Tomorrow we will go over the background research you will need to do an experiment with soil pH.
For an upcoming experiment, you will need to collect a sample of soil and small rocks from a local source. A nearby park, your backyard or a neighbor’s flower bed (ask first).
You won’t need them for tomorrow, but in case you need some time to go get them the instructions are in purple below.
For our pH experiment you will need some soil and some rocks from a local source. Since you will be using these for another experiment next week be sure to get enough. Around half a cup of each should be plenty.
Take a spoon and 2 zip top baggies with you. Find a place you can collect soil or rocks from. Your backyard, the local park or a potted house plant are all good options. Be respectful, try not to disturb any plants in your collecting.
Spoon about half a cup of soil or rocks into your bag. Seal the bags and take them home with you. We will use this in our experiment at the end of the week.
