Bacteria Lab I: Preparing Agar Plates and Culturing Bacteria
Bacteriologists prepare their own agar plates and culture bacteria on them. The procedures for both tasks are delineated, and questions are posed, but no materials list is printed. Also, the exact amounts of water and nutrient agar are...
Exploratorium
Salty Pits
Yuck, does my deodorant kill that? To test whether deodorant is anti-bacterial, class members use petri dishes to grow control bacteria and bacteria from sweat, and then compare them to see if deodorant effects the growth.

Bacteria's Role in Food
Young scholars grow bacteria cultures on agar in petri dishes and do a plate count. They participate in a yogurt making lab to see how bacteria produce lactic acid. They prepare a recipe and identify fungi, fermentation and the role of...

Activity 2: How Do You Get Your Energy?
Students receive informational handouts about photosynthesis, chemosynthesis and tubeworms (included with the lesson). Using the "Bacteriology Experiment Plan" handout, students compare the amount of bacteria found in two locations. They...

Factors Which Affect Corrosion
Students investigate the factors which affect corrosion. For this corrosion lesson plan, students experiment with 2 nails, copper wire and magnesium ribbon placed in a petri dish of agar solution, potassium ferricyanate and an indicator....
Curated OER
Life Traps
Learners participate in a lab activity in which they collect microbes on an agar plate. After discussing microbes and where they might be found, they trap microbes in the Petri dishes following specific guidelines. They observe any...
Curated OER
Predicting the Growth of Microorganisms
Students determine where microorganisms might be found around their school. In this scientific investigation lesson, students collect cultures from various locations and place these in petri dishes. They incubate the cultures to see if...
Curated OER
Spud Smear
Learners study various samples of microorganisms in petri dishes. In this microorganism lesson, students place various samples of items in petri dishes and observe them after several days of incubation.
Curated OER
Bacteria: The good, the bad, the ugly
Seventh graders conduct an experiment. In this bacteria lesson plan, 7th graders list living and nonliving things and brainstorm the characteristics they share. Students are divided into two groups where they put samples of hand soap...
Curated OER
DEMONSTRATING AN EPIDEMIC
Students experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables the student to determine the originator of the "epidemic." They transfer live bacteria by hand contact, then...

Bacteria Lab II: Effect of Bacteriocides
Written to follow "Bacteria Lab I: Preparing Agar Plates and Culturing Bacteria," also found via the Lesson Planet site, this lab sheet instructs your microbiologists to test a bacteriocide for effectiveness. In the preceding lab, they...

Making a Streak Plate
Cultivate bacteria with a straightforward lesson featuring agar. Scholars create a streak plate on agar to ideally create colonies of bacteria or yeast that are growing separately from each other. The resource introduces the simplest...
Curated OER
Dirt Life
Students select and collect soil samples from a variety of locations (schoolyard, home, etc.). They do this lab after an interest-generating discussion about "dirt" and microbes. Students make a dilution in sterile water, plate it on a...
Curated OER
Backyard Bacteria
Students experiment with different bacterias that they found and make predictions of their growth. For this investigative lesson students use petri dishes to grow their bacteria then summarize what has happened.
Curated OER
Science: Conditions for Slime Mold Survival
Students perform experiments to determine the nutritional needs and physical space requirements for slime mold to survive. After formulating hypotheses, they seal the petri dishes and set up the experiment along with two controls. ...
Curated OER
Petri-fied of Bacteria
Students examine the existence of bacteria all around them and consider the roles, both positive and negative, that bacteria play. Over a period of several days, students conduct an experiment in which they predict, determine, log, and...
Curated OER
Multiplying Microbes
Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.
Curated OER
Life Traps - Lesson Plan
Students observe and discuss microbes. In this microbes instructional activity students complete a lab activity where they grow microbes in petri dishes and discuss their findings.
Curated OER
Diffusion
Young scholars investigate diffusion using different solutions of chemicals placed in agar dishes. In this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in...
