Welcome to the Lab

Chemistry, physics, teaching strategies, and classroom technology, all in one place.

Choose Your Element

Chemistry, AP Chemistry, and Physics: notes, lab activities, and practice.

Classroom-tested strategies, routines, and tech, from note-taking to brain breaks, ready to try in your own room.

Life outside the classroom: rides, food, projects, and a little science when it sneaks in.

Chemistry · Ionic Bonding

Count valence electrons, pick the shorter path to 8, and predict the charge of any main-group ion. Includes hints and quick self-checks.

Chemistry · Ionic Bonding

Show how metals hand electrons to nonmetals, then turn the drawing into a formula. Comes with a practice worksheet.

AP Chemistry · Unit 3

One equation, four variables. PV = nRT, the classic gas laws, partial pressures, and five fully worked examples.
