Introduction to Animals Unit 4 Earth’s Organisms Lesson 5

Animals In your notebook, in the next 60 seconds, list as many animals that you can. After 60 seconds, I’ll type them out on the laptop/smartboard.

Animals In your notebook, in the next 60 seconds, list as many animals that you can. After 60 seconds, I’ll type them out on the laptop/smartboard. All the animals we’ve listed have the ability to move and consume food to get energy. All animals also share four other characteristics- multicellular, having specialized parts, reproduction, and maintaining body temperature.

Making Inferences Jellyfish, sponges, and octopuses are among the many invertebrates that live in the ocean. How do you think living in a water environment might affect their body shape?

Making Inferences Jellyfish, sponges, and octopuses are among the many invertebrates that live in the ocean. How do you think living in a water environment might affect their body shape? Some of these animals have a streamlined body shape to move quickly in the water. Some are porous so they can filter water to get food.

Finding Personal Vertebrae Do we have vertebrae?

Finding Personal Vertebrae Do we have vertebrae? How do we find our vertebrae?

Finding Personal Vertebrae Do we have vertebrae? How do we find our vertebrae? Put one hand at the center base of your skull and feel the bumpy bones. Next, put the other hand at your center back below your waste and feel the bumpy bones. If you’re able to move your hands toward each other, you will feel the bumpy bones as your hands get closer to each other.

If you’re able to move your hands toward each other, you will feel the bumpy bones as your hands get closer to each other. These bones are our vertebrae and similar structures can be found in all vertebrates.

That’s Diversity! In your notebooks and with your table, think of two examples for each of the following: Animals that crawl Animals that fly Animals that do not have bones Animals that live in the soil Animals that live in the ocean. Be specific- you would say praying mantis instead of insect.

That’s Diversity! The number of different animals that we just listed illustrates how diverse the animal population is!

Characteristics of Animals Let’s do a quick lab where we will create a sketch of a fictional animal with the characteristics that most animals share, and identify and label the specific and unique characteristics of your animal.

Introduction Welcome to the lesson, "Introduction to Animals.“ In this lesson, you'll learn to describe characteristics that differentiate animals from other organisms and from one another. EQ: What are animals? The vocabulary words for this lesson are consumer, vertebrate, endoskeleton, invertebrate, and exoskeleton.

Vocabulary Consumer: An organism that eats other organisms or organic matter Vertebrate: An animal that has a backbone Endoskeleton: An internal skeleton made of bones and cartilage Invertebrate: An animal that does not have a backbone Exoskeleton: A hard, external supporting structure

Animal Characteristics Look at the picture of the different cell types on page 342. How are these cells similar?

Animal Characteristics Look at the picture of the different cell types on page 342. How are these cells similar? They are all eukaryotic, have a nucleus, and organelles. How are they different? The shapes and functions of the cells are different.

Animal Characteristics Look at the picture of the different cell types on page 342. How are these cells similar? They are all eukaryotic, have a nucleus, and organelles. How are they different? The shapes and functions of the cells are different. If these cells are all animal cells, why are they so different?

Animal Characteristics How are they different? The shapes and functions of the cells are different. If these cells are all animal cells, why are they so different? Cell differentiation and specialization leads to different types of cells that are specialized to perform different functions.

Cell differentiation and specialization leads to different types of cells that are specialized to perform different functions. What are the six characteristics of animals?

Animal Characteristics What are the six characteristics of animals? Multicellular Reproduce Have specialized parts Move Consume food Maintain body temperature

Animal Characteristics What are the six characteristics of animals? Multicellular Reproduce Have specialized parts Move Consume food Maintain body temperature Do all animals reproduce in the same way?

Animal Characteristics What are the six characteristics of animals? Multicellular Reproduce Have specialized parts Move Consume food Maintain body temperature Do all animals reproduce in the same way? No, some animals reproduce sexually while others reproduce asexually. Some use both methods of reproduction.

Body Symmetry Look at page 344 and the images showing different body plans for animals. Why did the text use dotted lines on the images that show radial and bilateral symmetry?

Body Symmetry Look at page 344 and the images showing different body plans for animals. Why did the text use dotted lines on the images that show radial and bilateral symmetry? The dotted lines show you that if you cold fold the animal in half along the dotted lines like a piece of paper, then the two sides would match up exactly.

Look at the yellow box on the same page with the body coverings. Besides differences in body coverings, how else are these animals different?

Body Symmetry Look at the yellow box on the same page with the body coverings. Besides differences in body coverings, how else are these animals different? They are different in size and shape. They probably also have very different internal structures and move in different ways.

Classifying Animals Look at pages 346-347. What do the different branches on this diagram represent?

Classifying Animals Look at pages 346-347. What do the different branches on this diagram represent? Each branch of the diagram represents a different kind of invertebrate. Animals grouped together before a branch in the diagram share similar characteristics and DNA.

Vertebrates have an endoskeleton that gives their body support and provides a place for muscles to attach.

Summary Animals share six common characteristics. They are multicellular, have specialized parts, and maintain their body temperatures. Animals are consumers, and most reproduce sexually. Animals have the ability to move, at least at some point in their development. Animals are divided into two groups. Vertebrates are animals with backbones. Lizards, fish, salamanders, giraffes, and birds are all vertebrates. Invertebrates are animals that do not have backbones. Worms, crabs, octopus, insects, spiders, and sea urchins are all invertebrates.

Tonight’s Homework On a sheet of notebook paper folded in half, label each half (front and back) with the following: animal characteristics, animal diversity, invertebrates, and vertebrates. You should include a diagram or illustration for each as well as a description for each topic.
