Last Spring, Onetime and I spent a fantastic sunny afternoon digging around in the backyard, trying to figure out what new plants we wanted to plant, and trying to decide if we wanted to dig up an old, unattractive bush to make way for a new veggie garden.
When we dug down under the bush we discovered some worms, an old piece of pottery and a mysterious underground wire. It got Onetime and me thinking about the components of soil and we decided to make a simple soil discovery bottle to find out more!
This discovery bottle sure ain’t pretty – but it’s cool! Read on to find out how we made it and what we learned from it!

Learning About Soil
We learned that soil is made up of many parts: organic material (decomposing plant and animals), sand, rocks and/or gravel, clay – and air and water of course.
In order to see these different components of the soil, you can make this simple soil discovery bottle with your kids.
- An empty water bottle (we used a VOSS water bottle)
Steps to Make a Soil Discovery Bottle
- Have your child dig up a couple handfuls of soil. Make sure to get some of the soil from the surface as well as some from underneath.
Tip: Use a spoon or a funnel to help get the soil into an empty water bottle.
- Fill the rest of the bottle with tap water, cap it off, and invite your child to shake the bottle for at least a minute!
- Allow the bottle to rest for the next 7 days while you observe what happens.
At first the water will be very murky with the plant material floating on the top.
Eventually, as things settle, the heavy rocks/gravel will sink to the bottom, then the sand will settle in a layer.
A thin layer of grey clay will appear at last, and the organic material will remain floating or will settle on the top.
The soil discovery bottle is a fun activity to do and to watch over the course of a week! If your child/children are extra interested, why not read them a book or two about soil?
