In science we had been
investigating different root structures. Today we had to use our knowledge of
roots to decide whether to pull up our weeds with our hands or whether we would need to
dig down to remove the ‘tap roots’ to stop them from growing back. Aren't weeds clever?! What do you think we did with the weeds in the pictures?
Of course weeds are plants too, just growing in the wrong place for us at the
wrong time!
Once all of the stones were removed we set about adding compost. This would be the food that our plants feed on to grow strong and healthy along with plenty of sunshine and water. This was a great chance for us to talk about ‘microbes’ in science and how they help to break down ‘organic’ mater. Imagine a world with no microbes? We also had the chance to practise our measures in maths. Can you see how much soil there was in each bag? We had to do some estimating to work out how much soil we would need for all of the raised beds!
The maths didn’t stop there. Next we needed to count our seedlings (in 4’s, so a great chance to practise the 4 times table!) We then had to measure and mark out our bed to ensure that each plant had enough space to grow. In science we learned why this is important. Why do you think plants need lots of space to grow? We could fit more plants in if we squished them all together! Good idea or bad?
Once we had set all of our seedlings we had to water them
in well. We saw what happened to weeds in science if you don’t water them properly!
Like us…too much or too little is not a good idea for the long term health of a
plant!
