DICHOTOMOUS KEY and PHYLOGENETIC TREE

Draw a phylogenetic tree that reflects the classifications made

Create a dichotomous key that includes the criteria used to divide the elements in the order used

Continue dividing the groups according to their characteristics until leaving each element alone

Do the same with the second group

Divide the first group into two subgroups

Divide them into two groups according to their characteristics such as shape, size, position, color, texture, material, function...

Choose 10 elements and search their images on the internet or draw them

PROCEDURE

1. Choose 10 elements and search their images on the internet or draw them

They do not work with electric power

They work with electric power

2. Divide them into two groups according to their characteristics such as shape, size, position, color, texture, material, function...

Not made of metal

Made of metal

They do not work with electric power

3. Divide the first group into two subgroups

They are not used to warm up

They are used to warm up

They work with electric power

4. Do the same with the second group

It is not used to cut

It is used to cut

His head is not pointing

His head is pointing

Made of metal

5. Continue dividing the groups according to their characteristics until leaving each element alone

6. Create a dichotomous key that includes the criteria used to divide the elements in the order used

b. It's head is not pointing ................................... It is a spoon

a. It's head is pointing ......................................... Go to Step 8

b. It's not used to warm up ............................... Go to Step 7

a. It's used to warm up ........................................ Go to Step 6

b. Not made of metal ........................................... Go to Step 5

a. Made of metal ................................................... Go to Step 4

b. They do work with electric power ............... Go to Step 3

a. They do not work with electric power ........ Go to Step 2

b. It has not a handle ............................................ It is a glass

a. It has a handle ................................................... It is a knife

b. It is not used to cut ........................................... It is a fork

a. It is used to cut .................................................. It is a knife

b. It's not used to cook ..................................... It is a microwave

a. It's used to cook ................................................ It is a oven

b. It's not used to drink ....................................... It is a dish

a. It's used to drink .............................................. Go to Step 9

7. Draw a phylogenetic tree that reflects the classifications made
