Discovering Chemical Reactions: Engaging DIY Activities for High School Students and Homeschoolers!
Introduction:
Welcome to our DIY Activity Idea Blog for High School Teachers, Students & Homeschooling Parents! In this post, we will explore hands-on activities that allow participants to learn and demonstrate different types of chemical reactions. These engaging experiments will not only enhance understanding but also foster curiosity and excitement about the world of chemistry. Let's dive in!
Activity 1: Exothermic Chemical Reaction
Materials Required:
- NaOH pellets,
- water,
- safety goggles,
- gloves, and a beaker.
Procedure:
Participants should wear safety goggles and gloves for protection. In a beaker, mix NaOH pellets with water and observe the reaction.
Discuss the release of heat energy and the characteristics of an exothermic reaction. Encourage students to feel the warmth generated during the process.
Activity 2: Endothermic Chemical Reaction
Materials Required:
- Baking soda
- citric acid
- water
- safety goggles
- gloves
- container.
Procedure:
In a container, mix baking soda and citric acid. Add water and observe the reaction.
Discuss how the reaction absorbs heat from its surroundings, making it endothermic. Participants can experience the cooling effect produced during this process.
Activity 3: Displacement Chemical Reactions
Materials Required
- Copper sulphate, Iron Sulphate, Zinc Sulphate
- Copper, Iron, Zinc pellets
- safety goggles, gloves, and test tubes.
Procedure:
Place small amounts of copper sulphate, ferrous sulphate, and zinc sulphate in separate test tubes. Add copper, iron, and zinc pellets to each test tube, respectively.
Observe the reactions and discuss how a lesser reactive element is replaced by a higher reactive element in a compound.
Activity 4: Redox (Reduction Oxidation) Chemical Reactions - Blue Bottle Reaction
Materials Required:
- Sodium Hydroxide, Glucose, Water, Methylene Blue indicator,
- safety goggles, gloves and a container.
Procedure:
Mix sodium hydroxide, glucose, water, and methylene blue indicator in a container. Observe the reaction and the color changes that occur.
Explain the concept of redox reactions and how electrons are transferred during this process.
