Welcome to the Science Notes and Projects site, where you’ll find experiments, projects, and notes for all scientific disciplines and educational levels. We write science articles and make all kinds of printable periodic tables and periodic table wallpapers.

Periodic Table with 118 Element Names and Symbols

Here’s the Science Notes periodic table with the official names and data for all 118 elements.

Comprehensive Chemistry Dictionary

Here’s a comprehensive chemistry dictionary. Over time, we’re adding full articles for each term.

How to Make Glowing Jewelry

Here’s a project that combines art and science to make rings that glow in the dark. These rings look like quartz or crystal in the light but glow brilliantly in the dark.

Lists of Things That Glow

Here are two lists for you. One covers things that glow under black light (fluorescent or phosphorescent), while the other covers things that glow when the lights go out and it’s truly dark. Some items produce luminescence both ways:

• Things That Glow in the Dark
• Things That Glow Under Black Light

Essential Chemistry Charts and Tables

Sometimes it’s just easier to have a printout of important information. These tables are available as PDF files. You can save these and print them out at your convenience:

• Alphabetical List of the Chemical Elements
• Table of Important Constants
• Rare Earth Elements
• Valences of the Elements
• Electron Configurations of the Elements
• Understand Wedge and Dash Notation

Trigonometry Help at Science Notes

Learn to love the triangle. Trigonometry is one of the scientist’s basic tools in their mathematics toolbox. Here are a couple of useful printable reference sheets with trig relationships, special triangles and trig identities. Got requests for trig or stats content? Let us know. We both have degrees in math.

Periodic Table Trends

Metals, Metalloids and Nonmetals
This periodic table shows the elements and locations of the metals, metalloids and nonmetals. It also lists the common properties of metals, metalloids and nonmetals. You can print out the table the same as any of the periodic tables on the site.

List of Metals
This is a list of the elements considered to be the metal elements along with a periodic table highlighting these elements and their common properties.

List of Metalloids
This is a list of the elements considered to be the metalloid or semimetal elements. It also contains a periodic table highlighting the metalloids and their common properties.

List of Nonmetals
This is a list of all the nonmetal elements, their location on the periodic table and the properties of a nonmetal.
