Chemistry and Biology that understand, connect, and apply each other

My high school Chemistry and Biology classes are designed to help students understand science clearly, dynamically, and meaningfully, integrating key concepts with real-world applications. I guide my students in developing a deep understanding that goes beyond memorization, fostering analysis, scientific reasoning, and critical thinking.

With a solid background in Food Biotechnology and extensive teaching experience, I integrate modern methodologies such as problem-based learning, case studies, digital simulations, and interactive activities that connect chemistry and biology with topics such as health, nutrition, genetics, biotechnology, sustainability, and the environment.

The classes are personalized and adapted to each student's pace, reinforcing content, preparing for assessments, and developing key scientific skills: data interpretation, understanding processes, scientific argumentation, and problem-solving. My approach aims to help students gain confidence, academic independence, and a passion for science.

These classes are ideal for students who:

They want to understand Chemistry and Biology without frustration

They seek to improve their academic performance

They need personalized support

They want a science that is current, applied, and connected to real life.

Science with meaning, learning with purpose, and support that makes a difference.
