Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

A study of the periodic table of elements doesn't have to be elementary! Deepen understanding of the building blocks of chemistry with an interactive periodic table. At first sight, the table looks like a standard reference page, but a...

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.

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.

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

In this periodic table worksheet, students answers 10 fill in the blank questions by reading information form a periodic table. Then also complete Bohr Models of the atoms of 12 different elements.

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...

Eighth graders investigate objects for a specific element from the Periodic Table.  In this elemental photography lesson, 8th graders observe for and object and photograph it. Students use photographs to prepare a multimedia...

You can't tell by the title, but this is a functional periodic table of elements. Incorporating bright colors, lucid text, and easily operated features, this application serves as a valuable reference tool for your chemistry class.

Here is a six-page exploration that will spark interest in the periodic table of elements. After reading a diagram-supported explanation of the periodic table's organization, pupils answer questions to familiarize themselves with it. To...

Students explain how the elements are arranged in the periodic table. In this chemistry instructional activity, students determine the subatomic particles for certain elements. They research the physical and chemical properties of an...

In this writing nuclear reactions worksheet, students read about nuclear equations for alpha decay, beta decay and positron emission. They are given the rules for writing nuclear reactions and a sample problem.

For this nuclear power worksheet, students read how atoms can be changes and are unstable. Students compare 3 kinds of radiation and the difference between fission and fusion. Then students complete 10 matching and 2 short answer questions.

Students sort a group of manipulatives and then explain their organizational system to the class. They discuss the work of scientists trying to organize the elements into a system that made sense and the development of the periodic table.

In this atom worksheet, high schoolers answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

In this minerals and rocks activity, students answer questions about the chemistry of minerals, scratch tests, rocks and the rock cycle, and erosion and deposition.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

Students research elements on interactive Internet periodic tables, take notes using Inspiration software, and write descriptive paragraphs with graphics. They create presentations.

In this atoms activity, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be asked to define atomic number, mass number and understand how isotopes differ from one another. They will be able...
