Today we practiced monohybrid crosses. We created marshmallow reebops by crossing two parents. We had to determine their genotypes and their phenotypes. Once we know the genotypes and phenotypes, we were able to create them with marshmallows.

Homework: crossword

Today was the 1st quarter exam.

No Homework!

I returned the meiosis quizzes today. Several were below what is acceptable so you had time to self correct them in class today. After the corrections were made, we moved onto Mendel and his genetics. We reviewed vocabulary and learned a few new terms. Material on the exam will be through the information we covered today. We spent a few minutes at the end of class reviewing cell structure and function(for the quarter exam) through a jeopardy game.

Homework: monohybrid cross worksheet 1-4

Today we practiced putting the phases of meiosis in order and then we took a quiz over meiosis. After the quiz, I handed out a study guide for the semester exam which is next Wednesday. Your homework assignment will help you prepare for the exam. We also began studying heredity and learning about some of the earliest studies Mendel conducted.

Homework: All On-line: *use the interactive tutor for Chapter 1 and Chapter 6
*take the Chapter 1 and Chapter 6 Tests and email results (over 85%)

Also: Using a Punnett square, determine the offspring of a cross between two second generation yellow pea plants: Yy x Yy (try to prove that 3 yellow will be produced and 1 green)

Today we reviewed meiosis. You took a "pointless quiz" over meiosis. Take the results from the pointless quiz and study tonight for a true quiz tomorrow!

Homework: prepare for meiosis quiz

Today we compared mitosis and meiosis by performing a lab exercise.

Homework: review meiosis

1st quarter Exam - next Wednesday 10/29

Today we learned about Meiosis - the process by which sex cells are made. A very important process which keeps the number of chromosomes consistent between parents and offspring. We watched a video which explained meiosis with the use of animation of the chromosomes.

Binders were collected

Next week will be the quarter exam! (either wed or thurs - we will decide tomorrow)

No homework!

Today we took the test over cellular reproduction. After the test, we saw a short video that explained more about stem cell research and the pros and cons of stem cell research.

Homework: stem cell response questions, binders

Today we reviewed for the test on Monday. We reviewed vocabulary by drawing pictures of the vocabulary words and also writing definitions of the terms. For a few minutes we attempted to play Pictionary with the vocabulary words.

Homework: Monday - Test Chapter 9
Tuesday - binders due

Today we went to the library and conducted a virtual lab which compared cancerous tissue to normal tissue.

Homework: finish virtual lab, cancer worksheet

Today we reviewed the cell cycle. We went over the activities at each phase. We also learned what controls the cell cycle and what happens when something goes wrong - cancer. We learned how valuable stem cells can be since they are undifferentiated and can become any type of cell under the right conditions.

Homework: Cell Cycle Flashcards - due Thursday!

Today we learned about the cell cycle: interphase, mitosis, cytokinesis

We learned what happens in each phase of the cell cycle.

We also learned that mitosis is broken down into phases: prophase, metaphase, anaphase, telophase. We learned about what happens in each phase of mitosis.

Homework: cell cycle review sheet

Today we reviewed the Chapter 8 test. After the test review, we took notes on cell size. For the last half of class, we conducted a small lab that showed how as cell size increases, the volume becomes larger than surface area - which is not good for cell transport and communication.

Homework: Read Chapter 9.1, Due Chapter 9.1 assessment questions 1-4.

Today we took the Chapter 8 test. After the test, we discussed why cells are so small.

No Homework!

Today we learned about fermentation - anaerobic respiration. When our cells don't have enough oxygen to go through cellular respiration, they go into a process called lactic acid fermentation. Only 2 ATP are formed per glucose molecule therefore, it is not a very efficient source of energy production. We spent the rest of class reviewing for the test tomorrow. Test Chapter 8 - Cellular Energy.

Homework: STUDY! Use the cut and match worksheet I gave you to study with.

Today we reviewed photosynthesis and cellular respiration. We discovered that the products of one reaction are the reactants of the other. They are almost opposite reactions. Photosynthesis makes food with solar energy, cellular respiration breaks down food for energy. We also finished the photosynthesis lab.

Homework: complete the cellular respiration summary sheet and the comparison table between photosynthesis and cellular respiration

Reminder: Test on Wednesday!!!!!!!!!!

Today we took the quiz over photosynthesis with the help of our photosynthesis booklet. We learned about cellular respiration and the three steps involved in respiration. We learned that for 1 glucose molecule we consume, about 36 ATP molecules of energy are produced for our bodies.

Homework: create a tri-fold booklet demonstrating the stages of cellular respiration.

Today we learned about photosynthesis in great detail. We learned that there are two phases to photosynthesis: the light and dark reactions. We identified what happens in each phase and what the inputs and outputs are in each phase. We also viewed a video about photosynthesis. After the video, we started creating a "book" which tells the story of photosynthesis.

Homework: finish Photosynthesis Book - may be used on quiz tomorrow!
