I recommend a lot of books and other materials on this site. Some of these are affiliate links, meaning I earn a small commission if you purchase something through the link. However, I absolutely do not endorse products that my children and I have not personally used and enjoyed. All recommendations and related affiliate links that you see on this blog are supplies that I use, trust, and love and have no qualms about endorsing! Thanks for supporting The Science Kiddo and allowing me to continue supporting you in your journey.
