由於疫情其間,每天要宅在家中,小孩每天能學到的知識真的非常少!大女兒三年級,一大堆功課,英文文章可以叫她不斷重寫!但是數學,教她的方法她完全不聽,美國老師的方法,真的很笨!我的心真的很累!家中的iPad,給小朋友玩到爆屏幕。疫情期間,Apple門市關門,很難去修理iPad。還好可以向教育局免費申請iPad。只需要學生ID,教育局官網有中文服務。

干冰乾冰是二氧化碳的固體形式。[1]在正常氣壓下,二氧化碳的凝固點是攝氏負78.5度,在保持物體維持冷凍或低溫狀態下非常有用。其無色、無味、不易燃、略帶酸性。乾冰的密度各不相同,但通常約為1.4至1.6 g/cm3。乾冰能夠急速的冷凍物體和降低溫度並且可以用隔離手套來做配置。現在乾冰已經廣泛的使用在許多層面,乾冰在增溫時是由固態直接昇華為氣態,直接轉化為氣體而省略轉為液態的程序,因此其相變並不會產生液體,也因此稱做「乾冰」。要將二氧化碳變成液態,就必須將氣壓增強至5.1大氣壓才會出現液態二氧化碳。 此網站可購買乾冰http://www.articiceco.com/dryice.html
重點來了,之前兒子生日,訂了lady M蛋糕。配送蛋糕包含乾冰,利用這些乾冰,幫小孩上一節科學課。PS,乾冰溫度很低,小心接觸!可佩戴手套,不能長時間觸碰!

玩法二,干冰加入注水盆中,會發生大量煙霧!只要小朋友不長期觸碰底部,是不會有危險的。

玩法三,道具:一條繩,洗潔精。將條繩浸泡在洗潔精中,然後繩圍著乾冰的盆繞一圈,這樣煙霧會形成一個球體,用手指一碰才會爆!小孩特別喜歡!

玩法四,是最後的玩法!乾冰快沒了,直接加洗潔精入盆中,最後的小小乾冰和洗潔精結合,會形成一個個小泡泡,用手擠壓的話會形成煙霧!非常有趣!
