We just learned about Coal.

Another fuel used for metalworking is called Coke.

Coke is made by taking coal and heating it up very very hot, sometimes over 2,000 degrees F!
It is baked and heated for a long time, sometimes for days.

When it is done, the coke is removed and then can be used as fuel for smelting, that will burn even hotter and faster than a wood fire or charcoal fire.

Panamanian Golden Frog

We just learned about the European Fire Bellied Toad.

Another type of frog is the Panamanian Golden Frog.

This frog is part of the true toad family.
Remember that all toads are frogs, but not all frogs are toads.
And some frogs are called toads, and some toads are called frogs.

The people in Panama love this golden frog, and put pictures of it all over the place.
There are even stories saying that when this frog dies it will turn to gold and bring good luck.
This frog even has it's own holiday, "National Golden Frog Day" on August 14th.

The skin of this frog is poisonous, and was used long ago to make poisonous arrows.

When this frog wants to talk to other frogs, it will wave its arms around.
Scientists think this is because the frogs live close to noisy rivers and couldn't really hear each other croaking well, especially because they don't really have normal ears and can't hear well.
