 * Measuring Volume Using Displacement **

The second phase of this displacement lab gives fourth grade students an opportunity to problem-solve when lab results become unpredictable. Students will need to think backward to understand fractions of milliliters.

 * Lesson Plan: Worksheet: Assessment:**

Once students have a basic understanding of evaporation, this lab will allow them a chance to investigate further by designing their own test. Students will need to isolate and control variables to design a fair test.
 * Benchmark Papers:**

For example, students may want to test:
 * how air currents blown over the surface of water affect the rate of evaporation
 * how varying liquids (diet soda v. regular, amonia based v. water, carbonated water v. tap water, etc) affects the rate of evaporation
 * how different shaped containers affect the rate of evaporation
