My Students

My students attend a Title 1 school, where 85% of the student population is economically disadvantaged. The campus leads the district, for high schools, in the number of students identified as an English Language Learner (40%) and those that receive Special Education services (13%).

Many of my students either come from a single-parent home or a home where the primary language is a language other than English.

While the parent(s)/guardian(s) of my students may not always have an opportunity to meet me in person, they do make attempts to communicate with me to ensure the success of their child.

My students have dreams and aspirations to attend college or find work after high school. Despite circumstances beyond their control, my students continually demonstrate a commitment to learning through their daily attendance; and by valuing the campus tradition of pride, respect, and responsibility.

My Project

I currently am unable to purchase liquid nitrogen from a supply company because I lack a safe method to retrieve and transport liquid nitrogen. The cost of a dewar would exhaust the limited funds the science department received at the beginning of the school year.

The use of liquid nitrogen will allow me to demonstrate various concepts to chemistry students ranging from gas laws, changes in elasticity, phase changes, kinetics, and connections to biological membranes.

This also will provide students with the opportunity to observe and interact with liquid nitrogen in a controlled setting instead of watching videos about it.

Students will also have the opportunity to participate in science demonstrations for feeder schools to help promote and grow our advanced science courses.
