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.

Have you ever heard someone say, "that plant is thirsty" or "give that plant a drink of water"? We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? In this science project, you will use colored water and carnations to figure out where the water goes. Read more

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

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

Juice boxes are so convenient—just poke the straw in and sip away! But have you ever noticed that some juice boxes don't seem to have much juice, even when they have a lot of packaging? It might surprise you how much thought goes into the design and manufacturing of a juice box. Each manufacturer has carefully calculated how big each side should be to hold a certain amount of juice inside. In this science project, you will find out how different brands of juice measure up.

Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape. Read more

When you picture video games, you probably picture realistic figures, a lot of color, and a lot of detail, right? Those descriptions do not really describe video games from the early 1980's. So why do video games today look better than video games from the 80's? One major change between then and now is the number of pixels, or dots on the screen, used to represent video game objects. When Nintendo® first introduced the Super Mario Bros game for the Nintendo Entertainment System (NES) in… Read more

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
