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

    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.

  • History, pH, Acid & Base Theories, Strong vs Weak | High School, Middle School

    Activity: Acid & Base Guys Video Questions

    In this activity, students will watch a video about the history of acids and bases. They will learn about the evolution of these theories, from Lavoisier to Arrhenius, Bronsted-Lowry, and Lewis.

  • Reaction Rate, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School

    Lab: Bath Bomb Chemistry!

    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.

  • Interdisciplinary, pH, Indicators | High School, Middle School

    Lab: Exhaling Acid

    In this lab students will observe how increased carbon dioxide levels lead to a build-up of acidic conditions.

  • Identifying an Unknown, Indicators | High School, Middle School

    Lab: Indicators of Acids and Bases

    In this lab, students will use various indicators to identify unknown (clear) solutions as acidic, basic, or neutral.

  • pH, Indicators | High School, Middle School

    Lab: Cellular Respiration and pH

    In this lab, students learn how a pH indicator can be used to detect the presence of CO2 when they exhale.

  • History, pH, Acid & Base Theories, Strong vs Weak | High School, Middle School

    Video: Acid & Base Guys Video

    This video tells the story of how the definition of acids and bases has evolved from Lavoisier, to Arrhenius, Bronsted-Lowry, and Lewis.

  • Chemical Change, pH, Acid & Base Theories, Strong vs Weak, Mixture, Salts, Ions, Conductivity | Middle School

    Lesson Plan: Why Drink Gatorade?

    In this lesson, students will test different flavors of Gatorade and other liquids to investigate acids and bases. This will take several days unless students already know about acids and bases.

  • Chemical Change, Physical Change, pH, Identifying an Unknown, Acid Base Reactions | Middle School

    Lab: Is It a Hoax

    In this lab, students will perform tests on the physical and chemical properties of different substances to determine the identity of the unknown.

  • Melting Point, Freezing Point, Phase Changes, Physical Change | Middle School

    Lesson Plan: Stearic Acid

    In this lesson, students investigate how stearic acid undergoes a phase change from solid to liquid and back from liquid to solid. Temperature readings will be collected at one-minute intervals once the acid melts, the heat escapes, and the acid cools. Students are introduced to the idea that energy loss does not always result in a continuous temperature drop.

  • Indicators | Middle School, Elementary School, High School

    Demonstration: Secret Message

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

  • Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School, Elementary School

    Lab: Rocket Challenge

    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 | High School, Middle School

    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.

  • pH, Indicators | Middle School, High School

    Lab: Detecting pH of Commonly Used Acids and Bases

    In this lab, students will use their knowledge of acids and bases to determine the acidity and basicity of every day items by measuring pH using several different methods for determination. Indications of pH may be determined using red & blue litmus paper, pH strips, and pH probes or pH meters.

  • Chemical Change, Gas Laws, Pressure, pH, Acid & Base Theories, Indicators, Solubility Rules | Middle School

    Lesson Plan: Chemistry of Pop Rocks

    In this lesson, students will determine the pH of several liquids with litmus paper or a pH probe. Next, students will explore how pH affects the production of gas with Pop Rocks. Students will also investigate how Charles’ Law affects Pop Rocks. Finally, students will design their own experiment with Pop Rocks.

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

    Demonstration: Another Secret Message

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

  • Acid, pH, Indicators, Chemical Properties | Middle School

    Lab: Acid & Base

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

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

    Demonstration: Inflating a Balloon with Chemistry

    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.
