An interesting question that is very relevant to everyday life. I really like your video, which is directly related to the question and contributes greatly to the understanding . Watching the process splitting of kernels is an opportunity to look closely at a phenomenon we don`t spend a lot of time thinking about its existence .
Also, the point on the map that you specified related directly to the subject and the question. The slow motion video contributes significantly to the understanding of the subject, and can help answering the question.
It is not clear to me which topic in the curriculum the question belongs to. How can a student know the answer? Only from watching videos , it is very difficult to answer the question .
Thank you for your comment. Regarding the question, it is related to the topic "changes in matter" in eighth grade's curriculum. In the topic they learn about changes which happen in a chemical process; changes in the reactants, changes in the energy, etc...
