Butterfly - Pupa


After a butterfly has hatched from it's egg, and eaten a lot of food as a larvae (or caterpillar) it goes off to find a place to hang out.

Caterpillars usually find the bottom of a leaf, and attach themselves to it with some silk.
After that they shed their outer skin, and underneath is a hard skin that becomes the shell they stay in for a while.
When they are in this shell they are called a pupa or sometimes a chrysalis.
They stay inside the chrysalis and start growing their wings so they can turn into a butterfly.

Pancreas


The pancreas is a part of the digestive system that is right next to the duodenum.

It is connected to the duodenum, and when food passes by it lets out chemicals that help your body control the amount of glucose (which is like sugar) it uses for energy.

It releases chemicals called insulin, glucagon, somatostatin and polypeptide.

Do not judge others


In Jesus' Sermon on the Mount he told his followers that they should not judge other people.

He said that we all do things wrong, so we shouldn't be judging other people because we are not perfect ourselves.

Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.

Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.

Silver


Silver, like gold is a very valuable metal that people use for jewelry.

It is the best metal at letting electricity go through it, and letting heat pass through it.
Silver is also sometimes used in teeth to fill in areas where dentists drilled out parts of teeth.

Unlike gold, silver does need to be polished to stay shiny. When silver gets dirty it is called getting tarnished.

Butterfly - Larvae


When a baby butterfly hatches from it's egg, it crawls out as a tiny worm called a larvae.

Another word for the butterfly larvae is a caterpillar.
Caterpillars spend almost their entire time looking for food. They mostly eat leaves.

Caterpillars don't have claws or teeth to fight with, so to protect themselves some have what look like scary eyes on their body, some make a stinky smell, and some are poisonous.

Duodenum


After the mushed up food comes out of your stomach through your pylorus, it goes into your duodenum.
Your duodenum helps mush up your food some more using special chemicals, it tells the pylorus when to close up and not let too much food through.

It also connects to other parts of your digestive system like your liver, gall bladder and pancreas.
Those parts of your body let out liquids and chemicals that help break your food up.

Sunspots


Sometimes if you look at the sun with the right kind of telescope, you can see dark spots on the sun.

This is caused by the magnetic field around the sun causing problems on the photosphere.

It creates some cold spots no the sun.
The normal temperature of the photosphere is over 10,000 degrees F, and the temperature of the sunspots can get below 5,000 degrees F.

That's still way hotter than Earth, but the difference in temperature makes a dark spot on the sun, and we call that a sunspot.

Gold


Gold is a very valuable metal, and we use it a lot in jewelry because it is shiny and pretty.

One of the reasons it works so well in jewelry is because it is the most malleable of all metal.
That means you can smash it with a hammer and it won't break into pieces, it will just flatten or change shape, kind of like a really hard piece of clay.

Gold also does not change when it is out in the air or when it gets wet, like the way that copper turns green unless it is polished all the time.

It is also a very good conductor of electricity, so it is used in computers and circuits a lot.

Because gold has so many uses and is so pretty, it has been used as money in the past.
People still will pay lots of money for gold no matter where in the world you are.

Butterfly Eggs


Butterflies are beautiful creatures, and we know they come from caterpillars, but how?

Butterflies lay eggs on to a leaf, and the eggs stick to the leaf with a special glue. The eggs are protected by a hard outer shell called the chorion, and they are made waterproof with some wax.

The eggs usually hatch in a few weeks. If the eggs are laid close to winter time, they will hatch in the spring.

Mercury


When we think of metals, we think of heavy hard things, like iron or copper.
Those are all solid metals.

Mercury is a very special metal that is a liquid at normal temperatures!

All metals can be melted down to be liquid if they get hot enough.
The temperature they turn to liquid at is called their melting point.
Most metals have to get very hot to turn to liquid, like iron needs to be 2,800 degrees F.

Mercury stays liquid at normal room temperature, and won't turn into a solid until it gets super cold -37 degrees F.

Another interesting thing about mercury being a liquid, is that some metals are lighter than mercury, and the metal can actually float on top of the liquid.

Mosquito larvae


We've all seen those nasty mosquitos flying around, but you might wonder what baby mosquitos look like.

Like many other insects, mosquitos go through 4 stages: egg, larvae, pupa, adult (also called imago).

The adult mosquitos lay their tiny eggs in the water.
Eventually the eggs hatch and turn into mosquito larvae, which look kind of like long tiny skinny fuzzy caterpillars in the water.
The larvae swim around in the water eating things like algea and bacteria, things we consider garbage but they eat for lunch!
They breathe air through their body with holes on their bodies called spiracles or siphons.
If mosquito larvae are living in an area that has a cold winter, they can actually get frozen solid in the water, and survive until the next spring to grow again.
This is called diapause.
mosquito larvae
(from: wikipedia - mosquito)

When the larvae get enough food, they turn into a pupa, which looks sort of like a comma shape.
The pupa doesn't eat, it just stays in the water and works on changing its body, kind of like a caterpillar turns into a butterfly.

Eventually the pupa gets big enough, cracks through its shell and then out flies a grown up mosquito, off to bite someone!

Mosquitos are annoying, but they are very important for wildlife.
Many animals like fish, frogs, dragonflies, spiders and bats all eat mosquitos either as larvae or imago.

Eye for Eye


In the Old Testament, there was a law saying an eye for an eye, meaning that if you fought with someone and poked out their eye, then you would have to get your eye poked out in return.

This all was a way to keep people from being mean to each other so they didn't get punished.

When Jesus came along, he told people that if someone slapped you on one side of the face you should not hit them back.
Even more than that you should turn the other side of your face even if they wanted to hit you there too.

Osprey


The osprey is a large bird that lives near the water, and is such a great fishing bird it has nicknames like sea hawk, fish eagle, river hawk and fish hawk.

To catch fish, the osprey flies over the water, sometimes up to 130 feet above the water. When it sees a fish in the water, it dives down feet first and grabs the fish in the water with it's claws (sometimes called talons).
The osprey is very good at holding on to the slippery fish because it has two talons pointing forward and two pointing backward, so it can really grab the fish.
It also has sharp scales (called spicules) on the bottom of its feet, that are like spikes that keep the fish from getting away.
