This morning Marcos and I reviewed questions 1-21 on pages 92-93 in order to complete our exploration of physical and chemical change. We debated whether or not scrambled eggs constitute a physical versus a chemical change whereby we exchanged compelling arguments in support of both. We started the next chapter which focuses on the atom and essentially what makes matter. We had a brief discussion surrounding several early scientists comparing their ideas as to what matter was actually made of. Homework is to read pages 98-104.
