After showing they quick-paced featurette on the breaking of bonds, hold a discussion using the accompanying Think questions. Complex molecules are broken down into smaller molecules during digestion. There are six main molecules that...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

Part of a longer film, "Our Friend the Atom," this segment focuses on how nuclear radiation was discovered. Ping-Pong balls and mouse-traps combine to show a very visual demonstration of how nuclear reactions occur. The dangers of...

Your fifth graders will totally get atomic structure after viewing this clip. The Bohr Model of the Atom is defined by its parts, mass, and function. Each part of the atom is personified to help learners remember what they are and how...

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Biology learners should understand a few chemistry basics. Here is a worksheet that introduces them to the concepts of chemical reactions, molecular bonding, and the unique combination of properties that make water vital to life....

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

Drawings on an interactive whiteboard are used to introduce the basic structure of an atom. Technically, the model drawn is inaccurate, as three electrons are shown on the innermost orbital. Electron orbitals are not the intent of the...

As the title implies, this PowerPoint defines and illustrates the basic terms involved with describing matter. Phases of matter, atomic structure, and the different categories of compounds are included. Slides are simple and uncluttered....

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

Students explore atomic structure. They observe a video on atomic structure and complete a Venn diagram on the parts of the atom. Students create their own graphic organizer on the parts of the atom using Inspiration software.

If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...

In this electron learning exercise students find values for the given letters including their subshells and in which orbital it occurs. 

In this moles instructional activity students complete a set of calculations to find how many atoms and moles are in different substances. 

In this chemistry worksheet students complete a set of multiple choice and short answer questions on protons, electrons, ionization and chemical equations.

In this chemistry worksheet students complete a series of multiple choice and short answer questions on elements, chemical reactions and balancing equations. 

In this general chemistry worksheet students complete a series of multiple choice and short answer questions on elements, chemical properties and various chemical reactions.

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. 

Students describe the science of physics. For this Physics lesson, students observe examples of physics within their classroom. Students create a definition for physics.

In this science instructional activity, students choose the multiple choice science term that best matches the 15 definitions stated. Students circle their answers.

In this atomic models time line worksheet, students draw a diagram of Democritus, Dalton, Thomson, Rutherford and the Electron Cloud model of the atom.

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 Bohr atom learning exercise, students complete a table with the number of electrons of the element, the electron configuration, the mass number, the number of protons, the number of neutrons, the element, the symbol and the...
