STEM Activity
Have you ever seen a water strider (also called water bugs, pond skaters, water skippers etc.)? They are bugs that effortlessly hop around on the surface of ponds, lakes, and rivers. How do they do it without sinking? Try this project to find out! Read more
Blog Post
Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure... exploring surface tension by making wire water striders. A Spill Leads to Exploring Surface Tension What happens when you put a freshly laundered tablecloth on the table? Well, in my house, it immediately triples the chance that someone will… Read more
Blog Post
Join Science Buddies this summer for virtual summer camp! Each week, we'll have a fun STEM theme for kids of all ages, suggestions for simple hands-on activities, book picks, and more. With our Summer of STEM, we'll keep you and your kids inspired all summer with creative and innovative science and engineering activities — for free. This week: make a splash with water play and water-based science experiments! Water Play Science Week 6 focuses on… Read more
Lesson Plan Grade: 3rd
How do water striders skip across the surface of the water? What advantage does this give them over other insects that helps them survive in their environment? Your students will find out in this lesson as they build their own insects from pieces of wire, and see which ones sink and which ones float. Read more
NGSS Performance Expectations:
  • 3-LS4-3. Construct an argument with evidence that in a particular habitat some organisms can survive well, some survive less well, and some cannot survive at all.
Science Fair Project Idea
Water striders (also called water bugs, pond skippers, etc.) are insects that can hop around on the surface of water (Figure 1). Unlike boats or other floating objects that are partially submerged and held up by the resulting buoyant force, water striders are held up by surface tension. Figure 1. Water striders (image credit Isaka Yoji). You can build your own water striders using thin wire (Figure 2 and following video). Do some background research… Read more
