Discussion in detail of the structure and function of the nucleus and ribosomes of a cell and how they work together in the production of proteins.

This online slide show presents the basic ideas behind the structure of the atomic nucleus.

[Free Registration/Login may be required to access all resource tools.] Covers the structure and function of the nucleus. Students will learn about the structures associated with the nucleus like the nuclear envelop, the nucleolus,...

This site provides an illustrated and animated story that seeks to answer several questions. What are atoms made of? What is keeping a nucleus intact? What happens if you try to separate two quarks? Are quarks fundamental?

Observe the probable location of electrons around an atom. Trace the electrons over time to draw conclusions about where electrons are likely to be found around an atom's nucleus. How does the trace pattern relate to the electron cloud...

Site highlights the various features of an animal cell. Presents users with a colorful diagram depicting the anatomy of the animal cell. Provides links to obtain more detailed information about the various components found in animal cells.

A nice site which provides descriptions of each of the bones that make up our skeletal system. Then there is a lab activity for students to complete in which they build a skeletal system and describe the structure/function of each bone...

[Free Registration/Login may be required to access all resource tools.] The mRNA, which is transcribed from the DNA in the nucleus, carries the directions for the protein-making process. mRNA tells the ribosome how to create a specific...

This lesson will discuss the structure and function of the nucleus. It is 3 of 5 in the series titled "Nucleus."

This lesson will discuss the structure and function of the nucleus. It is 2 of 5 in the series titled "Nucleus."

[Free Registration/Login may be required to access all resource tools.] The nucleus is only found in eukaryotic cells. It contains most of the genetic material of the cell. It is surrounded by a double membrane, or nuclear envelope, that...

Learn the basic structure and function of the nucleus, or the control center of a eukaryotic cell.

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

Self-guided learning activity where students learn about cell structure and function, different types of tissues, and various kinds of membranes in the body. There is a short quiz at the end of the lesson to check for understanding.

Find out if you know enough about atoms to build them. The goal of the activity is to build an atom of a particular element by dragging the correct numbers of neutrons, protons and electrons into the atom.

This multi-day lesson plan helps students to understand how the models of the atom have changed and how quantum mechanics affects the electrons as they orbit the nucleus.

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

Site provides extensive information in the study of comets. Includes excellent graphics that depict what comets look like as they travel through the solar system. Also includes information on how comets may have effected the Earth's...

[Free Registration/Login may be required to access all resource tools.] DNA contains the instructions to create proteins, but it does not make proteins itself. DNA is located in the nucleus, which it never leaves, while proteins are made...

Dutch version of the well-known "Particle Adventure" physics website that teaches students about atoms, mass, particle physics, and quantum physics. The site discusses theories related to physics and provides other links related to the...

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