1. Find something you can comfortably sit on outside, a folding chair or a cushion and blanket. If you have a magnifying glass or binoculars please take them with you.
2. Go find a flower and watch it closely, the longer the better. If you have one, you could use a magnifying glass. Try to notice everything you can about the flower:
colours
textures
shapes
insects
3. Try to find a robin. They like being close to people because they're used to picking up insects disturbed by animals walking through their forest. They tend to be the first and last birds to sing in the day, and the only birds to sing through the Winter. Once you find one singing, you'll be able to go back to the same place regularly. Make yourself comfortable - you'll need some warm clothes if it's early in the morning or late in the evening. Imagine your robin is singing just for you.
If you're unable to go to a patch of forest then click on this youtube link to hear the sound of a robin singing.
Watch the movements of the robin's throat, notice the pauses, marvel and forget about time.
