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,...

In this elementary particle mass worksheet, students calculate the mass of elementary particles in kilograms and million electron Volts. Students solve 4 problems finding Top Quark mass, total quark mass of a proton and Strange Quark mass.

Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.

In this science crossword puzzle worksheet, students determine the answers to 7 clues using vocabulary associated with atoms and matter. They fill in the puzzle both across and down.

Young scholars simulate how charged particles move in a particle detector. In this physics lesson, students observe how iron filings behave when magnetic marbles are passed underneath them. They record and draw their observations.

In this etymology worksheet, students read about the history of naming words and how words are named. They think critically by answering three questions about the meaning of words, etymologies and the derivation of words.

An introduction to the six different types of quarks: the up, down, charm, strange, top, and bottom quarks.

Enter your height using inches or meters, and see how tall you are in units, from as tall as the Statue of Liberty and an elephant, down to atoms and quarks. Next, see if you can put the Quarkster characters and yourself in order by height.

Quarks, described here, are particles of matter that cannot be further broken down. Thus they are called fundamental particles. "Explain It In 60 Seconds" is an article series that aims to summarize in a few paragraphs the meaning of...

A thorough review of subatomic particles and the people that discovered them. Each particle has its own link for additional information.
