Inheritance and Traits:

Lesson 1.6: Making Sense of Variation

Open Ended

DO NOW: What did notice about the traits in your class? Was there a lot of variation? How do you know ?

Activity 1

Reading: Handbook of Traits

Remember that we are investigating this question: 

• How can we describe the traits of organisms in a species?

• We are going to talk about how species with the same traits can have variations.

• Last class we collected data on variation in this class

Handbook of Traits

Let’s read about other organisms to get more evidence for this idea.

Evidence is information that supports an answer to a question. 

Turn to page 16 in your notebooks

• You will read about an organism and record how its traits can vary.

• Let’s try an example together.

Evidence About Trait Variation

• When I read the page about variation, I see that dolphins can vary in size, color, beak size, fin size, and whistles.

• I can record this in my notebook.

Handbook of Trait (read pages)

• page 12-13

• page 20-12

• page 28-29

What is some evidence you gathered to support the idea that traits can vary within a species?

Activity 2

Modeling Trait Variation

Use a digital app to create our models. Step 1

• First, you will click on CHOOSE A TRAIT and pick a trait from the menu.

Step 2

• Select cats that show variation for the trait you chose and drag them into the column.

   

• For example, for fur color I would choose cats with different colors of fur.
