    **Use** this guide to help you complete the PhET simulation: States of Matter.

    ### Simulation

    **Visit** the
    [States of Matter: Basics simulation](https://phet.colorado.edu/sims/html/states-of-matter-basics/latest/states-of-matter-basics_en.html) and then
    **complete** the following steps.

    Click the play button on the first page of the simulation.

    ![First page of States of Matter: Basics simulation showing where the play button is located](https://www.sweetstudy.com/questions/wk-1-phet-simulation-and-observation-guide)

    Click on the
    **States** icon from the States of Matter: Basics home screen.

    ### Connecting Ideas

    Now that you have explored water as a solid, liquid, and gas, let’s think about how these ideas support some chemistry concepts.

    The learning goal for this week is: Classify matter, including its physical and chemical properties, the structure of atoms, and the relationships between elements as organized in the Periodic Table of Elements. Use what you know about the learning goal and respond to the following prompts:

    · Identify which parts of the learning goal you explored in this PhET observation guide.

    · Which parts of the learning goal were not addressed in this observation guide?

    · In 2-3 sentences, explain what you learned about classifying matter, including physical and chemical properties, from this observation guide.

    To: [Insert the audience for the incident report. You should use your training officer’s name.]

    From: [Insert your name and title. Since you are submitting the incident report, use your name and a fictitious position.]

    Date: [Insert the date.]

    Purpose: [Explain the incident by classifying matter, including its physical and chemical properties, the structure of atoms, and the relationships between elements as organized in the Periodic Table of Elements.]

    #### Observation and Explanations Table

    **Complete** the table according to the following guidelines:

    · Row 1 is provided as an example of how to complete the remainder of the table.

    · Column 1: What was Observed: This has been provided for you.

    · Column 2: Component of Matter Classification Used to Explain: This has been provided for you.

    Column 3: Explanation: Write a minimum 3-sentence explanation using a minimum of 2 vocabulary words for each of the following:

    · Classify matter, including its physical and chemical properties

    · The structure of atoms

    · The relationships between elements as organized in the Periodic Table of Elements

    · Column 4: Supporting Information from at least one PhET simulation: Review your notes from the PhET simulations and write a 2- to 3-sentence response about why your observations in the simulation support your explanation of the classification of matter for each of the observations.

    | | | | | |
    | — | — | — | — | — |
    | | Column 1: What was Observed | Column 2: Component of Matter Classification Used to Explain | Column 3: Explanation | Column 4: Supporting Information from the PhET |
    | Row 1 | Example: The pile of metal shavings, a pool of clear liquid, and a white residue on the ground | Example: physical and chemical properties | Example: The metal shavings represent a solid substance, the clear liquid could be a solvent or reactant, and the white residue suggests a chemical reaction has taken place, forming a new substance. Physical properties describe the state of matter and appearance, while chemical properties explain the formation of new substances through reactions. | Example: In the States of Matter simulation, we could see different properties of states of matter. When materials are in their solid phase, they hold their own shape like the shavings of metal in the pile. When liquid, substances fill their containers or become flat on the ground like the clear pile of liquid. Changes to states of matter can be caused by temperature changes. In the simulation, we saw the atomic structure of a solid change to a liquid when we held the fire below it for long enough. If we kept increasing the temperature, we could see the liquid become a gas. |
    | Row 2 | The pile of metal shavings is magnetic | the relationship between elements as organized on the Periodic Table of Elements | | |
    | Row 3 | The liquid had evaporated and left salt fragments behind | physical and chemical properties | | |
    | Row 4 | A white residue that is neither solid nor liquid, rather a gas that has condensed into a thin film | physical and chemical properties | | |
    | Row 5 | Using a portable meter, the presence of carbon and oxygen atoms are found | the structure of atoms and the relationship between elements as organized on the Periodic Table of Elements | | |

    #### Summary

    **Write** a 3- to 5-sentence summary that addresses how the classification of matter, including its physical and chemical properties, the structure of atoms, and the relationships between elements as organized in the Periodic Table of Elements helped understand the incident.

    Click on the
    **Atom** icon from the Build an Atom home screen.

    1. You will arrive at this page.

    ![A screenshot of the Build an Atom simulation once the Atom icon has been selected. The page shows the Periodic Table in the upper right corner. There are 3 bowls at the bottom of the screen one for each, protons, neutrons, and electrons](https://www.sweetstudy.com/questions/chemistry-20985791)

    Click and drag 1 proton into the nucleus, which is marked by the X. What element is created by adding 1 proton?

    Add 4 more protons so that there are 5 total protons in the nucleus. What element is created when there are 5 protons?

    Predict the stability of your element. Next click the radio button next to Stable/Unstable to see if your prediction was correct. What did you predict? What does the stable/unstable box show?

    Click on the Net Charge + sign.

    ![Image of simulation showing where the Net Charge + area is located.](https://www.sweetstudy.com/questions/chemistry-20985791)

    The Net Charge box will expand. Next, begin adding electrons to the diagram.

    ![A screenshot of the Build an Atom Simulation once Net Charge has been selected. The Periodic table is located in the upper right corner and the Net Charge meter is below the Periodic Table.](https://www.sweetstudy.com/questions/chemistry-20985791)

    Add electrons to the diagram until the net charge becomes 0. How many electrons were added to reach a net charge of 0?

    Add neutrons until your created element becomes stable. How many neutrons were added to create a stable atom?

    You now have 5 protons, 5 neutrons, and 5 electrons. What type of atom have you created?

    Now it is your turn to have some fun! Build an atom of your choice. How many protons, neutrons, and electrons are in your atom? What is the name of the atom you created? Record your findings:

    Number of protons:

    Number of neutrons:

    Number of electrons:

    Name of atoms:

    ### Connecting Ideas

    Now that you have explored atoms, protons, and neutrons, let’s think about how these ideas support some chemistry concepts.

    The learning goal for this week is: Classify matter, including its physical and chemical properties, the structure of atoms, and the relationships between elements as organized in the Periodic Table of Elements. Use what you know about the learning goal and respond to the following prompts:

    · Identify which parts of the learning goal you explored in this PhET observation guide.

    · Which parts of the learning goal were not addressed in this observation guide?

    · In 2-3 sentences, explain what you learned about the structure of atoms from this observation guide.

    · In 2-3 sentences, explain what you learned about the relationships between elements as organized in the period table. (If you are unsure, return to the PhET simulation and look for patterns as you build different atoms.)
