Flambe Elements
Eighth graders discuss atoms and electrons as well as atoic structure. They view atomic structure via the computer. Students watch a demonstration in which the teacher demonstrates glass tubing turning yellow in a Bunsen Burner flame....
Curated OER
Solids, Liquids, and Gases
Students investigate and explore the three states of matter. They read and discuss the NASA article "The Engine That Does More," identify examples of each state of matter, and as a class complete a section of two worksheets. They...
Curated OER
Reaction Reasoning
Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur. In this matter lesson students divide into groups and complete a lab experiment.
Curated OER
Physical Science Project-Atom
Fifth graders investigate atoms. In this atom lesson, 5th graders investigate the parts of an atom. Students explore atom numbers and determine the number of electrons is in each atom.

Let's Break the Particles
Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction or...
Curated OER
Atomic Structure
Students list the names and symbols of common elements. They describe the present model of the atom. Students describe how electrons are arranged in an atom. They identify quarks as particles of matter that make up protons and...
Curated OER
Can You Get A Charge Out Of Matter?
Students observe and demonstrate how objects can be charged positively and negatively and how static electricity works. They observe a teacher-led demonstration, and in small groups rotate through various static electricity activities,...
Curated OER
Men and Women of the Atom
Students 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
Matter And Its Changes
Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.
Curated OER
Classifying Matter Game
Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.
Curated OER
Atoms, Kinetic Theory, Solids and Fluids
Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.
Curated OER
How Can You Study Things You Can’t See Like: Atoms?
Students simulate how scientists studied things they can't see like atoms. For this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.

Understanding Elements
Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...
American Chemical Society
Identifying an Unknown Liquid
Liquids are what's the matter with the lesson! Learners investigate properties of different liquids as they interact with various types of paper. They then use their observations to identify a mystery liquid to finish the sixth lesson in...
Curated OER
Solids, Liquids, and Gases
First graders explore the properties of matter. In this states of matter instructional activity, 1st graders conduct scientific investigations that require them to mix, cool, and heat objects in order to observe changes in the properties...
Curated OER
Model Mania
Eighth graders study the conservation of matter. In this chemical reaction lesson students examine what happens during a chemical reaction and complete a lab activity.
Curated OER
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
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
The Mole
Students 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
How do protons stick together in a nucleus?
Pupils 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
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 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
Crystals: What Are They and What Holds Them Together
Students are introduced to the characteristics of crystals and what keeps them together. Using the Periodic Table, they examine the various elements and develop a model of an atom. In groups, they place sugar and salt in petri dishes...
