  • Classification of Reactions, Chemical Change, Solubility Rules, Net Ionic Equation | High School

    Access is an AACT member benefit. Demonstration: Precipitation Reaction Mark as Favorite (45 Favorites)

    In this demonstration, students will observe a precipitation reaction. Students will create several particle diagrams in order to describe and fully understand what is occurring on the atomic level during the chemical reaction.

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

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. Lab: Chemistry in a Bag Mark as Favorite (89 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.

  • Chemical Change, Chemical Change | Elementary School

    Access is an AACT member benefit. Lab: Teeth Eggsperiment! Mark as Favorite (1 Favorite)

    In this lab students will observe and analyze how different drinks can stain an egg’s shell. They will then associate the results with how these drinks can stain their teeth.

  • Chemical Change, Chemical Change, Physical Change, Observations | Elementary School

    Access is an AACT member benefit. Demonstration: Make a Cake! Mark as Favorite (1 Favorite)

    In this demonstration, students will learn about chemical reactions by observing the differences when 4 small cakes are baked. Each recipe will differ slightly in that one important ingredient will be left out in 3 of the 4 mixtures. Students will observe and discuss what happens when things are missing or left out of a mixture and how that effects the chemical reaction.

  • Concentration, Solute & Solvent, Chemical Change | Elementary School, Middle School

    Access is an AACT member benefit. Demonstration: Soft Eggs Mark as Favorite (2 Favorites)

    In this demonstration, students will first observe a reaction between vinegar (acetic acid) and an egg shell (calcium carbonate) to produce a naked egg. Using these eggs, student will analyze how certain substances can move through a membrane and also determine if the membrane is affected.
