  Lesson Plan: Comparison of Vitamin C in Juice Drinks Mark as Favorite (8 Favorites)

  In this lesson, students will use a color-changing indicator called indophenol and a simplified titration method to determine if vitamin C is present in a variety of store-bought juices. The indicator solution will turn from dark blue to colorless once all the indophenol has reacted with vitamin C in the juices. Students will count how many drops of juice it takes to produce this color change in a 5-mL sample of indicator solution. The greater number of drops it takes to cause the color change, the less vitamin C is present in each drop. They will use their data to compare the relative amounts of vitamin C in the juices to a solution prepared from a vitamin C tablet.

  Lesson Plan: Cheesy Science Emergency Lesson Mark as Favorite (3 Favorites)

  In this lesson, students will learn about pH, acids, bases, enzymes, and chemical reactions through reading the highly rated ChemMatters article, Cheesy Science. The lesson includes several activities to help promote literacy in the science classroom related to the reading. This lesson could be easily used as an emergency lesson plan for a substitute teacher, as most of the activities are self-guided.

  Lab: A Comparison of Two Chemical Reactions Mark as Favorite (41 Favorites)

  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

  Lab: How do Sinkholes Form? Mark as Favorite (41 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.
