This is one of a series of laboratory activities built on the 5-E approach. Each activity provides opportunities for students to ENGAGE ←→ EXPLORE ←→ EXPLAIN ←→ ELABORATE ←→ EVALUATE.
In this dry lab, students examine an experimental set-up designed to test three environmental components of the brine shrimp, Artemia: light, pH, and temperature. After answering questions about the materials and process in each experimental iteration, students write an “if… then…” hypothesis indicating their thinking. After completing their hypotheses and answering questions about each environmental condition, students receive a copy of a data table generated by an anonymous lab group. They graph the data and write a conclusion. An optional activity is to design an additional experimental set up for another variable in the shrimps’ environment. Answers to all questions and rubrics for the conclusion and experimental design are included in the Teacher’s Guide.
