My Students

My students are growing in their interest and ability to innovate. Although they may be at different stages of innovative thought, my students share at least two traits. My students are amazing people! They are eager to design and build their own unique experiences, and they are interested in learning and applying new tools.

Our charter school has a mixed population of 64% Title I (unduplicated count) students from predominantly urban settings.

Students of all races and a number of ethnic backgrounds work together in a safe and secure environment. Our school demographics are as follows: 3.8% Asian, 31.2% Afro-American, 30.1% Hispanic 5.9% multiracial, and 29.0% White. Students at our school are motivated and enthusiastic when given the opportunity to show their inventiveness and talents.

My Project

It still amazes me how excited students get about experiments that they have designed. These supplies will my students develop novel experimental designs to discover how algal ball conducts photosynthesis and cellular respiration. The students will explore the various inputs and the impact of changing the variable amount forces the rate of photosynthesis to change.

Students craft their own experimental designs.

These designs allow them to get a deeper understanding of the process of photosynthesis and cellular respiration. They will start by trapping algae within a "ball" that they created chemically. This allows is awesome. They then will develop an experimental design based on the variable that they think will impact the rate of photosynthesis the most.
