1 – 12 of 12 Classroom Resources

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

### Access is an AACT member benefit. Lab: How do Sinkholes Form?

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

### Access is an AACT member benefit. Lab: The Egg-straordinary Issue

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

### Access is an AACT member benefit. Lab: Fizzy Drink

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

### Access is an AACT member benefit. Lab: Vinegar Quality Control

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

### Access is an AACT member benefit. Lab: Titration Lab with Kinetics

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

### Access is an AACT member benefit. Demonstration: Stop & Go Gases

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

### Access is an AACT member benefit. Lab: Heat of Neutralization

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

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

### Access is an AACT member benefit. Lab: Plop, Fizz: How to Affect the Rate of a Chemical Reaction

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

### Access is an AACT member benefit. Demonstration: Another Secret Message

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

### Access is an AACT member benefit. Lab: Alka-Seltzer & Gas Solubility

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

### Access is an AACT member benefit. Lab: Acid/Base Stoichiometry

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.
