The experiment aimed to determine whether plain water or sugared water would evaporate faster. The experimenter poured equal amounts of water into two identical cups, adding sugar to one cup. After leaving the cups overnight, the water level in the plain water cup had decreased slightly more than in the sugared water cup. This led to the conclusion that plain water evaporates faster than sugared water, because the dissolved sugar in the sugared water absorbs water from the atmosphere and requires more energy to evaporate.

1. Experiment Conducted by:
Alan 5/1

2. Introduction
 Aim of the Experiment
 To find out which will evaporate faster; Sugared water or plain water
 My Hypothesis
 I believe that plain water will evaporate faster than sugared water

3. Apparatus needed
2 Identical cups
with the same
surface area
A Beaker
A container
containing
sugar
The only variable that is changed is that 1 glass contains sugar while the other doesn’t

4. Steps to do an experiment

5. STEP 1
Pour some water into the
beaker. Preferably 200 ml. Pour
the same amount into both
glass. Both amt. of water in
each glass must be the same.
Preferably 200 ml each.

6. STEP 2
Mark each glass A and B. Then
decide which glass you want to
pour sugar into. In my case, I
put sugar into glass A.

7. STEP 3
Pour all the sugar in the
container into the glass that you
have chosen to put sugar into.
Then stir it well.

8. STEP 4
Then, mark the water level. This
part can be very tricky, but you
will have to do it right. If not,
your experiment can fail.

9. STEP 5
This will be the most longest
and final step. You will have to
leave the glass jar overnight or
longer for better results. In my
case, I’m leaving it for 24 hrs.

10. Conclusion and Explanation
 Conclusion
 Glass A has a slightly higher water level
than Glass B.
 From this, we can conclude that plain
water can evaporate faster than
sugared water.
 Explanation
 Water is colourless and odorless, and
sugar water is made by dissolving sugar
into water. Sugar can absorb water
from the atmosphere, and this can stall
evaporation. Less energy is required to
evaporate water than sugar water
when the conditions are constant and
there is a significant amount of sugar in
the sugar water.

11. THE END!
