Elementary Science Projects

Here is a collection of elementary science projects. These experiments were selected for the relatively short time it takes to complete one, for scientific value, and for fun value. If you do not see an experiment here that you would like to do, please try one of the other grade categories - they may have what you are looking for. 

Fun Science

Popcorn Science Project

Like popcorn? Ever wonder why it pops? Here is a popcorn science project that will show you why - one of our many great elementary science projects.

Easy Science Experiment: Blue Rose

Looking for something fun and really easy? Check out this easy science experiment. 


  • Electro-magnets! Get a length of small gauge wire, an iron nail, and a 9 volt battery to have the makings of a cool electro-magnet experiment. You can go in many directions with this, like magnet strength: does the size of the battery matter? How about the number of times you wrap the iron nail with the wire? Or magnetic poles: if you make two electro-magnets, do they attract or repel each other? Depending one which end is facing which? A great elementary science project.

  • Fluorescent Lights Ever wonder why schools and office buildings often use florescent lights instead of the bulb (incandescent) lights? This experiment should show how florescent lights use less energy for the same amount of light output as do bulb lights.

  • Airplane Wings Ever wonder how airplanes fly? For most planes, itís all about the wings. In this experiment you should show how wings create lift for the airplane because of their shape. You could show how differing shapes create different amounts of lift.

  • Water Distillation This elementary science project would show how to take water thatís contaminated with salt or food coloring, distill it, and get pure water out. A thorough explanation would go into the details of what happens to the water molecules when they heat up, but it is not necessary for a good experiment.


  • Salt Water and the Freezing Point Show how salinity (the amount of salt in water) can affect how cold water has to be before freezing. Explain some of the practical implications of this ñ like why do they salt the roads in cities where it snows?

  • Where does Glass come from? We use glass everywhere ñ windows, windshields, drinking containers ñ but where does it come from? This elementary science project would show how glass is made from sand (!) and would have some explanation for why sand itself is opaque (you can not see through it) and why glass is transparent (you can see through it.)

  • Oil in Everyday Life Did you know that besides being used for gasoline, oil is used in the making of plastics? This experiment would reveal why oil is so important for more than just fuel and show the various products we use everyday that were made from petroleum (oil), or used petroleum in their manufacturing process.

  • No Fire Without Air (Make SURE you have adult supervision for this one!) Did you know that if you take a piece of paper, place it in a container that has no air, and then apply a blow torch to it ñ that it will eventually glow red hot but not catch fire? You can do a simpler version of this experiment with a small candle and glass bowl. Figure out why this happens and you have the makings of an excellent experiment. This one is a bit advanced for an elementary science project, but with adult supervision it can be rewarding.


  • Radiators and Air Movement If you live in a mature house or have been in an older office building, you have probably seen those odd looking heaters next to the window called radiators. Did you know that they cause the air to move in the room that they are in? How do you suppose they do that without any fans? The answer lies in rising and falling air due to temperature changes. This is a great experiment that leads into weather science (Meteorology.)


  • Plants and Sunlight Have you noticed that plants in your house tend to grow in the direction of the sun coming into the room? How do these plants know where the light is coming from without eyes? This experiment deals with tropism the reason behind this behavior. Another great elementary science project.
