Lab: A Comparison of Two Chemical Reactions
In this lab, students will perform two chemical reactions, one between acetic acid and sodium bicarbonate and the other between the citric acid and the sodium bicarbonate in an Alka-Seltzer tablet when dissolved in water. Both reactions will produce gas while reacting in a closed plastic sandwich bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical changes, heat flow, and factors that affect reaction rates

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

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. They will also be introduced to the concept of catalysts. This demonstration could also be used as an opportunity to practice writing and balancing equations and classifying chemical reactions.

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.
