Mr. Long's Biology Labs

The Frog is Exposed!

The frog dissection is the envy of every science student. This is a bullfrog. The black and white things are eggs in a female. You can also see the yellow fat bodies, ample intestines, the liver and some of the stomach that it partially covers.

The worm is very interesting

The students really love to dissect the earthworm. Even though it is a simple creature, the kids get a kick out of it.

Cutting the frog

Anticipation....

An empty stomach

In about 1 in every 4 stomachs a surprise can be found, usually a beatle. But nothing here.

Cutting up the arm of the starfish

Notice the radial symmetry.

Taking out the lens from the cow's eye

The crayfish!

The crayfish is a nice dissection. Not too messy like the starfish and lots of nice things to see. They have a little, muscular abdomen or tail, like a little lobster. They can be bought in the grocery, prepared properly, and eaten at home.

Mr. Long uses the flex camera to show how to dissect

I have always liked to use the camera to show dissections and other small details of other labs upon occasion.

Examining the mouth

Students are to examine all features possible before cutting open specimens.

Separating the tongue

Making incisions

Great internal view!

A fetal pig has many of the same organs as humans.

These girls are dangerous!

This student shows the intestines

The students I had in my lone biology class loved all the
dissections they did. I let them have a little fun. This student
took it up himself to see how long the intestines were.

Pig Brains!

One of my best students took up the task of removing the brain intact.
