Description
This activity is designed to reinforce the concept of pure substances using models of elements, compounds, and mixtures. Students sort 20 cards on three different sorting boards. On Sorting Board 1, cards are sorted into the categories of "Pure" or "Not Pure". On Sorting Board 2, cards are sorted into the categories "Element", "Compound", or "Mixture". On the Bonus Board, students further sort the cards they have identified as mixtures into the categories "Mixture of Elements", "Mixture of Compounds", or "Mixture of Elements & Compounds". After each sort, students are prompted to complete a few questions on a record sheet to allow students to process the information they have just explored. A key is included for the teacher or the key could be used at a self-checking station for students.
