2B COTTAGE GROVE SENTINEL February 10, 2016 © 2016 by Vicki Whiting, Editor Jeff Schinkel, Graphics Vol. 32, No. 9 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. o t e c n a t s b u s e n o h g u o h t s e s s a p t i n e h w ” s d n e b “ t h g i L g n i l e v a r t t s r i s i t h g i l e h T   . y t i s n e d t n e r e f i d a f o r e h t o n a e c n i S   . r e t a w e h t h g u o r h t s e s s a p t i n e h t d n a , r i a e h t h g u o r h t n i d n e b s y a r t h g i l e h t , r i a e h t n a h t e s n e d e r o m s i r e t a w e h t e h T   . l l e w s a d n e b o t m e e s y d n a c e h t s e k a m s i h T   . r e t a w e h t . n o i t c a r f e r d e l l a c s i g n i d n e b t h g i l f o s s e c o r p E EXPERIMENT V VALENTINE D DISSOLVE O OBSERVE S SOLUBLE BUBBLES B DENSITY C CANDIES H HEART B BENDS DRAW D R RAYS D DROP TEST AIR 1.
