Apologia Physical Science Module 4 Links: Water

I'm a homeschooling mom with a science degree. These awesome links will save you hours of research for your family!

Module 4: The Wonder of Water

Links and experiments about the amazing properties of water, to supplement Module 4 of Apologia's Exploring Creation with Physical Science. It is recommended as an 8th grade middle school course, but may also be used for 9th grade or younger advanced students.This curriculum is popular in Christian schools and homeschools to learn the science necessary for advanced education. I pray that by the end of the course, you will more deeply appreciate the wonder of God's creation!

Do you have your lab supplies?

You may need to order two test tubes!

Print the lab supply list above or at the Apologia website.
