Science experiments for children – The juice of red cabbage: experiments to find out if the substances are acidic, basic or neutral using the juice of red cabbage (to learn more, go the post http://www.lapappadolce.net/en/science-experiments-for-children-measure-the-ph-with-red-cabbage/):
Pouring the juice of red cabbage in many different bowls, and placing them on a sheet of paper, children can test various substances, record them on the sheet, and write in the notebook their observations:
You can test many substances found in the home: salt, toothpaste, bleach, ammonia, lemon juice, fruit juices, sugar, spray for glasses, dish soap, etc…
The various substances tested can be classified and ordered from most acidic to most basic…
bella esperienza da proporre, grazie! non mi è chiaro però che colorazione assume il cavolo in base all’acidità o basicità delle sostanze testate, potrebbe spiegarlo?
Grazie mille
Avremo rosso nelle soluzioni più acide, viola-blu in quelle poco acide, verde nelle poco basiche, giallo nelle più basiche
