A student’s interest in STEM often begins in high school, where passionate teachers make complex studies like biology, chemistry, and computer science engaging and accessible. A motivated, enthusiastic teacher can turn daunting subjects into exciting opportunities, showing how science and technology connect to the real world.

STEM teachers are vital in sparking curiosity, imparting essential skills, and preparing the next generation for careers that address real-world problems. The STEM department at Hansberry College Prep (HCP) has some of the most dynamic, innovative, and creative teachers. Our students are always excited to attend and participate in the highly interactive lessons these teachers create.

We applaud and salute each of our STEM teachers’ excellent heart work and hard work. They ensure our Bengals know the value, knowledge, and power of STEM. Here are some highlights from two of our great HCP STEM teachers:  

Tiffany Johnson | 9th Grade Biology

Education: Bachelor of Science in Biology, Illinois State University
Years at HCP: 7 years

Johnson holds a some sort of chemical equipment behind a glass shield. She is dressed in light blue protective gear and wears gloves and glasses. She is a woman with long straight black hair in a high ponytail and brown skin.

What do you love about teaching?

I love all the different personalities and experiences each student has! They also keep me up to date on the latest shoes, hairstyles, and music!

Why is STEM important?

STEM provides opportunities for creative thinking and unique experiences. Most of my life-changing experiences stemmed from my degree and interest in various STEM-related careers.

How do you motivate and support your students?

I motivate my students by making formative assessments (how teachers analyze learning in the moment) competitive, allowing them to “show off” their knowledge during competitions with their peers. To support individuality in the classroom, I give students autonomy throughout the class period, allowing them to choose how they want their science lessons to unfold.

What is a day like in the classroom?

There’s really no way to describe a typical day in my classroom. Every day brings something new, but the good days outnumber the bad. I love hands-on activities, and the students do as well. We do a lot of labs.

Connor Celeste | 10th Grade Chemistry

Education: Bachelor of Science in Integrative Neuroscience, Binghamton University
Years at HCP: Just finished first year

Celeste gives two thumbs up next to two of his students in his classroom. They are all wearing protective equipment for a lab. Celeste is a man with short wavy dark brown hair, a full beard, and light skin. Underneath a gray apron, he is wearing a white, long-sleeved button up with a gray vest and black tie.

What do you love about teaching?

The moment a kid realizes something and recognizes what they are learning.

Why is STEM important?

We live in a world where information can be misleading, whether intentionally or not. Understanding the science, math, engineering, and everything behind how the world works is going to prepare our students better to make informed choices.  

What is a highlight from your first year of teaching?

I led the art club this year. It was great seeing my students in a different light. It was a therapeutic environment to put their thoughts on paper

What do you look forward to next school year? 

Next year, I want to do a lot more labs. Labs with hydrochloric acid and metals. I would like to do a titration lab. I want to teach the kids how to use technology to measure gas and pressure.  

STEM teachers are so much more than instructors; they are the architects of a future that will be defined by the advancements their students create. At Hansberry, our STEM teachers are invaluable, and we see and appreciate the impact they have on our students.
