Students investigate the periodic table, the structure of the atom and the subatomic particles. In this periodic table lesson plan, students complete 5 activities in order to better understand atoms and the periodic table. They use...

In this atom worksheet, students read about the parts of the atom and how atoms combine into molecules and compounds. Students learn how to read a periodic table. This worksheet has 20 fill in the blank and 10 matching questions.

In this early history of the atom worksheet, students answer 4 questions about Thomson's Plum Pudding model of the atom and Rutherford's experiment that led to the understanding of some of the structures of the atom.

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...

Where does an electron reside? Chemistry scholars determine an electron's "address," that is, what orbital it can be found in. This resource is both instructional and practical,  providing a thorough explanation of energy levels and...

Students explain scientists' ideas about the structure of the atom over the last century. They develop a pictorial history of the changing ideas about the atom and write a caption describing the scientific thinking behind the model.

Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

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...

Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.

Have you reached your breaking point in looking for great resources that illustrate bond energy? Demonstrate the potential energy changes that occur when polar and non-polar bonds are broken with a stimulating simulation. Pupils pull on...

The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...

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...

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.

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...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

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...

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

In this atom worksheet, students read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They answer 30...

The VSEPR Model of molecular structure is exhibited through this series of slides. The step-by-step process is listed, and then examples are provided. The graphics give a visual display of the spatial relationship between the atoms of...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson plan. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common...

What goes into a museum display? A secondary-level STEM project prompts groups to design a museum display for the Tech Museum of Innovation. They create an analogous, interactive model illustrating a science concept to complete the...

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

Delve into the world of quantum mechanics by viewing this PowerPoint. Chemistry novices learn about electron energy and shells, and they practice listing electron configuration for different atoms. Because this presentation provides...
