2.1 Different kinds of animals

• Middelbare school
• vwo
• Leerjaar 1

Welcome to chapter 2!

This chapter is about animals, which groups they can be divided in, and how animals work. We will only discuss paragraph 2.1, 2.2 and 2.3. This is because we only have half a year, so we do the most important ones only.

Planning

• Lesson goals
• Introduction to chapter 2
• Paragraph 2.1
• Explanation 'how to make a summary for
  biology'
• Homework!

Lesson goals

• You can name the three different types of animals we can identify, based on the amount of cells they have
• You can make a summary of a biology paragraph

Chapter 2

In biology, we love to put organisms into groups. In this chapter, we will discuss which groups we can put animals in, based on several characteristics.

Characteristics:

• How many cells their body has (2.1)
• How they move (2.2)
• How they eat (2.3)

Chapter 2

During this chapter, we will also learn how you can make summaries of paragraphs, since this is different than you learned in Dutch lessons.

We will practice that a few times!

Paragraph 2.1

To prepare, please read the paragraph first. If you have done that, please proceed to the next slide.

Drag the correct definition to the correct animal type!

Unicellular

Bilayered

Complex

Animal that consists of one cell

Animal that consists of two layers of cells

Animal that consists of more than two cell layers

Unicellular animal

• Uni = one
• Unicellular = one cell 

• Functions for life are performed by cell organelles
• Live in aqueous environments (water)
• Example: Amoeba

Next slide =  a video about amoebas!

Bilayered animals

• Bi = 2
• Bilayered = 2 layers

• Functions for life are performed by specialised cells
• Live in aqueous environments (water)
• Example: Hydra

Complex animals

• More than 2 layers of cells
• Also called multicellular

• Functions for life are performed by specialised organs
• Live on land and in the water
• Example: humans, sea squirts, ...

That was paragraph 2.1!

Now I will explain to you how to make a summary of this paragraph.. It's a little different than how you learned it in Dutch, because biology is a different subject!

Making a summary

I will show you how to make a summary of this paragraph. Next paragraph (2.2), we will do the same (together), and the following one (2.3) you will do yourself!

What is a summary?

Making a summary means writing down the most important parts of a paragraph (we call these the key points). This gives you an overview.

How do you start?

• Very easy: the title of your summary should be the title of the paragraph you're making a summary of. To show that this is your title, you could give it a colour or make it bigger/bold if you want.
• So:
• 2.1: Different kinds of animals

Step 2: Read the paragraph

• Read the paragraph, and try to figure out what it is about. Have a look at all the subtitles in the paragraph, and all the other bolded words. 

• In this one: Unicellular animals, bilayered animals, ...

Step 3: Introduction

• Each paragraph has an introduction. Your summary should too. Find the most important sentence in the introduction, or make your own sentence.

• In this one:
• Animals can vary from simple animals, consisting of one cell, to very complex animals consisting of billions of cells.

This is what you should have by now..

Step 4: Find the logic

• When you read the paragraph, you're going to look for the logic in the text. Often, the bigger bolded titles help you with that. This means that the text is divided into several parts.
• In this one:

1. Unicellular animals
2. Bilayered animals
3. Complex animals

Step 4: Find the logic

• In this case, this means that the paragraph is divided into three parts. Your summary should then also be divided into three parts. 
• You can show this in your summary by separating them with space (so leave a line white between the parts), or by giving each one a different colour.

Step 5: Summarize each part

• Part 1: Unicellular animals
• First, you write down what the title means (what is an unicellular animal?)
• You can find this in the text!
• So:
• A unicellular animal is an animal that consists of one cell.

Step 5: Summarize each part

• Part 1: Unicellular animals
• Second, you see if there are other characteristics of unicellular animals in the text that seem important
• Write the characteristics down, you could use bullet points for them.

• If there are many long sentences, you are allowed to make them shorter, as long as you still understand what you mean!
• You can also add extra information if you think it makes it more clear

Step 5: Summarize each part

• Part 1: Unicellular animals
• Second, you see if there are other characteristics of unicellular animals in the text that seem important
• So:
• These animals do not have tissues, organs and organ systems
• They have small, specialised cell organelles that perform the necessary functions of life
• All unicellular animals live in aqueous environments such as ponds or ditches

Step 5: Summarize each part

• Part 1: Unicellular animals
• Last, often you can make the explanation more clear with an example. The book (almost) always does this as well.
• So: write down an example!

• Example: amoeba, paramecium

Unicellular animals

Step 5: Summarize each part

• Repeat this for the other two parts!
• The easiest way to do this is to see if there is information in the other two parts that is similar to the one you found in part 1.
• If you need to add more, you can always do that. But remember: it is a summary, so keep it as short as possible!
• If there is information that you already know, you are allowed to leave it out

Step 5: Summarize each part

• Try this for yourself, and then have a look at my summary (next slides) to see if you have something similar

Bilayered animals

Complex animals

Step 6: check your summary

Done? Read the whole summary and see if it is complete

• If you want to make things more clear, you can underline the important words in a sentence!

• This was a lot of information at once. Next lesson, we will do the same for paragraph 2.2, but then together! In the last slide of this lesson I have included my own summary. 

Homework!

• Make exercise 1-7 of paragraph 2.1 to see if you understand the paragraph
• Read paragraph 2.2
