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.

Science Fair Project Idea
Have you ever had fun making different figures or colorful creations using some Play-Doh? You can squish and stretch a single piece of Play-Doh® to make all sorts of shapes. How does changing the shape of a piece of Play-Doh affect its volume? In this science project, you will find out by testing how changing a piece of dough's shape affects its dimensions (length, width, and height), and how these changes are related to the dough's volume.

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

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. Which property (or aspect) will change the most: the length of an edge, the surface area, or the volume?

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
