Slide Number 6
PhET Simulation
|
In this tutorial, we will use,
|
Point to the simulation in the Downloads folder
|
I have already downloaded the simulation to my Downloads folder. |
Double click on the build-a-molecule_en.html file.
|
To open the simulation, double click on the build-a-molecule_en.html file.
The file opens in your default browser. |
Point to the simulation interface.
|
This is the interface of the Build a Molecule simulation.
|
Point to each screen. | The interface has three screens,
|
Click on Single screen. | Click on the Single screen. |
Point to the atoms box at the bottom. | The box at the bottom of the screen has atoms kept in containers.
|
Point to the button on the left.
Yellow/gray button with an arrow and bowl. |
The button on the left will refill the containers if atoms are used.
|
Point to Your Molecules table.
Point to the Reset button.
|
On the right, we have the Your Molecules table.
|
Point to the reset button. | The reset button will take us back to the start of the simulation.
|
Point to the atoms box at the bottom. | Atoms are single neutral particles.
|
Drag the ‘O’ atom on the screen | Let us drag the oxygen atom to the screen. |
Drag the ‘H’ atoms on the screen | Let us drag the hydrogen atoms to the screen. |
Drag all atoms close.
|
If we bring the three atoms close, they get attached to each other.
|
Click the green 3D button.
|
The green 3D button shows the molecule in 3D format in a new window.
|
Click on the cross mark. | Let us close the window.
|
Click on the blue cross button above the molecule
|
This blue button will separate the molecule into individual atoms again. |
Point to the blue arrow in the Your Molecules table. | A blue arrow appears in Your Molecules table. |
Drag the water molecule in the box next to the blue arrow | Let us drag and put the water molecule in the box next to the arrow. |
Click on the right arrow in the atoms box | We will now move rightwards in the atoms box and access the other atoms. |
Drag the ‘O’ atoms on the screen | Let us join two oxygen atoms to make molecular oxygen. |
Drag the molecular oxygen in the box next to the blue arrow | Let us drag and put the oxygen molecule in the table. |
Drag the ‘H’ atoms on the screen | Similarly let us join the hydrogen atoms to make molecular hydrogen. |
Drag the molecular hydrogen in the box next to the blue arrow | Again put the hydrogen molecule in the table as well. |
Click on the right arrow in the atoms box | We will again move rightwards to access the other atoms. |
Drag the ‘C’, ‘O’ and ‘N’ atoms on the screen | Let us join the carbon and oxygen atoms to make carbon dioxide molecule.
Also join the nitrogen atoms to make molecular nitrogen. |
Drag the molecules in the boxes next to the blue arrows | Finally, we will put these molecules in their places in the table. |
Point to the dialog box.
|
A dialog box appears after completing this collection of five molecules.
|
Point to the Your Molecules Table. | There are new atoms and molecules in this collection. |
Click on the yellow arrow at the top of the table. | Yellow arrow at the top of the table helps us to navigate between the collections. |
Point to the atoms box at the bottom. | You can practise building and collecting new molecules yourself. |
Click on the Multiple screen. | Click on the Multiple screen.
|
Point to the atoms box at the bottom. | The difference is that we have to build the same molecule multiple times. |
Drag the ‘H’ atoms on the screen.
|
Let us make molecular hydrogen and put it in the table. |
Point to the Your Molecules tables.
|
Here the goal is to make 4 H2 molecules and we have made only one.
|
Click on the Playground screen. | Click on the Playgound screen. |
Click the arrows to show various atoms at the bottom. | In this screen we can build a variety of molecules using the atoms provided. |
Drag on silicon atom and Drag 4 hydrogen atoms. | Let us build a silane molecule.
Drag a silicon atom and four hydrogen atoms. |
Click the 3D button.
|
Click the 3D button to show its 3D structure.
