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

Did you complete a science fair project in school? Do you remember measuring the variables, making graphs, and presenting your poster board?

The students in my physics classes live in a poor inner city area.

80% of the student body qualifies for free or reduced lunch. Even with their disadvantages our graduation rate is over 90%, because we inspire the students to be the best of what they can be.

My Project

My students need one turbidity sensor for analyzing how many particles are in water and one light sensor for analyzing the intensity of light given off by a substance. My students kindly requested these materials for use with their science fair projects. Several students are looking at how the purity of water affects different plants, and the purity of drinking water obtained from different sources. Several students are trying to create the better Mountain Dew glow light, and learn the luminosity given off by different chemical reactions.

It is so important to inspire our students into the fields of math and science and the science fair is one of the tools I use to motivate them.

These probes make the students feel they are doing real scientific work, worthy of consideration when they use the most advanced tools.
