  1. Of course! You’ll find material lists that include order links when we need specific items. Otherwise, you can use the rocks you have in the backyard or in a personal collection if you’d like. The important thing is to learn about the testing techniques. We have several sets we recommend depending on which experiments you’d like to do. Here’s the 4th grade shopping list: https://www.sciencelearningspace2.com/standardcontent/docs/4th-earth-science-shoplist.pdf – do you see the link in the PDF for the kit?

    I’m trying to find the rocks and minerals to order. Not having much luck finding everything. It would be really nice to have a link to help with that. It’s really frustrating to find everything we need. I have no knowledge of rocks and minerals so it’s taking us a to long to get started. Thanks Amy
