Which liquid evaporates the fastest: water, 7 Up, honey, hand

```Mrs. Alvis’
Class
Science Inquiry Showcase 2011-2012
Which liquid will evaporate the most
over 7 days: water, Cherry 7 Up, dark
corn syrup, hand sanitizer, vinegar, or
vegetable oil?
Hypothesis
• Most of us think water will evaporate the most because it is natural, doesn’t
have any chemicals, and the other liquids are stickier than water.
• Some of us think Cherry 7 Up will evaporate the most because it
has bubbles that can make the Cherry 7 Up float away faster.
• One student predicts that hand sanitizer will evaporate the most because it

Results
• Over the 7 days, dark corn syrup and vegetable oil did not
evaporate at all.
• The hand sanitizer evaporated the most.
• Cherry 7 Up evaporated the second fastest.
• Vinegar evaporated the third fastest.
• Water evaporated the fourth fastest.
• Cherry 7 Up and vinegar are the only liquids that evaporated on
Day 2.
Conclusion
• Claim – Hand sanitizer evaporated the most of all the liquids.
• Evidence – On day 7, hand sanitizer had 86 ml left, the least
amount of all the liquids.
• Reasoning – We think hand sanitizer evaporated the most because
of the chemicals that are in it. Also, we know that when we use
hand sanitizer, it dries faster than water on our hands. We think
that maybe the more it is exposed to air, the quicker it will
evaporate.
Thoughts from the Class
hand sanitizer because I
thought the water would
faster.” – Lily
“Ievaporate
think everyone
expected the
dark corn syrup
to not move
because it is so
sticky.” – Josie
“I was surprised because at
first 7 Up was evaporating
the fastest, then the hand
sanitizer evaporated the
fastest.” – Reese and Katey
