Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Excited atoms lead to exciting lessons! Learners use heat and light to excite both atoms and molecules. They display their learning in the form of Bohr models depicting the excited state of the atoms.

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...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

Students research the element of carbon, its composition, and the importance of carbon to life on earth. Then they design model mobiles of carbon atoms to demonstrate their understanding of the configuration of protons, neutrons, and...

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...

Need a solid resource for teaching about states of matter? Science scholars go with the flow in a simple interactive that shows how intermolecular attractions determine a substance's phase. Pupils take control of the level of attraction...

A simple activity for introductory chemistry classes is thoroughly explained in this lesson plan. Each individual receives a sealed box containing an unknown object. Inquisitors use indirect evidence to draw conclusions. This activity is...

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...

There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...

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...

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

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...

High schoolers investigate the wavelengths of spectra lines for common atoms. In this atomic emission spectra lesson plan, students use a transformer and diffraction grating to observe the emission spectra of various atoms. They find the...

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...

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.

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...

In this atomic models time line worksheet, students draw a diagram of Democritus, Dalton, Thomson, Rutherford and the Electron Cloud model of the atom.

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...

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...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

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...

In this Bohr model and wave mechanical model worksheet, learners read about the differences between these two models of the atom. Students answer four questions about these models.

How many different molecules can you build? In a simulation, learners make molecules from given atoms. There are numerous collections from which to build three to five molecules from given kits of atoms. Scholars can also view their...
