氣球、氣體和手的樂趣
在這兩週的課程中，我們將探索氣體（氦氣、空氣、氫氣和二氧化碳）及其特性。這樣做的方式很有趣，學習幾乎是偶然的，而不是設計的。

Learners will be guided through what makes gases different from liquids and solids. Demonstration-rich instruction that aim to educate while having fun. We will make carbon dioxide and each learner will be encouraged to have the necessary materials to follow along during that class. Nitrogen, oxygen, hydrogen and helium will be the focus of demonstrations and discussion. As the course title suggests we will compute how many helium balloons would be needed to "float away."
學習目標
Students will both watch and participate in. They will come to appreciate just how much gas balloons hold compared to their own lungs. They will laugh when they hear how voices change when the "air" passing through vocal cords has its air density modified. They will witness a miniature Hindenburg disaster.

其他詳情
父母的引導和規範
Learners will be guided through the use of vinegar and baking soda to produce and capture the carbon dioxide gas in a balloon attached to a plastic water bottle. Because the gas-filled balloon is under pressure the seal of the balloon to the water bottle opening needs to be secure. Leaky seals can result in spraying of vinegar and baking soda into the immediate area. If parent or learner would like a web-based preview visit link mentioned below. in external resources. The use of baking soda and vinegar to fill balloons or simulate a volcanic eruption are widely posted; especially in STEM (Science, Technology, Engineering and Math) web-based site.
供應清單
learners will follow along as make carbon dioxide gas trapped inside a balloon from the reaction of vinegar and baking soda. Having the necessary supplies is not a requirement, but a learner will feel left out if others are doing and they are left to watch only. Learners will need a small box of baking soda, a quart size bottle of distilled or white vinegar, a funnel, an empty plastic water bottle (16 oz size) , half a dozen balloons typical of what might be used at a birthday party.

Clifton Draper has a PhD in physical chemistry and after retiring early from Bell Labs he followed his dream of teaching elementary school science and math in New Jersey. As an elementary school science specialist he taught EVERY child in the school grades K - 6 twice weekly. He was selected by his peers for recognition in teaching excellence for the Governor's Award in 2007. More importantly he was often accused by the older students, parents, teachers and administration of being a "game show host" as much as a teacher. 評論
