THE HEAT IS ON
INTRODUCTION
|
![]() It's summer. Mom has asked you to go out
and pull a few weeds. Hey, it's not your idea of a great
time, but it pays the bills. Good thing your living expenses
are pretty cheap as a 12-year old. You head out the door,
grab the little shovel thing, and walk to the garden. "Hey,
this isn't so bad," you think. "Maybe if I take my time, Mom
will get my little sister Gerty to rinse and load the lunch
dishes and wipe the counters." Time flies. Well at least it
does for about seven minutes. You have actually pulled one
weed, eaten two handfuls of strawberries, and collected
three worms to torture Gerty. "Wow!" you say to yourself,
"This is hard work." The heat is on. That big
ball of fire in the sky is beating down on you,
taking it's toll on your energy level. You pull
another pesky weed from the tomato section. "Whew,"
you say almost wiping your forehead, but then
deciding against it. "I don't think I can stand
this hard work much longer. Maybe another
strawberry or two." You look at your watch. You
look at the sun. "Does mom really expect me to do
this in the middle of the day? Maybe I 'll just rest
under the apricot tree for a few minutes." Twenty
minutes after you begin your task, you drag back to
the house. The fruit punch arrives. Before
you allow yourself the pleasure of that first cool,
quenching sip, you place the glass against your
forehead and instantly feel the chill of the cool
drink lessening the memories of your twenty minutes
of torture in the garden. You finish the drink, set
the glass on the end table, and reach in your
pocket. You have cooled down, but the worms still
feel plenty warm. Time for some fun. "Gerty. .
." Of course the above story is pure fiction. You, unlike the 12 year old in the story, always finish your chores and would never tease your little sister or brother. But some things in the story are very real. Summer is a great time of year. If you go to a school where you have summer vacation, it is probably the best time of year. But many people find that summer brings and unwanted guest - heat, and lots of it. The heat is on. |

How would you describe heat to someone who has no concept of the word? Think about it. Maybe you would mention that heat is something that makes you feel good-like a warm blanket on a cold day. Then again, maybe you would say that heat is something that makes you hurt-like the hot iron you forgot to unplug (Ouch!). Well, just what is this heat thing anyway? We never thought you would ask. In this unit you will learn all about heat. You will also get to do lots of fun science experiments and activities to learn about heat. So what are you waiting for? IT'S TIME TO MEET THE HEAT!! |
