10 Classroom Resources
-
Activity | Atomic Theory, Law of Conservation of Energy | High School
Simulation Actvity: Exciting Electrons
In this simulation, students will explore what happens when electrons within a generic atom are excited from their ground state. This is a qualitative investigation, not meant to mimic any particular atom.
-
Activity | Heating Curve | High School, Middle School
Simulation Activity: Heating Curve of Water
In this simulation, students will investigate qualitatively and quantitatively what happens as water changes states.
-
Simulation | Molecular Motion | High School, Middle School
Molecular Motion
In this simulation, students will have the opportunity to explore on the molecular level how particles move in three states of matter. They will compare two different substances.
-
Activity | Covalent Bonding, Ionic Bonding, Molecular Formula | High School, Middle School
Simulation Activity: Ionic and Covalent Bonding
In this simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. The simulation visually differentiates between the transferring of electrons when forming an ionic compound and the sharing of electrons when forming a covalent compound so that students can have a complete understanding of each. Finally, students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.
-
Activity | Atomic Radius, Ionic Radius, Ionization Energy, Periodic Table, Valence Electrons | High School
Periodic Trends I: Ionization Energy, Atomic Radius & Ionic Radius
In this simulation, students will investigate several periodic trends, including atomic radius, ionization energy and ionic radius. Through the use of this simulation students will have the opportunity to examine atomic data as well as visually compare and interact with select elements from the periodic table.
-
Activity | Atomic Radius, Electron Affinity, Ionic Radius, Periodic Table | High School
Periodic Trends II: Electron Affinity, Atomic Radius, & Ionic Radius
In this simulation, students will focus their investigation on the electron affinity of an atom. Through the use of this simulation students will have the opportunity to examine the formation of an anion as well as compare the atomic radius of a neutral atom to the ionic radius of its anion.
-
Activity | Gas Laws, Rate of Effusion | High School
Gas Laws
In this activity, students will examine gas laws by carrying out several computer simulations.
-
Lab | Density, Molecular Motion | High School, Middle School
Density Lab
In this lab, students determine the density of several liquids and solids. They then identify an unknown metal by determining its density. They then calculate the percent error within the class for a specific sample.
-
Simulation | Atomic Theory, Model of the Atom, Subatomic Particles | High School, Middle School
Building an Atom
In this simulation, students manipulate the number of protons, neutrons, and electrons in an element and determine how these effect the mass number, atomic number, and other properties of an atom.

Lesson Plan | Gas Laws | High School
The Gas Laws 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 Gas Laws to your students.
