.

Another neoclassical sculpture is the Woman of Samaria, sculpted by William Henry Rinehart in Washington DC, in 1859.

William Henry Rinehart was born in Maryland, and grew up as a farmer. When he was about 20 years old he got another job as a helper to a stone-cutter, where he studied sculpture.

At 30, he moved to Italy to learn more about sculpture, and did some marble reliefs. He came back to the US a few years later and opened his own studio where he made a lot of marble and bronze sculptures for the US Capitol of Washington D.C.

Eventually he moved back to Italy and lived the rest of his life in Rome.

This famous sculpture of his is of the woman in the book of John in the Bible who came to the well to get water, and she met Jesus.
He asks her to get him some water, and then tells her he can give her eternal life.

Volcano tectonic earthquakes


We just learned about the Earthquake Swarm, a lot of earthquakes happening in the same area.

Scientists spend a lot of time trying to figure out what causes earthquakes.

We already learned about the big tectonic plates on our planet that crash into each other at faults

Another cause of earthquakes is from Volcanoes and tectonic plates.

We learned a while back about the melted rock called magma that flows around like hot water under a volcano before it erupts.

Sometimes that hot magma flowing around underground can put a lot of pressure on the rocks above it, and cause it to crack, causing an earthquake.
You can think of it like water in a water balloon, when you squeeze the water balloon it will pop!

Cephalopods


We've learned a whole lot about frogs, now let's learn about Cephalopods!

There are over 800 different kinds of cephalopods living in the world, and around 11,000 kinds of cephalopods that have gone extinct and are no longer around.

Some cephalopods are really famous, like the octopus or squid, but some you may not have heard of like ammonoids or nautilus.

The super science name for an animal is split up into these parts: Kingdom, Phylum, Class, and sometimes Subclass.
Sometimes there are even more parts like Suborder, Infraorder, Family, Genus or Species.
Humans are:
Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Suborder: Haplorhini, Infraorder: Simiiformes, Family: Hominidae, Genus: Homo, Species: H. sapiens

Scientists use these words to come up with special names for every single animal on the planet from mice to elephants.

Cephalopods are:
Kingdom: Animalia, Phylum: Mollusca, Class: Cephalopoda

The "phylum: Mollusca" actually means that an animal like an octopus is sort of related to a snail!

There are lots of different types of cephalopods, we'll learn about some fun ones next time!

Earthquake Swarm


We just learned about the Tsunami Earthquake that isn't very big but can trigger a tsunami.

Another type of earthquake is an Earthquake Swarm.

This is when a lot of earthquakes happen in the same area, and are clearly not just aftershocks or foreshocks from one single earthquake.

These can be hundreds or even over a thousand earthquakes in one state, spreading out over a time of days, weeks or months.
One of the ones that happened not long ago was in Nevada, with 1,000 earthquakes between February and November 2008.
