Shopping List for Unit 20

Here is the list of materials for doing ALL the experiments in the entire Unit 20 section on atmosphere and geology.

How many of these items do you already have? We’ve tried to keep it simple for you by making the majority of the items things most people have within reach (both physically and budget-wise), so you can pick and choose the experiments that fit with what you’d like to do. Since the lessons for Earth Science require very different materials, we’ve keep them in two separate itemized lists for you.

Here’s how to use this shopping list: First, look over the list and circle the items you already have on hand. Browse the experiments and note which ones use the materials you already have. Those are the experiments you can start with. After working through the experiments, your child might want to expand and do more activities. Make a note of the materials and put them on your next shopping trip OR order them online using the links provided below.

    A lot of these items you probably already have around the house. For the geology unit, don’t feel like you have to go out and purchase a bunch of rocks! The ones I use in the videos are from GeoIndustries and there’s order links if you really want those particular ones. I would recommend the “Geology Field Trip bag” and the Washington Student Pack, both are under $10. Does that help?

    where do we find the supply kits to purchase for each of these lessons? Are they more affordable than filling my Amazon cart?? LOL

  3. Heather Sukut Sukut says:

    Is there a lesson on the layers of earth- core, mantle, etc?
