Re: [DIYbio] Activity to demonstrate the disinfectant action of chlorine for young (12-16)

Hi Nathan,

You suggest this type of microscope?

Thanks,

Will you be able to have a microscope available, or maybe the projection microscope that shines a laser through a hanging droplet? I wonder if you could find a yeast cell, then add some bleach and watch it dissolve.

Hi Tom,

4 to 6 participants at a time because space is small

US$10,00 for each group of 4 to 6 participants

The idea is to use scrap and buy only what is strictly necessary, such as agar (for edible use).

Thanks,

Markos

All good answers already. Before I share my suggestion / protocol, can you reply back with 2 details:

1. No. of participants (maximum expected), and

2. Your maximum budget.

Hello,

I'm organizing a citizen science course with diy activities about water
for young people aged between 12 and 16 years old.

I want to include an activity to demonstrate the disinfectant action of
chlorine, and I need to find an activity that uses affordable materials
and culture media and a protocol that is easy for participants to
replicate with kitchen utensils.

But as a Chemist I ask a help to suggest examples on web so I can save
time searching on Google.

Thanks,

Markos
