Spring 1
In Science, Class 3 have been exploring plants and their life cycle. The children learned about the main stages of a flowering plant’s life and why the roots are so important to its survival. The children also investiagted photosynthesis and what ingredients are needed for this fascinating chemical reaction to take place: water, carbon dioxide and sunlight! The children compared two plants – both had been given water and carbon dioxide – but one had been restricted of sunlight and placed in a dark cupboard. The children were amazed to see what effect this had on the plant! Its leaves had weakened and dried and the plant just didn’t look healthy or well at all because it was unable to create its own food. We have also explored seed dispersal and will be finalising that learning immediately after half term.
Autumn 2
Class 3 have been learning all about states of matter – solids, liquids and gases. We have talked about the molecules in each state and how they behave and then thought about: ‘What is air?’ Hmmmm… this really got our brains thinking! Does air have weight? So, we carried out an investigation to see if it does. We used two balloons and a coat hanger as a set of scales to compare a balloon filled with air and one that was empty. Although the difference was slight, we could see the filled balloon was indeed heavier – so air does weight something!
Autumn 1
In Science, we have been exploring the human digestive system including teeth and we had the chance to compare human teeth to that of herbivores and carnivores and conduct a crazy investigation to explore the effects of fruit juices, cola, water and milk on our teeth (although we used marble chips instead of our precious teeth to experiment with)!
