Ions


We just learned a little about Mass.

A while back we learned about atoms,
and the parts inside of them protons, neutrons and electrons

Electrons have a negative charge, and Protons have a positive charge.

If an atom has more electrons than protons or more protons than electrons,
then we call it an ion.

If we know the number of electrons and protons, we can figure out whether it is more negative or more positive.

So if an atom has 4 electrons and 2 protons, then there are 2 more electrons.
This would give the atom a negative charge of 2.
An ion with a negative charge is called an anion.

If an atom has 6 protons and 2 electrons, then there are 4 more protons.
This would give the atom a positive charge of 4.
An ion with a positive charge is called a cation.

Wasps and Bees


We just learned about the Flying Squirrel.

Let's learn about Wasps and Bees.

When striped yellow bugs are flying in the air, it can be hard to tell sometimes if it is a bee or a wasp.
Maybe because there are over 100,000 types of wasps, and 20,000 types of bees!

The biggest difference you can notice is that most bees have some hair on them, and wasps have no hair.
Bees eat nectar from flowers, and wasps eat other bugs.
Most bees die when they sting you, and most wasps don't die and can keep stinging.

Even though we might be scared of bee and wasp stings, they do help us out!
Bees help make flowers grow, and wasps eat small bugs that can hurt plants and crops.

Here is a honey bee:

King Saul


Let's keep learning about the kings from the books of Samuel, Kings and Chronicles.
We already learned about the prophet Samuel.

Next up is King Saul.

Saul was a very handsome man, and led God's people to win battles with other people.

He later had problems because he was impatient.
When he didn't listen to some instructions God gave him through Samuel, God was angry.

Saul was also jealous of David, because people were talking about how great a warrior he was.
So he planned to kill David, but Saul's son Jonathan was David's best friend and he saved him.

Saul was eventually killed in a battle.

Constellations - Orion


We learned before about the constellation the Big Dipper.

Let's learn about some more constellations!

The constellation of Orion looks like a person, and if you connect the dots
and use your imagination you might be able to see someone who is hunting with a bow and arrow.

In old Greek stories (called mythology) Orion was a great hunter.

(from: wikipedia - orion constellation)

The best way to find Orion in the sky is to look for three stars together, these are part of Orion's belt.
