The chemosensory response lab addresses cell response to a variety of substances, from avoidance/attraction response to modification of ciliary beat, and presents optional sections to allow teachers to tailor module use to specific classroom levels. Middle school students examine the response of the cells to simple substances like herbs, spices, or citrus peel, some of which are provided with the kit, or they can design their own experiments to test the avoidance/attraction respose to a variety of substances of interest to them. High school students can examine more sophisticated chemical responses, for example to GTP. This lab has been adapted for use in classes ranging from 4th/5th grade through AP biology.

Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
Conduct an investigation to provide evidence that living things are made of cells, either one cell or many different numbers and types of cells.
Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.
Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.
Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
Use a model to describe that animals’ receive different types of information through their senses, process the information in their brain, and respond to the information in different ways.
Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.
Use evidence to construct an explanation for how the variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing.
The central purpose of scientific inquiry is to develop explanations of natural phenomena in a continuing and creative process.
Beyond the use of reasoning and consensus, scientific inquiry involves the testing of proposed explanations.
The observations made while testing proposed explanations, when analyzed using conventional and invented methods, provide new insights into natural phenomena.
Organisms maintain a dynamic equilibrium that sustains life.
Plants and animals depend on each other and their physical environment.
