Microbes growing on agar plates - hand washing activity

Lesson presentation on the need for handwashing.
Slide 2 is a learning framework.
Slides 3-4 are for you to print off for yourself. I’ve just copied and pasted the text that accompanies the video clips that are hyperlinked on those slides.
Slide 5 shows how to set up agar plates to grow microbes. Use permanent markers to label the bottom of the agar plate. Add name to the rim of the lid then keep lid on with 2 small pieces of tape. DO NOT SEAL. When microbes grown you will be able to see through the lid (or base) without opening it.
DO NOT OPEN CONTAMINATED PLATES. When plates have been observed in a second lesson, use slide 6 to draw microbial growth and conclusions. Label diagrams identifying differences between bacterial colonies and fungal growth. COLLECT PLATES AND GIVE TO TECHNICIAN TO AUTOCLAVE.
