1. A nut to me! Biology Name: _______________________ Group #: _____________________ Year and Section: ______________ Teacher: Mr. Noel Que A Learner-Centered Learning Environment Module on Anatomy

2. Phase 1 One day in your biology class, your teacher, Mr. Ignacio, told the class to brainstorm and identify a live animal that you can bring into the lab. Your group mates thought of 5 different kinds of animals; a cat, a chicken, a frog, a mouse, and a baby pig. Guys we need only one animal… Give 3 reasons why you think that animal of yours is the best one for our dissection activity this coming week. Answer Worksheet #1 individually, then discuss your answer as a group. Mr. Ignacio

3. Decide which specimen you would choose and state 3 reasons why you would choose this animal. Check 1 specimen on the left and give 3 criteria on the right. WORKSHEET #1Name:________________________________________ Year & Section: _______ Criteria My specimen of choice is… ___ Baby pig ___ Cat ___ Chicken ___ Frog ___ Mouse Others: _______________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

4. WORKSHEET #2Name:________________________________________ Year & Section: _______ Now that you’ve answered the first box, go around with the other group and ask what they have chosen and what their criteria are. Tally the resultsand go back to your original team. Then answer the remaining boxes below. • What specimen did you and your team choose? What criteria did you pick to justify your choice? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 3. Which 3 criteria are common among all teams? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

5. Phase 2 Your class was able to come up with the best specimen for the forthcoming lab activity. Mr. Ignacio poses another question to the class, “Do you know how to remove the innards of some animals when cooking food?” To find out who knows how to do it, Mr. Ignacio challenges the class to arrange the steps in dissecting the specimen while ensuring its internal parts would not be damaged. Work on Worksheet #3 as a group.

6. Clean up the kitchen area and wash your hands. Dispose removed parts properly in trash bins. Lift and cut through the muscles and breast bone to open up the body cavity. Locate and identify the organs. Place the animal on a cutting board. Put on an apron. Turn back the cut skin away from the body area. Turn the animal on its back and firmly lay it flat on the cutting board. Use your finger and knife to lift and remove organs. Use your finger to lift the skin and use knife to cut along the center of the body. What I learned 1st _____ 2nd _____ 3rd _____ 5th _____ 6th _____ 7th _____ 8th _____ 9th _____ 10th _____ Which goes first? second?...arrange the procedures on the left box by writing the LETTER chronologically on the right box entitled “What I know”.

11. Try answering Practice Tests 1 and 2. Count your correct answers and verify which item you got wrongto find out how you fared and how well prepared you are for the next thing to be done. Remember, be honest! You can only proceed to the next task if you scored at least halfof the items you need to answer. Website 4: Practice Test 1 http://www.biologycorner.com/frog/frogtest1.html Website 5: Practice Test 2 http://www.biologycorner.com/frog/frogtest4.html

12. Think about this... Did you score well in the first 2 practice tests? __________________________________________ What is your combined score? ____________________________________________________________________________________ Which particular item/s did you answer incorrectly? ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ What should you do to relearn the items you got wrong? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ __________________________________________

13. After you have performed your virtual frog dissection, I hope you’ve gain some experience prior to the real dissection. If you got half or more than that, do this froggy dance because you are ready to proceed to the next task. If you didn’t get half, I advise you to go back to http://www.ofsd.k12.wi.us/science/internal.htmto relearn the concepts. Now, check how much you have really learned by answering Worksheet # 6individually. Then compare your answers with your team.

14. WORKSHEET #6Name: _________________________________________Year & Section: _______ For this task, pay particular attention to the internal organs found in both frogs and humans. Label as many as you can on both illustrations individually (use pencil). Then come together as a group to compare your work.

15. WORKSHEET #7Name: ________________________________________Year & Section: _______ Work as a team in this Venn diagram. Classify the features or parts by listing inside the circle with the heading “FROG” those which are found in frogs only. List down inside the circle with the heading “HUMAN” those which are found in humans only. Finally, list at the center, where the two circles overlap, those which are found in both humans and frogs. FROG HUMAN BOTH

16. Areyou now ready to dissect a frog? Prepare all materials needed as stated in your lab manual. (p.45) and see you in the lab!!!

17. Performance Reflections ... • Read the Rubrics on the next slide. • Choose a partner for peer-evaluation. • Rate your peer by choosing which of the categories (vertical column) you think best describes how he/she performed during your lab activity based on each criterion (horizontal column). • Write your rating of his/her performance on the right side column under Peer-Rating. • Be reminded that your teacher had rated you during your lab activity and the rating you would give to your peer will be compared to his.
