Purpose: To determine where in the school environment you would find the greatest numbers and kinds of microorganisms.
Materials: Petri dishes of nutrient agar, Masking Tape, Markers, Cotton swabs
This lab has always been a favorite of my Biology I students, but the lab is appropriate for middle school aged students as well. Biology students love growing bacteria, and in this lab they try to determine to location in the school that has the most bacteria. There is really nothing very scientific or reliable about the data, but it is a fun activity that your students will love. Students do not need much background information to complete this lab, so you can use this lab as an introduction to your unit on microorganisms, or it works just as well as an ending activity.
Note: This product is also included in my bundled unit lesson plan that can be viewed by clicking this link: Viruses and Bacteria: Complete Teaching Unit containing 14 products
Your 5 page download will include a lab that is ready to be photocopied and passed out to your students. It will include: Title, Introduction, Purpose, Materials, Safety Precautions, Procedure, Observation Questions, and Data Tables. You can chose to have your students write their own lab reports or you can have them use the included Student Data Sheets on which they can record their data and answer the questions.
I have also included a Teacher Preparation Page. This will include pre-lab discussion, answers to all questions, and post lab follow up ideas.
You will download two versions of the lab: A pdf version and an editable Word document.

Science Rules (TpT Seller)
Exciting lab, authentic topic, good to dispel ideas of where microorganisms are thought to be the worst and where they actually are; lab well explained, provides materials list, clear procedures, student inquiry with guided questions. Additional extensions may be applied once lab is conducted. Recommended!
