Explore a chemistry activity designed to have students measure quantities and calculate the moles and number of particles contained in the sample.
A new lesson that uses PES evidence to drive the instruction that would allow the students to identify the limitations of the Bohr model and introduce the Quantum Mechanical Model .
Kristen Drury came up with a fun new project for her class, “Create a Game: Shark Tank Presentation.”
Kristen Drury explains some major shifts in her teaching philosophies and how her flipped classroom has evolved as a result.
After teaching the concepts and calculations for acid and base strength, concentration, percent ionization, and pH I noticed many of my students were struggling to make meaningful connections between these calculations.This lesson was created to strengthen the understanding of the relationships between these concepts and skills.
These are a few reflections from an AP Chemistry Exam reader after reading the 2020 online AP Chemistry Exam.
AACT has organized eight virtual symposia to provide professional development for teachers this summer. These symposia can truly help teachers plan for the next school year and virtually “see” one another to share ideas and concerns.
In this lesson, students are offered a variety of alternative versions of the periodic table. Students will identify trends that are consistent from one table to the next in order to understand why the tables they are working with and Mendeleev's version are organized in the manner that they are. This lesson was designed to fit the NGSS performance expectation HS-PS 1.1 but can be used for any first year chemistry course or modified at your discretion.
