Curated OER
Chemical Reactions
In this reactions worksheet, students state the differences between a coefficient and subscript and an exothermic and endothermic reaction. Students review the different types of reactions. This worksheet has 13 short answer questions.
Curated OER
Studying with Chemical Compounds
Students create a foldable to help them remember topics on chemical compounds. In this physical science lesson plan, students differentiate ionic and covalent compounds. Given certain compounds, they identify whether it's ionic or covalent.
Curated OER
Properties of Matter
Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...
Curated OER
Liquids and Solids
Students describe the properties of solids and liquids, and explain how a semiconductor works. In this atom lesson students demonstrate the bonding properties of carbon and silicon.
Curated OER
Simple Chemical Equations
Eighth graders interpret the chemical symbols and shorthand used for molecules and equations. Through guided practice, 8th graders work to decipher and interpret the symbols for chemical equations. An opportunity for independent...
Curated OER
Can Chromatography Separate A Pigment?
High schoolers separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...
Alabama Learning Exchange
Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
Curated OER
Doing Lewis Dot Diagrams
Students observe the periodic table and draw the Lewis Dot Diagram. In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they learned.
Curated OER
EGG-cellent POLYMER PACKAGING DESIGN
Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...
Curated OER
Micro-Magic With Sticky Ions
Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.

Middle School Chemistry: Energy Levels, Electrons, Ionic Bonding
Students discover that ionic bonding occurs when electrons are transferred from one atom to the other and not shared as in covalent bonding.
American Chemical Society
Middle School Chemistry: Represent Bonding With Lewis Dot Diagrams
Students draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.
American Chemical Society
Middle School Chemistry: Chapter 4: The Periodic Table and Bonding
Six middle school chemistry lessons about the periodic table and bonding complete with handouts and animations.
