How Atoms Work
High schoolers analyze the way atoms function and how they combine to form molecules and various compounds. Using a software program, they create a diagram of an atom and write a summary about their functions. They complete a worksheet...

Activity #5 Environmental Effects
Learners explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...
Curated OER
Atomic Structure and Quantum Theory
Students are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory
Curated OER
The Mole
Young scholars explore the concent of using the mole to solve problems related to counts small particles of matter. Students work individually and in groups to complete conversions of substances from moles to matter.
Curated OER
Energy Levels and Electron Configurations
Twelfth graders investigate the proper filling order of electrons in the energy levels of an atom. They practice how to "read" these occupied energy levels as electron configurations and demonstrate their understanding through creative...
Curated OER
The Chemistry of Life
Students study atoms and chemical compounds. They identify certain elements essential to human health, describe physical and chemical properties of water, and name four types of polymers unique to all life forms. They explain how each...
Curated OER
The Nature of Matter
Students compare and contrast how the theory of atomic structure has changed over time. They explore how different people have contributed to our knowledge of the atom and its structure. Students identify how matter is made of discrete...
Curated OER
The Ghost Particle
Students collect evidence to make inferences about a object hidden inside a sealed box. They think critically and logically to raise questions. Students identify questions that can be answered through investigation. They formulate and...
Curated OER
Matter
Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.
Curated OER
The Causes of Differences in Density
Learners explore how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Learners draw models of the demonstration and explain what happened.
Curated OER
The Causes of Differences in Density
Students explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence to...

Lesson Plan with Technology - Introduction to Elements and Symbols
Students use a computer program to study elements and the periodic table. They follow the directions on the computer program, and answer the questions presented. The program is self scoring, and students may print a certificate that...

TE Activity: Build a Charge Detector
Students examine how electrical force takes place between two objects by building an electroscope. They apply the electroscope to determine an objects' charge intensity and to see what factors influence electric force.
Curated OER
The Flame and the Atom:
High schoolers investigate the structure of atoms. Students read information about the Rutherford model, the Bohr model, and the Quantum Mechanical model examining each for its scientific validity. They watch a PowerPoint presentation of...
Curated OER
The Story of an Atom
Students work in groups to research an element and how it was discovered. They create an illustration of the element they are researching and create an outline for their presentation. They develop a PowerPoint presentation to share their...
Curated OER
How do protons stick together in a nucleus?
Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.
Curated OER
Men and Women of the Atom
High schoolers 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.
Curated OER
Physical and Chemical Changes in Food
Ninth graders study food mixtures and substances in order to identify atoms, molecules, elements, and compounds and recognize physical changes that take place in foods.
Curated OER
Electron Sqare Dance
Students participate in an Electron Square Dance in which they act the part of atoms. They follow the structure of different atoms suggested by the teacher.
Curated OER
Atomic Structure: The Heart of Matter
Students study the particles of which atoms are made. They define the electron, proton, and neutron and their attributes.
Curated OER
Guess What?! (a lesson about atoms)
Students investigate atoms as particles that make up all matter. They examine the mass of matter.
Curated OER
Atom and Eve
Young scholars research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.
Curated OER
Are You Charged?
Fourth graders study the charges on ions and familiarize themselves with a quick way to remember charges based on location of elements on the periodic table. They complete a worksheet and share their answers with the class.
Curated OER
Matter
Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.
