Chemistry - Grade 11

Length: Full year Grade: 11th Grade Required Science

Course Description

Can we change any material into gold? What properties do elements have and how can they vary? What gives molecules their smells, reactivities, and elemental ratios? What causes our weather and how can we model weather phenomenon using gas laws. How do toxins impact our bodies and the environment? In chemistry we study the world from a molecular perspective, with the goal of understanding how interactions between atoms and molecules lead to macro-scale observable phenomenon in our world. Through lab work, guided inquiry, and class discussion we build a comprehensive knowledge of the fundamentals of chemistry.

Enduring Understandings

• The periodic table is a systemic way of categorizing properties of atoms and elements.   

• Chemical and nuclear changes lead to new materials with new properties.  

• The structure of individual atoms regulates how they interact with other atoms.    

• Our bodies have mechanisms to respond to a variety of chemicals based on their structure . 

• The weather is driven by pressure differences in atmospheric gases. 

• The concentration and toxicity of materials determines their impacts on organisms and ecosystems. 

Essential Questions

• Can we make gold from other materials? 

• What helps us smell? How can we differentiate between chemicals with our noses? 

• What causes the weather? 

• How can we decide if a chemical is toxic? 

• How does energy move between systems?
