Every reading assignment is expected to be completed BEFORE you come to class. Confused about the
reading? Prepare questions to ask in class AS YOU READ.
Be a Scout and Be Prepared…Reading quizzes may be given at ANY time.
Homework is due ON THE DUE DATE (Sectionals—Turn in on the due date…Field trips and
illnesses—turn in on your first day back.).
Do Now’s are to be completed in class and turned in THAT BLOCK. (Absent??—Turn in first day
back. Questions on the reading that goes with the Do Now??—Turn in written question specifying
what you don’t understand. Be specific. Don’t say, “I don’t get it”.)
Vocabulary understanding is necessary. Attend to the words at the beginning of each chapter, or words
that you encounter that are new to you.
6. **In order for you to participate in structured activities and labs, you must have
your Guided Reading up-to-date as well as your vocabulary.

VOCABULARY
1. Binary Fission-A simple copying of DNA in the cytoplasm, then division of the
entire cell, each with one copy of the DNA. Occurs in Prokaryotes.
2. Cell Cycle-The series of events that take place in a cell leading to its division and
duplication. The main phases of the cell cycle are interphase, nuclear division, and
cytokinesis.
3. Crossing-Over-In Prophase, an arm from an homologous pair may lay across its
sister chromatid. This may result in a fragment from each breaking off and
switching places with each other. Leads to more variation in offspring.
4. Cytokinesis-The final phase of a cell cycle resulting in the division of the
cytoplasm.
5. Endosymbiosis-A theorized process in which early eukaryotic cells were formed
from simpler prokaryotes.
6. Gamete-A specialized cell (egg or sperm) used in sexual reproduction containing
half the normal number of chromosomes of a somatic cell.
7. Interphase-The longest-lasting phase of the cell cycle in which a cell performs the
majority of its functions, such as directing protein making, preparing for nuclear
division and cytokinesis.
8. Metaphase-Phase in which chromosomes line up in the middle (equator).
9. Meiosis-A two-phase nuclear division that results in the eventual production of
gametes with half the normal number of chromosomes.
10. Mitosis-A nuclear division resulting in the production of two somatic cells
having the same genetic complement as the original cell.
11. Zygote-A fertilized egg.
Cell Cycle and Cell Division Game-Making
Directions:
1. You and your lab partners will make a game that utilizes the vocabulary
words, content of the Guided Reading, videos, Play-doh and other activities
for one particular process. The processes are those that you color-coded for
your vocabulary words.
2. Read the Self-Evaluation Grading Rubric for the game to be sure you
understand the Domains for which each person will be graded (24 points).
In the ‘Evidence’ column of the grading rubric:
a. Write your: two vocab word questions, sketch the model, write the
reference, what part of the game board you made, answers to your
two vocab and one model question, the game directions you suggested
that were used.
3. Read the Game Evaluation From the Players to understand how your game
will be evaluated by your peers.
4. Read the Teacher Evaluation form to understand how I will be evaluating
your group contribution (10 points).
5. In your group, decide what kind of game you are going to play and tell me.
Once that kind of game is ‘taken’, it cannot be used again in this class.
6. Each partner is responsible for contributing to all but the last domain. Keep
track of what you do on your grading rubric as you do it.
7. Use materials that are on the supply table, or ask me for additional goodies.
8. You have two days to plan, create, and do a dry run of your game.
9. On the third day, you will leave your game on a lab bench and rotate to a
different lab bench to play the game that is there.
10. You will complete a Game Evaluation From Peer Players on the game you
play that was made by others in your class.
11. Your total score will be a combination of your self-evaluation, my evaluation,
and the average of the peer evaluations (10 total points for the peer
evaluation).
Group ‘Job’ Descriptions
Facilitator- Every group needs a coordinator who will support others in getting
their tasks accomplished. The facilitator may be the ‘go to’ person for content
material as well. The facilitator takes responsibility to ask the teacher for help on
behalf of the team.
Graphic Design-Person with ability/interest in doing a layout for the game board.
Takes suggestions of other team members into account.
Software Expert-Person who oversees computer word program input of questions,
answers, answer key, labeling, model paste/cut, etc.
Timekeeper- Person who keeps group members moving along, cleaning up before
the end of the block. Responsible for encouraging team to complete task on time.

Not necessarily the Mona Lisa, but attractively

Not happy? Talk to your team about your solution
without attacking anyone personally. Plays well with
others.
Wahoo! Every group needs a coordinator who will
support others in getting their tasks accomplished.
The facilitator may be the ‘go to’ person for content
material as well. The facilitator takes responsibility
to ask the teacher for help on behalf of the team.
