Lab Supplies for Discover Physics

For any family looking for a robust physics course, hands-on lab assignments are a must—and this involves purchasing supplies.

While most students’ favorite part of physics is the labs, it’s not essential that students complete all of the labs. We recommend parents have students complete a minimum of the first two labs where we teach students about lab report writing plus 13 more labs (a total of 15 labs).

Where to Buy Supplies?

 1. Purchase the Discover Physics Custom Kit

Cornerstone Educational Supplies has created a lab kit for those who would like to complete all of the labs. We recommend students complete 15 of the 27 labs in the lab book that accompany this course. 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. 

Lab Supplies on a Budget

We understand the budget constraints of many homeschoolers — purchasing curriculum and supplies often for multiple children can be pricey!

We recommend your students plan to watch all of the lab videos and complete at least 15 labs for high school credit. Be sure to have your students complete labs that accompany lessons 1 and 2 where we teach students how to write lab reports.

So how can you make this work on a tight budget? One great way you can stay within your budget constraints is by completing the labs that only require easily obtainable lab supplies and supplies you can probably find around your house.
