Celebrate Black Teachers and Students

This project is part of the Black History Month celebration because it supports a Black teacher or a school where the majority of the students are Black.

My Students

In a typical day in my classroom, 30 students work on basic Biology & Chemistry labs. They are engaged and enthused about learning biological & chemical principles. They work collaboratively and actively participate in class. At the end of the year, I want them to gain proficiency in Biology and Chemistry and see its relevancy.

They speak English, French, Spanish, Wolof, and Igbo among other languages.

They are typical teenage students who are going through typical teenage challenges: peer acceptance, relationships, etc. They also have some challenges that are germane to their environment. There are gang related issues, poverty, and unemployment. This project is particularly aimed at providing them with opportunities to examine macroscopic chemical phenomena.

My Project

The concept of moles and Avogadro's number are fundamental principles in chemistry. My students have a hard time conceptualizing moles because it is such an abstract idea. My students will use these materials to get a tangible sense of moles. They will use the scales to measure the mass of copper, iron, and aluminum. They will identify the atomic masses of these elements on the periodic table and calculate the number of moles of each metal. They will see that a mole of a substance is equivalent to the atomic mass in grams. The topic is typically done without measuring any actual items.
