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,...

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...

Thirty multiple-choice questions and their answers are provided in this resource. It was written for a general chemistry course and queries test takers on scientific notation, mixtures, chemical symbols, electric charges, Dalton's atomic...

Young scholars study the significance of the quantum model and how scientific theories adapt over time.  In this investigative lesson students describe the contributions that scientists have helped develop the atomic theory and...

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,...

Young scholars investigate relative mass using 8 different items. In this relative masses lesson plan, students discuss as a class John Dalton's atomic theory. They take the masses of the 8 items and record their data. They discuss...

In this atom worksheet, learners define the atomic theory, compare an atom and a molecule, determine atomic number and number of protons for elements, and draw Bohr models for given elements. This worksheet has 4 graphic organizer, 8...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

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.

Students explore nuclear scientists.  In this nuclear science research lesson, students choose a scientist who has contributed to nuclear theory, research his/her life and accomplishments, and write a paper. Students generate...

Studdnts research ancient texts and compare ancient Greek atomic theories, as used in the production of silver, to modern theories.

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

This wonderful recap of powerful figures in scientific history includes pictures, important dates, and the information about their inventions or impact. Atomic structure and the photoelectric effect are introduced. The first slide gives...

Learners 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.

Accommodate your chemistry class with an experiment that is both entertaining and educational. Through the activity, blossoming chemists perform calculations on various isotopes, as represented by beans and legumes, to obtain...

Words, words, words! This presentation uses plenty of them to define the atom, outline the history of what we know about atoms, and explain atomic and mass numbers. That's all! Informative, but not interesting, this slide show would be...

Atomic theory as a philosophical study was explored even by the Ancient Greeks. The knowledge of atoms was developed in the 17th century.  This PowerPoint explains how by the 1940's, splitting of the atom was discovered and since...

In this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.

Students investigate the scientists that have contributed to the modern day atomic theory. They conduct Internet research, develop a table, record data, and produce a webpage about their selected scientist.

Ninth graders examine how scientist's contribute to atomic theory.  In this development of a scientific idea lesson students work in groups and research the development of the atomic model. 

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...

Pupils 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

Eighth graders explain the development of the atomic model over time. In this chemistry lesson, 8th graders research about the scientists who made a contribution to the atomic theory. They create a three-dimensional model based on their...

Students read passages and view a slide show on the theory of evolution and provide evidence that this theory is correct. In this evolution lesson plan, students read about fossils, anatomy, organs, fetal development, and more.
