Rings and golden nuggets contain the element gold, but how small can you break it down before it is no longer considered gold? A helpful presentation explains the basics about atoms, elements, and isotopes through a presentation.

How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...

A color-coded periodic table identifies organic elements, major minerals, and trace elements. Oxidation states are highlighted and types of chemical bonding are annotated. The electron energy level chart is explained. Though not all of...

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

When physical science classes are becoming familiar with the periodic table of elements, you can use this set of printable cards to help them memorize some of the members of the metals, metalloids, and nonmetals groups. There are 24...

How random is random? Demonstrate the different random sampling methods using a hands-on activity. Pupils use various sampling techniques to choose a random sample of elements from the periodic table. They use the different samples to...

Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

A really good worksheet on the periodic table of the elements is here for you. Learners must color in the elements listed in the worksheet that are needed to make a light bulb. They then answer questions about each of the elements.

What a cute approach to chemical bonding! Atoms all have human names and are attending at a dance. Who will pair up with whom? By reading the characteristics, and not the element name, chemistry whizzes figure out the bonding pairs....

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, learners build molecules based on the chemical formulas of common compounds.

Students investigate the properties of elements and periodicity. In this periodicity lesson plan, students observe a bag of 'elements' which are different fruits and classify them in groups and periods, show the periodic relationships...
