Visual Cue Narration
Slide Number 1

Title Slide

Welcome to this tutorial on Build an Atom simulation.
Slide Number 2

Learning Objectives

In this tutorial we will,

Demonstrate Build an Atom, Interactive PhET simulation.

Slide Number 3

Pre-requisites

To follow this tutorial,

Learners should be familiar with topics in high school science.

Slide Number 4

System Requirement

Here I am using-

Ubuntu Linux OS version 14.04

Java version 1.7.0

Firefox Web Browser Version 53.02.2.

Slide Number 5

Learning Goals

Using this Simulation, Students will be able to-

Build an atom using protons, neutrons and electrons.

Identify an element and its position on the periodic table.

Determine whether an atom is neutral or an ion.

Predict the charge.

Slide Number 6

Learning Goals

Determine the mass of an atom or ion.

Determine the stability of atom or ion created.

Represent the atomic symbols.

Create Isotopes of an element.

Slide Number 7

Composition Of An Atom

Atoms are fundamental building blocks of matter.

Each atom consists of a small, dense, positively-charged nucleus.

Nucleus is surrounded by much lighter, negatively-charged electrons.

Slide Number 8

Composition Of An Atom

Nucleus may also contain neutrons.

Neutron has same mass as proton but it has no charge.

Slide Number 9

About Atom

Number of protons in the nucleus of an atom defines the chemical element.

Chemical properties of an element arise due to number & arrangement of electrons.

Let us get started.
Slide Number 10

Link for PhET simulation

http://phet.colorado.edu/

Use the given link to download the simulation.

http://phet.colorado.edu

Point to the file in Downloads folder. I have already downloaded, Build an Atom simulation to my Downloads folder.

Cursor on the Interface. This is the Interface of Build-an-Atom simulation.
Point to the three screens. The interface has 3 screens,

Atom,

Symbol and

Game.

Point to Atom screen.

Click on Atom screen.

Let us begin our simulation with Atom screen.

Click on Atom screen.

Using this screen students can-

build atoms,

determine the identity,

net-charge and

mass of an atom.

Pointer on the Atom drawing.

Point to the nucleus.

Point to orbits.

Point to the three containers.

Atom screen shows a Bohr's model of an atom.

It shows position of nucleus and 2 orbits.

At the bottom of the screen there are 3 containers with,

Protons

Neutrons and

Electrons.

Point towards boxes naming Element, Net charge and Mass Number.


On the right-side, there are 3 panels,

Element,

Net charge and

Mass Number.

Click on the green plus sign located on each box. To open the panel,

Click on the green plus sign located on top-right corner on each panel.

This allows you to view the changes as you change the number of particles.

Point to Show box.

Click on Stable/Unstable check box.

At the bottom of the screen, you will see Show box.

In the box, click on Stable/Unstable check box.

Point to box.

Point to Protons, Neutrons and Electrons.

The top left corner of the screen shows a box.

It shows-

The number of Protons, Neutrons and Electrons we have used to create the atom.

Click on the Proton.

Drag and drop on the X mark.

Let us start by building Hydrogen atom.

From the Proton container, click on the Proton.

Drag and drop on the X mark, which represents the nucleus of an atom.

Point to the boxes on the panel. Simultaneously observe the changes in each of the panels.
Cursor on the panel. Hydrogen atom is the simplest of all elements.

It has one electron in the first orbit and one proton in the nucleus.

Drag an Electron and place in the 1st orbit.

Point to circular dashed lines.

Drag an Electron and place in the 1st orbit.

By default the orbits are shown as circular dashed lines.

Under Model heading, click on Cloud radio button.

Point to orbit.

Click on Orbits radio button.

Under Model heading, click on Cloud radio button.

This will show the orbit as electron cloud.

Click on Orbits radio button to show the default orbits.

Point to the boxes on the panel.

Point to Hydrogen.

Point to Net charge.

Point to Mass number.

Observe all the panels on the screen.

Element box shows Hydrogen as Element.

Net charge is zero and is labeled as neutral atom.

Mass number is one.

Point to Stable. It also shows that, the atom is Stable.
Drag a Proton and place it on the nucleus.

Point to Helium Ion.

Now add one more Proton to the nucleus.

The atom is shown as Unstable Helium Ion.

Drag an Electron and place it on the 1st orbit.

Point to Unstable label.

Add one more Electron in the 1st orbit.

Now it is a Neutral atom, but the atom is still labeled as Unstable.

Drag a Neutron and place it on the nucleus.

Point to the Mass Number.

Drag a Neutron and place it on the nucleus.

Add a Neutron to the nucleus. The atom is now Stable.

The Mass Number shows 3, but we know that atomic mass of helium is 4.

So add another Neutron to the nucleus.

This completes the atomic structure of Helium atom.

Point to Protons, Neutrons and Electrons. Helium atom has 2 Protons, 2 Neutrons and 2 Electrons.
Point to the model. We can add Neutrons to the nucleus to create isotopes of the same element.
Slide number 11

Isotopes

Atoms of the same element that differ in neutrons are called Isotopes.

Isotopes of same element have same chemical properties.

Drag and drop one Proton, one Electron and 2 Neutrons from the Helium atom. Remove one Proton, one Electron and 2 Neutrons from the Helium atom.

Now we have hydrogen atom also called Protium.

Cursor on the window. Let us create Isotopes of Hydrogen.
Slide Number 12

Isotopes of Hydrogen

Hydrogen has three isotopes.

Protium, Deuterium and Tritium.

Nucleus of Protium contains only one Proton.

Deuterium has one Proton and one Neutron.

Tritium has one Proton and 2 Neutrons.

Drag and drop one Neutron to the nucleus.

Point to atom.

Point to Stable.

Drag and drop one more Neutron to the nucleus.

Point to atom.

Add one Neutron to the nucleus.

Deuterium atom is created.

It is Stable.

Add another Neutron to the nucleus to create tritium.

Tritium is unstable, as shown here.

Slide number 13

Assignment

As an assignment,

Create a neutral carbon atom.

Show isotopes of carbon.

Click on the reset button. Click on reset button at the bottom-right corner.

This will reset the screen to default settings.

Click on Symbol screen at the bottom of the screen. Next click on Symbol screen at the bottom of the interface.

Using this screen, students can interpret atomic symbols.

Cursor on Symbol screen. Notice that a Symbol panel is added on the screen.

Atom of every element is represented by a symbol.

It gives information about atomic number, mass number and charge.

Point to subscript number.

Point to superscript number

Point to top right corner number.

The subscript number is called the atomic number.

The superscript number is called the mass number.

Charge on the atom is shown on the top-right corner.

Slide number 14

Atomic Number and Mass Number

The number of protons in an atom is its atomic number.

The total number of protons and neutrons in an atom is its mass number.

Drag and drop Protons, Neutrons and Electrons to the atom.

Cursor on the Symbol panel.

Point to Element, atomic number, Mass Number and charge.

Add Protons, Neutrons and Electrons to the atom.

Observe the Symbol panel.

Note the change in name of Element, atomic number, Mass Number and charge.

Point to Game screen.

Click on Game screen.

Point to the games.

Now we will move on to the Game screen.

Click on Game screen at the bottom of the interface.

Four different games are available.

These games will test the knowledge gained using this simulation.

Point to timer and sound button.

Click on timer button.

Click on sound Symbol.

A timer and a sound button are provided at the bottom-left corner of the screen.

Click on the timer button to enable the timer before the game starts.

We can also control the sound by clicking on the sound symbol.

Click on each game screen. Click on each game screen and explore.
