Sponge Tub

The Field Operations Team, South Bay

San Mateo and Santa Clara Counties

The Sponge Tub is an activity where ice is dumped into a bin filled with water. The melting ice mimics sea level rise. Sponges are introduced as wetlands which help soak up the water and bring the water levels down. This activity helps people of all ages visualize sea level rise and the baylands as a sponge.

Your TurnBuy an inexpensive tub, ice, and different edge materials (i.e. different household items like paper, sponges, cardboard, etc). Fill the tub with water and design your own edge of the shoreline with the household items. Add ice into the tub and notice if your edge absorbs the rising waters.
