All living organisms, regardless of how they get their own food, need to carry out cellular respiration in order to harness the energy from that food. In this instructional sequence, students will experiment with a very simple organism that carries out cellular respiration, design a new experiment using the same materials, and analyze problems based scenarios based on what they learned. The sequence allows teachers to build in opportunity to focus on Experimental Design, Graphing and Diagramming Skills, in addition to topics in Cellular Respiration.

In this lab, students observe the effects that toxins have on the heart rate of Daphnia.

Humans are complex organisms that maintain a narrow set of internal conditions through a system of feedback and communication mechanisms between multiple organ systems. In this unit, students will explore how body systems interact to effectively monitor and respond to both internal and external environmental changes. Students complete both Making Connections (a New York State required lab) and a human thermoregulation laboratory, both of which focus on skills of experimental design.

In this lab, students investigate how salinity affects hatching of the eggs of a particular type of brine shrimp.
