Can you believe it is Wednesday again! Today the children all brought in a bottle of water from various sources: River, lagoon, sea, borehole, still/spring, rain and tap. We added dishwashing liquid and shook them all up - great fun ( I just made sure all the lids were on tightly) We observed how much foam each type of water made and then left them to stand for a half an hour. We observed what had happened to the foam and then determined which types of waters were 'hard' and which were 'soft'. I took photos but unfortunately they are rather shaky and unclear! Will put on my glasses next time!
