A game to disscetion

Follow along with our Dissection Activity. Make sure to hover your cursor over all parts of the beetle so you don't miss anything. You can also "glue" the beetle back together to take a step back and explore a new area. Make sure to explore the x-ray view as well to get another look at what's inside of the beetle. Follow along on the dissection worksheet to make sure you haven't missed any areas you can explore.

As you poke around, think about why certain body parts may be structured the way they are or located where they are. Once you've completed the dissection, you should try out the x-ray beetle navigator page to get a feel for how scientists analyze insect anatomy with MicroCT technology. As you explore all the tools and activities the Beetle Dissection has to offer, don't forget that all of this relates to real live insects.

Perhaps if you go outside near your home town, you may find scarab beetles similar to the ones you see here. After completing these activities, just think how much more you will understand about how these beetles fly, breathe, and live. Jon Harrison, Meghan Duell. Dissection Activities. Beetle Dissection. I was not told very much. They are amazing doctors and the staff is the best I have ever seen.

Doctor Claude Beauchier of the Kapuskasing Hospital foun the problem. Introduction: Heart Dissection. More by the author:. About: Hi there! Hopefully these guides can help inspire you to tinker, be curious, play, contribute, and learn. Have a heart! Check to see if those tickers are ticking! Sure we've been told we're full of blood, but how do we know? Starting with a pig heart, there is a lot to notice before we start cutting. What do you see? How many tubes go into and out of the heart?

Try to find all four. These can be tricky, so use dowels or pencils to mark the four ins and outs. Lightly pull the two parts so it opens like a book, and take a look inside. The first thing to look for are the four rooms of the heart. Some of the things you might try to find include: Valves -- the tricuspid and bicuspid valve are easily visible and divide the atriums from the ventricles.

Chordae Tendinae -- the "heartstrings," which pull on valves to open or close them. Try it out with a pair of tweezers. Papillary Muscle -- just like in our limbs, tendons need muscles to pull them, and those are the densely packed papillary muscles. These are fascinating, as unlike our other muscles, they are not attached to the skeletal structure.

Compare Ventricle Walls -- if you look at the right and left ventricles, one is much thicker than the other. Can you see which one? In the left ventricle, the heart has to contract to move blood throughout the whole body, so it has to have more muscle than the right, which brings blood a short distance to the lungs. Keep going! See what else you can find!

Have fun, be respectful in dissection, and keep exploring and learning. Did you make this project? Share it with us! I Made It!

The Oakland Toy Lab attyschack Reply 5 years ago. That's a great point, attyschack. I'll look into doing some edits! The Oakland Toy Lab dethanb Reply 5 years ago. What happens when the heart your dissecting starts beating get again? Thank you both!

Hey BryanB7! Thank you again. Icesphere BryanB7 Reply 5 years ago. Locate the dark red spleen, also in the tissues of the mesentery. Locate the two small dark pink lungs, which are on either side of the heart. Locate the heart, usually near the top of the liver. Here, you can clearly see the pylorus, where the stomach ends and the small intestines begin.

Food is moved down the esophagus by a process called peristalsis, which is coordinated muscular contraction of muscles in the esophagus. The glottis can prevent foreign objects from entering the lungs. Nares These small slits are called external nares and allow a frog to float on the surface of the water and still inhale oxygen.

Eustachian openingsThese small holes are the openings to the tympanum and are allow for equalization of pressure on either side of the tympanum. In some frogs, such as bullfrogs, they also allow the tympanum to act as an acoustic surface, helping frogs to produce their characteristically low noises. Frogs also have an ear, which is really a membrane which detects changes in air pressure, similar to the human ear drum.

The membrane is called the tympanum. Explore the external anatomy of the frog by clicking on various parts of the frog and learning more about each one. Begin with the fat bodies to allow you a better view of the organs. Then, explore each organ as you wish. If you prefer to follow instructions rather than explore on your own, click on the help function. On the next page click on the organ to learn about it, then remove it immidiately to the organ tray.

These small slits are called external nares and allow a frog to float on the surface of the water and still inhale oxygen. The frog's large intestine reabsorbs and recycles the water used in digestion. The large intestine leads to the cloaca for waste to be excreted. The small intestine is an organ at the end of end of the esophagus that stores and digests proteins, minerals, sugars, and vitamins in food into nutrients to be absorbed into the bloodstream.

The small intestine is coiled up and is connected with the large intestine, where the final stages of digestion occur.
