Paragraph 4.6

Slide 1 - Diapositive

The Kingdom of Animals

Slide 2 - Diapositive

The Kingdom of Animals
  • Today, we will be discussing the Kingdom of Animals
  • This is a long paragraph, so we will divide it and take 3 lessons to finish it
  • Take notes, so make sure your notebook is out!

Slide 3 - Diapositive

Lesson Goals
  • You can explain what the characteristics are of species that belong to the kingdom of animals
  • You can explain the differences between vertebrates and invertebrates
  • You can name the characteristics and some examples of sponges, cnidarians, worms, molluscs and echinoderms

Slide 4 - Diapositive

Do you remember what the five kingdoms were?

Slide 5 - Question ouverte

Kingdom of the Animals..?

Slide 6 - Diapositive

What would you say when someone asks you what an animal is?

Slide 7 - Question ouverte

Animal: Cambridge English Dictionary
What's not correct about this definition?

Slide 8 - Diapositive

Animal: Cambridge English Dictionary
And this one?

Slide 9 - Diapositive

Animal: Cambridge English Dictionary
And these?

Slide 10 - Diapositive

Animal
In biology and in language, we might describe animals differently. In biology, we prefer the definition as described in the image:


Slide 11 - Diapositive

Animal definition Biology
Animals are multicellular     organisms that:
  • Always have cell membranes and a nucleus, but no cell wall
  • Always have to find and take in food (plants don't, remember?)
  • Always reproduce sexually, which means that there are always 2 parents
Multicellular = more than one cell

Slide 12 - Diapositive

Two big groups
  • Within animals, we have two big groups, vertebrates and invertebrates

Slide 13 - Diapositive

Invertebrates
  • Don't have a backbone
  • No endoskeleton

  • Some invertebrates have a skeleton (exoskeleton) and legs, others don't

Slide 14 - Diapositive

Vertebrates
  • Have a backbone
  • Endoskeleton

  • The backbone makes them strong, which means that they can grow bigger than invertebrates

Slide 15 - Diapositive

Today we will be discussing the invertebrates without a tough skeleton! (to which both SpongeBob and Patrick belong)

Slide 16 - Diapositive

Five groups today:
  • Sponges
  • Cnidarians
  • Worms
  • Molluscs
  • Echinoderms

Slide 17 - Diapositive

Sponges
  • Simple cell layers (bilayered animals
  • Live in the sea
  • Feed by filtering water (see next slide)

Slide 18 - Diapositive

Slide 19 - Vidéo

Cnidarians
  • More complex than sponges
  • Hollow, sac-like bodies (hydroskeleton)
  • Known for their cnidocytes, special cells that help them hurt enemies and catch prey (has anyone ever been stung by jellyfish?)

Slide 20 - Diapositive

Slide 21 - Vidéo

Worms
  • Flatworms, roundworms and segmented worms: three different types
  • Live in the sea and on the land (or even inside other animals)
  • In the image: a flatworm in the sea

Slide 22 - Diapositive

Slide 23 - Vidéo

Molluscs
  • Use an exoskeleton in the form of a shell
  • Snails, clams, oysters, octopuses and squids all belong to this group
  • Very big group!

  • Octopuses have their shell inside their body, but it's still an exoskeleton!

Slide 24 - Diapositive

Slide 25 - Vidéo

Echinoderms
  • Examples: sea urchins and starfish 
  • Hard, spiny covering
  • 5 identical parts
  • Tube-like feet

  • There is even one species of echinoderms that are called sea cucumbers! (see image)
Sea urchin = zee-egel
Starfish = zeester

Slide 26 - Diapositive

Slide 27 - Vidéo

That were all groups!
  • Sponges
  • Cnidarians
  • Worms
  • Molluscs
  • Echinoderms

Slide 28 - Diapositive

Now to the most important question..

Slide 29 - Diapositive

To which two groups do SpongeBob and Patrick belong? And Octo?

Slide 30 - Question ouverte

Now you can never say that you don't learn anything important in biology ;)

Slide 31 - Diapositive

And now what?
Go to part 2 of the planner and make sure all your notes are complete:
  • General explanation of each taxonomic group
  • Example species for each taxonomic group (including food habits, habitat, reproduction and a fun fact)
Part 3: take 5 pictures of animals in the groups we discussed today (see the planner on SomToday for more information)

Slide 32 - Diapositive

Questions?
  • Ask your classmates
  • Send me a message via somtoday
  • Ask during the lesson that you're at school
  • Or ask it in the next slide!

Good luck! See you next time (maybe)

Slide 33 - Diapositive

Ask any question about the paragraph here. Other questions: message on SomToday!
