Courses

What we're studying

Both courses run on the school's six-day cycle. Each has a full syllabus below; day-to-day plans, objectives, and homework live on the class schedule.

Environmental Science

How Earth's systems fit together and what happens when people change them — energy, climate, water, ecosystems, and the trade-offs behind real decisions. Heavy on data, fieldwork, and argument from evidence.

  • Systems & cycles
  • Energy
  • Data analysis
  • Fieldwork

Anatomy & Physiology

Structure and function from the cell up to whole body systems, with an emphasis on how the parts work together, how we know what we know, and what goes wrong when a system fails.

  • Body systems
  • Structure & function
  • Lab work
  • Case studies

Virtual labs

Simulations

Labs you run in the browser. Change one thing, watch what happens, and explain why. They work on a Chromebook, a phone, or the classroom board.

All 4 labs

Population Limits Lab

Why can't a population grow forever? Grow duckweed on a pond, follow the reindeer of St. Matthew Island, and test trout in water of different pH.

Sea Otters and Kelp Lab

Count urchins and kelp on two Aleutian islands the way Jim Estes did, model a coast with and without otters, and test what holds California's otters back.

Anatomy & Physiology

All 4 labs

The Human Skeleton

All 206 bones in 3D. Turn it, take it apart, sort the bones by shape or region, and quiz yourself on every one.

Open the lab

Skin Under the Microscope

Measure the layers of thin and thick skin with an eyepiece scale, test how deep a cut must go to bleed, follow one skin cell for four weeks, and pull on the dermis.

Chemistry

All 4 labs

Salt From Poison

A metal that burns in water plus a poison gas makes table salt. Run the demo schools no longer allow, watch one electron jump, and build other salts.

Open the lab

Atomic Spectra

Watch atoms take in energy and give it back as light. Light up tubes of hydrogen, neon, mercury and more, then name a mystery gas by its colors.

Open the lab

The Periodic Table in 3D

Every element is a tower. Switch the height between atomic radius, ionization energy, electronegativity and more, and watch the trends across the table.

Open the table

See all 12 labs, with worksheets, slides and teacher guides. Also from class: Tragedy of the Commons and Electron Shells.

How to keep up with class

Check the schedule

The class schedule shows what we did and what's assigned, week by week. It's the fastest way to catch up after an absence — no login required.

Watch for graded work

Grades, missing assignments, and official announcements stay in the district's systems. This site is for course information and resources, not for grades or student records.

Reach out early

If something isn't clicking, the best time to say so is before the test. Email or text me — details are just below.

A note on privacy. This is my own site, not an official City Honors or Buffalo Public Schools page. It never contains student names, grades, photos, or any other student information — only course materials and general classroom information.
