Fiona here from the SLJ. WOW - I am so impressed by the way you have designed your dam using natural materials and used the sink to test your structure. I really like the way you report in your blog that you tested water flow and the water didn't run through. This is an important finding - ka pai!
Did you put the big stones at the bottom and the small stones on top, so they didn't fall down the plug? You have done a great job.
I'm going to take a look at your 'Step it Up' post now for this activity!
Kia ora Molly,
