Curated OER
Physicists or Philosophers?
Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...
Curated OER
Matter
Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.
Curated OER
Electron Structure of the Atom
In this atoms worksheet, students determine the energy difference between levels and draw diagrams of the different types of orbitals. Students determine the ground state electron configuration for given elements. This worksheet has 14...
Curated OER
Periodic Table Basics
In this periodic table worksheet, students answers 10 fill in the blank questions by reading information form a periodic table. Then also complete Bohr Models of the atoms of 12 different elements.
Curated OER
Modern Physics, Old QT
In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.
Curated OER
Periodic Table Basics 2
In this periodic table worksheet, students create cards for a annotated periodic table then use it to answer 16 short answer and fill in the blank questions.
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
Oh - The Bonds of Matter!
Eighth graders identify the types of bonds elements form. In this chemistry instructional activity, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Supernova Chemistry
By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...
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,...
