日本代购-メーカー希望小売価格はメーカーカタログに基づいて掲載しています 商品説明 ■DVD（約45分）『わかるよ！力のはたらき2』【DVD】【知育教材】【理科】 ボートが進むときの支点は？月の重力は？身の回りにある理科がおもしろくなる！ 理科って面白い！と思えるようになる とにかく理科が嫌い、面倒くさい、と思うのは… ⇒⇒ なぜ？どうして？と気づくまで、が大切なのに、何を実験するのかよくわからないまま実験をさせられたり、とにかく公式を覚えよう、と詰めこまれたりするから 当社の理科シリーズをみると、毎日とても身近なところで、たくさんの理科の法則にふれていることに気づくことができます。そう思えたら大正解。理科は、面白く、興味深く、知識欲をかきたてるとても面白いもの、になっていくこと、まちがいなし！ 組み合わせかっ車を使うと24kgの物が3kgの力で動く、でも動かすためにひもをひく距離は8倍も長い… てこも、力で楽をすると、動かす距離は必ず大きくなる… 力のはたらき方のしくみをわかりやすい表現でくりかえしきかせることで、原理が知識の土台としてしっかり記憶に残ります。勉強に必須の数値の計算や解法だけではなく、物理の原則を、当たり前のこととして知っておくことが、興味の原点になります。 てこや輪軸、浮力やふりこのしくみを使ったものは身の回りにたくさんあります。 なぜつりあうのか、なぜ小さい力で重い物が動くのか…さらには重力、引力など、日常生活と深くかかわりのある「物理」の面白さを「力のはたらき1、2」をとおして、楽しく学んでほしいと願っています。 ◆てこ ・てこの3点、3点間の距離とはたらく力 ・てこの利用、回転力 ・つりあいと比、てこの重さを考える ・太さが一様ではないてこ ・支点と重心、てんびんとシーソー ◆かっ車 ・定かっ車、動かっ車、組み合わせかっ車 ◆輪軸 ・輪の大きさとはたらく力 ◆ばね ・ばねの性質 ・作用・反作用とつりあい ・のび方の違うばね ・重さと質量、月と地球の重力 など
