What Makes Water Special?
Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Discovering Cohesion, Adhesion and Surface Tension
Students investigate cohesion, adhesion and surface tension through observations and lab experiments. In this cohesion, adhesion and surface tension lesson plan, students rotate to 5 stations around the room and experiment at each...

Physical Properties of Matter
Five fabulous procedures introduce physics or chemistry classes to special properties of matter. They discover adhesion and cohesion, solubility, melting and boiling points, and viscosity through hands-on experiences. Tests are...

Stick To It!
High schoolers compare different types of pressure sensitive adhesive tapes. They fevelop and carry out tests for variables affecting the force needed to peel tape off a surface. Students analyze the time needed to peel the tape with...

Surface Tension: Liquids Stick Together
Use science to help you walk on water! Young scientists explore the properties of liquids including cohesion, adhesion, and surface tension. They use graphs to compare different liquids and make predictions about their molecular attraction.

Propel a Toy Boat with Chemicals
A simple cardboard or plastic boat is propelled across the surface of water when the surface tension is disrupted by adding detergent. Once youngsters see this in action, explain about the properties of water that make it possilbe:...

Does Size Matter?
Young scholars explore the surface area to volume ratio in cellular respiration. While participating in an interactive lab experiment, they examine proportional surface area and discuss nanotechnology. Students observe the...
