3. Organisms are said to by living if they can R……………………………….

M………………………………

G………………………………

B…………………………….

4. Define the word dichotomous.

Processing Data and Information

These questions are about looking at information and trying to work out something new from it. All the information that you need is in the question. It is not likely that you will find the answers to these questions in your Science notebook.

5. Create a dichotomous key that would enable you to sort these clothing items into separate groups.

6. Using data

Use the lists of features of the invertebrate groups to state which group (or groups):

(a) has jointed and paired legs …………………………………………

(b) usually has a hard shell …………………………………………….

(d) has a body with many holes. ……………………………………….

Annelids, Platyhelminthes and nematodes are all worm-like in appearance.

Communicating Scientific Information

These questions are about putting information into appropriate formats. You may find some of the answers in your Science notebook. It is more likely that you will have to rearrange the information that you are given into a more suitable format.

We have been using a system of classification to sort all living things into smaller, more manageable groups.

Describe how the school’s student population is sorted into smaller groups. (This should only take two or three sentences. Remember each sentence begins with a capital letter is ends with a full stop.)
