Year 10 DNA Pracs.

I wash and reuse zip lock bags all the time. Eventually they do have to go in the bin, sadly. Fortunately there are now some excellent compostable bags available. (Thankfully, my head teacher would never instruct me to not reuse something.)

I find the regular ones don't even last the prac. Maybe our kids are a bit too rough with their smooshing of the fruit? They usually have to double bag them to avoid too many leaks.

Surely there's a way to "smoosh" fruit without a bag - mortar and pestle? Sounds like the bags do a pretty ordinary job.

I've attached what we do. It is a bit more intensive than the zip lock bag method, but it eliminates the use of bags which is good for the environment.

Wayne thanks for sharing, that method looks great! So much background detail as well
