About This Chapter
Chemistry Demonstrations- Chapter Summary and Learning Objectives
In this chapter, you will learn some experiments and demonstrations that can be used to help increase knowledge on chemistry. Since chemistry can be challenging to understand, using these experiments can make chemistry fun and engaging. Two of the labs presented here will go over how Diet Coke reacts to Mentos, and how Pop Rocks react to soda. Additionally, the types of experiments found in this chapter are the following:
- Burning candles in water
- Lemon batteries
- Turning milk into plastic
- Zinc flame
1. Diet Coke and Mentos Experiment
In this experiment, we'll be studying nucleation of gases under pressure. To do this, we're going to combine Mentos, a small minty candy, with a bottle of Diet Coke. This experiment can get messy, so make sure you have some outdoor space to do it.
2. Burning Candle in Water Experiment
In this chemistry demonstration, you'll see the affects of temperature on air pressure. During this experiment, we'll be able to see how burning a candle affects the air temperature, and thus pressure inside a glass container.
3. Lemon Battery Experiment for Kids
In this chemistry demonstration, you'll be making your own battery! Instead of using the chemicals that come inside the ones from the store, you'll be using the awesome power of fruit, a lemon. By doing this experiment, you'll learn about what chemicals help batteries make electricity.
4. How to Turn Milk into Plastic - Science Experiment
In this demonstration, we'll be learning about the structure of polymers. We'll also get to see how acid-base reactions affect the organization of molecules. By the end of the demonstration, you'll understand how chemical reactions can impact the physical properties of substances.
5. Pop Rocks and Soda Experiment
In this chemistry demonstration, we'll explore how Pop Rocks work and how the unique makeup of this candy can be combined with soda to blow up a balloon.
6. Zinc Flame Test
In this lab, we'll be learning about flame tests. After doing this lab, you'll be able to explain how the flame test works and identify different compounds based on flame test results.
