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.

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.

Answer Worksheet #1 individually, then discuss your answer as a group.

Mr. Ignacio

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.

Criteria

WORKSHEET #1Name:________________________________________ Year & Section: _______

_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

My specimen of choice is…

___ Baby pig

___ Cat

Others:

1. What specimen did you and your team choose? What criteria did you pick to justify your choice?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

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 results

and go back to your original

team. Then answer the

remaining boxes below.

3. Which 3 criteria are common among all teams?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Team 6

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.

Phase 2

Work on

Worksheet #3

as a group.

Which goes first? second?...arrange the procedures on the left box by writing the LETTER chronologically on the right box entitled

“What I know”.

A. Clean up the kitchen area and wash your hands.

B. Dispose removed parts properly in trash bins.C. Lift and cut through the muscles and breast

bone to open up the body cavity.D. Locate and identify the organs.E. Place the animal on a cutting board.F. Put on an apron.G. Turn back the cut skin away from the body

area.H. Turn the animal on its back and firmly lay it flat

on the cutting board.I. Use your finger and knife to lift and remove

organs.J. Use your finger to lift the skin and use knife to

cut along the center of the body.

completely? If “YES” then good job on your effort!

If not, it is really advisable that you complete them first before proceeding to your

next task.

To find out if your answers in worksheet #1 are correct click and read this website.

After you have read this website, answer Worksheet #4.

After you have read website 1, answer the questions below. 1. What facts or ideas point out that the frog is the best specimen for our dissection activity?______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________2.

Website 5: Practice Test 2http://www.biologycorner.com/frog/frogtest4.html

Try answering Practice Tests 1 and 2. Count your correct answers and verify which item you got wrong to 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 half of the items you need to answer.

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? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ __________________________________________

After you have performed your virtual frog dissection, I hope you’ve gain some experience prior to the real dissection.

Now, check how much you have really learned by answering Worksheet # 6 individually. Then compare your answers with your team.

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.htm

to relearn the concepts.

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.

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.

Express what you think of the recently concluded

activity by writing a letter to Mr. Ignacio. Use the questions below as your guide and creatively design your paper.

Introductory…• What is your opinion regarding dissection of animals in the laboratory?Body of your letter…• Are you for dissection or not?• If you are pro-dissection, would you recommend it to the next biology students?• If you are anti-dissection, what would be a better alternative to using animals when

studying anatomy?End your letter with this…• What could be a short term goal of this lesson for you?• What could be a long term goal of this lesson for you?
