Solar - Photosphere


After the Sun's core, radiation zone and convection Zone comes the last part of the sun on the outside.

The photosphere is the outside shell of the sun, the part that we see that gives light to our planet from space.

The photosphere is super hot, at over 10,000 degrees F.

It is mostly made up of things called granules which are huge bubbles of plasma over 600 miles wide!

The granules rise up from the convection zone, then after about 8 minutes they cool off and go back down to a smaller size.

Lead


We just learned about the element sodium that is part of what we call salt.

Another chemical element is Lead, called "Pb" for short (from the latin word "plumbum") on the Periodic Table.

Lead is another type of metal found in the earth.

Just like graphite lead can be used to write on things.
It is also easy to work with and make into things like pipes, so for a very long time many water pipes were made out of lead.
Lead was also used to make paint for a long time.

People have now learned that lead can be poisonous to people, so we have stopped using lead for pipes or paint.

Lead is still used today to help protect us from radiation. When you get an X-Ray at the dentist's office or a doctor's office, they sometimes put a big heavy apron on you. Inside the apron is lead, protecting you from the X-Rays.

Lead is a very heavy atom, so it can stop any bad radiation from getting to your body.

Loon


We just learned about the Sea Anemone

Another type of animal is the Loon.

Loons are black and white birds that spend most of their life on water.
The name loon comes from old words that meant awkward or clumsy, because they do not walk very well on land.

Loons catch their food by swimming along and then diving head first into the water to catch fish, frogs, crayfish, snails and other small things in the water.
They are very good divers and they can hold their breath for up to 90 seconds while looking for food.

Loons don't have teeth, so sometimes they will swallow small rocks that will stay in their stomach, so if they swallow something with a hard shell like a crayfish the rocks will help slowly break the crayfish's outer shells and they can digest them.

The loon is such a famous bird that in Canada it is on their one dollar coin.

Stomach - Hydrochloric Acid


While the food that is in your stomach is getting mushed up by the peristalsis, it is also getting turned to mush by a chemical called hydrochloric acid.

This acid is so strong that if you had a glass of just hydrochloric acid and you touched it with your hands, it would burn your skin.

Luckily your stomach has this gooey slimy stuff in it called mucus all along the walls of your stomach that protect it from the acid.

The red, yellow and green colors are also on many other flags of countries in Africa.
The red is for the blood of the people who died fighting for freedom, the yellow is for the gold and other minerals that make a lot of money for the country, and the green is for the forests and nature of the country.
The black star is for the freedom of the African people.
The Ghana soccer team is nicknamed the black stars because of their flag.

Salt of the Earth


We just learned about the Beautitudes that Jesus talked about on his famous Sermon on the Mount.

Another thing that Jesus told his followers in his sermon is that we are the salt of the earth.

You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot.

In the time Jesus was speaking, salt was very important. It was used to help food stay fresh, to help make candles last longer, to help plants grow and to make food taste better.

Since it was so important, when Jesus told his followers they were the salt of the earth, he was saying they were very important, and that they needed to be the helpful flavor of the world and helped save people.
