Notes

Mainly sunny with some hazy clouds and windy. Water choppy. Dragonflies and some black flying bugs see. I had a super helper today doing our testing....a young girl from Smiths Falls area who was on beach with her family. She attends an eco-class there and was very keen to learn about what our tests were about . She had a good eye for colour matching too. Gave her some badges now that she's a Water Ranger . 😀 Encouraged her and Mom to tell her teacher about this and maybe get a kit for their students to use .
