  Chemical Change, Physical Change, Observations, Chemical Change, Interdisciplinary, Acid, Chemical Change | Middle School

  Lab: Break It Down! Mark as Favorite (4 Favorites)

  In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.

• 

  Indicators, Acid Base Reactions | High School, Elementary School, Middle School

  Demonstration: Another Secret Message Mark as Favorite (2 Favorites)

  In this demonstration, students will observe a hidden message while understanding simple acid/base chemistry and indicators.

• 

  Mixtures, Mixture, Chemical Change, Physical Change, Observations, Density, Acid Base Reactions, Chemical Change | Elementary School

  Lab: Analyzing a Lava Lamp Mark as Favorite (1 Favorite)

  In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.

• 

  Solubility, Acid Base Reactions, Titrations, Indicators, Intermolecular Forces, Concentration, pH | High School

  Lab: Alka-Seltzer & Gas Solubility Mark as Favorite (7 Favorites)

  In this lab, students will use a reaction to investigate temperature and the solubility of carbon dioxide and will use a neutralization reaction and an indicator to verify the amount of carbon dioxide produced at each temperature.

• 

  Limiting Reactant, Acid Base Reactions | High School

  Lab: Acid/Base Stoichiometry Mark as Favorite (3 Favorites)

  In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.

• 

  Titrations, Limiting Reactant | High School

  Lab: Acid-Base Mole Ratio Mark as Favorite (0 Favorites)

  In this lab, students study several concepts, including acid-base reactions, limiting reactants, and stoichiometry, by observing the contained reaction of acetic acid (diluted vinegar) with sodium hydrogen carbonate (baking soda) in an unconventional, cost effective titration.

• 

  Indicators, Acid, Chemical Properties | Middle School

  Lab: Acid & Base Mark as Favorite (0 Favorites)

  In this lab, students are given four unknown liquids and must identify whether they are acids or bases.

• 

  Acid & Base Theories | High School

  Project: Acid Base Creative Letter Mark as Favorite (5 Favorites)

  In this project, students will compare and contrast the properties of acids and bases and define pH.

• 

  Strong vs Weak, Titrations | High School

  Lab: Acid Base Reactions Mark as Favorite (1 Favorite)

  In this lab, students will witness a reaction between an acid and base. One will be strong, and the other may be weak or strong--it's up to them to determine.

• 

  Chemical Change, Chemical Change, Observations, Acid, Chemical Change | Elementary School

  Lab: My Pennies Mark as Favorite (2 Favorites)

  In this lab, students will investigate how an acidic, vinegar based solution can help to get “dirty” pennies clean. Students will observe chemical change and investigate real-world connections to this lab.

• 

  Indicators, Le Châtelier's Principle | High School

  Demonstration: Milk of Magnesia Magic Mark as Favorite (19 Favorites)

  In this demonstration, students will observe a color change in a milk of magnesia solution as vinegar is added.

• 

  Chemical Change, Observations, Mixture, Chemical Change | Elementary School, Middle School, High School

  Demonstration: Inflating a Balloon with Chemistry Mark as Favorite (4 Favorites)

  In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.
