Puedes poner lo típico de bicarbonato de sodio con vinagre, o mentos con coca...una vez que se juntan estos compuestos al reaccionar el vinagre con el bicarbonato de sodio, el dióxido de carbono se libera a la atmósfera ya que el frasco está abierto. En este caso el peso disminuye. Te adjunto en una imagen la ec. de como el ácido acético reacciona con el bicarbonato de sodio para formar acetato de sodio y dióxido de carbono.

Otro que puedes hacer es hervir agua, el agua se transforma segun la temperatura, al hervirse(ebullición) se convierte en vapor. Cumple con la ley de conservacion, la energía no se destruye solo se transforma.para hacer el experimento puedes comparar cuanto pesaba el líquido antes de aplicarle calor.

Puedes aprovechar y realizar otro en el que congeles el agua.

También si disuelves azucar en algun liquido cumple con la ley.

Otros ejemplos....una vela al derretirse, el proceso de digestión, comparar el peso de un refresco con y sin burbujas



Espero haberte servido! Avisa cualquier cosa y si gustas ponerme unos pts estaría genial. Mucha suerte :)
