Kid's learn about the science of chemical elements. Basic forms of matter made from a single type of atom.

Atoms are very, very small. Atoms are so small that it is often said that there are as many atoms in a single grain of sand as there are grains of sand on all of the world's beaches - certainly a difficult thing to prove, but you get the...

Fun and interesting information about elements. Learn about the periodic table, how they are distinguished, and the different families of elements.

The number of protons in the atom of an element determines its place in the Periodic Table. The number of electrons in an atom is the same as the number of protons. These electrons are arranged in shells or 'energy levels' around the...

This lesson focuses on early ideas about the structure of an atom including John Dalton's plum pudding model and Ernest Rutherford's nuclear model. A link to a test is provided.

Students will find an explanation of the neutron particle located inside the atom's nucleus. Website also defines isotopes and the process of radioactive decay.

The interactive activity examines the Periodic Table of Elements. Learners answer questions about the number of protons, electrons, neutrons, or nucleons that an atom of an element contains.

A very detailed look at the element Gallium, a member of the Boron Group.

Build elements and molecules using neutrons, protons, and electrons. Choices include helium, carbon, oxygen, aluminum, water, and salt.

Students explore the concept of the mole as a measure of quantity. They build spreadsheets that allow them to convert between moles, grams, and atomic mass units for given quantities of everyday items, elements, and simple chemical...
