I'm so cool! No, you're exothermic. This thermodynamics lab unit includes an introduction, teacher demonstrations, six labs that students rotate through each class day, homework assignments, application of knowledge, and assessments....

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments demonstrating their properties, this resource is...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Several radioactive concepts are explained with the help of animated atoms, complete with their own facial expressions. As physical science pupils watch, they learn about gaining or losing atomic particles, alpha and beta particles, and...

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...

A variety of activities get new chemists exploring the elements. The highlight is a song shown via online video by Tom Lehrer called, "The Elements." Offer bonus points to anyone who can memorize this tune! Other various interactive...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having learners drop a pencil on a sheet of...

In this National Olympiad exam worksheet, chemistry apprentices answer sixty multiple choice questions including general chemistry topics such as atomic structure, gases, problem solving, writing and balancing equations and solutions....

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

Primo Levi wrote a collection of short stories comparing his life from Italy to Auschwitz to elements in the periodic table. Pupils read an excerpt from his book and research the characteristics of various elements. Then, they make a...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

The hydrogen in your body is exactly the same as the hydrogen in the sun. The video explains just how small an atom is and offers comparisons, such as the one above, to help facilitate understanding. It also presents the current model of...

Why is the periodic table arranged the way it is? As pupils complete the electron configuration of the first 20 elements, they see the relationship to the rows and columns in the periodic table. The video instructor highlights these...

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 table.

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Scholars build specific elements by creating a model of its atomic structure. Objects they can include are protons, nuetrons, electrons, orbits, clouds, charge, and mass number. Simulation ends with questions to challenge individuals'...

Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...

Just because we can't see an atom doesn't mean we can't study it! The video examines the makeup of the atom. It explains the roles of the protons, neutrons, and electrons. 

Share this video with your class and explore the conditions that make covalent bonding possible. Examining the complex series of attractive and repulsive forces that exist between atoms, this video explains how at just the right distance...
