As part of our Science rotation this week, Room 2 along with 3 other classes has been studying the Living World with Whaea Paula. Last week we planted stir fry bean seeds and radishes and this week we tested the soil to see if they were acidic or alkaline. Believe it or not we used red cabbage dropped into boiled water, dribbled vinegar into the mix and then, when it cooled, placed a sample of soil into it. Some mixtures turned red, others stayed purple and others, well they just looked plain dirty….. From this experiment we learned that if the water stayed purple it was alkaline, if it turned red, it was acid……Apparently it is ideal for an indoor plant’s soil to be a little acidic. The dirty soil, well I think someone just got a little carried away perhaps? Our next step is decide what we can do if our soil is alkaline. I wonder what will happen in our next lesson?
