Christie's breadth across subjects — she holds certifications in both ESL and history and teaches at the college level — makes her a reliable substitute for science classes that need someone who can actually engage students with the material rather than just press play on a video. She's comfortable managing a classroom and keeping lessons on track when the regular instructor is out.

When a science class needs coverage, Cathy's PhD in Materials Science and triple engineering background mean she can pick up virtually any middle or high school science topic — chemical reactions, forces and motion, cell biology — without missing a beat. She keeps lessons moving forward rather than defaulting to busywork.

Between conducting sea turtle comparative pathology research with international collaborators and studying biology at Vanderbilt, Madison has a deep bench of real-world science to draw from. She explains concepts in ecology, cell biology, and environmental science by tying them back to actual research scenarios rather than just textbook definitions. That approach tends to make the material stick.

As a pre-med public health major at UT Austin, Chantelle can step into a science classroom and pick up wherever the regular teacher left off — whether that's labeling cell organelles, walking through the scientific method, or explaining ecosystem dynamics. She keeps lessons interactive and checks for understanding rather than just reading from the textbook.

Philip teaches biology and chemistry at the College Prep, Honors, and AP levels in his day job, so stepping into a science classroom as a substitute means actual instruction continues rather than stalling. He can pick up mid-unit on topics from cellular respiration to stoichiometry and keep students moving forward with the material.

A biology and computer science double major at Northeastern, Eunice can step into virtually any middle or high school science class and pick up where the regular teacher left off. She's comfortable covering everything from cell biology and genetics to physics problem sets, and she explains concepts by connecting them to real-world examples students can visualize.

A biology major now in medical school, Kaitlyn can step into virtually any K-12 science classroom — life science, physical science, earth science — and pick up right where the regular instructor left off. She connects textbook concepts to real-world examples that make even a single substitute session feel productive.

Hi I'm Alliyah! I'm a recent Harvard Graduate ('26) with a Bachelors in computer science and neuroscience and a Spanish Language Citation. I have over 10 years of experience tutoring and have also worked at top tech and research companies (IBM, SpaceX, Kempner Institute, etc.). I'm really passionate about making learning fun! I hope that sessions with me will make the material not just understandable but also enjoyable and applicable. I like incorporating technology, hands-on activities, and real-world applications into my STEM-based tutoring subjects. As a tutor, I specialize in Algebra (Algebra 1 and 2), Calculus (1, 2, and 3), Computer Science (Python, Java, Web Development), PSAT, and neuroscience/neurobiology.

Covering science means jumping between topics like cell biology one day and chemical reactions the next — Spencer's broad coursework in physical science, earth science, biology, and chemistry means he can step in without missing a beat. He breaks down unfamiliar concepts using real-world analogies, making it easier for students to stay on track even when their regular teacher is out.

Stepping into a science lesson mid-unit can be tricky, but Brianna's experience teaching elementary and middle school science topics like the water cycle, ecosystems, and basic physical science means she can maintain momentum without losing students. She leans on hands-on examples and visual models to keep concepts concrete even in a single session.

A fourth-year medical student with deep roots in biology, chemistry, and anatomy, Kavya can step into virtually any science topic on short notice — from cell division in a middle school life science class to acid-base equilibria in high school chemistry. She picks up quickly on where a student left off and keeps momentum going rather than just reviewing old material.

Jennifer's day job is teaching general chemistry at the college level, and she collaborates with researchers across biology, pharmacy, and medicine — so covering a high school science class is well within her range. She can pick up a lesson on stoichiometry, cell biology, or experimental design and run with it, keeping students engaged and on track.

Yinin is currently in a rigorous pharmacy program with deep coursework in chemistry and biology, so stepping into a science classroom as a substitute comes naturally. She can confidently cover lab procedures, review key concepts in chemistry or life sciences, and keep students engaged with the day's lesson plan.

An aerospace engineering student with a genuine love of astronomy — he owns four telescopes — Nicholas brings real scientific curiosity into substitute science sessions. Whether the lesson covers Newton's laws, chemical reactions, or Earth systems, he connects textbook concepts to tangible examples from rocketry, space exploration, and everyday physics. That combination of deep STEM knowledge and enthusiasm keeps students engaged even when the regular teacher is out.

Biology, chemistry, earth science, physical chemistry — Joshua's science range runs deep enough that he can pick up virtually any middle or high school science lesson mid-stream. His bachelor's in biology gives him the content knowledge to answer the unexpected questions that come up when a substitute is running the room. He keeps students engaged by tying abstract concepts back to real-world examples.

Between AP Physics 1 and 2, college-level coursework, and hands-on mechanical engineering labs at RIT, Martin covers the full spectrum of science topics students encounter from middle school through high school. He's especially strong at walking through force diagrams, energy conservation problems, and the kind of quantitative reasoning that ties science concepts together.

Stepping into a science classroom mid-lesson requires someone who can read the room and keep students engaged without missing a beat. Nathaniel's experience with earth science and his background as a researcher give him the adaptability to cover material clearly, manage a classroom, and maintain the momentum a regular teacher has already built.

Covering a science classroom means being ready for anything from cell organelles to chemical equations to force diagrams — and Qays teaches all of those subjects regularly. His background spans biology, chemistry, and physics, so he can pick up wherever a lesson plan left off and actually explain the material rather than just supervising worksheets.
