Bernoulli Effect with Paper Strips Lab Sheet
Hold two paper strips next to each other, turn on a hair dryer, and watch them move toward each other instead of apart. The Bernoulli effect with paper strips makes abstract fluid dynamics instantly visible.
This lab sheet walks your student through a seven-step experiment testing how moving air changes pressure between two hanging paper strips. Students record what happens when the fan or hair dryer blows upward between the strips, then adjust the distance between them and observe whether the effect changes. A dedicated hypothesis section asks students to predict behavior before the air turns on, and the observation section prompts three separate written responses. Designed for grades 4-7, it closes with an “Explain It” prompt requiring students to apply the concepts of air speed and pressure in their own words.
The Bernoulli effect with paper strips fits naturally into a physics or forces unit study, and it pairs well with lessons on lift, flight, or fluid dynamics. Your homeschooler can complete it as a standalone introduction to pressure concepts or as an anchor activity before studying airplane wing design. A real-world connections section at the bottom asks students to identify at least two applications, from airplane lift to sailboat propulsion, giving the experiment genuine transfer value beyond the tabletop.
Grades 4-7 homeschoolers test the Bernoulli effect with paper strips and a hair dryer. Includes hypothesis, observations, and real-world connections.
Getting Started with the Bernoulli Effect with Paper Strips
Usage Notes
Nearly everything on the materials list is already in the house: paper strips cut to size, scissors, a ruler, and optional tape. The one item worth checking is a hair dryer with a cool or low-heat setting, since the safety section specifically calls for that setting and reminds students not to look into the airflow. An adult should supervise the hair dryer steps, particularly for younger homeschoolers.
Printing Tips
Standard 20 lb copy paper works for most students, but 24 lb paper keeps the writing lines crisp if your student presses hard with a pen. Slip the sheet into a lab notebook after the experiment, or use a clipboard during the active steps so the sheet stays flat while both hands hold the paper strips.
