Sam's blog post on our learning about preserving food

Food preserving

This term Room 8 and 9
have started  on science,
our topic for this term is food preserving. 

We first started by listing foods in order from
most water content to least , as a prediction. 

Then we researched the real water content and
listed them too. The class wondered if water content
had something to do with rotting! 

We noticed this because we have conducted an
experiment to do with the lifespan of bread, apples and
crackers and in different storage.
A freezer, a plastic container, a plastic ziplock bag and 
a paper bag. 

Here is a table of the results after 10 days

Food	Paper bag	Plastic bag	Plastic container
Cracker	Oil seeping onto paper.	No change.	No change!
Apple	Shrivelled ,dry, no mould	Mould growing slowly. squidgy	Damp, mouldy and fast growing
Bread	No mould, dry and crunchy.	Some growing mould.	Completely mouldy- fast growing.

After, with a buddy we chose a food

and researched it (any food)
to make a presentation about that
food and how it can be preserved.

Room 8&9 really love food science!
