Is didi smarter?

I was going through Tessa's science assessment today. She told me she could not answer some of the questions. One of them asked about common characteristics between a Tree and a Tiger. She did not know what is "common characteristics". I explained to her what that meant and asked her what do both Tree and Tiger need to survive. While she was digesting my question, Jacob immediately shouted " water"! - Jacob 1 - Tessa 0

2nd question asked her to name a different characteristic between a tree and a tiger. Before she can say anything, Jacob said " Tiger can move!" Well it was obvious Tessa was not using her common sense while doing the assessment! - Jacob 2, Tessa 0

Another part of the answer to the 2nd question above talks about Tiger hunts for food while the Tree makes food through a process call?? I gave the kids a hint by saying that the word begins with photo and Jacob shouted " photosynthesis"!!! I know TELC teaches them science in k2 but I am still impressed that Jacob remembers the word! Jacob 3- Tessa 0

Is didi really smarter? We shall see next year....
