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...

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Chemistry classes will appreciate this color-coded, single-page reference sheet for The Standard Model of particle physics. It is divided into two main sections: elementary particles and compound particles, both with their antiparticles....

Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons,...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

First graders discuss, at their level, the concept of elements making up all matter. They discover the story of Dimitri Mendeleev and his discovery of the Periodic Table of the Elements. They locate and color some of the most common...

Students pretend they are water droplets traveling through the water cycle. Using their text, they discover the steps in the cycle and the different paths water can take. They write a report about their journey through the water cycle...

In 1879, Sir William Crookes discovered the fourth state of matter, plasma. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,...

Students investigate the scientists that have contributed to the modern day atomic theory. They conduct Internet research, develop a table, record data, and produce a webpage about their selected scientist.

Atomic theory as a philosophical study was explored even by the Ancient Greeks. The knowledge of atoms was developed in the 17th century.  This PowerPoint explains how by the 1940's, splitting of the atom was discovered and since...

Name is Bond, covalent bond. Through readings and answering questions, classes explore the different types of chemical bonds, their characteristics, valence shell electron pair repulsion theory, and atomic orbitals.
