Instruct participants to hold their arms straight out in front of them and to make a square finger frame with their thumbs and forefingers. They line up an interesting object and focus on it, then list other things they can see through the frame. Ask students to look at the ground, foliage, animals the sky etc.
Ask students to share their memory by showing their finger frame so each partner can see the same area.
This can be a good activity to give to groups on long walks or to do when walking between points of interest.
At the end of the walk, you can ask students to share their memory with the whole group and to share it with their family at home that night.
