Incident Report

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.
