Q: Goldfish do not have teeth in their jaws. Their teeth are located in the back of their throat, which allows them to crush food and swallow food whole. If you listen closely enough, you may actually be able to hear a crunching noise from your goldfish's teeth as he chews on his food. Goldfish do not have stomachs. Instead, your goldfish's intestines do the digestive work that a stomach would normally do. In addition, the lack of a stomach means that your goldfish cannot eat much food at a time; the food that he can eat will move quickly through his digestive system.The lack of a stomach makes your goldfish more susceptible to digestive problems if he is not fed properly. Your goldfish's swim bladder is an internal gas-filled organ that allows him to stay buoyant in the water. If not fed the proper diet, your goldfish can develop problems with his swim bladder, which means that he would not be able to easily stay afloat in the water.
A: Identify the location of your goldfish's teeth. Learn about your goldfish's digestive system. Learn about the purpose of your goldfish's swim bladder.

Q: Sticking to a set structure and keeping track of time will help you maintain an orderly debate. From classical debate to public forum structure, there are a variety of available formats. A modified classical debate format is usually the best choice when teaching debate to beginners. The 2 sides take turns making timed statements and rebuttals, then each makes a closing statement. In classical debate, openings statements last 6 minutes. If you want to lighten students' loads or if time constraints are an issue, set opening statements at 2 to 3 minutes. The side in favor goes first, then the side opposed makes a rebuttal, which you could set at 1 minute. The side opposed then makes its opening statement, and the side in favor issues their rebuttal. After opening statements and first rebuttals, each team makes timed statements that support their claim and refute the opposing argument. In classical debate, each side has 4 to 6 minutes per statement or rebuttal. If you need to squeeze multiple debates in a single class period, give students 2 to 3 minutes to make each statement. If time allows, give students 30 seconds to a minute in between statements to organize rebuttals to the other team's argument. The side in favor summarizes their argument in a closing statement first. Then the side opposed issues their closing statement. If time allows, give each team 30 seconds to a minute to make adjustments before making their closing statements. After the debate, assign a winner (if you think it's appropriate) and discuss it as a group. Ask students to reflect on the concept of formal debate and the importance of making a clear, well-reasoned, and well-supported argument. For homework, have them write a brief reflection or fill out an evaluation handout. Handout questions could include, "What are some qualities that make a debater effective? How could any of the teams have improved their arguments? How important is it to stick to a debate format's rules?"
A: Select a debate format and explain it to the students. Have teams present timed opening statements and rebuttals. Allow students to take turns presenting and rebutting evidence. Have each side present closing statements. Instruct the students to evaluate the debate.

Q: Drag your finger across the front of the fish tank or bowl. If she moves towards it, reward her quickly with a treat. If she does not notice you, shake your finger until she notices. Move your finger in multiple directions. First, move your finger to opposite sides of the tank. Next, move your finger vertically up and down. Reward your fish each time she follows you. Train her for three to five minutes at a time over several days. Proceed to other tricks once she consistently follows your finger. Once your betta can follow your finger, teaching other tricks will be easier. When a male betta sees another male in nature, he flares. Flaring consists of a betta stretching her fins and opening her gills as much as she can. Bettas then look twice their size. You can teach your male or female fish to do this pretty trick. Flaring provides exercise, prevents boredom, and promotes bubble nest building. Bubble nest building consists of male bettas methodically blowing small bubbles in clusters on the water's surface. Only perform the flare trick three to five minutes a day or you can overexert your betta. Follow these steps: Gather a small mirror and a red or black-capped pen. Use the same colored pen throughout training so your betta will recognize the pen. Place the mirror in front of the tank. Once your betta flares, place the pen next to the mirror. Repeat this process two to three more times. Sometimes your betta will get afraid, and may move away. Keep on trying. Once your betta instantly starts to flare, remove the mirror and leave only the pen. Give your betta food or a treat each time she flares. Continue until your betta flares each time you show the pen. Jumping is a natural habit for betta fish. To train your betta, use a feeding stick and place half a bloodworm on it. The food should be within reach of the fish. Starting with the stick underwater, have your betta come to you. With the next try, move the feeding stick closer to the water's surface. Have your betta swim to you. Then move the stick to the water's surface. Your betta should swim to you. Lastly, move your stick slightly above the water surface. Once your betta recognizes that she can get food from the stick, she will jump for it even if the stick is out of the water. After she nails the trick, you can substitute your fingers for the stick. By halving your bloodworms, you can avoid over-feeding your betta. Remember, she should have a maximum of three to four bloodworms in one sitting. You can train your betta to recognize a feeding stick, a thin stick with a curved end for attaching food, during her normal feeding times. Bettas naturally jump when excited or scared. Purchase a lid for your fish tank to prevent your betta from jumping from the tank. She can still jump when you remove the lid to feed her. Gather a pipe cleaner. Bend the pipe cleaner into a circle with a two inch diameter. Hang it on the side of the fish tank. The hoop should be perpendicular to the side of the aquarium and touching it. Move your finger along the outside of the tank in one direction through the hoop. Each time she swims through the hoop, give her a treat. Repeat this process until she regularly swims through the hoop. Gradually decrease the hoop size until it is slightly larger than one inch in diameter. After she is comfortable with the trick, move the hoop farther away from the tank's sides. Continue until she can swim through the hoop while you hold it in the center of the tank. This is one of the most difficult tricks so do not be discouraged if it takes a while. Be sure that your pipe cleaner is brand new and does not contain toxins that could harm your fish. Your betta will eventually figure out that if she does what you ask, you will reward her. Do a training session once per day. Be persistent. Do not overwork your betta, though. Make sure she has sufficient time to rest and relax. Do not force your fish to play if it doesn't want to. They don't exist just for entertainment.
A:
Teach your fish to follow your finger. Train your betta to flare on command. Teach your betta to jump. Train your betta to swim through a hoop. Keep trying!
