CONTAINER B: was placed in a cupboard (cool)
CONTAINER C: was kept at room temperature (mild)

CONTAINER D: was kept on a window sill (warm)

Containers were left in their respective conditions for a week

After a week the slices of bread were removed from the containers and

placed next to each other.
e Learners repeated their investigation twice
The table below shows the results of the investigation
