Homework: None Do Now:
Set up today’s notebook entry with the title and date in the proper format!
What are the benefits of having a class environment in which students are quiet and respectful? Write down at least two.
Describe a class you’ve been in that is quiet and respectful. What helped to make it that way?
Today’s Objectives:1. Re-set our classroom norms so that we can have more productive
classes!2. Identify 3 components that ALL cells have3. Explain why cells are important to all living things4. Explain where the heck cells come from5. Maintain a neat and organized scientific notebook
Scientific Notebook Guidelines Observing Cells Notes/HW Review: What are Cells? Ticket To Go
Today’s Agenda:
Scientific Notebook Guidelines
Each entry should have… Date (outside corner, under page #) Title Do Now (clearly labeled) Notes – accurate, complete, detailed, w/ labeled diagrams! Neatness
Other Guidelines: Only Bio! Never tear out a page! Use your 2-pocket folder! Key handouts stapled in! Keep it nice!
You get graded on all this!Class Objectives: 1. Maintain a neat and complete scientific notebook
Taking Notes in Class: Class Norms
Purpose: Review and add details to the notes you took from the
reading Take notes on new information Discuss and ask questions about the day’s topic Draw diagrams so you can picture what we’re learning
How it works: “Cold calling”
What if you don’t know? During Note-Taking, you should be:
Listening and ready to answer a question Quietly writing down notes and drawing diagrams from the
board UNLESS they’re a repeat of your HW Asking questions about things you don’t understand or
things you want to know more about!
Do Now #2: Silently write down 3 observations about this picture
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
This is the first image anyone ever saw of cells!
Do Now #3: Write down ONE SIMILARITY among all of these pictures:
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
What makes a cell?
3 things ALL cells have:• Cell membrane (barrier)
• DNA (genetic info)
• Cytoplasm (fluid)
Class Objectives: 1. Identify 3components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from

Important Ideas About Cells: (aka- the Cell Theory)
1. All living things are made of cells.
• Multicellular Organisms (many cells)
• Unicellular Organisms (one-celled)
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
Class Objectives: 1. Identify 3 components that ALL cells have2. Explain why cells are important to All living things3. Explain where the heck cells come from
2. Cells give an organism its structure and function - they control everything the organism need to do to stay alive
Even the most complex organisms are made of
a bunch of different types of cells working together.

Proteins – Large molecules that do many important jobs in
living things, such as: Form body structures (muscle, bone, hair, eyes,
nails, skin) Act as enzymes to speed up chemical reactions
(like digestion) in our bodies Act as hormones that send signals through the
bloodstream Help your immune system (keep you from getting
sick)

Bio 9D: Friday, 10/1/10Title: Cells Under the Microscope Lab
Homework: Due Monday: Detailed paragraph (must be typed) on a Day in the Life of a Cell
Describe how the organelles in a cell work together to make and use. Include at least 5 different organelles in your essay.
Silent Do Now: (in notebook w/ title and date) Describe one safety rule that you think is
important for this lab. Why do you think this is important? If you have time, describe and explain the
importance of other lab safety rules. You should be writing for the entire Do Now time.
Objectives for Class:1. Follow proper lab safety rules and procedures.2. Identify the visible organelles in a Eukaryotic Cell3. Use microscope adjustments to focus the microscope and
bring images into view
Lab Safety Rules Use water droppers and iodine to
make a proper wet-mount slide Look at cheek cells and Elodea
plant cells under the microscope Be patient – seeing this stuff can
be difficult! Look carefully and persevere.
Use forceps and scissors to manipulate specimens on the slides
Work quietly and productively w/ your assigned partner
Clean up by rinsing slides as the sink by your lab table
Put Elodea leaves in the trash when cleaning up
Put notebooks away, put bags under your chairs. Take only the lab packet and a pen/pencil back to your lab station.
Don’t squirt water or iodine anywhere other than on the slide
Don’t put anything else on microscope slides (pen ink has ruined some slides!)
Don’t stick/cut anything else with forceps or scissors
Don’t move to other tables or talk across the room
Don’t move across the room to clean up or get materials. If you need something, raise your hand!
Don’t rinse leaves down the drain!
Take anything other than the lab packet and a pen/pencil to your lab table.
DO’s DON’Ts
Cells Under the Microscope Lab
Listen silently to your teacher’s instructions (remember: time wasted is time you don’t get to work on the lab)
Send one person to get materials
Follow each step of the lab (read it out loud)
