Classroom Resources: Acids & Bases
1 – 7 of 7 Classroom Resources
Observations, Chemical Change, Chemical Change, Acid, Acid Base Reactions, Chemical Change | Elementary School
In this lesson students will learn that vinegar can react with the Calcium in an egg shell to make it rubbery. First, the students will listen to the teacher read a book about eggs. The teacher will then put an egg in a jar with vinegar and let it set for two days. Students will make a prediction about what they think will happen to the egg, and then together they will investigate the final results.
Observations, Chemical Change, Acid Base Reactions, Indicators | Middle School, Elementary School, High School
In this lesson, students will observe a hidden message while understanding simple acid/base chemistry and indicators.
Acid Base Reactions, Indicators | Middle School, Elementary School, High School
In this demonstration, students will observe a hidden message while understanding simple acid/base chemistry and indicators.
Observations, Acid Base Reactions, Indicators, Chemical Properties | Elementary School
In this lab, students will first determine what colors the cabbage indicator turns in acidic, neutral, and basic solutions.
Chemical Change, Pressure, Conservation of Matter, Reaction Rate, Acid Base Reactions, Chemical Change | Middle School, Elementary School
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 Reactions, Chemical Change, Exothermic & Endothermic | Elementary School
In this demonstration, the teacher will perform two chemical reactions, one will be between acetic acid (vinegar) and sodium bicarbonate (baking soda) and the other will be between Alka-Seltzer and water. Both reactions will produce gas and will be conducted in a Ziploc bag, causing it to inflate. Students will observe the reactions and analyze the results in order to understand indicators of chemical change. Students will also determine that these are both endothermic reactions based on their observations.
Observations, Density, Mixtures, Chemical Change, Chemical Change, Physical Change, Acid Base Reactions, Mixtures | Elementary School
In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.
