Children are naturally curious about the world around them. They want to understand why things are the way they are and how things work!

However, science can be a challenging subject to teach your child due to its scope and complexity. Drawing from our experiences and research, we have designed a curriculum that gives your child a foundation in science and its many disciplines. There is no prep work for you as the parent and no grading. Simply enjoy the videos with your child and help your child complete the simple activities that use materials you already have around the house. Each course includes 180 video lessons, as well as printable activities and other supplementary materials.

What will your child learn in 1st Grade Science: students will study how animals and plants survive and interact, will get a primer on chemistry and physics, will explore the Solar System, will discover the important geologic and atmospheric features of planet Earth, and will learn about how our bodies work and how we take care of them!

Lindsey and George Schweitzer are the course creators for 1st, 2nd, and 3rd Graden Science. Lindsey has over a decade of teaching experience in both public and private schools and is the creator of thishomeschool.com, a website of educational resources. George has over fifteen years of experience in academic and clinical medical research and statistical analysis. Together, they homeschool their own children and have created these science courses to help you and your child enjoy the freedom and fun of homeschool!
