Classroom Resources: States of Matter
1 – 4 of 4 Classroom Resources
Physical Change, Intermolecular Forces, Polarity, Physical Change, Molecular Motion, Molecular Motion, Intermolecular Forces
In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
Observations, Chemical Change, Physical Change, Inferences, Physical Change, Identifying an Unknown, Solute & Solvent | Elementary School
In this lesson, students will explore both physical and chemical changes as they try to help the Department of Homeland Security analyze and identify materials found in a mysterious capsule. Students will examine and observe an unknown object (a frozen water balloon) as it changes (melts). They then mix combinations of everyday substances to observe chemical changes.
Separating Mixtures, Mixtures, Physical Change, Physical Change, Phase Changes, Introduction, Interdisciplinary, Distillation, Solute & Solvent, Mixtures | Elementary School
In this lesson, students review important concepts of the water cycle and then design, test, and evaluate a working model of a desalination plant (a distiller).
Solubility, Physical Change, Phase Changes, Reaction Rate, Solute & Solvent, Molecular Motion | Elementary School
In this lesson, students learn that particles that make up matter are in constant motion.
