101 – 107 of 107 Classroom Resources

• 

  Observations, Inferences, Scientific Method | High School

  Demonstration: Observations vs. Inferences Mark as Favorite (5 Favorites)

  In this demonstration, students will learn the the difference between observation and inferences.

• 

  Observations, Scientific Method, Experimental Design, Error Analysis | High School

  Lab: Airplanes Mark as Favorite (6 Favorites)

  In this lab, students will design a procedure to test for the intended outcome of a longest flight.

• 

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

  Lab: Chemical Reactions & Equations Mark as Favorite (49 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.

• 

  Sublimation, Density, Observations | High School, Middle School

  Lab: Dry Ice (High School) Mark as Favorite (30 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 (72 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.

• 

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

  Demonstration: Catalyst in Motion Mark as Favorite (17 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.
