The Structure of Atoms

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this resource would...

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements, this...

Young scholars discuss how small they must cut something before it is no longer fundamentally the same. An online activity challenges and engages pupils in learning about the periodic table. Two hands-on activities cover elements and...

Wow, an experiment that allows the class to participate in a missile war! Pupils discuss Thomsons's theory of cathode rays and simulate Rutherford's historical experiment to learn about atomic structure. They conclude this fourth lesson...

A fuel cell is where the jailer keeps gas guzzlers. Scholars review chemical reactions, chemical bonds, and chemical structure in order to apply these concepts. Participants construct fuel cell kits, using electrolysis to run the car and...

Explore the composition of atoms with this sweet physical science activity. Using different colored gumdrops to represent protons, neutrons, and electrons, young scientists create models of lithium atoms before answering a series of...

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

An engaging simulation encourages scholars to discover if the Bohr model of an atom is correct. They shoot light at a hydrogen atom in various conditions to see which of the many models is plausible or inadequate. 

Using a massive cartoon blueberry as an atom model, an animated astronaut describes an atom's anatomy and the density of its nucleus. After showing this featurette, you can have young physical scientists construct atom models. Also, be...

From ancient Greek philosophers to early American Quakers, people have sought to understand the composition of matter for millennia. Follow along with this video as it explores the long scientific journey that eventually led to the...
