Designed to use when teaching adults preparing for their high school equivalency exam, the resource integrates reading practice, writing, and analytical thinking in every lesson. The unit covers 23 topics, but it only includes three...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Class members use the provided worksheet to create a resume for one element from the periodic table. The activity teaches learners about all of the properties of elements and how to read the periodic table.

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

Resource investigates the beliefs of Dalton's atomic theory which consists of four parts. Which points do we still use today, and what have we learned since Dalton?

This guided lesson summarizes the historical development of atomic theory.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will explain the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. They will also...

This tutorial reviews over the basics of atomic structure.

[Free Registration/Login may be required to access all resource tools.] Reintroduction of the idea of the atom and the billiard ball model.

Read and fill in the blanks of this passage explaining atomic history. Each blank has a dropdown menu with choices. When you finish, click CHECK MY ANSWERS. If you pick a wrong answer, the right answer will be displayed along with your...

This lesson focuses on the structure of atoms. All substances are made from atoms. Each atom is made of a nucleus - containing protons and neutrons - surrounded by electrons. It provides a link to an assessment.

Questions related to the electronic structure and atomic chemical behavior of acid and bases.

Learn about the models of the atom that have been proposed throughout history. Presents Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and the modern theory of the atom. Sections are accompanied by journal...

Slideshow looking at the history of models of the atom, including those proposed by John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick. Discusses subatomic particles, including the numbers of protons, neutrons,...

By the end of this section, you will be able to express the ideal gas law in terms of molecular mass and velocity; define thermal energy; calculate the kinetic energy of a gas molecule, given its temperature; describe the relationship...

This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals...

[Free Registration/Login Required] How can we predict an atom's structure, if we cannot see an atom? Using the Rutherford's Gold Foil Experiment, make your own model and test out the model.

Provides good objectives to go along with a text discussion of hybridization. Complete with illustrations, charts, and graphics.

The beginning of an informative tutorial on antimatter, covering quarks, hadrons, baryons, mesons, leptons, and neutrinos.

Investigate why a charged object is attracted or repelled by another charged object. Explore the concept that the attraction between positive protons and negative electrons holds an atom together.

A tutorial that presents models of the atom proposed by John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. Each is supported by an animated illustration. Includes comprehension questions and a quiz at the end.

Learn about atomic structure and the multiple theories of atomic structure in this simulation.
