• Intermolecular Forces, Solubility, Intermolecular Forces, Intramolecular Forces, Polarity, Lewis Structures, Molecular Structure, Solute & Solvent, Mixtures, Melting Point, Freezing Point, Boiling Point, Physical Properties, Graphing, Mixtures | High School

### Access is an AACT member benefit. Lab: Physical Properties (High School)

In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

• Solubility, Solute & Solvent, Physical Change, Molecular Motion, Phase Changes, Reaction Rate | Elementary School

### Access is an AACT member benefit. Lesson Plan: Particles in Motion

In this lesson, students learn that particles that make up matter are in constant motion.

• Entropy, Kinetic Molecular Theory, Molecular Motion, Intermolecular Forces, Density, Volume | High School

### Activity: Connecting States to Entropy

In this activity, students use blocks to model different states of matter and the Kinetic Molecular Theory to understand the concept of entropy. This is a concept mandated by SAT level or AP level high school chemistry class.

• Phase Changes, Physical Change, Observations, Temperature | Elementary School, Middle School

### Access is an AACT member benefit. Lab: Condensation

In this lab, students will explore the process of condensation. Students will investigate how water vapor condenses, and then they will conduct a comparison test to see if cooling water vapor has an effect on the rate of condensation.

• Colligative Properties, Boiling Point, Molality, Concentration, Boiling Point Elevation, Graphing, Accuracy, Physical Properties, Error Analysis | High School

### Access is an AACT member benefit. Lab: Changing Water's Boiling Point

In this lab, students will explore colligative properties in a quantitative approach. They will measure the effect of increasing the molality of a salt solution on the solution’s boiling point, and they will graph their data and use the slope of the line of best fit to calculate the boiling point elevation constant of water. There are three versions of the lab, some of which provide more structure and guidance and others of which are more student-driven.

• Physical Change, Chemical Change, Solute & Solvent, Observations, Inferences, Physical Change, Identifying an Unknown | Elementary School

### Access is an AACT member benefit. Lesson Plan: Alien Invasion?

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.

• Observations, Combustion, Phase Changes, Experimental Design, Scientific Method | High School, Middle School

### Access is an AACT member benefit. Lab: Observing a Candle

In this lab, students accumulate observations of a candle including a look at the combustion reaction's reactants and products.

• Mixtures, Physical Change, Physical Change, Solute & Solvent, Phase Changes, Distillation, Introduction, Separating Mixtures, Interdisciplinary, Mixtures | Elementary School

### Access is an AACT member benefit. Lesson Plan: Now I Can Drink the Water!

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).

• Melting Point, Elements, Matter, Density, Chemical Properties, Periodic Table, Inferences | Elementary School

### Access is an AACT member benefit. Lesson Plan: Mystery Metals

In this lesson, students will make measurements, calculations, and inferences to help solve a mystery about the identity of an unknown metal.

### Simulation: Heating Curve of Water

In the May 2015 issue, students explore the heating curve for water from a qualitative and quantitative perspective. Students compare illustrations of each physical state depicted on the curve and calculate the energy required to transition from one state to another.

• Intermolecular Forces, Polarity, Molecular Motion, Intermolecular Forces, Molecular Motion, Physical Change, Physical Change | High School

### Simulation: Comparing Attractive 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).
