  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.

  Lab: Bath Bomb Chemistry! Mark as Favorite (7 Favorites)

  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.

  Lesson Plan: Why Drink Gatorade? Mark as Favorite (0 Favorites)

  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.

• 

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

  Lab: Is It a Hoax Mark as Favorite (4 Favorites)

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

• 

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

  Lesson Plan: Stearic Acid Mark as Favorite (2 Favorites)

  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.

  Lab: Rocket Challenge Mark as Favorite (3 Favorites)

  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

  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.

  Lab: Detecting pH of Commonly Used Acids and Bases Mark as Favorite (4 Favorites)

  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.
