This authentic research experience lesson teaches the core concept of systems and the competencies of quantitative reasoning, communication, and the ability to apply science. The research is student driven, the results are unknown, and the students engage in an iterative process to gather data, collaborating with classmates.  It is designed for first-year biology majors, in a class size of 15-30 students who can work in groups of three.  Students will learn to properly design an experiment, work as teams, analyze data, evaluate conclusions, and communicate findings to others. Additionally, this lesson also incorporates self-reflection and peer assessment when students produce a poster as a summative assessment. Over a five–week period, students will explore how an abiotic factor affects growth, reproduction, and survival of Daphnia.  Students are asked to compare their results to published literature. By the end, students should have a better understanding of science as an ongoing process where results are being updated and furthering the state of knowledge.
