Twist Drill Bits


We just learned a little about Drill Bits.

One type of drill bits is the Twist Drill Bit.
For these bits, there is a spiral cut along the bit, and the taller that spiral is, the faster the bit is meant to go.
The more compact and shorter the spiral is, the slower the bit goes.

At the end of the bit is the "tip", and there are many different types of tips.
Some bits have a "brad point" which is a tiny little spiky point that holds on to the metal or wood so the bit doesn't slide around when it is drilling.
Some tips are very flat, and some are very pointy, depending on what you are trying to drill.

Gray Tree Frog


We just learned about the American Bullfrog.

Another type of frog is the Gray Tree Frog.

Many of the poison dart frogs we learned about were very colorful to warn off predators.
Other frogs that are not poisonous have to use camouflage to hide so they don't get eaten.

The Gray Tree Frog can also be green, black or white depending on where they live and where they need to hide.
They are tree frogs, and they almost never leave the trees.
These frogs are nocturnal, meaning they are awake at night, and sometimes can be found by windows and porch lights where bugs are flying around because of the lights.

American Bullfrog


We just learned about the Poison Dart Frogs.

Another type of frog is the American Bullfrog.
These frog get their name because they make a low deep croak that sounds like a bull's roar.

Just like there are some types of frogs called Bufonidae that are called "True Toads", there are also some types of frogs called Ranidae, that are called "True Frogs", and the bullfrog is a true frog.

Unlike a lot of other animals, the female bullfrog is usually larger than the male frog, and the male bullfrogs have yellow throats.
When a group of male bullfrogs gets together in a group, it is called a "chorus".
The male bullfrogs will all get together and croak to call out for female bullfrogs.

Bullfrogs can grow to be 6 inches long, and can jump 10 times their body, length. That means a 6 inch frog could jump 5 feet!

Hair Growth


We just learned about the Hair Follicle.

Human hair doesn't always grow at the same speed.
Sometimes it is growing a lot, sometimes it is slowing down, and sometimes it stops growing.

We know that the hair on our head grows longer than the hair on our eyebrows or eyelashes.
Each part of the body has different rules for how long the hair should grow, and when it should stop.

The time for growing of hair is called the anagen phase.
catagen is when the hair growth is slowing down.
telogen is when the hair has stopped growing because it is long enough.

The hair for your eyebrows grows for about 4 months and then stops, but the hair on a human head will keep growing at a normal speed for about 2-7 years!
Human hair usually grows about 6 inches every year, so after 7 years your hair would be four and a half feet long!

Psalm 23


We just learned about Psalm 22.

Another very famous chapter in the Book of Psalms is Psalm 23.

This chapter talks about God as a protecting shepherd.
Because this Psalm talks so well about being protected by God in times of need, it is put on a lot of posters, quoted a lot, and has been in a lot of music by famous people including Johann Sebastian Bach.

The Lord is my shepherd; I shall not want.
He makes me lie down in green pastures.
He leads me beside still waters.
He restores my soul.
He leads me in paths of righteousness for his name's sake.

Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me;
your rod and your staff, they comfort me.

You prepare a table before me in the presence of my enemies;
you anoint my head with oil;
my cup overflows.

Surely goodness and mercy shall follow me all the days of my life,
and I shall dwell in the house of the Lord forever.

Bamberg Horseman


We just learned about the Holy Thorn Reliquary.

Another Gothic Art sculpture was the Bamberg Horseman, made in Germany around 1225 AD.

This is a statue of a man riding a horse, and the man is either a king, emperor or saint, but no one knows for sure who it is supposed to be, because the history of it was lost or forgotten.

There were many statues of people on horses long ago, but for a long time people had stopped making statues like that until the Bamberg Horseman was made.

It is also one of the first statues to show the bottom of a horse's foot wearing a horseshoe.

Underneath the front part of the statue where the horse is standing is a sculpted face that looks like a man's face made out of leaves.
This type of sculpture is sometimes called the "Green Man" and can mean a lot of different things like respecting nature, the growth of spring, or maybe even mythological creatures.
