STEM Lab / Project - Water Surface Tension - Critter Race Activity for Physics

In this STEM (Science, Technology, Engineering, and Math) lab, you’ll be swimming in science as you try to break water’s surface tension and send magical critters sailing away! Students learn about surfactants and how they affect water tension by adding different liquids to one of six floating paper critters to see if they can make the critter move.

Check out our Getting Nerdy Blog Post showing the critters in action!

This lab is open ended, providing teachers the ability to choose how to conduct the activity. Students can work in groups, independently, or as a whole class. Students will collect data on distance, time, and calculate speed. They then create a graph under their teacher's instruction and analyze their data with extension questions. Answer key is not included because YOU decide how to best test the surfactants and critters. However, background information is provided to easily answer questions.

to see state-specific standards (only available in the US).
Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
