Exploring Sand Dunes

At Girlstart, we love to have fun in the sand and sun and learn STEM skills at the same time! Did you know there are four different types of sand dunes? Or that there is a sand dune in China that migrates at a rate of 100 feet every year? At this week’s After School To-Go, girls studied different types of sand dunes and learned about the formation process that leads to each shape.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Each group of girls used straws to mimic the shaping effect of wind, then shared their results with each other. Students discussed the negative effects of sand movement, including damage to towns and health risks. The girls suggested various protective methods, then designed and tested their solutions.

 

 

After testing their ideas, students compared their results once again. Even while having fun, Girlstart girls are using geology skills to solve nitty-gritty problems!
