Biology Dissections

Lung Dissection
Examine and dissect a pair of lungs to gain a greater understanding of the structure of the lung, the texture and the way it connects and works in relationship to the heart.

Heart Dissection
Dissect a heart to practically investigate the general structure of the heart and get a better understanding of the way the various blood vessels, valves, muscles and tendons come together and help make the heart function

Eye Dissection
Dissect an eye to practically investigate the general structure of the eye.

Kidney Dissection
Examine and dissect a kidney to gain a greater understanding of the structure of the kidney, the texture of the components and the way it connects and works within the body.

Errors in Experiments
Variables in a experiment: independent, dependent, controls
Types of errors: random errors, uncertainty, parallax error, systematic error, zero error
