# Unit 1

Foundations of Chemistry

## Period 4 Calendar

## Period 6 Calendar

## Day 1 Stuff and Lab Safety

Objectives: Students will become familiar with the syllabus, notes structure, daily routine and classroom policies.

**Lab Safety**

Objective: Students will become familiar with the safety procedures and equipment in the classroom.

## 11.3 Atoms, Molecules and Separation Sciences

Objectives: Students will review how our model of the atom has changed overtime, apply the conservation of mass to chemical equations, and calculate mole and molarity of solutions. Students will also balance chemical equations, use stoichiometry, and determine %composition of compounds.

**Chromatography Lab (11.3)**

Objective: Students will apply chromatography to a forensic investigation

Lab Video (could be used for a virtual lab)

## 11.4 Classical Chemical Analysis

Objectives: Students will become familiar with various chemical analysis techniques and practice the calculations that go along with such analysis (such as combustion analysis, titration,etc.)

## 12.1+2 Quantum Model of the atom and Spectroscopy

**12.1+2 Quantum Model of the atom and Spectroscopy**

Objectives: Students will describe atoms in terms of the quantum model. Students will also describe the application of this model in terms of spectroscopy. Students will describe how various spectroscopy works and how it is used in forensic investigations.

## 12.3 Atomic Spectroscopy

Objectives: Students will describe various types of Atomic Spectroscopy in terms of how they work and when they are used in forensic investigations.

Helpful Videos:

AAS (short video)

AES (short video)

AFS (short video, stick to the basics and not necessarily how that particular device works)

NAA (short video, ignore the PGAA part)

## 12.4 Molecular Spectroscopy

**12.4 Molecular Spectroscopy**

Objectives: Students will describe how molecular spectroscopy works in terms of molecular orbitals. Students will describe the role of molecular spectroscopy in forensic investigations.

## 12.5 Mass Spectroscopy

**12.5 Mass Spectroscopy**

Objectives: Students will describe how a Mass Spectrometer works and its role in forensic investigations

12.5 notes (text or video (31 minutes))

2 Â˝ minute explanation of how the mass spec works

## 12.6 Radiochemical Analysis

**12.6 Radiochemical Analysis**

Objectives: Students will describe radiochemical analysis, its role in forensic investigations and do sample calculations involving radioactive isotopes.
