Classroom Resources: Atomic Structure
26 – 33 of 33 Classroom Resources
History, Model of the Atom, Atomic Theory, Subatomic Particles, Radioactive Isotopes | High School, Middle School
Rutherford's initial research was studying alpha particles, which he hypothesized were helium nuclei. With the help of Hans Geiger, Rutherford conducted the gold foil experiment, which justifies that the nucleus of an atom is a dense collection of protons and contains the majority of an atom’s mass. It also inferred that most of the atom is empty space and electrons are not located in the nucleus. He won the Nobel Prize in chemistry in 1908 for his studies on radioactive substances.
History, Periodic Table, Model of the Atom, Atomic Theory, Atomic Mass, Subatomic Particles | High School, Middle School, Elementary School
This video tells the story of how Dimitri Mendeleev organized the periodic table, even leaving gaps to be filled in with elements that weren't yet discovered.
Atomic Mass, Subatomic Particles | High School, Middle School, Elementary School
In this video, Sam Kean tells the story of the development of the periodic table. He also pays tribute to each of the major scientific contributors, including Dimitri Mendeleev, who made great discoveries through their efforts to best organize the elements.
Introduction, Elements, History, Periodic Table, Atoms, Subatomic Particles, Electrons | High School, Elementary School, Middle School
In this activity, students will use their creativity to spell their name (first or middle name and their last name) using chemical symbols of elements on the periodic table. For example, you can spell Yvonne using the symbols for yttrium (Y), vanadium (V), oxygen (O), nitrogen (N), and neon (Ne).
Electricity, Electrostatic Forces, Subatomic Particles, Electrons, Electrons | High School
In this lab, students will better understand that opposite charges attract each other, and like charges repel.
Electricity, Energy & Thermodynamics, Subatomic Particles, Law of Conservation of Energy, Cathode, Anode, Electron Transfer, Electrons, Electrons | Middle School
In this lesson students will explore the chemical reaction that occurs within a lead-acid car battery and the role of the battery within a car prior to creating their own batteries.
Model of the Atom, Atomic Theory, Subatomic Particles | Middle School, High School
In this simulation, students manipulate the number of protons, neutrons, and electrons in an element and determine how these effect the mass number, atomic number, and other properties of an atom.
Elements, History, Atoms, Isotopes, Atomic Theory, Subatomic Particles | High School, Middle School
In this activity, students choose from a number of activity options in order to best display their understanding of atomic structure. The RAFT model will be followed for this assignment, which means the students choose their assignment and may modify the assignment based on Role, Audience, Format, and Topic.
