- Aligned with Big Idea 2 and Learning Objective 2.22
- Emphasizes Science Practices 1, 2, 3, 4, 5, 6, and 7
Explore the 4 types of bonding in solids and learn about intramolecular and intermolecular forces. Teach this activity using either the guided activity or inquiry activity. In the guided activity, students classify 12 solids as ionic solids, covalent network solids, molecular solids, or metallic solids based on properties they test. Students learn about the intramolecular forces and intermolecular forces that affect the strength of attraction between atoms.
In the inquiry activity, students test the properties of 4 solids, develop their own set of characteristics to distinguish between each bonding type, and then apply their rules to classify 8 additional solids. The inquiry activity provides an opportunity for students to present their experiment’s design and results, reinforcing the practice of communicating findings. Detailed preparation and procedure notes guide you through leading a successful inquiry exercise, including a suggested rubric for assessing student performance.
Both activities include Big Idea assessment questions that follow the format of the AP® Chemistry Exam free-response questions. In the Big Idea assessment, students apply their new knowledge of intermolecular and intramolecular forces to explain observed trends in boiling point, melting point, and solubility of substances.
This kit provides the following AP® Chemistry experiences: design a procedure to collect data, analyze data, observe physical changes, use models to explain observed results, and justify claims with evidence. The number and variety of substances tested give students a great experience developing skills of observation and analysis. Supplemental activity sheets on drawing Lewis dot structures and a periodic table of electronegativity values help students understand the spectrum of bond polarity. Materials are sufficient for 30 students working in teams of 3. Digital teacher’s manual, included FREE with kit purchase or sold separately, is a 12-month eBook license to the Types of Chemical Bonds teacher’s manual. You can also access the digital student guide for this kit for free at
