Kindergarten Science Projects (55 results)

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.

Electric Play Dough Project 1: Make Your Play Dough Light Up & Buzz!
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

Material Availability Kit available for purchase from our partner Home Science Tools. See Materials tab for details.
Cost Low ($20 - $50)
Safety Never connect the battery pack's terminals directly to each other; this is called a short circuit and can make the batteries and wires get very hot. Do not connect the LEDs directly to the battery pack without using play dough; this will burn out the LEDs.

Racing Bristlebots: On Your Mark. Get Set. Go!
Science Fair Project Idea
Have you ever wanted to build your very own robot from scratch? Bristlebots are a cheap, easy, and fun-to-build robot made from the head of a toothbrush, a battery, and a small motor. Once completed, they buzz along the top of a table like bugs. How can you make a bristlebot go faster? In this project, you will build bristlebots from two different types of toothbrushes, and race them against each other to find out. Read more

Which Materials are the Best Conductors?
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

A Magnifying Discovery
Science Fair Project Idea
Have you ever looked through a magnifying lens? Why do things look bigger when you look at them through the magnifying lens? Even though the object appears to get larger, it really stays the same size. Each lens has its own unique power of magnification, which can be measured with a ruler. How powerful is your lens?

Bones and Calcium
Science Fair Project Idea
Why is your grandmother always wondering if you are drinking enough milk? Our bones are made out of calcium, a mineral found in milk, and drinking milk can lead to strong healthy bones. What about other animals? What are their bones made of? What kind of bones do they have? Are there animals without bones? Are endoskeletons and exoskeletons made out of the same materials? Read more

Bubble-ology
Science Fair Project Idea
Making your own bubble solution is fun, but sometimes the bubbles don't seem to work as well as the solutions you buy in the store. In this experiment you can test if adding corn syrup or glycerin to your bubble solution will make it just as good as the stuff you can buy. This experiment will have you blowing bubbles! Read more

Bug Vacuums: Sucking up Biodiversity
Science Fair Project Idea
Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more
