Phase Change Game

In the Phase Change game, players match the sequence of phases in each target by adding or removing energy to affect particle motion and IMFs.

Watch this clip from our Phase Change game webinar to see the Phase Change game in action!  Or you can view the full webinar here.

Core levels

Player adds an F atom to build a non-polar CF4

Players must heat or cool particles by adding or removing energy to satisfy the phase change of the targets.

non-polar CF4 resulting in LDFs and a polar CH2F2 resulting in dipole-dipole interactions

Players will break or form IMFs between particles during a phase change. The stronger the IMF, the more energy required to break it.

Players will observe that phase changes occur at a constant temperature.

Connected levels

Intermolecular Forces & Phase Change

In these connected levels, there are molecules missing from the bank. Players must return to the IMFs game to build the molecules that they need in order to match the sequence of phases in each target.

Players must build molecules in the Intermolecular Forces game that have IMFs that allow for the phase change needed to correctly match the targets. Players are prompted to think about how IMF strength affects the amount of energy released or used during the breaking and forming of IMFs during phase change. The stronger the IMFs, the more energy released when forming these IMFs.
Ionic Bonding & Phase Change

In these connected levels, there are ionic compounds missing from the bank. Players must return to the Ionic Bonding game to build the ionic compounds that they need in order to match the sequence of phases in each target.

Players must build and send ionic compounds that can be used in the phase change game given the energy provided. Once built, players can send these compounds through the pipe, heat or cool the compound, and break or form ionic bonds to change phases and satisfy the target.

Sandbox

The Sandbox is an open-ended and exploratory environment designed for students to freely explore phase change using the provided bank of particles. Complement your instruction by designing your own Sandbox activities and encourage your students to earn the built-in Achievements that focus on a specific topic within Phase Change (i.e. type of phase change, energy and phase change, IMFs and boiling point).
