What Happens When We Excite Atoms and Molecules?
Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.

Atomic Structure
In this atom worksheet, students define the atomic theory, compare an atom and a molecule, determine atomic number and number of protons for elements, and draw Bohr models for given elements. This worksheet has 4 graphic organizer, 8...

What a Bohr!
Students define, identify and illustrate the parts of an atom, and investigate the Bohr atomic model. Students watch a multimedia presentation to understand an atom's parts and their functions. In groups, they create a model of an atom...

The Day the Atom Died (Grade K-1)
Students investigate what is wrong with the Rutherford atomic model. In this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic model...

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.

Isotopes and Ions
Students examine the concepts of isotopes and atoms. In this powerpoint lesson, students see the balance in numbers of protons, neutrons, and electrons create isotopes and ions of certain atoms.

The Chemical Context of Life
In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific 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...
