Have you ever rubbed(擦) your hands together when they get cold? Why do we do that? We do that for friction(摩擦). Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let’s discover friction!

●________1.__________

Soap        Water         Your hands

(1). Make sure your hands are dry.

(2). Rub your hands together until you feel the heat of your hands.

(3). Now, use soap and water to get your hands very slippery(滑的).

(4). Try to make friction happen while your hands are slippery.

(5). Please write down what has happened.

●________3.__________

Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.

●________4._________

(1). Friction happens when you stop your fast running bike.

(2). Ancient people made fire by rubbing two pieces of wood together. Friction happened though they didn’t know it.

Once　upon　a　time,　a　young　man　was　standing　in　the　middle　of　the　town　announcing　that　he　had　the　most　beautiful　heart　in　the　world.　A　large　crowd　gathered,　and　they　al　praised　his　heart　for　it　was　perfect.

    Suddenly,　an　old　man　appeared　and　said,　“Why　,your　heart　is　not　as　beautiful　as　mine.”

    The　old　man’s　heart　was　ful　of　scars（伤疤）.　Some　pieces　of　his　heart　were　removed　and　some　pieces　from　other　people　were　put　in,　but　they　didn’t　fit　quite　right.　So　there　were　several　jagged（锯齿状的）edges.　In　fact,　there　were　stil　some　holes　in　his　heart　where　the　pieces　were　missing.

    The　 young　 man　 laughed,“Comparing　yours　with　mine,　mine　is　perfect　and　yours　is　a　mess.”

    “Yes,”said　the　old　man.　“But,　every　scar　shows　that　I　took　out　a　piece　of　my　heart　and　gave　it　to　a　person,　and　often　he　gave　me　a　piece　of　his　heart　in　return.”

    “Why　do　you　have　some　jagged　edges　in　your　heart?”asked　the　young　man.“Because　the　shapes　of　the　pieces　weren’t　the　same.”“Then　the　holes?”“Sometimes　I　gave　pieces　of　my　heart　away,　and　the　other　person　hasn’t　given　back　a　piece　of　his,　so　… but　I　don’t　care.”“How　come?”“They　remind　me　of　the　love　we　shared.”

    The　young　man　was　deeply　moved.　He　walked　up　to　the　old　man,　took　a　piece　of　his　heart　out　and　gave　it　to　the　old　man.

    The　old　man　placed　it　in　his　heart,　then　took　a　piece　from　his　old　scarred　heart　and　placed　it　in　the　wound（伤口）in　the　young　man’s　heart.　It　fitted,　but　not　perfectly,　as　there　were　some　jagged　edges.

    The　young　man　looked　at　his　heart,　not　perfect　any　more　but　more　beautiful　than　ever.

    How　sad　it　must　be　to　go　through　 life　 with　 a　 whole　untouched　heart!
