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 explore factors that impact cellular respiration in yeast, and have the opportunity gain experimental design skills.

In this lab, students look at enzyme activity by collecting and analyzing data.

Students use an online graphing tool to explore the ecological impacts of the introduction of the zebra mussel in the Hudson River.

Enzymes are protein molecules that have several functions. They can break down other molecules (digest), put molecules together (synthesis), as well as speed up chemical reactions. In this 5Es sequence students will observe enzyme functioning at different temperatures, and model optimal conditions for their enzyme using a simulation. They will then graph their data and use scientific language to describe their results.

Students will explore the processes associated with stream erosion by observing an actual small-scale erosional-depositional system.
