Here is a list of the main scientific concepts students learn in pre-K and Kindergarten! These science concepts are organized into categories. To start, just click on any link. You can do these in any order at any pace that's right for you.

Physics A collection of introductory experiments that get kids excited and interested in the world of physics. Build roller coasters, play homemade musical instruments, slingshot fast catapults, fly gravity-defying airplanes, build a simple hovercraft, and play with the different states of matter as you explore, discover, and pique your curiosity and wonder as you step into science!
Earth Science This set of simple science experiments gets you introduced into what a real scientist does in the real world by building a weather station experiment and recording data in your first science journal (even if you can't write yet). You get to mark your data sheets to see how the weather changes from day to day and across the seasons.
Life Science Investigate the world of plants and animals by building an observational terrarium-aquarium where you can watch inhabitants in their natural environment. Learn how to identify physical characteristics such as stems, leaves, roots, arms, wings, legs and more as well as behavior differences and similarities.
