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. Data When asked what is data, we were not very sure. So to help us understand data Ms Smita gave us a challenge. We were to make as many interlocked loops as possible within three minutes! We took on the challenge and put our fine motor skills to work! Once we made our loop chains we wanted to compare how long each one was. So we all had to start placing our chains at the same starting point. We then realised that we had to label each loop to identify whose loop it was. Once that was done we compared whose was longer, shorter or the same. We also compared the chains to find out if they were same, longer or shorter. On another day we collected data about our shoes. We sorted the shoe in to different categories. To make it easier to count we drew lines between each shoe (which looked like a grid). This helped us view and read the data easily. EEKK! We were introduced to EEKK! Here we 'Read to Someone' and then check for understanding. Metal detector! Zoe's daddy came to show us how people use the metal detector to find metal. When the detector came across any metal it went beep beep beep! We went to look for some hidden treasure in our sandpit using the metal detector. It was so much fun! People use it to find treasure! Zoe's daddy then read us a story by Dr Suess! We like when mummies or daddies come to read to our friends.
Superheros! We were given the opportunity to be Superheros! Our mission was to fly to save the people on the other side of the white line and get them back! We had to be fast! So we set out on our rescue mission wearing a mask and a cape. But then the capes were made of different materials! We had to test which was the most suitable material for a cape. It had to be light, not make any noise and help us fly fast. After testing capes made of wood, plastic, fabric and metal we came to the conclusion that fabric was best suited for a cape! Waterproof or absorbent? Ms Smita sprayed lots of water on us. But we did not get wet! We were wearing our rain coats/ carrying an umbrella. We found that umbrella/rain coat is made of a material that does not let water go through it and it is waterproof. But Ms Smita did not stop at that! When we put away our umbrellas/raincoats she sprayed water on us again. We were 'soaked'! We thus found out that clothes (fabric) absorb or soaks water. Exploring another material: CLAY It is a natural material. It is soft, smooth, mushy, cold and can be moulded into different shapes. It becomes hard when it is dry. It can break when it is dry. When heated and cooled it becomes waterproof. We can use it to make pottery- glass, tea pot, mugs, bowls and also make sculpture. 3D Shapes all round us!
We used recyclable materials to make 3D images! |
