When I began setting up this station in my classroom 5 years ago, I actually started by posting a project on Donorschoose to get hands-on science activities (for more info on Donorschoose, read this post)!
After brainstorming my topics (1 for each month), I went shopping online on Nasco, Lakeshore, and Kaplan for any hands-on activities related to my topics. I also asked for general science materials like scales, measuring tapes, calculators, and general science file folder activities to be used year-round. Then, as I waited for my projects to be funded (which they were!), I started creating my own worksheets and activities.
I definitely recommend using Donorschoose to supplement your science units. Unfortunately, since I wrote these projects about 5 years ago, a lot of the materials are no longer available. Here are some of the items I found still available:
Inflatable Solar System (for your solar system unit). We hang this in my classroom every year and the kids love it!
Tornado Tube (for your weather unit)
Weather Tracker (for your weather unit)
Root Vue Farm (for your plants unit)
Anatomy Apron (for your body part unit)
A Newer version of a Food Group Pocket chart (for your Food Group Unit)
Sink or Float Kit

The write-up part of this grants is very short and to the point. I didn't want to lose my readers' interest by making it too long or detailed. See what I wrote below:
