Objective: Children will investigate properties of water droplets on surfaces.‹ Return to Theme
Raindrops are liquid water. Water in its liquid state will flow. Gravity causes water to flow downward. Water can be made to move upward if enough force is applied. Water is attracted to and clings to itself; this is called cohesion. As drops of water get closer together, they will merge to form a larger drop. Larger water drops resist being divided.
Water reacts differently on different surfaces. Water is attracted to some materials due to their composition. The attraction of water molecules to other materials is called adhesion. When water sticks to something porous like a paper towel, the molecules are pulled apart because they are being absorbed.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
While we believe that the books and resources recommended may be of value to you, keep in mind that these are suggestions only and you must do your own due diligence to determine whether the materials are appropriate and suitable for your use.

There are currently no Common Core Standards for pre-k, but these lessons are aligned as closely as possible to capture the requirements and meet the goals of Common Core Standards. However, these lessons were neither reviewed or approved by the National Governors Association Center for Best Practices or the Council of Chief State School Officers, which together are the owners and developers of the Common Core State Standards.
