History of Atomic Theory
Using the Bohr model, review the structure of an atom with your young chemists. Groups will then work together to research a scientist who contributed to our current atomic theory: John Dalton, J.J. Thompson, Ernest Rutehrford, or Niels Bohr. They record the information on a chart and then present it to the class. A grading rubric is included for your convenience.
The Atom, Atomic Number, Mass Number, and Isotopes
Expose your chemistry learners to atomic theory. As they view this PowerPoint, they will learn about subatomic particles, atomic number, and mass number of atoms as well as how isotopes are structured. Throughout this neat and accurate presentation you will find learning-check slides that can be used to assess understanding.
History of Atomic Theory
Students study the significance of the quantum model and how scientific theories adapt over time. In this investigative instructional activity students describe the contributions that scientists have helped develop the atomic theory and identify the locations of the atomic structure.
History of the Atomic Theory
Students work together in groups to research a topic related to the atomic bomb. They create a worksheet summarizing the information they gathered and write a letter to John Dalton discussing the advancements in atomic theory.
New! Atomic Theories Chart Worksheet
Here is a research assignment for your physical scientists on the history of atomic theory. Pupils look up information by the name of contributing scientists. Designed as a large data table, the page requires learners to write a description of the theory or experiment that was done to develop it, sketch a model representing the theory, and provide a works-cited reference using APA format. This clever assignment familiarizes learners with the work of Dalton, Rutherford, Bohr, and others.
New! Just How Small Is an Atom?
Using a massive cartoon blueberry as an atom model, an animated astronaut describes an atom's anatomy and the density of its nucleus. After showing this featurette, you can have young physical scientists construct atom models. Also, be sure to set learners up at computers to explore the interactive resources available through the Dig Deeper feature.
What Is Inside the Atom?
Four lessons make up this mini unit about atomic structure and spectra. A pretest is provided to give an idea of what is already known about the atom. Through a series of demonstrations and lecture, you present the information to young chemists. They construct a fruit model of the boron atom. They fill in a chart using the periodic table of elements. They compare and contrast two potatoes as an example of how isotopes are related. Asides from the dissection of a fried fish head, this is a terrific set of lessons for introducing the atom and radioactivty.
Defining the Atom
On "Defining the Atom," physical science starters fill in blanks, determine if statements are true or false, match terms with the appropriate definitions, and solve problems. Questions are about Dalton's atomic theory, the atom and its general composition. This is a compact and applicable homework assignement for any general chemistry class.
Atoms, Molecules and Ions
Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes by teaching how to name molecular compounds, including acids and bases. An added plus to this slide show is the practice problems that are inserted throughout.
History of the Atom
This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse the periodic table of elements and discover electromagnetic forces. This is a classy and comprehensive compilation of chemistry slides that even includes a link to a 13-minute video.
Review Models of the Atom
Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history and electron interaction. An excellent topic for classes with an introduction to atomic theory. It is also a suitable jumping-off point for further research.
Atomic Structure and Quantum Theory
Learners are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory
Discovering the Structure of the Atom
Students apply the processes of scientific inquiry to investigate atomic and nuclear structures of matter. They examine historical atomic theories and they use data from the scattering experiment to analyze and determine if the experiment supports or refutes the prevailing theory.
Activity #3 Are Particles "Real?"
Students verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic theory, is the idea of atoms and moleucles existing as submicroscopic particles, can be used to explain what happens in chemical reactions and to comprehend the basis for the law of conservation of matter.
Ancient Atomic Theories
Studdnts research ancient texts and compare ancient Greek atomic theories, as used in the production of silver, to modern theories.
Atomic Theory, Structure, and Symbols
In this atomic theory worksheet, students review the observations that led to the conclusion of the atom having a positively charged nucleus. Students compare atomic number and mass number and explain how the discovery of subatomic particles and isotopes affected Dalton's atomic theory. This worksheet has 9 problems to solve.
Atomic Structure - Part A
Students describe the structure of atoms, including the particles that make them up. They recognize that key scientists and experiments have contributed to the changes in the Atomic Theory.
An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks, photons, electron shells and orbitals, isotopes, and more! The graphics are attractive, and the information is educational. Think of this as a library of images and information that you can use to create your own chemistry or physics slide show.
Educational apps reviews are available to members
Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use.
Historical Development of a Scientific Idea
Ninth graders begin with a pre-assessment designed to determine the students' knowledge of atomic structure and how that knowledge has evolved over time. They then work in small groups to investigate a particular scientist's contribution to atomic theory.
