Fun science projects are the heart’s desire of every elementary and middle school student headed to the science fair. To most kids, a science project simply has to be fun. Frankly, most teachers share this view. From a teacher’s standpoint, it’s much better for a student if he or she is interested in the topic being studied.
Of course, a fun science project isn’t the final goal. The purpose of a science project is to teach the child about science. To do that, teachers and science fair administrators usually have strict guidelines about what a project or experiment must include. Experiments must usually follow the scientific method. Demonstrations must explain a scientific principle. All projects must include research and references.
But a science project is also supposed to whet a child’s appetite for science. A fun and interesting project will make a student want to learn even more about our fascinating world and the scientific laws that govern it. And a fun science project is a great way to do just that.
1. Show how yeast gives off gas. Put yeast in a bottle of warm water, top it a balloon, and watch the balloon fill up with gas. This project can be done as a demonstration in front of the class, or as an fun science experiment.
2. What can you do to speed up a chemical reaction? Plop Alka Seltzer into a cup of water and time it. Then crush the Alka Seltzer, and watch it fizz even faster after you put it into a cup of water. Still another time, reduce the amount of water, add Alka Selter, and see how fast it dissolves. This is a demonstration science project, and is terrific to wow classmates.
3. Explore the concept of density. Pour water, Karo syrup, rubbing alcohol, and vegetable oil into a tall container. Watch how they layer. Then drop in different items, like a penny, a cork, a Lego or a candle, and see where they float – or sink. The concept of density is advanced enough for middle schoolers, but can still be understood by kindergartners.
4. Show how a chicken egg is a cell with a selectively permeable membrane. Soak a raw egg in vinegar for a weekend. The shell will come off. Then put the egg into dark syrup and watch what happens! This is another fun science project that can be done as an investigation or a demonstration.
5. Find out about static cling. Rub a sheet of plexiglass with a wool sock, then show how balloons and hair stick to it. Or, try make a ball of aluminum foil dance, as shown in this You-Tube video.
