Attention - Shipping

The transition of our inventory to a new warehouse is taking longer than we anticipated. As a result, we are experiencing fulfillment delays and order(s) are taking longer to ship out. We are working hard to get the stock moved to our new facility as quickly as possible so that we are better equipped to meet your needs. We apologize for any inconvenience this may cause you.


Hundreds of thousands of boats and ships and the materials and supplies on them have sunk to watery graves since humans first sailed the oceans. Even today, it is common practice for humans to throw their waste into the seas. In the past, much of that material would degrade and/or decompose in the ocean waters. The composition of waste, however, has changed from natural, biodegradable materials to synthetic materials that resist decay. In this Activity, you will observe the breakdown of various materials in water and in sand. Readings
