Road Paint Weathering

Weathering and erosion impact natural and manmade objects alike. In this phenomenon, you will see evidence of weathering and erosion on road paint. 

Location
Sioux Center, Iowa

Possible Guiding, Compelling and/or Anchoring Question

  • What could cause the paint to weather?
  • Where do you think the paint went?
  • How long do you think it took for the road paint to get this way?

Classroom Suggestions

Students could: 

  • Color on a white board with dry erase markers, then put different substances like ice, sand, or water (hot or cold), in a bag with the board and shake it around to see what happens. Have another student time the interval of shaking. Students could record what they predict will happen and then what actually happens. After they record the results, they can repeat the process with different time intervals. When students have completed their predictions and the activity we will talk as a class about what this might look like in real life. We will talk about road paint and how it changes over time with different natural elements. 
  • Use an observation sheet to observe weathering at home and give them prompts for noticing and wondering.
