Review basics 5 + start basics 8

Goals: 

-I can use 2 characteristics to classify animals into phyla.

-I can classify animals from different phyla by comparing characteristics.

-I can recognise arthropods by using at least 3 characteristics.

Levels of classification

Animals belong to:

1. Eukaryotes
2. Archaea
3. Bacteria
4. Prokaryotes

We can classify animals into phyla based on:

1. Number of legs
2. Body shape
3. Symmetry
4. Type of skin

Show a picture of an animal with an external skeleton.

Show a picture of an animal with an internal skeleton.

Exercises basics 5 

-You will get 5 extra minutes to work on exercises 20 t/m 23 of basics 5 (only online!). Finished? Go the the purple slide (extra assignment).

Basics 5

-We will discuss some of the questions from exercises 20 t/m 23 of basics 5.

8: Arthopods

-Arthropods=geleedpotigen

Characteristics:

-Legs built up of segments

-A segmented body

-Complete external skeleton: cuticle

8: Arthopods

-Arthropods=geleedpotigen

-Most animals on the planet.

4 classes: 

-Insects=insecten

-Arachnids=spinachtigen

-Crustaceans=kreeftachtigen

-Myriapods=veelpotigen
