Friction Lab: Home Experiments in Science

Grade 5Science1 days
The 'Friction Lab: Home Experiments in Science' project is designed for 5th-grade students to explore and understand friction through hands-on experiments. By conducting these experiments at home, students will measure how different factors such as surface type, material, and surface area affect frictional force. The project encourages scientific inquiry and observation, aligning with Next Generation Science Standards. Through activities like the DIY Skating Rink Experiment and Friction Measurement Mania, students will analyze friction in everyday contexts and document their findings, ultimately enhancing their understanding of physical science concepts.

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Understand and define friction as a force that opposes motion between two surfaces.
  • Identify and describe factors that affect the force of friction, such as surface type, material, and surface area.
  • Conduct and document home experiments to measure friction in various contexts and analyze the results.

  • Develop skills in scientific observation, measurement, and data analysis through experimentation.

Next Generation Science Standards

5-PS2-1
Supporting
Support an argument that the gravitational force exerted by Earth on objects is directed down.Reason: Understanding friction requires a grasp of forces such as gravity, which plays a key role in experiments measuring friction.
5-PS2-2
Primary
Make observations and measurements to produce data to serve as the basis for evidence for an explanation of a phenomenon.Reason: Conducting experiments to measure friction involves making observations and collecting data, which aligns well with this standard.
5-PS1-3
Secondary
Make observations and measurements to identify materials based on their properties.Reason: This standard supports the project's goal of understanding how different materials affect friction.

Entry Events

Events that will be used to introduce the project to students

DIY Skating Rink Experiment

Transform a section of the schoolyard or classroom into a 'skating rink' using different materials to simulate ice and other slippery surfaces. Challenge students to design solutions that increase or decrease friction to prevent skaters from falling, using household items for testing.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

Friction Measurement Mania

Students will measure the force of friction by applying force to move objects with spring scales and analyze the frictional force experienced by different materials.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Provide each student/group with a spring scale and various surfaces and objects (rubber ball, wooden block, metal sphere).
2. Instruct students to pull each object across the surface using the spring scale to measure force.
3. Record the force needed to move each object over different materials.
4. Compare and analyze how different surface materials and the objects themselves affect the force measurement.

Final Product

What students will submit as the final product of the activityA data chart showing the different forces required to move objects over various surfaces.
