  Physical Properties, Chemical Properties | High School

  Lesson Plan: Engineering a Vehicle Mark as Favorite (7 Favorites)

  In this lesson students will take on the role of a Ford Motor Company engineer and evaluate the potential use of carbon fiber technology for use in the automotive industry.

  Chemical Change, Activity Series, Redox Reaction, Chemical Change, Physical Change | High School

  Demonstration: Understanding the Discrepant Reactivity of Copper in the Presence of Strong Acids Mark as Favorite (9 Favorites)

  In this demonstration, students practice their observation skills during the additions of different acids to two test tubes containing copper. The activity is structured to allow students to make thoughtful remarks about what they observe, using rich indicators of both chemical and physical properties and changes. In subsequent lessons on new concepts, students can reflect back on their observations to rationalize the discrepant results of the reactions in the demonstration.

  Molecular Structure, Intermolecular Forces, Physical Properties | High School

  Lab: Solubility Plays a Role: Making Seitan from Flour Mark as Favorite (14 Favorites)

  This lab offers insight into a practical aspect of solubility and demystifies a common ingredient, wheat flour. In this lab students will read about the composition and observe some properties of whole wheat flour by preparing seitan, a vegetarian meat substitute made from the glutenin and gliadin proteins in flour. Gluten, formed from the interaction of the aforementioned proteins, has a unique property of elasticity.

• 

  Balancing Equations, Chemical Change, Observations | High School, Middle School

  Lab: Chemical Reactions & Equations Mark as Favorite (53 Favorites)

  In this lesson, students will observe a series of reactions, make observations, and then write balanced chemical equations to chemically describe what they observed.

• 

  Density, Combustion, Lab Safety | High School

  Demonstration: Density of Gases and Particle Diagrams Mark as Favorite (9 Favorites)

  In this demonstration, students will observe the teacher carry out two combustion reactions. First the teacher will burn a small sample of propane gas in a beaker. Next the teacher will burn a small sample of methane gas. Students will create particle diagrams in order support their explanation and model their observations as they improve their understanding of gas density.

• 

  Sublimation, Density, Observations | High School, Middle School

  Lab: Dry Ice (High School) Mark as Favorite (32 Favorites)

  In this lab, students perform several small experiments using dry ice and record their observations.

• 

  History, Physical Properties, Observations, Model of the Atom | Elementary School, Middle School, High School

  Video: Ancient Chemistry Video Mark as Favorite (79 Favorites)

  This video traces the history of chemistry from the discovery of fire, through the various metal ages, and finally to the great philosophers.

• 

  Density, Observations, Measurements | Middle School, High School

  Lab: Penny Boats Mark as Favorite (23 Favorites)

  In this lab, students will explore Archimedes’ Principle and how it relates to density. Each student will be given a piece of aluminum foil and asked to design and build a boat that will hold as many pennies as possible without sinking when placed in water.

• 

  Lab Safety | High School, Elementary School, Middle School

  Activity: What Not to do in the Chemistry Lab Mark as Favorite (117 Favorites)

  In this activity, students will examine a cartoon of a chaotic chemistry laboratory and note the specific behaviors that are dangerous and unsafe in a chemistry laboratory setting. This activity provides an opportunity for teachers to introduce laboratory safety and best laboratory practices and discuss them with their students.

• 

  Classification of Reactions, Chemical Change, Catalysts, Observations | Middle School, High School

  Demonstration: Catalyst in Motion Mark as Favorite (20 Favorites)

  This demonstration allows students to visualize how a catalyst can impact a chemical reaction. Students will also identify the products of a decomposition reaction, as well as determine if the reaction was endothermic or exothermic based on their observations.

• 

  Lab Safety | High School, Middle School

  Demonstration: Lab Safety Mark as Favorite (35 Favorites)

  In this demonstration, students discuss laboratory safety and observe corn starch being ignited.

• 

  Chemical Change, Conservation of Mass, Chemical Change, Physical Change | Middle School, High School

  Lab: Chemistry in a Bag Mark as Favorite (96 Favorites)

  In this lab, students will observe and identify chemical and physical changes contained inside a plastic bag. Students will also use this lab to understand the Law of Conservation of Mass.
