Innovating Science® - Introduction to Basic, Selective, and Differential Media

In this activity, students will learn about the different types of media that can be used to grow bacteria. They will predict which media will support the growth of different bacteria, then streak the different media with bacteria cultures to observe their growth. The bacteria growth will be evaluated to determine if students' predictions were correct.
