  Lab: Chemical Weathering of Rocks

  In this lab, students will explore simulated reactions that contribute to chemical weathering of certain rocks as it appears in nature.  They will compare the effects of two different chemicals as it contacts various rock and mineral samples.

  Lab: My Pennies

  In this lab, students will investigate how an acidic, vinegar based solution can help to get “dirty” pennies clean. Students will observe chemical change and investigate real-world connections to this lab.

  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.
