There are a lot of candies on
Valentine’s Day. And, to protect your teeth and health,
we suggest using some of them
for science experiments!
Here’s some heart-healthy
work outs to try this month!
Can you do at least one of
these each day for one week?
STUFF YOU’LL NEED:
STUFF YOU’LL NEED:
water
pencil
clear cup
lollipop
WHAT TO DO:
1. Place a Valentine’s Day lollipop in a clear cup. Draw a
picture of the lollipop in the cup here:
water
clear cups
Valentine candies
WHAT TO DO:
1. Get three or four diferent kinds of Valentine’s Day candy and one cup for each kind.
2. Fill each cup halfway with water.
3. Drop a diferent kind of candy in each cup.
4. Check the candy every 15 minutes to observe how it has changed. Describe with
words or pictures how the candies change each 30 minutes.
15 MINUTES:
30 MINUTES:
45 MINUTES:
60 MINUTES:
Run in place for 60 seconds.
Rest for 60 seconds. Then run
in place for three minutes.
Stand very still and place your
hand on your chest and feel
your heart pumping!
2. Add water to ill the cup halfway. Draw a picture of
the lollipop in the cup with water here:
WHAT YOU ARE OBSERVING IS SOLUBILITY (There’s a great science word!)
Play your favorite song three
times in a row and dance,
dance, dance!
When something dissolves in water, it is called soluble. Diferent things dissolve at
diferent times. And some things don’t dissolve at all.
What is diferent between the two pictures?
Scientists are good
observers. Test
your powers of
observation with
this game for three
or more players.
1. Pick a picture or
drawing in the
newspaper.
2. Players take turns
telling a fact or
detail about it.
3. When a player
can’t add a new
fact, he or she
is out.
Standards Link: Reading
Comprehension: Follow
written directions.
STUFF YOU’LL NEED:
Why do you think the lollipop looks diferent in the
cup with water?
clear cup
candy hearts
club soda
Hold this paragraph up to a mirror to discover
the science behind this experiment!
WHAT TO DO:
1. Fill the cup with club soda (any clear carbonated soda will work).
2. Drop a few candy hearts into the cup.
3. Do some hearts lip or loat? Keep observing.
WHAT’S HAPPENING?
The carbon dioxide soda creates bubbles that form on the hearts.
If enough bubbles form, the candy is lifted towards the surface.
But as bubbles pop, the candy sinks again until more bubbles form.
Practice cartwheels and hand
stands for 5 minutes.

The scientist was able to
observe changes in the
candy in the glass of water.
Try to use the word observe
in a sentence today when
talking with your friends
and family members.
Before and After

change? What are the planned and/or
unplanned effects of the change?
