For 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...

In this atomic theory worksheet, students write a skit given a story line using Aristotle, Democritus and Dalton. They are given internet sites to find information about the facts and ideas of these past contributors to science.

In this history of the atom worksheet, students answer questions about Thomson's cathode ray apparatus, Rutherford's gold foil experiment and Dalton's beliefs about the atom. Students identify the number of protons, neutrons and...

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,...

In this Dalton worksheet, students read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

Name is Bond, covalent bond. Through readings and answering questions, classes explore the different types of chemical bonds, their characteristics, valence shell electron pair repulsion theory, and atomic orbitals. 

In this atomic structure activity, students use textbooks and dictionaries to find the definitions of 22 terms associated with atomic structure.

Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for...

In this atomic theory worksheet, students use Planck's constant, Rydberg constant, and Avogadro's number to complete 20 multiple choice questions.

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

For this bonding worksheet, students fill in 8 blanks with the appropriate terms about theories of bonding, they determine if 6 statements are true or false, they match 5 terms with their meanings and they solve 1 problem related to...

In this atoms worksheet, high schoolers complete a graphic organizer comparing the properties of the 3 subatomic particles. Then students complete 1 short answer question.

In this physics worksheet, students review vocabulary terms and key equations associated with the quantum mechanical model. Students apply the quantum theory to explain the photoelectric effect. This worksheet has 5 true or false, 12...

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

In this gamma-ray worksheet, students read about the Fermi Gamma-ray Observatory and how it measures the invisible lumps in space. Students solve 3 problems using an equation to determine the time that gamma-rays travel in space and the...

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

In this atom worksheet, students read about Dalton's contributions to the structure of the atom. They answer five questions about Dalton's ideas, the law of multiple proportions and the law of definite proportions.

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...
