Intermolecular Forces and Density Practice Set for High School Chemistry
A scaffolded practice packet for 10th graders that builds understanding of intermolecular and intramolecular forces, with a visual glossary, investigation planning on melting point, viscosity, solubility, and conductivity, and worked density problems linking mass and volume. It includes vocabulary and mathematical support, making it well suited to a multi-day review block or small-group work where students justify their claims with evidence.
“Please develop a scaffolded review regarding these standards: construct an argument by applying principles of inter- and intra- molecular forces to identify substances based on their chemical and physical properties; plan and carry out an investigation to gather evidence to compare the physical and chemical properties of matter at the macroscopic scale to infer the strength of intermolecular and intramolecular forces (Clarification Statement: The investigation may include melting point, state of matter, solubility, viscosity, and conductivity.); plan and carry out an investigation about the physical and chemical properties of matter at the macroscopic scale; use mathematical and computational thinking to solve density problems and understand the relationship between density, mass and volume. Please include vocabulary support and mathematical support.”
Teacher Guide & Tips
- Introduce the Visual Glossary first so students can sketch each force (ionic, covalent, hydrogen bonding, dipole-dipole, London dispersion) before tackling the evidence tasks, which typically takes about 15 minutes.
- Discussion question: How would a substance's melting point change if its intermolecular forces were stronger, and what evidence from the investigation would support that claim?
- Scaffold for struggling readers: Pair each density problem with a completed example and a labeled formula triangle (D = m/V), and have students annotate key vocabulary before answering the constructed-response questions.
- Extension for advanced students: Ask them to predict the conductivity or viscosity of an unfamiliar compound from its molecular structure and design a controlled test to confirm or refute the prediction.
- Estimated time: Plan roughly 60 to 90 minutes across one or two class periods, depending on whether the investigation is carried out in full or only planned.
