Game teaching guide
What children will practise
Understand food preservation as stopping micro-organisms, match methods to foods, spot signs of spoiled food, and know the right temperature for each kind of storage.
What's in the worksheet
4 rounds, a matching game with 4 pairs each - Drying with removing moisture; pickling with acid or salt; boiling down with removing water and adding sugar - Fish with drying or salting; fruit with boiling down or candying - Mould with fungus growing; a swollen packet with gas from micro-organisms - The fridge's main compartment with about 4 degrees Celsius; hot food for serving with above 60 degrees Celsius
How to use it in class
Use in the Grade 5 food-preservation unit, before making pickles or dried bananas. 7 minutes. - Play solo, then each child finds one preserved food at home and names its principle - For round 3, show a picture or a safe real example, such as mouldy bread in a sealed bag - If many miss round 4, ask "Which part of the fridge turns water into ice?" - Play it linked to a class and the scores go into the class gradebook.
Common sticking points
- In round 1, swapping boiling down and pickling, since some fruits are done both ways; look for the words sugar and salt - In round 4, matching the freezer to about 4 degrees, thinking 4 degrees is already very cold - In round 3, swapping colour change and sour smell, as turning and deteriorated both mean spoiled
