STEM Project: Changing Environments Strand: Effects of Traits on Survival

Standard 3.2.6: Design a solution to a problem caused by a change in the environment that impacts the types of plants and animals living in that environment. Defne the problem, identify criteria and constraints, and develop possible solutions. Examples of environmental changes could include changes in land use, water availability, temperature, food, or changes caused by other organisms.
