measuring volume

I learned today how to measure volume so that we know how much gravel we need for our beautiful garden.

First we needed to measure the area of our garden - Length x Width. Then to convert it into volume we multiplied our area by the depth. Depth being how high we want the gravel to be.

Now you have the area Volume in cubic feet. To order gravel we converted our number into cubic yards. We divided our volume in cubic feet by 27.

We calculated that we need only one cubic yard of gravel for our first garden area!

Today our group is going to visit some more desert gardens to get some new ideas. Also, we will be digging some holes in front of the schoolyard to prepare to take soil samples.

Plant Research!

Last week we went to Desert Survivors Nursery in Tucson. We learned about different native plants. We got some ideas about what plants we want in our garden. Thanks Claire for showing us around! See http://www.desertsurvivors.org/ for more information.
