Els nois i noies de la classe de sis\u00e8 estem treballant l’energia t\u00e8rmica. Hem apr\u00e8s que hi ha materials que amb la calor es dilaten i augmenten de volum. Hem fet una experi\u00e8ncia al laboratori i hem comprovat que una bola de metall que passa molt b\u00e9 per una anella, quan s’escalfa es dilata i li costa passar per l’anella. Tamb\u00e9 hem comprovat com funciona el term\u00f2metre quan augmenta la calor.
\nPer comprovar la conducci\u00f3\u00a0de la calor\u00a0dels diferents materials, hem enganxat a la part c\u00f2ncava de dues culleres un p\u00e8sol amb mantega. Una cullera era de fusta i l’altra de metall. Hem posat les culleres amb els\u00a0m\u00e0necs\u00a0cap avall dins un pot amb aigua calenta i la mantega de la cullera de metall s’ha fos primer i el p\u00e8sol ha caigut. Sabeu\u00a0per qu\u00e8? Perqu\u00e8 el metall condueix millor la calor que la fusta.
\nPer acabar, hem comprovat que sense oxigen un foc s’apaga.<\/p>\n
