Paper Towel Absorbency Test – Scientific Method Lesson

About this resource

What's inside this resource

A hands-on paper towel absorbency experiment asks students to test three paper towel brands by timing how much water each absorbs from a graduated cylinder, then record results in a data table, graph the averages, and write a conclusion and reflection. It is bundled with a broader eight-step scientific-method unit covering questioning, variables, hypothesis writing, planning, performing, observing, analyzing, and discussing, delivered as a student slide deck with blanks to fill in alongside a matching teacher slide deck and PDF that already contain the completed answers, plus a five-page written lesson outline covering the same content with practice examples like the 'Burger Power' control-group scenario. A one-page extension activity suggests ways to make the absorbency experiment more advanced, such as testing multiple liquids, timing absorbency, or comparing regular versus stronger towel varieties. The bundle also includes a document of outside links to the vendor's own website and a YouTube video, plus a one-page promotional insert offering additional free resources from the same author outside of Teach Simple.

Paper Towel Absorbency Test - Scientific Method Lesson Included

This engaging activity introduces students to the scientific method through an experiment involving a common household material - paper towels.

Students will form a hypothesis about which paper towel will be the most absorbent. They will then collect data by placing different paper towel brands into a liquid to see the effect.

Your students are provided with clear procedures that will guide them to record their results in a well-organized data table and graph. As a class, data can be compiled and percentages calculated to identify trends.

Students learn important data analysis skills as they create graphs to visually represent the results. Educators will appreciate the post-experiment reflection questions that reinforce the purpose and process of the scientific method.

This hands-on lab nurtures students' natural curiosity while teaching fundamental experimental design. With its real-world topic and tactile investigation, it motivates learners across various grades and learning styles.

After completing the activity, students will better understand how to use observation, critical thinking, and representation of evidence to answer a testable question.

Additionally, this resource includes my lesson on the Scientific Method. The lesson includes a detailed overview of what the scientific method is as well as how to implement it.

In the classroom

Teaching tips & learning objectives

Learning objectives

Design and carry out a controlled experiment testing paper towel absorbency across three brands
Identify independent, dependent, and controlled variables and a control group within a given experiment scenario
Write a testable if/then hypothesis for a given research question
Record data in a table, calculate averages, and graph results following correct graphing conventions
Draw a conclusion from experimental data and reflect on ways to improve the experiment

Teaching tips

Use the Student Lesson Outline and student slide deck to teach scientific-method vocabulary before assigning the paper towel experiment as the applied task
Keep the teacher-version slide deck and PDF (with completed answers) separate from what students see, since they are otherwise identical to the student deck
Use the Lab Extension Activity ideas, such as timing absorbency or testing other liquids, for early-finisher groups
Review the embedded 'Burger Power' control-group example together, since it is used as a practice scenario for identifying variables before students design their own experiment

Skills covered

Experimental design — students plan a controlled test comparing three paper towel brands using a graduated cylinder and timer.
Variable identification — students distinguish independent, dependent, and control-group elements in the 'Burger Power' practice scenario and their own experiment.
Hypothesis writing — students write if/then hypotheses such as predicting which towel brand will absorb the most water.
Data graphing conventions — students apply rules for titling, labeling, and scaling a graph of their absorbency averages.

Good to know

Questions teachers ask about this resource

How do the student and teacher slide decks relate to each other?

They cover identical scientific-method content, but the student version leaves blanks (e.g., for variable definitions and hypothesis examples) while the teacher version and its matching PDF already contain the filled-in answers.

What does the 'Burger Power' scenario ask students to identify?

It is a practice case about a new burger sauce tested on two groups of 100 customers, asking students to name the independent variable, the dependent variable, and which group serves as the control.
