Monday & Tuesday = Put it together days

A chance for you to demonstrate that you've finished your Big Picture Assignments (pp.95-100) and to finish up any notebook checks.

We'll also be working in groups to check our understandings of the Big Picture(s).

Finals schedule is Wednesday periods 1,2,3,4 and Thursday periods 6,7,8

Finish strong, remember to focus - and let's have a little fun while we're at it!

FRIDAY = QUIZ on Photosynthesis and Cellular Respiration

Question 11 is extra credit, just mark it next to #10 :-)

98, 99, 100 Big Pictures 4,5,6 - Ecosystems and Science

Why do we do science?  So we can investigate and explain the world around us - so we can LEARN!!!

Fasten 98, 99, 100 into your notebooks and finish them :-)

97 Big Picture Part 3 Cells, cell membranes, and Homeostasis

Fasten in p.97, review your notes, answer the questions, and start quizzing each other!!!

When you've mastered one of the Big Picture questions, have someone sign off that you're an expert.

Videos on transport (passive and active) - and another about active transport - and another about faciliated transport, there's a bunch online!

96 BIg Picture part 2 - Energy in Organisms

We're looking at the big picture of energy, and how cells use it for metabolism to make the changes (reactions) necessary to stay alive... Make sure you can explain:

• the role of ATP,
• how cellular respiration and photosynthesis are related,
• and where do chloroplasts and mitochondria fit into the picture.  
• the roles of Glucose, Oxygen, Carbon Dioxide, Water, and sunlight.

This video sums things up nicely, and was made by a student - why did he choose that song?

It's ridiculous how there are so many videos and sites about this; let us know if you find one that's really helpful!

For you above and beyonders...
Here's a really detailed video about cellular respiration - hang onto it for AP BIOLOGY

Bonus question - do you think chloroplasts and mitochondria have enzymes that make these reactions happen faster?

95 Big Picture Concepts, part 1

Fasten in the handout, grab your seat belts, and let's bring it all together.

How are organisms organized?
- Look at this and this and this and ...

What's so special about carbon?  (Why are we carbon based life-forms?)
- Robert Krulwich from NPR has a little video series

What are the most common elements in life? (CHON + PS)

What's so important about Enzymes? - they just control the world of chemistry (and life)!
- Looking at the energy of reactions, and how enzymes make things easier...
- How enzymes affect chemical reactions (5:26 is the best part about energy)
- A good video overview of enzymes - lots of details, and here's another video

Proteins - what are they made of?
- many enzymes are proteins, which are made of amino acids (what do ribosomes do?)
- DNA and the nucleus control which proteins are being made at any time, and since enzymes affect chemical reactions, the nucleus can determine which reactions should occur in the cell by making different ENZYMES (among other ways too...)

94 Cancer, a closer look

Today's learning goals are:
1.  Learn about the relationship between cancer and cell division (mitosis)
2.  Visually recognize the stages of cell division (PMAT vs I)
3.  Really master the characteristics of the stages of cell division (PMAT)

Keep these in mind as we explore the difference in cancer cells and normal tissue!

Fasten the handout to page 94 in your notebook
Complete the questions above the data table
Go to the virtual lab here
follow the instructions for the virtual lab and record your data in the data table.
Answer the question at the bottom of the data table.

Need help calculating percents?  Do it like this:
Cells in mitosis - first add up all the cells in p or m or a or t = P+M+A+T
Let's say that there is 1 cell out of 20 in mitosis.  1/20 * 100% = 5%
Now there should be 19 in interphase, so 19/20 * 100% = 95%
does 5% + 95% = 100%  --> yes, so we're probably doing it correctly :-)


When done, work on something else in your notebook, or go above and beyond by researching something that interests you about cancer.

93 Cells, an overview

Fasten the handout to your notebook, and then use the cards to:

1.  Explain the difference between Prokaryotic and Eukaryotic cells
2.  Explain similarities and differences between plant and animal cells
3.  Match organelles with their functions
4.  Match organelles with their appearance (in the cell pictures)

As usual, practice and then have someone quiz you!

New Notebooks for Next Semester

Time to start thinking about them - we have lots of these in class for a buck, or you can always get your own.  Make sure that the edges are bound (no spiral stuff)

92 Mitosis, PMAT, Interphase

After mastering this project you should be able to:

1. Put the steps of mitosis (PMAT) in order.
2. Tell the difference between a cell in mitosis and one in interphase
3. Recognize the visual characteristics of each step
4. Know what PMAT stands for

Fasten in the study guide, and then practice with the flash cards.

Have a partner quiz you on the four goals (above)!

90 & 91 How cells make copies of themselves --> Mitosis

By the end of this lesson you should:
1. Know what mitosis is
2. Be able to describe and recognize the steps of cell division
3. Put the steps of cell division in the correct order (PMAT)
Make sure you learn these things, or you have not completed this lesson.

Use the handout to guide your exploration:
