In this atoms worksheet, students circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.

Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

In this Rutherford model worksheet, students read about Rutherford's experiment with gold foil and alpha particles which led to the discovery of subatomic particles. Students answer six analysis questions about the experiment and...

Students build metal atomic models using styrofoam. In this chemistry lesson, students identify the different unique properties of metals. They explain how metal atoms bond.

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.

Eighth graders experiment with a Geiger counter and a dosimeter to test the amount of radiation in a room and the amount of radiation received in a day. In this radiation energy lesson plan, 8th graders test the shielding effect of...

Although there are only 16 questions here, this chemistry handout makes a terrific unit assessment. It queries youngsters on the properties of ionic and covalent compounds, relates bond length tho stability and enrgy, compares polar and...

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...

High schoolers will draw Lewis structures of common covalent compounds using a Chem 3D computer program. They will predict the shapes of the molecules, complete a data table, and formulate rules for predicting shapes of molecules. In the...

Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.
