1. Simulation- Gas properties

2. Unique Feature
The movement of two different types of gas
molecules are clearly shown in this simulation.
Gas properties can be determine at different
gravity level and this will increase the collision of
gas particles.
The door of the box which filled in gas can be
open to test the pressure and temperature
changes.
The force of gas particles towards the wall of box
is shown by the action of the robot icon.

3. Modeling- Masses and Spring

4. Unique Feature
Experiment can be repeated, paused, with slow
motion or stopped at any time.
Can find out the flexibility of spring at different gravity
in when the gravity is zero or even in Earth, Jupiter
and Moon.
Able to view the energy of the spring when weight is
applied to them.
Can apply the different friction on the spring to see the
differences
