Free Printable Lab Report and Scientific Method Sheets

About these lab report and scientific method sheets handouts

Students write better lab reports when the structure is in front of them. The lab report page walks through the standard parts in order: a question, a hypothesis, materials, a numbered procedure, a data table, an analysis of the data and a conclusion. The data table has columns for three trials and an average, since repeated trials are one of the habits worth teaching early.

The scientific method sheet lists six steps taught in many classrooms: ask a question, do background research, form a hypothesis, test with an experiment, analyze the data and draw a conclusion, and communicate the results. Each step has a short prompt and room for students to write how they used it in their own investigation. A dashed arrow shows the loop back to the hypothesis when the results do not support it.

That loop matters, and so does the note printed at the bottom of the sheet. Real science does not follow a single fixed list of steps. Researchers move back and forth between steps, skip some, repeat others and often work on several questions at once. The sheet is a planning guide for a classroom investigation, not a description of how every scientist works.

The experiment planner is for the stage before the lab report. It asks students to name what they will change, what they will measure and what they will keep the same, then to plan materials, how to record results, how many trials to run and what safety steps to take. Planning variables first prevents the most common problem in student experiments, which is changing more than one thing at once.

How to use them

1. Pick the page for the stage you are teaching: planner before the experiment, steps sheet while teaching the process, lab report after.
2. Fill in class, teacher and unit boxes, then print one copy per student or lab group.
3. Have students complete the planner and show you before they collect materials.
4. During the lab, students record data in the table as they work, not afterward from memory.
5. After the lab, students finish the analysis and conclusion, using their data as evidence.

Classroom tips

• Have students underline the one variable they will change on the planner. If they underline two, the plan needs work.
• Run the steps sheet on a familiar question, such as which paper towel holds the most water, before starting a real experiment.
• Ask students to write one sentence in the conclusion about what they would change next time. It builds the habit of treating results as the start of a new question.
• Post the note about real science next to the steps poster so students see the steps as a guide, not a rule.

Notes on this page

• Real science does not follow one fixed list of steps. Scientists move back and forth, skip steps and repeat them, so use the steps as a guide for planning.

Where the facts come from

• Science Buddies: Common classroom list: ask a question, do background research, construct a hypothesis, test with an experiment, analyze data and draw a conclusion, communicate results
• Understanding Science, University of California Museum of Paleontology: Science is not a rigid linear sequence of steps; the real process is flexible and iterative
