Classroom Resources: Acids & Bases
1 – 19 of 19 Classroom Resources
Chemical Change, Chemical Change, Acid Base Reactions, Observations | Middle School, High School
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.
Reaction Rate, Reaction Rate, Chemical Change, Acid Base Reactions | Middle School
In this lab, the students will work in cooperative groups to investigate how to make a scented, effervescent bath bomb and explore the chemistry needed to create them. Groups will test a variety of different variables in order to compare the reaction rate of each sample. Students will use the results to determine which variables are optimal for making and using bath bombs.
Titrations, Indicators, Acid Base Reactions, Stoichiometry, Percent Composition | High School
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
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.
Chemical Change, Chemical Change, Observations, Acid Base Reactions, Chemical Change, Acid | Elementary School
In this lesson students will learn that vinegar can react with the Calcium in an egg shell to make it rubbery. First, the students will listen to the teacher read a book about eggs. The teacher will then put an egg in a jar with vinegar and let it set for two days. Students will make a prediction about what they think will happen to the egg, and then together they will investigate the final results.
Titrations, Acid Base Reactions | High School
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.
Physical Change, Chemical Change, Identifying an Unknown, Acid Base Reactions | Middle School
In this lab, students will perform tests on the physical and chemical properties of different substances to determine the identity of the unknown.
Titrations, Equivalence point, Indicators, Acid Base Reactions, Chemical Change, Salts, Molarity, Reaction Rate, Order of Reaction , Error analysis | High School
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
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
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
In this lesson, students will prepare an environment and make acid rain to see how the acid rain effects the items in the environment.
Chemical Change, Pressure, Reaction Rate, Acid Base Reactions, Chemical Change, Conservation of Matter | Elementary School, Middle School
In this lab, students will have the opportunity to construct a rocket, with the challenges of both designing it and preparing a chemical reaction for its “fuel” in order to propel the rocket over the furthest distance. Students will investigate available materials, quantities and ratios during allotted planning and testing phases. Student will record their plans, modifications and designs during the process. The lab will culminate with a competition amongst students to see whose rocket will travel the longest distance.
Reaction Rate, Reaction Rate, Acid Base Reactions | Middle School, High School
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.
Chemical Change, Exothermic & Endothermic, Acid Base Reactions, Chemical Change | Elementary School
In this demonstration, the teacher will perform two chemical reactions, one will be between acetic acid (vinegar) and sodium bicarbonate (baking soda) and the other will be between Alka-Seltzer and water. Both reactions will produce gas and will be conducted in a Ziploc bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical change. Students will also determine that these are both endothermic reactions based on their observations.
Indicators, Chemical Properties, Observations, Acid Base Reactions | Elementary School
In this lab, students will first determine what colors the cabbage indicator turns in acidic, neutral, and basic solutions.
Indicators, Acid Base Reactions | High School, Elementary School, Middle School
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
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
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
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.
