I have researched my experiment and when I have finished choosing my project I search the ingredients I needed for my experiment.
Where can I get clean sands? May this can happen? I research more than 10 days.
29 January 2020 - 5 February 2020
I try to Guardian or Fair Prize to purchase my ingredients. It was hard to find clean sand and clean rock. So I used the sand in the sandpit in my school. Also, I used the rocks that is in the playground.
