Experiment with Acids and Bases Science Projects (15 results)

Experiment with acid substances that donate hydrogen ions in water and base substances that accept hydrogen ions in water. Make your own pH paper to find out how acidic solutions are. Or experiment with acidic reactions--even in products you make, like shampoo or bath bombs.

Bath Bomb Science
Science Fair Project Idea
Scientific Method
Have you ever had a refreshing bath using a bath bomb? A bath bomb is several ingredients mixed and molded into a shape, which becomes fizzy when it touches the water. It can be quite a relaxing experience, especially if your bath bomb has a nice fragrance or includes some bath salts. The fizz is the result of a chemical reaction taking place between different ingredients within the bath bomb. In this science project, you will get to make your own homemade bath bombs and explore how changing… Read more
Baking Soda and Vinegar Rockets
Science Fair Project Idea
Scientific Method
Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more
Cabbage Chemistry
Science Fair Project Idea
Scientific Method
This experiment is for all the kids out there who love boiled cabbage! You say you do not like cabbage? Well maybe you will like this amazing color-changing liquid you can make with cabbage. Which solutions around your house can make the cabbage juice change color? Find out while you learn about acids and bases and how to test for them. Read more
Measuring the Amount of Acid in Vinegar by Titration with an Indicator Solution
Science Fair Project Idea
Scientific Method
Have you ever wondered why some foods taste really sour? Vinegar is one example that you might know from salad dressings or pickles. They taste pretty sour, right? There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. Do you think all the different vinegars contain the same amount of acetic acid? Are there some that are more sour than others? How… Read more
Rusting Out: How Acids Affect the Rate of Corrosion
Science Fair Project Idea
Scientific Method
Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more
The Chemistry of Clean: Make Your Own Soap to Study Soap Synthesis
Science Fair Project Idea
Scientific Method
Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more
Make Your Own pH Paper
Science Fair Project Idea
Scientific Method
This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions. Read more
Make Your Own Shampoo and Test How It Performs!
Science Fair Project Idea
Scientific Method
Do you love it when your hair is nice and fresh? The key to keeping your hair nice and clean is to use a good shampoo. But with so many different products in the store, how do you know which one works best for you? In this science project, you will put a variety of shampoos to the test, including your own homemade organic shampoo recipes. Do you think these will perform better than a store-bought product? Read more
How Antacids Relieve Heartburn
Science Fair Project Idea
Scientific Method
Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more
From Dull to Dazzling: Using Pennies to Test How pH Affects Copper Corrosion
Science Fair Project Idea
Scientific Method
Pennies are bright and shiny when they are new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer. It turns out, however, that the same process that makes the pennies shiny has bad consequences when it comes to copper pipes: it… Read more
