Surface tension is an excellent example of a force to teach to elementary students. It is amazing how many paper clips students can get to “float” using the force of surface tension! Your students might even have a fun competition to see who can float the most paper clips: two different techniques to “float” the paper clips are described here. All the science is explained including how the paper clips aren’t really floating but are actually being supported by the force of surface tension. There are also document camera images and notes on surface tension that relate to aquatic insects that use surface tension.
This resource also provides a student question sheet for students who finish early. The questions focus on the two forces involved in the activity: gravity and surface tension. Answer key included.
This individual resource is also part of an all-inclusive bundle for the topic of surface tension. You will save a full 25% on each resource when you purchase this bundle!
