- The human atom
- Students will act out the role of atoms by dressing up as the atoms of designated elements. They will wear costumes with balloons representing valence electrons. The “atoms” will gain or lose valence electrons in order to achieve chemical stability. The students must then identify the charges of the ions formed.
- Format: lesson plan (grade 8 English Language Development and Science)
- By Kamie Wine.
- Confirming and visualizing Lewis dot structures
- With this activity, students can calculate and visualize the atomic and molecular structures of bonds and lone pairs in the molecule methanol (methyl alcohol, CH3OH).
- Format: lesson plan (grade 9–12 Science)
- By Bob Gotwals.
- History of atomic theory
- This lesson is developed for a regular low level physical science class. In small groups, students will use media and written script to learn and teach each other about major contributions to the development of the atomic theory.
- Format: lesson plan (grade 9–12 English Language Development and Science)
- By Anya Childs and Rhonda Garrett.
- Periodic table
- This lesson provides knowledge about periodic law, groups and periods. Students will be able to identify and label each group with their names. Students will be able to relate atomic number and atomic masses of different elements of periodic table. Students will also be able to discuss periodicity of different properties of elements.
- Format: lesson plan (grade 8–12 English Language Development and Science)
- By Abha Bhatnagar and Meera Madan.
- Atomic spectra and the Bohr model
- Students view continuous spectra from incandescent and fluorescent lights and line spectra of selected elements. Students relate energy to frequency of light seen in the spectra. The presence of only certain lines in atomic spectra is related to Bohr's model of the atom. In a second experiment, students determine electron energies in the hydrogen atom.
- Format: lesson plan (grade 9–12 Science)
- By Lisa Bacon.
- Discovering elements online
- Students will work independently and in small groups to research assigned elements on the internet with sites given in advance. They will then contribute to a class database with their individual information. The database will then be made available for students to again work independently and in pairs to answer questions created from a class discussion to discover relationships about the elements.
- Format: lesson plan (grade 8 Science)
- By Trish Loudermilt.
Resources on the web
- The Exploration of the Earth's Magnetosphere
- Articles and information accompanied by realia-type images, a glossary, a timeline, and a teacher's guide that lead the student on a learning journey about the gases which fill most of space and are ruled by magnetic and electric forces rather than by gravity. (Learn more)
- Format: website/activity

- Dryer sheets
- In this Science Update, from Science NetLinks, students hear how the old saying “opposites attract” relates to your laundry. Positively charged particles are attracted to negatively charged particles, which can cause static cling in clothing. (Learn more)

- Chemicool Periodic Table
- An interactive periodic table with all kinds of information about the elements. Also find chemistry calculators and property graphs. (Learn more)
