  Chemical Change, Chemical Change, Acid Base Reactions, Observations | Middle School, High School

  Lab: How do Sinkholes Form? Mark as Favorite (12 Favorites)

  In this lab students will learn how acidic groundwater reacts with limestone, causing it to erode. Sinkholes form when eroded limestone underneath the surface of the earth can no longer support the ground above it. Students will test how acid reacts with a variety of rocks and determine which rocks would be best to build a city on top of in order to reduce the chance of sinkholes forming.

  Titrations, Indicators, Acid Base Reactions, Stoichiometry, Percent Composition | High School

  Lab: The Egg-straordinary Issue Mark as Favorite (34 Favorites)

  In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.

• 

  Acid Base Reactions, Stoichiometry, Limiting Reactant | High School

  Lab: Fizzy Drink Mark as Favorite (24 Favorites)

  In this lab, students will learn the properties of acid and bases while applying the principles of stoichiometry to calculate the amount of base needed to neutralize an acid completely and produce a bubbly drink.

• 

  Titrations, Acid Base Reactions | High School

  Lab: Vinegar Quality Control Mark as Favorite (8 Favorites)

  In this lab, students will perform a titration of a vinegar sample to determine if it is it close to the concentration claimed on the bottle.

• 

  Titrations, Equivalence point, Indicators, Acid Base Reactions, Chemical Change, Salts, Molarity, Reaction Rate, Order of Reaction , Error analysis | High School

  Lab: Titration Lab with Kinetics Mark as Favorite (4 Favorites)

  In this lab, students calculate the molarity of an unknown using a titration and also by solving for a dilution.

• 

  Combustion, Chemical Change, Catalysts, Acid Base Reactions, Chemical Change | High School

  Demonstration: Stop & Go Gases Mark as Favorite (3 Favorites)

  In this demonstration, students will witness the ability of carbon dioxide to extinguish a flame and oxygen to feed a flame.

• 

  Heat of Neutralization, Acid Base Reactions | High School

  Lab: Heat of Neutralization Mark as Favorite (0 Favorites)

  In this lab, students carry out an acid base reaction to calculate the heat of neutralization.

• 

  Acid Rain, Acid Base Reactions, Chemical Change | High School

  Lab: Seeing the Effects of Acid Rain Mark as Favorite (5 Favorites)

  In this lesson, students will prepare an environment and make acid rain to see how the acid rain effects the items in the environment.

• 

  Reaction Rate, Reaction Rate, Acid Base Reactions | Middle School, High School

  Lab: Plop, Fizz: How to Affect the Rate of a Chemical Reaction Mark as Favorite (11 Favorites)

  In this lesson, students will react Alka-Seltzer tablets with water. By varying the temperature of the water, particle size of the Alka-Seltzer, and concentration of the Alka-Seltzer they can see the effect on the rate and strength of the chemical reaction.

• 

  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.

• 

  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.
