Project Idea
thumbnail If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Project Idea
thumbnail Everybody knows that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You've probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? Here's a project that gives you a peek into the fascinating science of exercise physiology. Read more

Project Idea
thumbnail Chemicals from Earth's atmosphere are making their way down to the planet! Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems? Read more

Project Idea
Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. Read more

Project Idea
thumbnail Alka-Seltzer® tablets fizz furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. Can you make Alka-Seltzer fizz faster or slower by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more

Project Idea
thumbnail On a hot summer day, don't you just love opening a can of your favorite soda pop and taking a deep drink? The bubbles in the soda tickle your tongue's taste buds and propel the ingredients to your palate and nose so that you get a kick of flavor. But how do the bubbles, fizz, and taste get into the water? In this cooking and food science project, you will work with baking soda, citric acid, and sugar to create a your own soda pop. Once you develop your recipe, try it out on your friends and… Read more

Project Idea
thumbnail This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer® tablets are plopped into water. You'll track the volume of carbon dioxide gas produced at regular intervals after the reaction begins. How does changing the temperature of the water affect the production of gas? Read more

Project Idea
thumbnail Some chemical reactions occur explosively fast, others may occur almost imperceptibly s-l-o-w-l-y. This project explores what effect the particle size of the reactants has on the speed of a chemical reaction: production of carbon dioxide gas by an Alka-Seltzer® tablet. Read more

Material Availability Readily available
Cost Very Low (under $20)
Safety Adult supervision recommended when working with hot water solutions
Project Idea
thumbnail 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
