Kerry has spent the last couple weeks building this giant balance that I saw on the internet and just had to have for this year's science projects. It's the perfect toy for our outdoor water and sand table.
Today the kids just experimented with the balance and weighed different amounts of sand.
Water was the next obvious choice to try out on the balance. A soaker hose has been wound through the shrubs, tree, and over the playhouse to create "rain" on hot summer days. The kids decided filling their measuring cups from the "rain" was ideal.
We'll continue to experiment and compare other things this week. We'll look at wet and dry sand, water and sand, water and river pebbles, sand and pebbles and whatever else the kids want to weigh.
