Welcome to the Science Notes and Projects site, where you’ll find experiments, projects, and notes for all scientific disciplines and educational levels. We make all kinds of printable periodic tables and periodic table wallpapers. Here’s a look at what’s new and some current science projects:

2018 Periodic Table with 118 Element Names and Symbols

Here’s the periodic table with the official names and data for element 113, 115, 117, and 118. Enjoy!

Comprehensive Chemistry Dictionary

Back in the day, I had a huge chemistry dictionary on About.com. Over the years, that dictionary got pruned, yet it’s still helpful to be able to look up unfamiliar chemistry terms. So, I’ve added a comprehensive chemistry dictionary here on Science Notes.

How To Make Glowing Jewelry

Combine Art and Science To Make Glowing Rings

Combine Art and Science To Make Glowing Rings

As some of you know, when I’m not writing about science, I like to make 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… all night long.

Lists of Things That Glow

Yes, I have a fascination with light and color! 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:


Essential Chemistry Charts and Tables

Sometimes it’s just easier to have a printout of important information. While we’ve had periodic tables since forever, here are a couple new additions you may find helpful. These tables are available as PDF files. You can save these and print them out at your convenience:

Please let us know if there are specific tables or charts you’d like to see. We’re happy to add them — just helps to know what you need 🙂

Science Demonstrations and Projects

Here are some of the new projects recently added to Science Notes:

Science Jokes

We’ve added a little humor with a collection of science and math jokes. Spend a little time laughing (or groaning) at the lighter side of science. You’re welcome to post a reply to tell your own science joke!

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 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.

Science Projects

Here are some new science projects, plus some old favorites:

How To Grow Crystals

Chrome Alum

Chrome Alum (Ra’ike)

We’ve got a bunch crystal-growing projects for you. Instructions range from crystals grown with home chemicals to easy lab chemical crystals to try. Here are some recent additions:

Our Very First Periodic Table Wallpaper

This was the first table we added to the site and it’s still one of the most popular. The colors are bright, but not too bright, and the text is easy to read. This one prints quite nicely and looks lovely on a monitor.

      This is a great website for anyone, doesn’t matter what age, and be able to explore the world of Science and learn more about this amazing subject.

      Your work has inspired me to create a program that may help students to be able to learn more about the elements in a visual way. It is an interactive periodic table of elements which can be downloaded and used offline. I was wondering if you would like to possibly feature it on your website when it is completely done (about 95%, just adding finishing touches 😉 …)

      Kind regards

    wonderful stuff, I asked all my kids to sign up and use it to teach my grandkids! Wish they had teachers like you. I enjoy being old and retired so that I can delve into why things work, you know, like the reason that shining light on stuff you spray on blood to make it fluoresnce happens. double bonds that get excited by visible light. No one to look at me like I am an alien because I keep asking why all the way down to the quantum level. That is what little kids really want to know, deep knowledge whys! You and the great books I can buy used online were what I used to seek in Leery’s, now gone, in Philly.

    I was so proud of myself when I created that table. It was my first attempt to create a Periodic Table in Illustrator.
    Of course, once you publish something, you start to see all the little errors. The rhenium atomic weight is only one of many on that table.
    I’ve addressed all of these errors in the 2015 Edition of this table.

      Todd, the table is absolutely genius !! For all students it will be of great help to visually be able to see and remember relationships within the table. Cheers to your inspiration!! As it will help others in ways to study and make connections so much easier. Wish I had had it in my chemistry class????

    You’re welcome to use the table for printed material, with acknowledgement, so long as the table is not posted one a website. Thanks!
