Curated OER
If My Configurations are Correct
Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Electrical Conduction in Semiconductors
In this electronics worksheet, students explore the properties of semiconductors to complete 17 short answer and problem solving questions.
Curated OER
Physical and Chemical Changes
Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.
Curated OER
Using several learning modalities to teach about the Periodic Table.
Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...
Curated OER
Static Cling
Students work together to discover the concept of static electricity. They participate in an experiment in which they test different objects charge. They make observations and record them for later use.
Curated OER
Quantum Physics
Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...
