Biology Classroom Tools

Interactive activities I build for my ninth-grade Biology I and Advanced Biology I classes, filed by unit so any Virginia teacher can find the one that fits tomorrow’s lesson. Each runs in Safari on a school iPad with no login and no printing, and each is mapped to the Virginia Biology SOL and to the Prince William County Public Schools pacing guide. Units and block counts follow the PWCS Biology I pacing guide for 2026–27. Each tool keeps its Bio Tool number for good; numbers run in the order the tools were built, and a tool that serves two units appears in both.

All year Science and Engineering Practices

Embedded in every PWCS unit

Virginia SOL for this unit
  • BIO.1a–f scientific and engineering practices, embedded in every unit rather than taught on their own

Unit 2 Cell Structure & Function

PWCS pacing guide · Quarter 1 · 8 blocks

Virginia SOL for this unit
  • BIO.3a cell theory is supported by evidence
  • BIO.3b structures in unicellular and multicellular organisms work interdependently to carry out life processes

Unit 5 Cell Growth, Division & Specialization

PWCS pacing guide · Quarter 2 · 10 blocks

Virginia SOL for this unit
  • BIO.3c cell structures and processes are involved in cell growth and division (mitosis)
  • BIO.3e specialization leads to the development of different types of cells
  • BIO.5d meiosis has a role in genetic variation between generations

Nothing here yet. New tools are added as each unit is taught.

Unit 6 Genetics & Heredity

PWCS pacing guide · Quarters 2–3 · 8 blocks

Virginia SOL for this unit

Nothing here yet. New tools are added as each unit is taught.

Unit 7 Evolution

PWCS pacing guide · Quarter 3 · 8 blocks

Virginia SOL for this unit
  • BIO.7a evidence is found in fossil records and through DNA analysis
  • BIO.7b genetic variation, reproductive strategies, and environmental pressures affect the survival of populations

Unit 9 Bacteria & Viruses

PWCS pacing guide · Quarters 3–4 · 5 blocks

Virginia SOL for this unit
  • BIO.4a viruses depend on a host for metabolic processes

Nothing here yet. New tools are added as each unit is taught.

Unit 10 Ecology

PWCS pacing guide · Quarter 4 · 8 blocks

Virginia SOL for this unit
  • BIO.8a populations interact through carrying capacity, limiting factors, and growth curves
  • BIO.8b nutrients cycle with energy flow through ecosystems
  • BIO.8c ecosystems have succession patterns

Nothing here yet. New tools are added as each unit is taught.

Using these with Canvas

The tools send nothing back to the teacher, so collect the work with a screenshot uploaded to a Canvas assignment. The steps, what to do about answer keys, and what to do when students share iPads are in A Note to Teachers Using the Classroom Tools, which is updated as new tools arrive.
