Science Buddies' kindergarten science projects are the perfect way for kindergarten students to have fun exploring science, technology, engineering, and math (STEM). Our kindergarten projects are written and tested by scientists and are specifically created for use by students in kindergarten. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, kindergarten students can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Let us help you find a science project that fits your interests, with our Topic Selection Wizard.

Science Fair Project Idea
Do you like playing with play dough; or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this project, you will use play dough that conducts electricity, which will allow you to connect lights to your sculptures! This project is the first in a three-part series on play dough circuits, which can all be done with the same materials. We recommend doing the projects in order. Read more

Have you ever seen a magician float an object in the air? If so, you might think that levitation (making things float) is just a magic trick, but the truth is you can use an invisible physical force to levitate a magnet! Try this science project to find out how. Read more

If you leave an ice cube out on the kitchen counter and come back to check on it in awhile, what do you find? A puddle! The same thing happens to ice in nature—if the temperature gets warm enough, it melts. In this ocean science project, you will find out what happens to sea levels if the ice at the North Pole melts, or if the ice at the South Pole melts. It is an important question for the millions of people who enjoy living along the coasts of the world. Read more

Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy? Read more
Science Fair Project Idea
Electricity powers many of the devices we use every day, from lights to video games and computers. Engineers have to use certain materials to make electrical devices work. In this experiment, you will find out which materials let electricity flow through them (conductors) and which ones prevent electricity from flowing through them (insulators). Read more
Science Fair Project Idea
Have you ever stood close to a fossilized T. rex skull and counted its razor-sharp teeth? Or, have you seen a fossilized stegosaurus skeleton and thought about how it defended itself with tail spikes and armored plates? A trip to a natural history museum lets you imagine what dinosaurs looked like and wonder what life with them on Earth was like. Fossils give us information about animals and plants that lived long ago. Certain places around the world contain more fossils than others. Why?… Read more
Science Fair Project Idea
Saturn is a unique planet because of the many beautiful rings surrounding it. How are all of those rings made? Why is each ring unique? Read more

Have you ever heard the expression, "You can't judge a book by its cover"? What do you think that means? That a book with a very plain cover might have a very exciting and interesting story inside? Well, in this geology science project, you'll see if the same expression holds true for a rock, but not just any old rock, a special type of rock called a geode, which looks rather plain and ordinary on the outside, but inside can hold crystals and beautiful colors! You'll discover if the texture or… Read more

Doctors use many complicated tools to check the health of patients. But you can make some medical tools at home—like a stethoscope! A doctor uses a stethoscope to listen to a patient's heart. In this science project, you will make three of your own homemade stethoscopes and figure out which stethoscope design works best and why. Read more
Science Fair Project Idea
A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games, and build sand castles. But have you ever thought about how all of that sand got there and wondered why the shoreline weaves in and out of the ocean? In this science project, you will investigate how ocean waves build beaches by making a model of the beach and shoreline. All you need is a tiny surfer and a beach volleyball court for your model, and you can imagine that you are in… Read more
