About This Chapter
Chemistry Experiments - Chapter Summary and Learning Objectives
In order to make learning science fun and engaging, experiments can be used in class or at home. These labs will help different kinds of learners who benefit from the hands on approach and visual benefits that experiments can bring. Experiments that will be addressed in this chapter relate to the how Alka Seltzer reacts to different temperatures, or being in oil, water, or a balloon. You can also see how to create hot ice and discover what the fastest way to melt ice is. Topics found in these labs also include the following:
- Ice and salt
- Acid-base titration
- Iron in cereal
- Projectile motion
- Dry ice and soap
- Strong acid-strong base titration
- Redox titration
1. Alka Seltzer & Temperature Experiment
In this experiment, we're going to learn how temperature affects the speed of chemical reactions. To do this, we'll be using the over-the-counter medication Alka Seltzer and studying its reaction with water.
2. Alka Seltzer in Oil vs Water Experiment
In this experiment, we'll be learning how bases react with substances that are hydrophobic and hydrophilic. To do this, we'll attempt to blow up a balloon by reacting alka seltzer, a common base, with both oil and water.
3. Alka Seltzer Balloon Experiment
In this chemistry experiment, we're going to understand acid-base chemistry and the impact of temperature by using a common medical remedy, alka seltzer. Our goal is to answer the research question, ''How does temperature impact rate in an acid-base reaction?''
4. How to Make Hot Ice Experiment
In this lab, you'll learn about exothermic chemical reactions by making ''hot ice''. Through making a supersaturated solution, you'll be able to see crystals appear right before your eyes.
5. Ice and Salt Experiment
In this experiment, you'll learn about the colligative properties of water. To do this, we're going to test the melting rate of ice with and without salt.
6. Homemade Ice Cream in a Bag Science Experiment
In this chemistry experiment you will be lowering the freezing point of water by adding salt to ice. The purpose of this experiment is to use this process to make homemade ice cream in a bag.
7. Iron in Cereal Experiment
In this chemistry experiment, we're going to learn about the process of separating elements in a mixture using principles of magnetism. By the end of the experiment, you'll understand these concepts as well as have an answer to the research question: ''Which cereal contains the most iron?''
8. Salt Water Density Experiment
In this experiment, you'll be learning about how density causes objects to sink or float. By the end of this experiment, you'll be able to answer the research question: ''How does the salt concentration of water affect the ability of an object to float?''
9. Viscosity Experiment
In this experiment, you're going to learn about viscosity. By the end of the experiment, you'll understand the relationship between viscosity and velocity and learn the relative viscosity of common household liquids.
10. What Melts Ice Fastest? - Science Experiment
In this lesson, we'll be learning about the physical properties of water. After doing this experiment, you'll be able to explain why certain substances melt ice faster than others.
11. Acid-Base Titration Lab
In this lab you'll be studying reactions between acids and bases. By using a known amount of a base, you can find the original concentration of an acid in a reaction. After doing this you'll also understand some practical applications for titration experiments.
12. Weak Acid-Strong Base Titration Lab
In this chemistry experiment, we'll be looking at how acids and bases react. Specifically, we'll be titrating a weak acid with a strong base and observing changes in pH using a pH indicator to find the initial concentration of the acid.
13. Strong Acid-Strong Base Titration Lab
In this experiment learn how to titrate a strong acid with a strong base. By the end you should be able to apply it to other titration labs, as well as understand the importance of the equivalence point in titration.
14. Strong Acid-Weak Base Titration Lab
In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this experiment you'll understand more about chemical reactions between acids and bases and the process of titration.
15. Dry Ice and Soap Experiment
In this chemistry experiment, we'll be learning about phase changes by combining dry ice with water. By the end of the experiment, you'll be able to answer the question ''How can a phase change affect volume?''
16. How to Prepare a Supersaturated Solution
In this experiment, you'll learn about the conditions needed to create a supersaturated solution. By using sodium acetate, water and a heat source, you'll be able to study how temperature affects solubility.
17. How to Make Oobleck: Recipe & Lab
In this chemistry lab, we will be making oobleck, a unique substance that has properties of both a liquid and a solid. Learn the recipe for this gooey stuff and find out about a similar substance that exists in nature.
18. Redox Titration Lab
Identify the concentration of a common household chemical, hydrogen peroxide. Using a known concentration of potassium permanganate, you'll be able to perform a titration experiment to discover the unknown concentration of hydrogen peroxide.
