How many insect orders are there?

Are all scorpions poisonous and deadly or just some?



The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning “spiny skin.”

Echinoderm? What does that mean? “Echino” means spiny and “derm” means skin. You may have heard of your epidermis. That’s your outside skin. The creatures in this group all have some type of spiny structure on the outside.

What are Coelenterata?

One of the 7 Phyla of Invertebrates, Coelenterata (So-Len-Ter-ata) or Coelenterates (So-len-ter-ates)

Coelenterata is an obsolete term encompassing two animal phyla, the Ctenophora and the Cnidaria. The name comes from the Greek “koilos”, referring to the hollow body cavity common to these two phyla.

For follow-up work please research 1 of the following:

  • hydra,
  • jellyfish,
  • sea anemones,
  • corals

Charles Darwin and the Voyage of the HMS Beagle

For Biography study this year, I have chosen Charles Darwin for the following reasons:

1. He is the father of evolution which is basically the foundation of our Timeline of Life and our Second Great Story.

2. South America is one of the continents we will study as a class. Darwin’s time in the Galapagos Islands, off the coast of Ecuador, and time in South America was key to his scientific discoveries.

3. It opens the door to further biographical study of other famous scientists. We own numerous copies of other books in the “Who Was…. ” series.
