A biofilm is any group of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPS).
Career Requirements. Kindergarten teachers in public schools are required to have at least a bachelor's degree in education and teacher certification for the state in which they work. Certification typically requires candidates to complete student teaching requirements and pass any required professional exams.
Step 2: Earn a Bachelor's Degree. Kindergarten teachers ordinarily major in elementary or early childhood education in a bachelor's degree program. Which major one will pursue depends on the school and the state licensing requirements.
