Description
Conflict and Cans: A Problem-Based "Periodic Table and Trends" Unit (PBL) for High School Chemistry
Summary:
Your company, Can-Do Enterprises, is a manufacturer of tin cans, steel cans with a tin-plating. Recently, one of your tin suppliers has been accused of trading in conflict resources. To avoid bad press (and bad karma), Can-Do is looking into the feasibility of changing its plating from tin to another elemental material.
See the preview for the complete introduction, a list of materials, and the first day activities.
Each file includes a classroom version of the assignment and an absent/ remote version. The absent/ remote version may require internet access but does not require any other supplies.
This product is also part of a BUNDLE found here.
Previous knowledge: physical and chemical properties, states of matter, atomic theory, basic atom anatomy
Objectives:
General:
- Construct models using Bohr's nuclear atom.
- Describe the structure of atoms and ions, including the masses, electrical charges, and locations of protons and neutrons in the nucleus and electrons in the electron cloud.
- Construct models to express the arrangement of electrons in atoms of representative elements using electron configurations and Lewis dot structures.
- Explain the development of the Periodic Table over time using evidence such as chemical and physical properties.
- Predict the properties of elements in chemical families, including alkali metals, alkaline earth metals, halogens, noble gases, and transition metals, based on valence electrons patterns using the Periodic Table.
- Analyze and interpret elemental data, including atomic radius, atomic mass, electronegativity, ionization energy, and reactivity to identify periodic trends.
NGSS:
HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS2-6. Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-ETS1-1. Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.
Contents:
Day 1:
- Introduction
- Getting to Know the Can: Cans come in many different shapes, sizes, and materials. What are the advantages and disadvantages to different types of packaging?
Day 2:
- Metals, Nonmetals, and Metalloids Lab: Hand-on. What are the physical properties of five unknown element samples? Can these properties be used to classify the samples as metals, nonmetals, or metalloids?
- Finding Metals, Nonmetals, and Metalloids on the Periodic Table Notes: How does the periodic table allow us to predict the physical properties of elements?
- Metals, Nonmetals, and Metalloids on the Periodic Table Practice: Practice
Day 3:
- Groups and Periods: How can the periodic table be used to predict the number of energy levels and valence electrons in an atom?
- Element Joke Activity: Practice
Day 4:
- Lewis Dot Structures: How do you draw a Lewis dot structure?
- Quantum Mechanical Model Introduction: How is the quantum mechanical model different from the Bohr model?
- Orbital Modeling Activity: Hands-on. What to the orbitals look like in the quantum mechanical model? How do they all fit together and hold electrons?
Day 5:
- Shady Acres Home for Grumpy Electrons Simulation: Hands-on. Why do electrons fill the energy levels and orbitals in the order that they do?

Day 9:
- Ionization Energy: Data analysis and lab. What is ionization energy?How does ionization energy predict reactivity of alkali metals and alkaline earth metals?
Day 10:
- Ionization Energy Continued: Data analysis and lab (or demo). What does ionization energy tell us about the transition metals?
