Historical Models of Atoms
What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...
Curated OER
Timeline of Atomic Models
In this atomic models time line worksheet, students draw a diagram of Democritus, Dalton, Thomson, Rutherford and the Electron Cloud model of the atom.
Curated OER
Molecular Models Laboratory
Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...
Curated OER
What is a Cloud
Third graders study clouds and how they are formed. They write acrostic poems about clouds and analyze and graph temperature data collected during varying degrees of cloud cover.
Curated OER
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.
Curated OER
Atom and Eve
Students research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.
Curated OER
Matter & Subatomic Particles
Seventh graders divide into small groups to construct several models. Each group builds with an accompanying chart showing the colors of gumdrops used for the protons, electrons, and neutrons.)
Curated OER
Forces And Energy
Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The instructional activity includes background...
