[Houa's Blog] what happen

The result of the experiment change because there was only clay that is in the 50 ml and there was no humus or sand on the 50 ml then my group held the bucket and went over to the sink and poured some of the runoff water into the 50 ml and the next day at Investigate 2 we check them again and we compared them to the first Investigate and the second Investigate.
