Featured Photographer: Sierra. Thank you for sharing these beautiful photos from your nature walks last week, Sierra!
Today is Wednesday, which means it is time for another mystery science!
This week’s mystery science we will explore how solid rock breaks apart into smaller pieces through a process called weathering (including root-wedging and ice-wedging). In the activity, Sugar Shake, you can use sugar cubes as a model for rocks. Then you are invited to perform an experiment with this model to understand the process of weathering and how this process explains why rocks at the tops of mountains are jagged, while those at the bottom are rounded.
- Watch this video
- Try the experiment! (if you don’t have any sugar cubes, you can just make the predictions! You can also click here to see a video of someone doing the experiment – with some bonus content too!)
- Reflect on your learning with the attached form.
4. Try these extensions (optional):
- Go on a Plant Walk – look for plants that have taken root where humans might think they “don’t belong”. You may find grass growing in cracks in a sidewalk or plants sprouting between stones or bricks in a wall.
- Check out this 10-minute video from Yosemite National Park which shows what happens when rocks break off a steep slope.
- Read this article called 2,500 Tons of Rock Fell Off Half Dome.
- Discover this demonstration involving “Mighty Beans”!
Today we are also launching Hana & Yannes’s Art Contest!
