Big Idea #4

Determining

the Age of a

Star

Steps and

Results of

Nuclear Fusion

Stages of

the Star’s life

cycle

How different

elements are

produced

Let’s Review!

Today’s Success Criteria

B3: Describe the connection between the type of stars and

the elements it can produce

Refresher:

B1: Describe how lighter elements form other light elements [Hydrogen (1) Helium (2)]

B2: Describe how heavier elements are produced in stars [Lithium (3) Iron (26)]

Big Question: What’s keeping us alive?!

Elements are an important part

of our lives:

Hydrogen+ Oxygen= water

Nitrogen= proteins (muscles)

Carbon= Carbohydrates (food)

and lipids (fat)

Big Idea #4: Where are elements made

What elements were formed in

the big bang?

Go to your periodic table and

color them in with a yellow

marker/highlighter.

Look at the Table. Based on last

block, where do you think the

other elements came from?

Let’s Review Nuclear Fusion

Formation of Heavier Elements

1. Look at Helium.

2. The number above is the atomic

number. When two Helium combine in

nuclear fusion, we add the numbers

together.

3. Look at your periodic table. What

number would we get when 2 Helium

combine during nuclear fusion?

Formation of Heavier Elements

Let’s practice!

Work with a partner to use your elements to create 8 new elements.

Check in with teacher to see if you are correct.

C + C = ?

C + C = ?

6 + 6 + 12

C + C = Mg

Big Question: Where do the elements

come from?

What elements were

formed in each star

stage?

Go to your learning

target practice sheet.

Color main sequence in

green.

Color red giant in red.

Color Super nova in blue.

Show off your knowledge!

Record and Represent

1. Complete the box “How elements form (Element “math”) on your Learning Target Practice Sheet.

2. Shade in how you feel about success criteria B3

How elements form [Element “math”]:

What elements would have to come together to create the following:

_____________ + ________________ = Helium (2)

______________ + ________________ = Beryllium (4)

______________ + ________________ = Iron (26)
