Physical Science Explored Lab & Activity Supplies

 

This post contains affiliate links.

Below you’ll find options for where to purchase the few specialty items required, along with a complete list of lab supplies needed for each lesson in Physical Science Explored.

Please note: If your student is taking the  Level C version of this class, there are a few additional supplies required which are listed at the bottom of the page.

Lab Supplies on a Budget

Many of the labs and activities in this course require easy-to-find items you probably have around the house or can find inexpensively at a local store. 

If you aren’t able to fit the specialty supplies into your budget, we’ve included demonstration videos for most the labs in this course. This will allow your student to still observe the lab and answer the lab questions, but will help keep the class more affordable. 

Where to Buy Supplies?

 

1. Purchase the Physical Science Explored Custom Kits 

Cornerstone Educational Supplies has created a lab kit with the specialty supplies for those who would like to complete all of the labs. Families may pick and choose which labs to complete. However, if you would like to do all or most of the labs, this is the most economical way to purchase the specialty lab supplies.

2. Purchase supplies a la carte:

Most families won’t complete all of the labs. For those who will be picking and choosing which labs or want to purchase just a few supplies at a time, use the links in the list below to purchase items a la carte from Home Science Tools.
