How to Choose a Science Curriculum

When choosing a science curriculum for your child, there are a few things to consider.

First, make sure you consider the homeschool laws in your area. What topics or subjects are required for your child to learn? Make sure the curriculum that you choose covers this material.

Secondly, do you need a curriculum that is flexible or a curriculum that follows a set schedule? Do you want free science curriculum that can be done in a few hours per day or are you looking for a curriculum that offers lessons for five days a week?

It’s also important to consider science experiments when choosing a homeschool science curriculum. Are you looking for a curriculum that includes lots of hands on activities for your child to do? Or would you prefer for your child to learn by reading a textbook?

Finally, it is important to consider the worldview of the curriculum publishers. If one of your reasons for homeschooling is to teach your child with a Biblical worldview, it is important to choose a science curriculum that supports your beliefs.
