Product Description

This demonstration can be used to show that ocean currents move in the same direction as global winds except water can be blocked by land masses such as continents. The use of plant-based biodegradable straws for this activity led to great discussion about plastics, garbage in the oceans (Great Pacific garbage patch), and what this means for sea life. Our groups of four had also blown into their straws to get an idea of how gyres can form done as a demonstration keeping in mind that there's no land in the center of gyres. Materials were 1 square plastic box (the size of a shoe box) per group of four. Some cool rocks to put in the center (representing a land mass). Filled the box so the rocks were about half way covered with water. Paper holes from the classroom hole puncher were used to demonstrate surface ocean currents which worked really well because they were easily blown by the straw but some got soaked and sank (representing the deep ocean) and were not affected by the surface wind (created by blowing through the straw)...just like the ocean. Simple, effective, and they had fun! KEY INCLUDED.
