Cold Front

We've learned that water vapor can get lifted up into the air to become clouds by things called weather fronts.

One type of front is called a cold front.
It's when a whole bunch of cold air is moving along together in the wind in one direction.

When the cold front hits a bunch of warm air, it is heavier than the warm air.
So the warm air lifts high up into the air.
Almost like a shovel pushing along, the cold air stays low and the warm air goes high.

Remember that the warm air can be full of water vapor, and now that water vapor is high up in the sky where clouds start forming.

When the weather scientists want to show cold fronts on a map, they use blue triangles on a line, with the tip of the triangle pointing which way the cold front is moving.

Spider Hearts & Blood

We just learned a little about Spider Lungs.

Spiders have hearts up along the back side of their lower body, on the part called their abdomen.

Spiders don't have normal blood like we do, they have something called hemolymph.
It's kind of like our blood, but it's a blue or grey color instead of red, and it has different kinds of nutrients in it.

Our heart pumps blood to all the parts of our body in tubes called veins and arteries.
Spiders have a heart and some smaller tubes for their hemolymph, but mostly they just help dump it out on all the inside parts of the spider's body.

Left Atrium

We've learned that our blood gets filled up with good oxygen in the capillaries by the lungs, and then goes through tubes called the pulmonary veins toward the heart.

The oxygen filled blood, sometimes called oxygenated blood, enters the heart at a place called the left atrium.

The heart is divided up into four parts, called chambers, and the atrium is one of those chambers.

Delaware

Delaware is a state on the northeast part of the US, right on the Atlantic ocean.

The flag of Delaware has a tan colored diamond on a blue background. These were the colors that the first US president George Washington wore when he fought in the war for America's freedom.

The flag shows the date of December 17, 1787 because Delaware was the first state in the USA to ratify the US Constitution. That means they were the first ones to agree to all the rules made for our country.

There is a shield in the middle that has wheat, corn and an ox for Delaware's farming.
A ship is shown because Delaware was famous for making ships, and it is right on the ocean.
There is a blue stripe for the Delaware river.
Two people are on the flag, one is a farmer and the other is a soldier.
The flag has the words Liberty and Independence.

Delaware Bay is a large bay of water right next to Delaware that is a very important place for ships to come in from the ocean.
It is the second busiest place for ships, right after the Mississippi river.

Plans to kill Jesus

We just learned about Jesus' Transfiguration.

After Jesus had done many miracles and taught people using parables, some of the people in those days didn't like what Jesus was doing.

Some of the leaders were upset because people were following Jesus instead of them.

So they started making plans to have Jesus killed, because they could not stop him from doing miracles and teaching people.

The Persistence of Memory - Salvador Dali

We just learned about the famous painting The Scream of Nature by Edvard Munch.

Another very famous painting is called The Persistence of Memory by the artist Salvador Dali.

His painting was very strange looking, almost like something weird out of a dream where things are melting.
This painting was using something called surrealism which kind of means taking things from our dreams or imagination and making real looking pictures out of them.

The painting has pocket watches that look like they are melting.
Some people think this painting says something about the way we think about time.
Is it really as simple as we think, where clocks just ticks on every second?
Or can we bend time, mush it around, speed it up or slow it down?
Salvador Dali said he thought of the idea to paint them that way by watching some cheese melt in the sun.
