Science is a fascinating subject for many people. It is full of explosive experiments, incredible observations, and plentiful answers for everyday questions. Though the study of science can be complex and advanced, there are numerous opportunities for applicable, fun, and exciting projects and lessons and activities for kids. Homeschooling families can especially explore this often mind-blowing topic by incorporating it in their daily schedule with experiments, living books, virtual field trips, YouTube videos, and more.

However, as fun as projects can be, sometimes, science feels a bit costly. On-site field trips often require a large group admission, and science curricula may require additional purchases for kits and supplies to offer a complete study. Further, quality scientific tools like microscopes and telescopes do not come cheap. 

Even if you’re not a budget homeschooler, it is always helpful to find free resources to supplement your course of study. Thankfully, there are plenty of online science resources for homeschooling parents! Home education has come a long way from even a decade ago. With some research, you can find high-quality supplemental resources such as informational websites, games, worksheets, videos, tours, lessons, and interactive modules!

Helpful Supplemental Science Activities for Kids and for Homeschool Families

One of the advantages of science is that it can be as hands-on as you want. Science is a wonderful topic for all learning styles, as it can be applied effectively to each. While many people view science as an incredibly structured and complicated subject, it can be adapted to many situations and opportunities for flexible learning. For example, visual learners can utilize videos and experiments, tactile learners can succeed with project-based learning, auditory learners can listen to recordings, videos, and provide verbal reports.

Additionally, science adapts well to all homeschooling methods. Even if you are eclectic homeschoolers preferring a mixture of methods, you can incorporate science to fit! Whether your students learn from online lessons, textbooks, with a homeschool co-op class or even a community college course, science is one of the rare subjects that can meet every platform with success.
