Dissection in biology provides a hands-on education above and beyond reading a textbook. By seeing, touching and exploring different organs, muscles and tissues inside an animal and seeing how they work together allows you to really understand your own body and appreciate the amazing world around us. And it's not hard  - you can dissect a kidney right at home using an inexpensive specimen with a dissection guide and simple dissection tools! Many doctors, surgeons and veterinarians report that their first fascination with the body started with a biology dissection class.

In today’s dissection, we’ll be looking at a kidney. Kidneys are critical for removing toxic waste and regulating the levels of water, sugars, salts, and acids in the bodies of mammals. There are many things that make a kidney interesting, including its unique bean shape and the fact that it contains about a million microscopic structures called nephrons that are key in the blood filtration process.

In today’s dissection, we’ll be looking at a sheep heart. Like humans, sheep have four-chambered hearts. Hearts are an essential organ--they pump blood through your body to keep you alive!

In today’s dissection, we’ll be looking at a sheep brain. Brains, while still not entirely understood by biologists or psychologists, are critical for movement, respiration, thought, memory, processing sensory signals, and more. What we talk about in today’s dissection just scratches the surface of all there is to know about the brain, which is the most complex organ in the human body.

In today’s dissection, we’ll be looking at a perch. Perch are members of the phylum Chordata. There are many things that make perch interesting: they are bony fishes which make them “true” fishes, they live in both freshwater and saltwater, and their diets change based on how big they are.

In today’s dissection, we’ll be looking at an earthworm. Earthworms play an important role in their ecosystem--when they tunnel through dirt they mix nutrients which helps make the soil healthy and able to support plant life.

In today’s dissection, we’ll be looking at a frog. Frogs are members of the Class Amphibia. There are many things that make frogs interesting: they live both in water and on land, they actually begin life in water as limbless tadpoles, and some can change color depending on their environment.

In today’s dissection, we’ll be looking at a crayfish. Crayfish are members of the phylum Arthropoda. There are many things that make crayfish interesting: they dwell at the bottom of streams, rivers, and ponds; they feed on just about anything that comes their way (that’s why they’re called freshwater scavengers); and they have many appendages that help them save energy.

The shell of chicken eggs are made mostly of calcium carbonate (CaCO3), which which reacts with distilled white vinegar (try placing a raw egg in a glass of vinegar overnight). The shell has over 15,000 tiny little mores that allows air and moisture to pass through, and a protective outer coating to keep out harmful things like dust and bacteria.

We're going to peek inside of an egg and discover the transparent protein membrane (made of the same protein your hair is made up of: keratin) and also peek in the air space that forms when the egg cools and contracts (gets smaller). Can you find the albumen (the egg white)? It's made up of mostly water with about 40 different proteins.

cheetahImagine a little box of spoons. Now, imagine on moving day that that box of spoons is put into a bigger box with all of the silverware. Now, imagine that that box of silverware is placed into an even bigger box with all of the kitchen stuff.


Now, imagine that the box of kitchen stuff is placed in the moving truck with all of the stuff from your house. In the end the within the truck is all of the stuff from your house, within kitchen box are all of the things from the kitchen, and within the spoon box are just the spoons.


In the same way, we will group organisms according to their physical appearance into hierarchical categories.

Imagine leaving your home every year and traveling hundreds of miles to a completely different place, only to return home later in the year. As amazing as this sounds, this is exactly what many species of birds do in a process called migration.

When birds and animals drink from lakes, rivers, and ponds, how pure it is? Are they really getting the water they need, or are they getting something else with the water?


This is a great experiment to see how water moves through natural systems. We’ll explore how water and the atmosphere are both polluted and purified, and we’ll investigate how plants and soil help with both of these. We’ll be taking advantage of capillary action by using a wick to move the water from the lower aquarium chamber into the upper soil chamber, where it will both evaporate and transpire (evaporate from the leaves of plants) and rise until it hits a cold front and condenses into rain, which falls into your collection bucket for further analysis.


Sound complicated? It really isn’t, and the best part is that it not only uses parts from your recycling bin but also takes ten minutes to make.

How does salt affect plant growth, like when we use salt to de-ice snowy winter roads? How does adding fertilizer to the soil help or hurt the plants? What type of soil best purifies the water? All these questions and more can be answered by building a terrarium-aquarium system to discover how these systems are connected together.
