  1. You need to pin the frog down first.Then you need to use the scalpel to cut open the frogs skin.Next you need to lean your scissors any way will be alright.Then you cut the middle then next to shoulders and legs.You have to lean the scissors so you don’t cut the organs.Now you can use a curved or a regular easing needle to observe the frog.

    • you need to pin down the you e frog then you take the scalpel. then you cut the frogs skin then you look at all of the things inside when you are done looking at the frogs skin you cut the fatty skin with the scissors you look at the stomach and the other body parts when you are done you tell the teacher. :):):):):)

  2. 1. When you dissect a frog you use a scalpel to open it, but you have to be careful not to touch the organs.

    2. You are looking for the eggs on the frog.

  3. 1. The first thing you would do in dissecting a frog is pin the frog to the dissecting tray, then you make three cuts in the abdomen and be careful not to press to hard because you will cut the organs, and once you do that you must pin the skin down.

    2.when dissecting the frog you will be trying to find out if it is a girl or boy.

  4. First you pin the arms down.Then you use the scalpel to cut the skin. Then you pin it down. Cut the remaining tissue so you can see the organs. Take out the fat body. Identify the frog organs. The n you clean up and your ready to end.

  5. First you tear open the skin then you pin it back. Then you take out the fat bodies and identifie organs and if male or female. Final clean up.

  6. first you would pin the frogs limbs down. Then, you would make an incision on the frogs abdomen. Use a scalpel and or scissors to cut. Don’t press to hard because if you cut through the skin and into the organs it will mess up the whole dissection. Cut a line down the belly of the frog and two cuts on top and bottom then pull back the skin and pin the skin to your dissection tray. Then make three horizontally cut across the body. Then take out the stomach and small intestines to see if it is a female or male see if the frog has eggs then it is a female and if it has testes it is a male. I hope this helps you dissect your own frog!

  7. 1. First you have to cut the skin open with a scalpe.Then you have to pin the skin back with the tipins. After that you that you take the fat bodys out. Then you look at the organs and discribe the organs too. After do what your teacher tells you to do then you are good to go.

    2. I am looking forward to look at the organs in the frog,and I am also looking forward to just to dissect the frog. Ithink it will be very interesting. 🙂

  8. To dissect a frog you need to wear gloves.You need a scalpel scissors ,teasing neadles ,forceps ,t-pns and a dissection tray.First pin the frog to the dissection tray. When cutting with scalpel, cut away from your self.Make three cuts to skin and to the tissue.Pin the the flaps of skin to the dissection tray. Then identify the organs.Finally clean up.

  9. I bet it will be super gross! I never ever, like ever going to dissect a frog. Just never because it’s gross and you can see all the organs. If I were ever dissect a frog, you have to wear gloves and goggles, a lab coat and a pair of shoes that can cover your toes (you have to so you can’t lose a toe).

    I’m never dissecting a frog. Ever!

  10. The first step is to pin the frog legs to the table. Then you cut the first layer of skin 3 times with the scalpel. Then you cut the second layer
    of skin with scissors. Then you take out the fat bodies. Finally you identify the organs and see if it is a male or female. Share what you see.

  11. The first step to dissecting a frog would be to pin down the feet and hands.Next you would get the scalpel and make 3 cuts.Then you would get the scissors and cut 3 cuts in the tissue under the skin.After that your would remove the fat bodies.Last you would look though the organs and see if it is a male or a female.That is the 5 steps to dissecting a frog.

  12. First you need all your tools. You need a scalpel; scissors; teasing needle; curved teasing needle; tweezers; pipet/eye dropper; t-pins; ruler; dissection tray. First what you do is lay your frog down and pin it down with the t-pins. Then you get your scalpel and cut the skin it is very important that you cut away from yourself. After that you get your scissors and cut the second layer. Then you can have fun and dissect your frog. Make sure you have tennis shoes were jeans; goggles; a lab coat; and girls wear your hair back.

  13. first off you need your dissecting tools: Scalpel, Scissors, Teasing Needle, Curved Teasing Needle, Torceps or just Tweezers, Pipet (eye dropper), Pins, Ruler, Dissection Tray. you pin the frogs legs (and arms) to the dissection tray with the pins, you cut the skin with the scalpel or the scissors away from your body, you cut 3 lines on the skin and then pin it. then you just go through the organs to find if it is a female or a male. if it is a female it has black eggs.

  14. Steps of dissecting a frog:
    1.) Pin specimen on dissection tray.
    2.) Take scalpel and make 3 light incisions in outer layer of skin.
    3.) Then take scissors and cut muscle tissue, making sure not to damage any organs in the process.
    4.) Now you will see the organs of the frog.Take out fat bodies and identify organs.To help with this you will need tools such as teasing needle,curved teasing needle,and forceps.
    5.) You may also identify if your specimen is male or female.
    6.) Now clean up any remains and put away tools!

  15. If you want to dissect a frog, first you need all of the tools. You need the
    scalpel, scissors, teasing needle, the curve teasing needle, forceps, pipet,
    t-pins, ruler, and finally the dissection tray. Now you have to cut the skin from bottom to top with the scalpel. Then you have to cut the top and bottom part of the incision, left to right, on the frog. Now you have to pin the flaps down. Next you have to cut out the fat bodies. Now you are inside the frog. Now cut out all the organs.

