What Are Atoms and Isotopes?

Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an atom's...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

In this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each and...

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

Altering the subatomic nature of an atom affects its properties. The video illustrates the idea of an isotope using Carbon-12, Carbon-13, and Carbon-14 as examples. 

Some isotopes are unstable, or radioactive, meaning they will decay over time and turn into another isotope or stable element. In the interactive simulation, participants manipulate elements to create isotopes and gather information....

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

Skeletons may not be able to speak, but they can still tell us a lot. High schoolers watch a short video about the ways biological anthropologists can use a skeleton's bone structure to determine age, gender, place of birth, and social...

Feeling a little uncertain about your materials for teaching the quantum mechanical model of the atom? Here is an interactive that will help! Chemistry and physics scholars alike will benefit from a simple resource that illustrates the...
