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.
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.
Observations, Chemical Change, Inferences, Interdisciplinary, Chemical Change | Elementary School
In this lesson, students will extract DNA from strawberries and analyze evidence to figure out who perpetrated a petty crime.
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, Mixture | 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.
Observations, Chemical Change, Chemical Change, Acid, Chemical Change | Elementary School
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.
Observations, Chemical Change, Chemical Change, Mixture | High School, Middle School, Elementary School
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.
