Successful kindergarten science projects appeal to the kids' natural curiosity and focus on their interest in their personal environments. For example, using plastic spoons or shovels, kids dig into the ground and observe the different kinds of soils, rocks, plants and animals found there. Another outside investigation involves visiting a tree several times during the year to identify changes and seek evidence of other living organisms.
Another science project encourages kids to explore ice. After putting a piece of ice on a plate, kids guess what is going to happen and then explain their predictions. They also experiment by putting the ice cube in different places to see if location impacts melting.
Kindergarteners might also explore falling objects. First, kids predict what they think will happen when they drop certain objects from the same height. They experiment with a ball, feather, sheet of paper and paper wad, and compare the results while noting any incorrect predictions.
Young children are very interested in themselves, so science projects about the human body generate a lot of interest. Kids observe specific physical characteristics about themselves and others, comparing hair color and texture, eye and skin color. Similarities and differences are noted.
An engaging, but messy, kindergarten science project lets kids explore how bubbles work. When offered a variety of wands, they predict which will make the biggest bubbles and then check their predictions. Children also try making their own wands from materials such as straws, strings and rolled-and-taped pieces of paper to see which materials work best.
