 * Sink and Float**
 * TEKS**

The students will investigate the concept of sink or float by investigating different objects in water to test whether they sink or float by collecting and recording data on a graph. Students will connect their findings to other things that sink and float in our world and how those things affect our environment.
 * Objective**

Connect real life things and situations dealing with floating and sinking. For example: Why do people float in the Dead Sea? __Environmental Connections:__ Students discuss visits to the beach when they have noticed marine debris and trash floating on the beach. They can give examples of how they have participated in or heard of organized beach clean-ups on beaches. This lesson will help them understand what marine debris is, how it is generated, and how it came to be on the beach, which harms animals.
