Free science curriculum for homeschool families exists for all ages and grade levels. Although each of these curricula are free to download, you should be prepared to spend a little on printing worksheets and gathering the supplies needed for each of the hands on activities. All of these are complete programs, providing enough instruction for at least a full years worth of learning.
Creating your own curriculum is also possible. You may choose to simply follow the guidelines offered by the Core Knowledge Foundation or choose your own course of study, then teach your child using library books or children's encyclopedias. You'll find a wide variety of relevant experiment ideas at websites such as Science Buddies.org.

Use the Library
You can teach science simply by using library books. In fact, it may be the best source of free science curriculum for homeschool. You can decide on a list of weekly topics for the school year, then borrow books as needed according to your schedule. Some parents parents choose to allow their children to guide learning, and read science books on any topic of interest. I recommend the Lets Read and Find Out series by Harper Collins, the Magic School Bus series by Scholastic, Kingfisher and Usborne encyclopedias and the Science for Every Kid series by Janice VanCleave. In addition to these suggestions, most libraries offer hundreds of suitable titles.
When you use library books to teach science, it is helpful to have your child keep a science journal where he can write what he has learned in the books he reads, as well as details and photographs of each experiment. You may also want to choose vocabulary words or facts from each book for your child to memorize.
As you can see by the above list, there are several options for free science curriculum for homeschool students, regardless of age or grade level. If none of the free curricula suit your needs, you may choose to decide which science topics your would like your child to study, then spend a few hours each week studying library books and doing experiments.
