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.
Pupils 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, alkaline...
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
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.
Curated OER
Atomic Structure and Quantum Theory
Students are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory
