"What I like about the book is the activities are sometimes science, sometimes art. They involve observation, collection of leaves and rocks, etc. There are year round activities too - things for winter, summer, etc. We recently did an experiment to see what floats and what doesn't. We went for a long walk, collected pine cones, sticks, leaves, flowers, rocks, and brought them back to test what floats and what doesn't, and then read the book's explanation of why. If you have time to do this with your kids on the weekend, I think it's fun, and I would recommend it." -- Customer Review
