Agenda and Announcements
Big goal connection
2. Input – notes on prokaryotic and eukaryotic cells
3. Guided Practice – Cell ID team game
4. Independent Practice – Worksheet
5. Closing – Journal Reflection
Announcements
Binder Organization – Move all of
your notes from classwork into
study aids
YOU SHOULD HAVE NO
NOTES IN YOUR CLASSWORK
SECTION NOW
Objective
 After today, you will be able to identify
that scientists classify things based on
patterns, similarity, and diversity. You
will also be able to classify cells and
explain that a eukaryotic cell has a
nucleus and a prokaryotic cell does
not.
Big Goal Connection
 80% Mastery –
 Last 9 weeks we had 77.8% 71.7% 74.4% 52.8% on our
learning goals
 This 9 weeks we will make it to 80%
 Big Idea of Science – Patterns, Similarity, and Diversity
 You will be able to write a short answer response defining
this big idea and giving an example
 Organization – Well organized binders increase your
ability to find and study your notes. (It also means you
will earn your team more points on review questions)
Big Idea: Patterns, Similarity, and
Diversity
Scientists classify things
based on patterns,
similarity, and diversity.
In nature, some things
occur repeatedly creating a
pattern.
Big Idea: Patterns, Similarity, and
Diversity
Similarity means that
things are alike in some
way.
Diversity means that
things are different in
some way.
Let’s Practice…
What are patterns?
2. What does it mean if things
are similar?
3. What does it mean if thing
are diverse?
1.
Prokaryotic
Cells
Prokaryotic cells are very simple and
do not have a nucleus.
Instead of a nucleus, prokaryotic
cells have a nucleoid.
The only organelles that prokaryotic
cells have are ribosomes.
Let’s Practice…
1. Do prokaryotic cells have a
nucleus?
2. How are all prokaryotic cells
similar?
Eukaryotic Cells
Eukaryotic cells are more
complex and have a
nucleus.
They have a lot of
organelles including
ribosomes.
Let’s Practice…
1. Do eukaryotic cells have a
nucleus?
2. How are all eukaryotic cells
similar?
Let’s Practice…
1. What similarities are there
between prokaryotic and
eukaryotic cells?
2. Is there diversity among cells?
3. How are prokaryotic and
eukaryotic cells different?
GP1 – Which of these is a
prokaryotic cell? Why?
1
2
GP2 – Which of these is a
eukaryotic cell? Why?
1
2
GP3 – What do eukaryotic cells have
that prokaryotic cells do not have?
GP4
What do eukaryotic
and prokaryotic cells
both have?
GP5
ribosome nucleolus
Is this a prokaryotic
cell or eukaryotic
cell?
GP6
Is this a
prokaryotic
or
eukaryotic
cell?
GP7
You look through a microscope
and see a cell that has
chloroplast, a cell wall, a Golgi
apparatus, and a nucleus.
Should you classify this cell as
prokaryotic or eukaryotic?
GP8
How do scientist classify
things (refer to our big
ideas)?
3.1 Independent Practice
Journal
In your journal section,
write a reflection on what
you learned today, what was
interesting, and what you
though of class.
