  • Project Helper for Grade 12 – Chemistry Project-Based Learning (PBL)

    Welcome to your very own Grade 12 – Chemistry project hub. Project-Based Learning (PBL) is a fun and engaging way to learn new things. It’s not just about listening to a teacher talk, but about exploring topics that interest you and creating projects that show what you’ve learned.

    Ask Your XTutor

    Step 1: UNDERSTAND THE LEARNING GOALS

    Your teacher will explain what you’re going to learn from the project. These goals will be connected to what you’re supposed to learn in your grade level.

    You can also read about the curriculum and skills for Grade 12 – Chemistry on the homework helper tab.

    Step 2: GET CURIOUS ABOUT A QUESTION

    During the second stage of the project you will choose a big, interesting question that your project will help answer. This question is meant to get you thinking and asking more questions. We have included 10 projects ideas as a starting point. You can discuss these ideas with your teacher as well as your XTutor before you decide on a final question.

    Project Topics and Driving Questions to Start From:

    1. Investigating Advanced Organic Synthesis: Design and perform experiments to synthesize complex organic compounds, such as pharmaceutical intermediates or natural products.

    Throughout the project, you’ll show your teacher what you’re learning through smaller assignments. At the end, you’ll complete a final project or test to show everything you’ve learned. You and your classmates can also create quick presentations to showcase the knowledge you have gained as well small quizzes to test each other’s understanding of the topic.

    Step 8: SHARE YOUR WORK

    Once your project is finished, you’ll share it with your classmates, your school, or even your community. This could be a presentation, a demonstration, or a showcase of your work.

    Step 9: REFLECT ON YOUR LEARNING

    After the project, you’ll think about what you learned, what you liked, what was hard, and how you can use your new knowledge in the future.

    Step 10: REVIEW THE PROJECT

    Finally, you’ll think about the project as a whole. What worked well? What didn’t? How can you do better on the next project? This will help you do even better on your next PBL project.
