Your Body: A Bacteria Incubator!
Students use string, a petri dish, water, wipes, and other materials to collect bacteria from their body. In this bacteria lesson plan, students use ingredients to collect bacteria, observe it, predict what will happen over time, and...
Curated OER
Potato Petri dish
Students participate in an experiment to understand how germs grow. In this potato experiment students use their hands to touch a potato and leave it to see what grows on it. Students also observe a disinfected potato piece. Students the...
Curated OER
Microorganism Multiplication
Sixth graders explore biology by viewing video clips in class. In this microorganism identification lesson, 6th graders identify the types of organisms that can feed small animals such as algae and protozoans. Students view video clips...
Curated OER
Antibiotic Resistance
Students conduct an experiment to examine the effects of six different antibiotics on two different types of bacteria. They monitor Petri dishes with bacterial cultures and antibiotic soaked disks. They relate the bacteria growth...
