To be effective
vaccines need to be kept cool, that is between 0 - 8°C. The cost of
each vaccine is not expensive - £3.50, but the need to transport the

- Put an ice
cube in a jam jar insulated with some paper (a roll of paper fitted
into the jar). The paper must have a top and bottom. How long does
it take to melt?
- Give each Six

that is where the ice cube lasts the longest.

the vaccines would be transferred to the best cold transport available.
