Product description

From the author

Explore force and motion by predicting and observing how different balls begin to roll when blown.

This is a Force and Motion Science Experiment for your students to take part in.

It may be used best with 3rd – 5th grade students.

Students will work with a set of balls to apply what they know about force and motion. Students will complete the 2 page printable along the way.

They will begin by making a hypothesis, as scientists do, before engaging in the experiment. Students will hypothesize which ball they believe will need the most wind-force for motion and which ball will need the least wind-force. You may choose to have your students decide on this hypothesis individually or in small groups.

When students have wrapped up their hypothesis, they will move forward into the experiment portion. Students will follow the directions on page 1 to test out the force and motion of each ball. There is space for them to test out 6 balls. Your class may love completing this in small groups or with a partner.

On page 2, they will reflect on the experiment by writing their particular outcome and formulating a conclusion about the wind-force needed to put balls in motion.

I hope you enjoy!

Teaching tips & learning objectives

Learning objectives

  • Formulate a testable hypothesis about how a ball's physical properties affect the force needed to move it.

  • Apply increasing force (breath) to an object and record the point at which motion begins.

  • Compare experimental outcomes to an original hypothesis and revise thinking based on evidence.

Teaching tips

  • Gather six balls and use the same flat surface for each trial.

  • Model the soft-to-vigorous rating scale.

  • Discuss how several ball properties change at once, limiting conclusions about any one property.

Skills covered

  • Making predictions

  • Recording qualitative observations

  • Comparing outcomes with a hypothesis
