Science Instructional Plans (SIPs) help teachers align instruction with the Science Standards of Learning (SOL) by providing examples of how the content and the scientific and engineering practices found in the SOL and curriculum framework can be presented to students in the classroom.

As part of the introduction to the Periodic Table of the Elements, students will be introduced to the idea of atoms, molecules, and compounds. The physical manipulation of marshmallows (atoms) and toothpicks (bonds) will create a visual representation of the molecular structure of water. A second step requires students to create a second molecule using similar materials and using the Periodic Table as a reference point.

Students will use the periodic table to solve a riddle. Afterwards, students will choose two of the elements used in the riddle to compare their atomic structure.

This is a great activity for students to learn about elements atomic numbers. I would like to add a modification to this activity. I like to use the game, "What Am I?" In this game the students write the chemical symbol for an element on a post it note and choose another student and place it on their forehead, without them knowing what it is. When every student has a post it note on their forehead, they will walk around the class and take turns with other students giving clues to the student wearing the post it about their element. They could give clues like: number of protons, Family, period, etc.... When the student guesses his/her element, then they have 1 point. The students can collect as many points within the time frame the teacher allows.
