THE WEEK 6 T1 UPDATE!

I decided last week that i will do an experiment on PH of household items. My aim is to find which household item that are used daily, is the most acidic! In my week 6 mind map below, i also included that to conduct this experiment, I would need to have PH solution and PH indicator. So, where am i going to get these? Right now, I am not sure... by week 7 update i would need to find out how to get these items. I should ask my teacher about my ideas on PH of household items, the next time i see her.
