Create water and carbondioxide molecules

1 collaborator

WHAT IS IT?

This model shows different atoms (Oxygen (symbol O and color red), Hydrogen (symbol H and color white), and Carbon (symbol C and color grey)) then these atoms are combined to form two different types of molecules (H20-water and CO2-carbondioxide).

HOW TO USE IT

Click set up to start. Click create atoms to create three different atoms that move randomly in the world. To create water or carbondioxide molecule click the corresponding button. Use a speed model that is less than normal speed to see the atoms and molecules movement.

THINGS TO NOTICE

Notice the different color combinations for each molecule.

THINGS TO TRY

Try to click as many times the create water or carbondioxide button to show the formation of new molecules.

EXTENDING THE MODEL

This model can be extended to include more atoms and more molecules.
