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....

Elements don't have fingers, but they have fingerprints! An interactive simulation gives young scientists the opportunity to study orbital changes of an atom and the corresponding spectrum reading. They realize how each atom has a...

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....

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...

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'...

What makes up the air we breathe? Young scientists explore the atoms and molecules in the air. An interactive lesson allows individuals to watch the movement of the particles in the air and change the makeup from a mixture to a...

Explore the excited states of atoms through an interactive lesson. Scholars adjust the initial speed of atoms and observe the kinetic energy of the system as the atoms interact. As they change the initial speed and location of the...

Take a look at some molecules that are so cool, they're polar! Scholars examine the effect polarity has on a molecule's shape and charge. Change up the view and choose between an opaque or transparent molecular surface, complete with...

Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

In this chemistry worksheet, students study the composition of the elements in the periodic table using an interactive website.

Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

What makes helium so Noble, anyway? Explore the bonding properties of helium versus those of hydrogen using an interactive resource. Science scholars manipulate atoms of each element and observe changes in potential energy as the atoms...

In this bonding worksheet, high schoolers take an interactive quiz with 15 multiple choice questions about the VSEPR Theory, bonding, the geometry of molecules, Lewis structures, resonance structures and enthalpy changes.

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...

For this chemistry worksheet, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the atomic...

In this balancing equations worksheet, students use an on line source to answer questions about balanced equations and they write balanced equations for various types of reactions. They balance equations using an on line game that allows...

For this balancing equations worksheet, students use an on line site to practice balancing equations at the beginner level, the intermediate level and the advanced level. They balance four equations for the combustion of different...

In this polymer worksheet, students use an on line site to complete sentences about plastics, their chemical make-up, their uses, their history and information about recycling plastics.

Finally, an electronegativity resource your class will be strangely drawn to! Skilled scientists manipulate interactive puzzles to gain an understanding of common electronegativity values. The great thing? You can conduct the lesson...

Explore how changing the numbers of protons, neutrons, and electrons affect the type of atom.

Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
