Nursery garden

Hello all,I  would like some input. Currently in a group to help the nursery become more wildlife friendly, and encourage kids to become more involved with fruit and veg. They’ve asked us for ideas and I’m not very creative and this seems to be all I can come up with. Does anyone have any input to how we can help them. I’ve searched past week on here for tips on different sites and places to help so it’s more on design for maximum impact. The green areas are wildflowers I have added a tunnel of raspberries with a tipi of peas or sunflowers, Raised beds and there’s already a sheltered bike like storage place which might be good as a sort of greenhouse, potting area. There is already a mud kitchen, slide etc on the other side of the garden, they also want this more natural looking as it’s wooden but on soft flooring with short fence around it so no soil here, so at a loss on how to implement this. I would appreciate as much help as possible, I’ve been stuck down a Pinterest hole for two days, and prefer real people ideas. There is two parents (including me) and 4 staff members. This is for 3-5 year garden, there is two other concrete style gardens for younger children, I have a few ideas for there regarding sensory style plants in raised planters. This is my idea so far for this part of the garden. And this is its current look
