Objective

By the end of this lesson, the student will be able to understand the basics of making barista-quality coffee using a coffee machine, while also enhancing their skills in English, Math, and Science through practical application and fun activities.

Materials and Prep

• Coffee machine
• Coffee beans or ground coffee
• Water
• Measuring cup or scale
• Notebook and pen for notes
• Timer or stopwatch

Before the lesson, ensure the coffee machine is clean and ready to use. Familiarize yourself with the machine's features and settings. Prepare a comfortable workspace with all materials accessible.

Activities

• Coffee Chemistry Experiment

  Explore the science behind coffee brewing. Discuss how different temperatures and brewing times affect the flavor of coffee. Experiment by brewing coffee at different temperatures and times, then taste-test the results.

• Math Measurements Challenge

  Use a scale to measure different amounts of coffee and water for brewing. Create a graph to visualize the relationship between the coffee-to-water ratio and the resulting flavor strength. Discuss how ratios work in everyday life.

• Barista English

  Write a short essay or a script describing the process of making coffee like a barista. Include vocabulary related to coffee making, such as “extraction,” “crema,” and “froth.” Practice reading it aloud to improve pronunciation and confidence.

Talking Points

• "Did you know that the temperature of the water can really change the flavor of your coffee? Let's experiment with that!"
• "Math isn't just in the classroom; it's in your coffee cup! Ratios help us understand how much coffee to use for the best brew."
• "What do you think happens to the coffee compounds when we change the brew time? Let's taste and find out!"
• "Writing about coffee can be fun! How would you explain your favorite drink to someone who has never had coffee before?"
• "Have you ever heard of the term ‘crema’? It's the golden layer on top of an espresso shot. What do you think it adds to the drink?"
• "Let's talk about the different types of coffee drinks. Do you know the difference between an espresso, a latte, and a cappuccino?"
• "Why do you think coffee is so popular worldwide? Let's discuss its cultural significance!"
• "Did you know that the grind size of your coffee beans can affect the taste? Let’s experiment with that!"
• "What are some other beverages that use similar brewing methods? Can you think of any?"
• "How does the pressure in the coffee machine affect the brewing process? Let’s observe together!"
• "Why do you think baristas need to be skilled in both making coffee and customer service? Let's brainstorm!"
• "How can we apply what we learned today to improve our coffee-making skills? What will you try next time?"
• "What are some other scientific principles at play when brewing coffee? Let's dig deeper!"
• "How does the origin of coffee beans affect their flavor? Let’s explore some regions together!"
• "What are your thoughts on coffee sustainability? How can we make better choices?"
