school

Hi Holden again. I'm going to tell you something I learned in math. I learned how to make two digit subtraction easier. Let's start. First you subtract the first two numbers on the right. If it's like 2-7 you can't do that. So you'll have to regroup. Take one number away on the left side at the top. So if it's like 5 it will now be 4. Then add one number to two so it will be 12-7. Then you just subtract all the numbers.

Complex Invertebrates part 2

Hey complex invertebrates again. Let's start. Arthropods are a type of invertebrate but they are smarter than the average mollusk or segmented worm. A arthropod has body sections. There's a head, a middle, and  wings. Arthropods have sections that do stuff like help them see and walk. Arthropods have this thing called an exoskeleton. It protects the inside of the arthropods body. I find that the exoskeleton doesn't grow with the arthropod part very painful. You know flies and centipedes their both arthropods. Their are two groups of arthropods one has two body sections the other has three body sections.


Gotta go.

Complex Invertebrates

Hey more and more invertebrates it seems like. Let's start. In my last post I told you about simple invertebrates. Well now we're talking about complex invertebrates. There invertebrates but they are much sophisticated. These guys have tissues that are there to form organ systems. Segmented worms are our next subject. They are another type of complex invertebrate. There are three worms that belong to this group. Earthworms,leeches, and clamworms. Guess what, all these guys live underwater.

gotta go.

school

Hi Holden again. I'm going to tell you things I learned in school. In reading,I learned how to make inferences. You make an inference by reading the sentence,than describe the character. That was a breeze for me. I hope in the future we'll do something more challenging. But I really liked it.





Later.

Simple Invertebrates Part 2

Hello Holden again It's part two of this lesson. Let's start.  Coral, jellyfish, and sea anemones all have one thing in common their all stinging celled animals. Don't get confused their invertebrates also. The animals use their tentacles to sting their prey, and then pull them forward to eat. O.k. are next subjects are flatworms and roundworms. Flatworms are soft body worms that are long and flat. That's the term flatworm. The flatworm have only one opening it's for eating and disposing waste. That's gross.  A  flatworm can live inside other  other bodies, and eat on their insides. Roundworms have bodies that are more complex than a flatworms. You know how I said that flatworms can live in other bodies. Well one type of roundworm lives inside of pigs. Flatworms and roundworms aren't so different if you look at it in different ways.

Simple Invertebrates

Hi it's Holden more invertebrates. If you haven't read my last blog about mollusks a kind of complex invertebrates I'll tell you one more time what an invertebrate is. An invertebrate is a type of animal that that has no backbone. I'm sure glad I have a backbone. But you know we're not talking about any kind of invertebrate.  We're talking about simple invertebrates. The simplest kind of invertebrate is a sponge. Not like Sponge bob he's a house sponge, but I mean sea sponges. You know something really cool if a part of a sponge gets damaged it the cells in it's body will give the sponge a new body.

Mollusks

Hello it's me Holden. Do you know about mollusks? Well if you do great but I'm going to tell you more. Mollusks are a really big group of animals such as octopus, snails, oysters and clams. Mmmm they sound good to eat. But back the mollusks. Mollusks are soft body invertebrates. That means that they have no backbone. If you've heard of snails you'd know they have shells. But you know an octopus doesn't have a shell even though it's a mollusk. You know that all the mollusks that I've mentioned are all things we eat.

                                
                                                                           Talk to you later.

                   

p.s. all animals that I've mentioned that are tasty have not been harmed in the making of this blog good by.
