scientific reporting
Science is a great body of knowledge and experiences, gathered over the years
by many people called scientists.
Science changes every day. New ideas are developed and new discoveries
are made, and as a result older ideas and models change. One day, if you
decide to become a scientist, you might add to this body of knowledge.

Activity 1.1
Preserving food
Scientific skills: Manipulation, measurement, observation and
recording
You are going to investigate the factors that affect how quickly food
is spoiled (see Figure 1.7).

SAFETY
NEVER eat any food you have used in a science experiment.
Method
A You will need four pieces of the same type of fruit. It can be
anything from bananas or mangoes to berries. The fruit should all
be about the same ripeness.
B Place each piece of fruit on a petri dish, saucer, tile or piece of
cardboard. Look at each piece of fruit carefully, sniff it and then
draw and label each piece.
C Cover two of the pieces of fruit with plastic film or foil and label all
of the pieces with your name.
D Place one covered and one uncovered piece of fruit on the side
in your classroom. Place the other two pieces of fruit in a fridge.
Record the average classroom temperature and the temperature
of the fridge.
