Heat changes materials! This week Anjali and Ashritha's mummy came to our class to conduct some experiments. We wanted to find out how heat would change the material. She brought a 'Bunsen Burner'. There were two types of flame that came out from it. The yellow flame that went high up was not the best to heat objects. The blue flame generated more heat was better to heat objects. We had thought of many things that could happen to the materials when heated. It could Melt Burn Bend Evaporate Harden Before subjecting the object to heat we had to make hypothesis of what would happen to the object. Then Dr Jeremiah, conducted the experiments. Most of our hypothesis were right! When subjecting glass to heat Zoe said that she had seen that 2 pieces of glass could join when heated. We could not do that experiment because it needed a very high temperature! This lead us to our investigation on glass. We watched a video on how glass was shaped when heated. We also saw that some glass was transparent. And that lead to our next inquiry about finding which objects were transparent, translucent and opaque. Transparent: We noticed that light goes through an object when it is transparent. The shadow cast is only of the outline of the object. Translucent: Here we noticed that some line passes through the object and we cannot see clearly through it. The shadow cast by objects that are translucent is also translucent. Some light goes through it, but the outline is not as defined as that of a transparent object. Opaque: Light could not pass through these objects. The shadows were just like that of the object. Math
When we combine two groups of objects they become more. There are lots of words to describe that put together sum add combine join total plus We made our own stories problems, which we represented using manipulatives, drawings and number sentence.
