### Simulation: States of Matter and Phase Changes

In this simulation, students will participate in a 10 question quiz. Some questions will challenge students to analyze data to identify the correct state of matter for a specific sample, and then connect the chosen state with an animated particle diagram. In addition, students will examine the behavior of particles in an animated sample as they undergo a phase change, and must correctly identify the change that occurs.

### Lesson Plan: Phase Changes and Heat Transfer Unit Plan

The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach the Phase Changes and Heat Transfer to your students.

### Activity: Radioactive Dating: The Demise of Frosty

In this activity students will investigate the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point and then pool the data to make a graph that simulates half-life. Students will be introduced to solving mathematical problems that involve half-life.

• Phase Changes, Intermolecular Forces | High School

### Activity: The Behavior of Solids and Liquids

In this activity, students will be able to explore and explain behaviors of liquids and solids based on the individual particles in the states of matter

• Phase Changes, Molecular Motion | Middle School, High School

### Activity: Simulation Activity: States of Matter and Phase Changes

In this simulation, students will participate in a 10 question quiz. Some questions will challenge students to analyze data to identify the correct state of matter for a specific sample, and then connect the chosen state with an animated particle diagram. In addition, students will examine the behavior of particles in an animated sample as they undergo a phase change, and must correctly identify the change that occurs.

### Lab: Chemistry is Cooler Stress Test Challenge

In this lab, students will design and build a device capable of insulating an ice cube submerged in boiling water for two minutes. In this open-ended inquiry based activity, students will be required to critically think about structure and function of the materials they wish to use to build a device to solve a complex real-world problem. Students must consider the thermal properties of the materials, density, and the need to form a non-permeable barrier between the ice cube and the boiling water.

### Lab: How does Salt "Melt" Ice?

In this lab, students will consider why salt is used to aide in snow clearing and to help keep icy roads safe. They will investigate how salt ‘melts’ ice and determine the best type of salt to do so. Additionally, students will explore the advantages and disadvantages of the various different types of salt.

• Phase Changes, Elements, Mixtures | High School, Middle School

### Activity: Visualizing States of Matter
