The above AMSTI link was a general website. Here are the specific links for Math and Science. You can even select specific grade levels. The following are links for "Balancing & Weighing" Activities.
- Carolina Curriculum (This is where we get the T.E. for our kits.)
- Mrs. Roskow's Class
- Pinterest (Katherine Erikson)
- Math Worksheets for Kids

I hope that there are some resources here that you can use.
