The American flag has 50 stars on it because there are 50 states.

Third Commandment

We just learned the Second Commandment to not take God's name in vain.

The third commandment God gave to Moses is:
Thou shalt sanctify the holy-day.

(from: wikisource - Luther's Small Catechism)
This means you should take one day out of each week, like Saturday or Sunday, to worship God.

Solar System

Our sun and the planets that spin around it are called our "Solar System"


There are other stars in the universe that have planets around them called "Planetary Systems", but the word "Solar" is just for our sun.

Pistons

We just learned about Hardware and Software.

Let's learn a little about car engines.

Inside a car's engine is something called a piston.
It is inside a small metal tube, and it moves up and down.
When it moves up, it squishes the gasoline in the tube (which comes from the gas tank) and electricity comes from the spark plug and BOOM the gas explodes.

The gas explosion pushes the piston down, and that pushing over and over again is what makes the pistons run the engine and spin the wheels.

Giraffe Horns

We just learned a little about what is Inside Bees

Let's learn about giraffes! The horns on a giraffe's head are called "ossicones".

A female giraffe's ossicones have fuzzy black hair, and a male's are usually bald.


(From: Wikipedia - Giraffe)

The males will use their ossicones when fighting (or "necking") with other giraffes.

Lumbar Vertebrae

We just learned about the Thoracic Vertebrae.


The five vertebrae in your lower back are called the "lumbar" vertebrae.

To help remember that, think of your back hurting so you put your hand on your lower back, and you have five fingers on your hand.
L is for lower and lumbar, and five fingers for five vertebrae!
