Open Ended

DO NOW: Look at pages 32-33 in your notebook. Describe a pattern of traits between parents and offspring that you read about organisms in Handbook of Traits.

Activity 1

Setting Purpose for Reading

Look closely at just the offspring in the fruit fly family.

What do you observe about the fruit fly offspring?

Today we will investigate this question:

Why do offspring have similar traits to their parents but not always to each other?

The Code

We’ll begin to investigate our question by reading a book called The Code.

Turn to page 37 in your notebook.

As you read, you can use Column 1 on the notebook page to record your questions.

Column 2

Record the information and page number where you find the answer.

Column 3

Think of other ways might investigate the question and record your ideas in column 3.

Before you start here's an example

Listen to page 5

Um,

I read on these pages that we can inherit, or receive, traits from our birth parents. These are called inherited traits, and they are passed down through the code. However, I’m still not sure how does code pass down traits?

I wonder..

...how does the code pass down traits?

Let’s record our question on the notebook page.

Lets keep reading

page 8.

We read....

Genes are the instructions for how to make our bodies. All our inherited traits come from the genes in our code. This information helps answer our question about how the code passes down inherited traits.

Column 2

Column 3

What are other ways could we investigate this question?

Now it your turn.

• Make sure your to include the page number where you found your information so you can find it again.

• we will stop every two page for 3mins
