Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons,...

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...

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...

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

What's the likelihood of your class understanding probability maps? Young scientists explore the concept using a virtual dartboard in an interesting simulation. The darts establish a pattern around the bull's-eye, which provides a visual...

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

Students explore scientific theories and the works of scientists.  In this chemistry lesson students develop a timeline  that shows how scientists work was built on the ones before them. 

For this atom worksheet, students review the subatomic particles, the scientists associated with the atomic theory, and the periodic table. This worksheet has 15 matching, 24 fill in the blank, and 11 short answer questions.

In this matter and atoms worksheet, high schoolers will fill in the number of protons, electrons, and neutrons for five different atoms. Then students will fill in the blanks of five statements with words from a word bank. Finally, high...

Start this lesson with a bang! The eighth in a 13-part series of lessons explains the origin of elements beginning with the Big Bang Theory. The reading describes the formation of elements hydrogen through uranium.

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

Delve into the world of quantum mechanics by viewing this PowerPoint. Chemistry novices learn about electron energy and shells, and they practice listing electron configuration for different atoms. Because this presentation provides...

Your students should enjoy this slideshow which includes some basic definitions about the atomic structure of atoms. In fact, this presentation would be best-viewed before giving details and diagrams of neutrons, protons and quarks. The...

Chemsitry aces learn that protons are located in the nucleus and the number of protons in the nucleus determines the atomic number of an element. In this lesson, they compare materials made up of a single element and other materials...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

For this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each...

Familiarize your new chemists with the periodic table of elements by contemplating this collection of slides. Element groups are identified, atoms are defined, and nuclide notation is explained. Isotopes are also mentioned. The topics...

In this atomic structure worksheet, high schoolers answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and what...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

This is a basic presentation that can be used to introduce your budding chemists to the structure of an atom. It gives step-by-step examples of a few atoms, showing their particles as well as their chemical formulas and the associated...

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

In molecules, bonds rotate about the nucleus due to the repulsion of subatomic particles. In a simulation, learners manipulate the bonds of a molecule to meet the atoms' needs. They can then see the specific molecular shapes of five...
