LAB Biology Class

"Animal Vasculature" Students in Teacher Michael Salutin’s EP M6 Scientific Aptitude and Common Biology ST30250 class explored circulatory systems by observing three species of transparent crustaceans: Daphnia, Artemia (brine shrimp), and Ghost Shrimp. Using microscopes, students were challenged to locate and identify the beating heart and major blood vessels in each organism, carefully noting their position and rhythmic movement. They documented their observations by sketching and labeling the visible vascular structures. To quantify their findings, students then measured and recorded the heart rate per minute for each species. This comparative, hands-on lab allowed students to directly observe a live circulatory system in action and understand how vascular anatomy and function can vary across different small organisms

"Celery Vascular Tissue Dissection Lab" Students in Teacher Michael Salutin’s EP M6 Universal Biology 5 explored plant vascular tissues using a celery stalk and colored water. They placed a freshly cut celery stalk in dyed water and observed how the color traveled up the plant over 24 hours. By watching the leaves and stem tips change color, students could see the path of the water. They then dissected the celery, making cross-sections and longitudinal cuts to visually and microscopically identify the xylem tubes responsible for water transport. This simple, hands-on activity helped students understand how water moves through a plant and how to identify the specific tissues involved in this vital process.
