Plan a Fair Test: Paper Airplanes

Set out the materials listed on each sheet and run three trials as the steps say, so students see why repeated trials matter. Do the experiments with a grown-up nearby. Have students fill the data table before they graph, then write the conclusion from the numbers, not from their guess. The science fair planner works as a six-week checklist students can keep in a folder.

Seven experiment and data worksheets for 3rd to 5th grade. 3rd grade students test the absorbency of three paper towel brands and graph the results, and use a two-page experiment record sheet for their own test. 4th grade students plan a fair test with paper airplanes, flying three wing designs three times each, and plot plant growth data on a line graph. 5th grade students read pendulum data and write a claim with evidence, time how fast sugar dissolves in three cups of water, and plan a science fair project over six weeks. The line graph and pendulum data sheets have answer keys.

Yes, both. We made it for 4th Grade scientific method, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with experiments and data. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Doing a test three times shows whether a result was a fluke. Students add or average the trials, so one odd result does not change the conclusion.

A testable question, research, a hypothesis, materials, steps, data from several trials, a graph and a conclusion. The 5th grade planner spreads these over a six-week checklist and maps them onto a display board.

3rd, 4th and 5th grade: five sheets for 3rd grade, four for 4th grade and four for 5th grade. Sheets for Kindergarten to 2nd grade are on the 1st grade scientific method page.

Ask a question, do research, form a hypothesis, test with an experiment, analyze the data, and draw a conclusion and share the results. The 3rd grade steps sheet has students put them in order and match each one to part of a ball-bounce experiment.

Use the frame If, then, because: if I change this, then this will happen, because of this reason. The if part is what you change, and the then part is what you measure. The hypothesis sheet walks through one example, then gives four testable questions to try.

A fair test changes only one thing and keeps everything else the same, so you know that one change caused the result. The thing you change is the independent variable, what you measure is the dependent variable, and what you keep the same are the controlled variables.

Eight of the thirteen do, the ones with a right answer, such as ordering the steps, observation or inference, and identifying variables. The experiment sheets and the science fair planner use each student's own data, so they have no key.
