Pupils explain concepts related to static electricity, based on a single example: lightning.

In this isotopes worksheet, students review mass number, molecular notation, electron attraction, and electron orbits. This worksheet has 5 matching and 5 short answer questions.

Students explore DNA structure using materials such as Twizzlers, small colored gumdrops and/or toothpicks.

Students explore genetics, chromosomes and DNA.  In this genetics lesson students design a chromosome and identify a family tree through genetics. 

Imagine having a microscopic camera so small that you could travel inside a cell. This interactive site allows you to do just that. Click on any one of eight individual parts of the cell--cell membrane, nucleus, DNA, RNA, ribosome,...

The parts of an animal cell are presented with descriptions of each of its organelles.

Describes plant cells and the structure and function of their different parts.

The parts of a cell nucleus are described along with a list of the functions of a cell nucleus.

A detailed description of comets, their distinct parts, and the known comets in our solar system. Links are also provided for additional information on related subjects.

Take this 13 question quiz to test your knowledge of the parts of a plant cell. Know vocabulary such as nucleus, chloroplast, and ribosome.

See examples of scales based on a range from ten to the twelfth meters to ten to the negative twelth meters. Examples range from parts of our solar system to the nucleus of an atom.

Take a look at the parts of an atom and learn about its properties.

Presents labeled illustrations of a plant cell and an animal cell which demonstrate the parts that are common and different. Next is a table listing cell organelles and stating whether each is present or absent in a plant or animal cell....

This site lets students practice vocabulary words related to cell organelles. The same vocabulary words are presented in one of four different games for students.

Description of organelles. Links will take you to a glossary with pictures for many of the definitions. Ends with a quiz linked to answers.

Acting as part of an overview on quantum theory, this section of the site deals with questions related to electrons, such as "If the electron cannot be localized, can it be moving?" and "Why does the electron not fall into the nucleus?"

This site features a clear picture of the plant cell with a concise explanation of its key parts and their functions.

Take this interactive, multiple-choice quiz over subatomic particles, then review your score and any missed questions at the end.

Acting as part of an overview on quantum theory, this section of the site deals with electrons and orbitals. In addition to explain what an orbital is, the site explains the movement of the electron in relation to the nucleus.

This site illustrates different parts of a plant and animal cell. The student may then drag and drop labels to the correct cell part.

Describes the different parts of a plant cell.

Explains cell structure and function and describes the parts of a cell.

Discover the organelles of a cell, and how their structure contributes to the cell's function.

This interactive resource provides a large clickable-map graphic of a plant cell. Simply click on the cell part and you are provided with a thorough explanation of nucleus or organelle.