  16. 1. First thing to do is get a lab coat, goggles, tie hair back(girls), get a scalpel, scissors, and pins. Get the scalpel and open three slits away from you one up, two to the sides one on the top one on the bottom.
    2. I’m not participating in this activity.

  17. You would take a scalpel and cut the frogs body away from you(Start from the bottom of the body and up).
    I would not push to hard on the body because, you can ruin the organs and then there might be a bloody situation.You should be careful about cutting the organs and how you would cut the skin.
    I am ready for the guts and dissection.

  18. For a frog dissection you first need to pin your frog down.Then you need to use a sclpule to cut thee light cuts.You then need to take out the fat bodies.After that you need to identify the organs.When your done with that you need to clean your dissection space.

  19. The first thing you should do is get your gloves on along with your goggles! Next, get your apron on and hair pulled back (girls). Now comes the gross part, cutting open the frog! Pin your frogs arms and legs down and grab your scalpel and make three slits in the frog (first layer of skin only)!!! Then, pin that layer of skin back. After that, you can carefully cut the next layer of skin with the scissors, not the scalpel. Now you can observe the inside of the frog! Try to label all the parts of the frog in your head. To sum it all up, HAVE FUN!!!!

  20. I cant wait until i do the frog dissection. First you have to pin down the skin on the arms. cut with scalpel only three times softly. Pull back and pin skin, cut the tissue organs again and pin the tissue. You should have six pins pined down. Use the tweezers and flip organs around and figure out if male or female. Blue eggs means girl. All clear then a boy.

  21. 1 you take the pins and you pin the arms and legs down the you take the scalple and make three slits in the frog be careful you don’t cut the organs then you can explore the frog body.

  22. Wow.I can’t wait for the frog dissection.First,you cut open the skin,then pin the skin to the dissection tray.second,cut open the muscles and pin the muscles to the tray.

  23. First you have to cut the frog open. Then you pin the frog down. Then you cut the second layer. Then you pin the second layer down. Then you need to be careful when you pick up the organs.

  24. first you pin the frog.then you need to cut the frog. then you can you cut the fat off. then you can look at the organ and named them and see if it a female or a male

  25. 1 you have to cut the frog open. Then you have to open the skin and pin it down. Then you need to be careful when you pick up the organs. That is all the steps.

  26. There are many steps you need to take to dissect a frog. First you pin the frog’s legs and arms down. Secondly you get the scalpel and cut away from your body (up). Then you would use the scalpel to cut at the top of the first cut and at the bottom. Next you would pull the flaps away from your frog and pin them down too. Then you would use your scissors to cut the frog open even more. And then you pin the flaps from that down and explore your frog’s organs!

  27. Here’s the steps to dissect a frog.
    1.Pin the frog so it wont move
    2.Next you take your scalpel and cut away from your body so you wont get cut
    3.Pin the skin to the tray so it wont dangle and so it wont bother you

When you dissect a frog you must have gloves on second step you must pin the specimen then you get your scalple and cut the skin of of it then you pin the skin after that you get the scissors and cut through the second layer after that you should be able to see the heart and the rest of the organs in it

  32. First you would pin down the frog. After your done pinning you use the scalpel and cut away from your BODY! After you do that pin the skin down so they don’t flap at you when you look at the muscle tissue. Then you cut the muscle tissue away from your BODY and pin down the muscle tissue. Then you look at the organs. Tools you should use goggles,sandals,roll up your long hair,and ALWAYS were GLOVES! That is what you use to dissect a frog.

  35. Dissecting a frog sounds really cool! My class recently got an elk heart donated to them for science. We put on gloves and got to feel the heart. We felt the inside of the heart valves. The elk heart smelt like dead fish! I hope next year we get to dissect a frog!:D

  36. Hi i’m Brooke i’m from Mr.Lockwoods class.My class recently touched an elk heart we were going to dissect it but it got to spoiled.I really want to dissect something it looks cool.Some people think it is gross but i think it looks fun.I hope I get to dissect something next year!

    Thats how you dissect a frog.

  38. First I would use a pin to pull it down. Then i will use a scalpel/scissors to cut it up. Then i will move the other layer of the frog skin.Then you could see the organs.

  39. First you pin arms and legs down. Then you use the scalpel to cut 3 times 1 by the neck 2 down mid section and 3 in lower section. After that you peel skin back and pin the skin down. Cut 3 times again open and pin. Then you can see all the internal organs. Last but not least you will clean up and your done.

    !!!!!!!!!!!!!!!! AWESOME!!!!!!!!!!!!!

  40. First of all you have to put the frog in the tray, Then pin the frogs limbs down with pins, Then you cut down the frogs stomach with the scalpel, Then on both ends of the cut only sideways, Then open the flaps and pin them down, Then start cutting down the frogs stomach again while cutting 3 lines intercepting the cut sideways, Then open the flaps and pin them down again, Then your ready for dissection and examining the organs 😀

  41. Well first, you pin down the frog (so it dosnt move ).Then you cut the first couple layers with a scalpel.Then you cut it again with the scissors.Then you cut of the fat of the frog (GROSSSSSSS).Then finally you have to identify if its a male or female.
