Not hands-on in my opinion, but a great way to show the correlation between periods and energy levels. Also, a great way to introduce Lewis dot diagrams: "just cover up the inner electrons". I like how there's room for the student to draw their own diagrams for the lower p-block elements. It allows them to identify trends and predict configurations.
