||'''Slide Number 1'''

'''Title Slide'''
|| Welcome to this Spoken Tutorial on '''Build a Molecule'''.

|-
||'''Slide Number 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn how to:
* Build molecules from atoms.
* Build molecules using a chemical formula.

|-
||'''Slide Number 3'''

'''System Requirements'''
|| This tutorial is recorded using,

macOS Catalina version 10.15.7

Google Chrome version 101.0.49
|-
||'''Slide Number 4'''

'''Pre-requisites'''

'''https://spoken-tutorial.org'''

|| To follow this tutorial,

Learners should be familiar with topics in basic chemistry.

Please use the link below to access the tutorials on '''PhET simulations'''.

|-
||'''Slide Number 5'''

Link for '''PhET simulation'''.

'''https://phet.colorado.edu/sims/html/build-a-molecule'''

|| Please use the given link to download the '''PhET simulation'''.
|-
||'''Slide Number 6'''

'''PhET Simulation'''

|| In this tutorial, we will use,

'''Build a Molecule PhET simulation'''.
|-
||Point to the simulation in the '''Downloads''' folder

'''Build a Molecule simulation'''.
|| I have already downloaded the '''simulation''' to my '''Downloads''' folder.
|-
||Double click on the '''build-a-molecule_en.html''' file.

Show in the browser.
|| 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.

Click the mic icon.
|| This is the interface of the '''Build a Molecule''' simulation.

You can adjust the simulation volume at the bottom right of the screen.

|-
||Point to each screen.
|| The interface has three screens,

'''Single''',''' Multiple''', and '''Playground'''.

|-
||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.

We can use the arrows on both sides of this box to access the other atoms.

We can drag the atoms in the containers onto the screen to build molecules.

|-
||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.

Otherwise it will put the unused atoms on the screen back into the containers.

|-
||Point to '''Your Molecules''' table.

Point to the list of molecules.

Point to the '''Reset''' button.

Point to the '''Reset ''' button.
|| On the right, we have the '''Your Molecules''' table.

It has a list of molecules that we have to build and collect.

It has a small '''Reset''' button at the bottom.

It will put back all the used atoms into the containers.

|-
||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.

We will use these to build molecules.

Molecules are neutral particles made by the bonding of two or more atoms.

|-
||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.

Point to the water molecule.
|| If we bring the three atoms close, they get attached to each other.

A water ( H2O) molecule is formed.

|-
||Click the green '''3D''' button.

Point to '''space fill''' and '''ball and stick''' options.

Click on '''Ball and stick''' option.
|| The green '''3D''' button shows the molecule in 3D format in a new window.

At the bottom of the window we have '''spacefill''' and '''ball and stick''' options.

We can choose to show the molecule either in '''spacefill''' or '''ball and stick''' format.

|-
||Click on the cross mark.
|| Let us close the window.

|-
||Click on the blue cross button above the molecule

Drag all atoms close again.

|| 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.

Click on the '''Next Collection''' button on the dialog box.

|| A dialog box appears after completing this collection of five molecules.

Click on the''' Next Collection''' button to start building more 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.

It is similar to the '''Single''' 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.

Drag the molecular hydrogen in the box.

|| Let us make '''molecular hydrogen''' and put it in the table.
|-
||Point to the '''Your Molecules''' tables.

Point to the 4 H2 molecules.

Point to other molecules in the table.
|| Here the goal is to make '''4 H2 '''molecules and we have made only one.

You can complete the remaining collection on your own.

Similarly build the other molecules and place them in the table.

|-
||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 X icon to close.
|| Click the '''3D''' button to show its 3D structure.

Let us close the window.

|-
||'''Slide Number 7'''

'''Assignment'''

Use the '''Playground''' screen to build the following molecules:

* Hydrogen cyanide
* Chloromethane
* Nitric oxide
* Methylsilane
* Phosphine
* Hydrogen bromide

|| As an assignment,

Use the '''Playground''' screen to build the following molecules.

|-
||
|| With this, we have come to the end of this tutorial.

Let us summarise.
|-
||'''Slide number 8'''

'''Summary'''
|| In this tutorial, we have learnt how to:
* Build molecules from atoms.
* Build molecules using a chemical formula.
