Classroom Resources: Acids & Bases

1 – 5 of 5 Classroom Resources

• 

  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.

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

  Chemical Change, Acid & Base Theories, Indicators, Solubility Rules, Gas Laws, Pressure | 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.

  Lab: Break It Down!

  In this lab, students will examine the physical and chemical changes that take place within a landfill by composting leftover fruits and vegetables from their lunches. They will also record pH and temperature measurements during the process.

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