Just write

Este trecho encontrei na revista 科学教育研究 (kagaku kyouiku kenkyuu, Journal of Science Education in Japan). É um incentivo para aqueles que escrevem pouco e querem escrever mais.

Just write. Even if it makes no sense, just write. Even if it makes you feel stupid, just write. Even if it makes you feel vulnerable, just write. Even if you feel the world is turnin against you, just write. When you feel sleepy, just go to sleep and dream about that wonderful world you want to create. When you get up pick up your pen and continue writing. Because the truth is, when the mud settles down and the cloud clears away, everything becomes clear as day. In other words, you have written your world into existence because writing is both data and method. (Timothy, 1999, pp.52-53)

Salt crystals: a mini-course

From the 夏休み塩の学習室：　たいけん・しつもんコーナー　説明要領 (explanation essentials)
By たばこと塩の博物館

塩の結晶工作を作ろう
備品：　アルミ針金・手縫い用もめん糸（結晶工作キットをバラす）、星型工作見本、作品保存見本、作業用型枠（５台）、保温箱一式、ペンチ（５本）、はさみ（５本）
手順：　基本的には、演示しつつ作業させる。詳細は「自由研究ヒント集」参照。

①前日の夕方など、手の空いているときに、翌日の使用に見合う分量の予備を使っておく。針金を約３２ｃｍに切り、両端を曲げる加工をする。糸はぞの３倍程度の長さに切る。１回の工作を１０人として、１日
に１５回だとすると、１日１５０組必要。

②やってみたい子が数人集まったら、「３０～４０分くらい時間がかかる」と説明後、「自由研究ヒント集」を持っていることを確認し、説明をはじめる。持っていない子がいたら、屋台内の予備を渡す。※次回が何時からかをボードに書いて掲示。

③はじめに、完成見本を示しながら、「結晶をつけるのに一日かかるので、この屋台では、星型をつくるところまでしかできません。後は家で、これから説明する方法で、結晶をつけてみてね。」と断っておく。

④工作の前に原理の説明をする。「自由研究ヒント集」を参照させつつ。
塩が水に溶けることができる量は決まっている。（飽和の説明）
温度によって、塩が水に溶ける量が変わる。
高温飽和から冷めていくときに結晶が出て来る。
ゆっくり冷ました方が大きな結晶ができるので、「保温箱」を使う。
（先に作業して、後で「では家に帰ってから、この骨組みにどうやって塩をつけるかを説明します」という感じでもいい）

Experience Insights

Help lead your students to a broader understanding of themselves and the world around them with Insights, the new hands-on inquiry science curriculum for grades K-6 from Education Development Center.

This discovery-oriented program fosters process skills while helping students learn science through exploration and knowledge construction. The Insights curriculum is well-suited for use in urban settings or in culturally diverse communities. It was also designed to:

- Improve students' abilities to think creatively and critically.
- Encourage problem solving through experiences in the natural environment.
- Foster the development of positive attitudes about science.
- Bridge science concepts to current social and environmental events.
- Integrate science with the rest of the curriculum, particularly with language, arts and mathematics.
- Provide a teacher-friendly approach to managing a hands-on classroom science program.

Insights was developed with funding from the National Science Foundation. The development team included teachers from Los Angeles and San Francisco.

Insights is available exclusively through Optical Data Corporation. Call today for a free brochure. (800) 524-2481.

A Breakthrough in Elementary Science

Inquiry-centered, hands-on science units for grades 1-6.

Today, this student didn't cover the curriculum. He discovered it.
Together, he and his classmates did experiments, made observations, and drew
conclusions. They became scientists for the day, while learning scientific concepts they will use their entire lives.
For the teacher, it was easy with a unit from the Science and Technology for Children Program (STC). All the materials and apparatus needed for eight weeks of developmentally appropriate instruction were in the unit, including a step-by-step lesson guide. An in-service workshop helped the teacher prepare. The unit
included alternative assessment strategies and activities that helped integrate the lesson across the elementary curriculum.
The STC Program is developed by the National Science Resources Center, which is co-sponsored by the National Academy of Sciences and the Smithsonian Institution. Each unit is nationally field tested and reviewed by prominent scientists and educators. The sequence of units can serve as a complete elementary science
curriculum, or units can augment an existing program.
