I teach chemistry with the belief that students understand the subject when they can connect what they
see in the laboratory to what is happening at the particle level and then use those ideas to explain or
predict what will happen next. Chemistry can easily become a course of formulas, vocabulary, and
procedures, but I want students to see the logic underneath them. My role is to provide accurate content
and careful structure while giving students regular opportunities to reason from evidence.
I begin units with observable phenomena or questions that can lead students toward a chemical
explanation. A change in temperature, a reaction that produces a gas, differences in solubility, a
corrosion problem, or a question about energy can give students something concrete to investigate. I
ask students to describe what they notice, make a prediction, and identify what evidence would help
distinguish among possible explanations. As the unit develops, we connect the macroscopic observation
to particles, interactions, and chemical representations.
Models are central to my chemistry teaching because many of the most important processes cannot be
observed directly. Students use particle diagrams, molecular models, energy diagrams, graphs,
equations, and other representations to explain what is happening. I ask them to revise models when
new evidence does not fit the original explanation. Moving among observable phenomena, symbolic
equations, and particle-level reasoning helps students understand why a chemical equation represents
more than a set of symbols to balance.
Laboratory investigation should involve thinking as well as technique. I explicitly teach safety,
measurement, equipment use, and procedures, but I also want students to make decisions about
variables, data collection, controls, and the limitations of a method. Depending on the course, students
may investigate reaction rates, properties of substances, acid-base behavior, energy changes, or
quantitative relationships. We examine unexpected results rather than automatically labeling them
mistakes, and I ask students to consider whether the evidence is sufficient to support the conclusion
they want to make.
I use direct instruction when students need a clear explanation of difficult chemistry. Concepts such as
bonding, stoichiometry, equilibrium, thermochemistry, and molecular structure require carefully
sequenced knowledge and mathematical fluency. I use worked examples, visual representations,
guided practice, and targeted questioning, then shift the responsibility back to students. I want students
to move from seeing a problem that looks familiar to identifying the underlying chemical relationship for
themselves.
Mathematics is part of chemical reasoning, not an unrelated task added to the end of a lesson. Students
need practice with ratios, proportional relationships, unit conversions, graph interpretation, significant
figures, and quantitative representations when those tools are appropriate to the chemistry being
studied. I encourage students to estimate before calculating, track units, check whether an answer is
chemically reasonable, and explain what a numerical result means. In quantitative work, I value
reasoning and interpretation as much as getting the final number.

Assessment should reveal chemical thinking. I use prediction questions, particle sketches, brief
calculations, reaction explanations, exit responses, lab reflections, and whiteboard problems to identify
misconceptions during instruction. Larger assessments may ask students to interpret data, construct or
revise a model, explain a reaction, use mathematical representations, or connect multiple levels of
representation. When I give feedback, I try to identify whether the problem is conceptual,
representational, mathematical, procedural, or related to the interpretation of evidence.
I am intentional about inclusion because students arrive in chemistry with different levels of mathematics
preparation, laboratory experience, language development, and confidence. I provide visual models,
vocabulary support, worked examples, structured laboratory roles, and multiple representations of
difficult ideas. I break complex quantitative problems into reasoning steps without removing the
chemistry from the task. I also create opportunities for students to explain their thinking in different
ways, because a student's first language or comfort with formal scientific writing should not be the only
measure of their understanding.
Safety, responsibility, and scientific integrity are part of my classroom culture. Students learn why
goggles, appropriate handling, accurate labeling, cleanup, and careful measurement matter. They also
learn that changing a data point to make a result look better is not acceptable scientific practice. I expect
students to report observations honestly, distinguish observations from conclusions, discuss uncertainty,
and acknowledge limitations in a method. These habits matter whether students continue into laboratory
science or simply use scientific information in everyday life.
Ultimately, I want students to leave chemistry able to move confidently among evidence, models,
mathematics, and chemical representations. They should be able to observe a phenomenon, ask a
useful question, propose an explanation, test it, analyze the evidence, revise a model, and communicate
what the evidence supports. Whether they continue into medicine, engineering, environmental science,
technical work, college study, or another field, I want them to retain the habit of looking beneath an
observable change and asking what mechanism could explain it. I also keep improving my teaching by
studying student work, reflecting on laboratory investigations, and adjusting explanations and problems
when students reveal a more productive route into the chemistry.
