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...

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...

Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

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....

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.

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

For this nucleus of an atom worksheet, students answer 19 multiple choice questions about the structure of the atom, radioactive decay, isotopes and half life.

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Up and atom! After labeling the parts of an atom, young chemists answer 16 diagram-based questions that deal with protons, neutrons, electrons, and atomic number.

Did you know the word energy comes from energeia, a Greek word? Introduce learners to the four types of potential energy, five types of kinetic energy, and energy transformation with a presentation about where we get our energy and...

This science presentation focuses on the elements in the periodic table. It begins with the parts of an atom, explaining atomic mass and atomic number, valence electrons, and isotopes. Then it moves on to discuss various ways of...

Learners roll dice in order to simulate the probability of locating an electron in a certain region around the nucleus.

This PowerPoint is a comprehensive review of all the facts related to an atom's basic structure and function. What makes this unique is that it is geared toward an audience of junior geologists. After introducing the periodic table of...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

This PowerPoint provides a complete recap of all the information needed for a unit on elements and the periodic table. The seventy slides cover the basic notation of elements, energy levels and ionization energies. The trends in the...

Tired of blowing up countless balloons to illustrate orbital shapes around an atom? Give your lungs a break and use an interactive instead! Learners observe s, p, d, and f orbitals through the first four energy levels using hydrogen as a...

In this nucleus and radioactivity worksheet, students collect class data and the students represent radioactive atoms decaying. They plot their data and answer two questions about the results. They solve seven problems given the...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....
