They're Everywhere: Bacteria

This activity’s objectives are aligned with the National Science Education Standards, specifically those related to Science as Inquiry and Physical Science. In this activity, students will grow and observe bacteria collected from a variety of locations, and then compare relative amounts of bacteria living in different parts of their homes, classroom, or school. Students will design an experiment, make observations, and draw conclusions.
