Water Strider Challenge: Make a Bug Walk on Water!
Get ready to be amazed as you create your own insect that can walk on water. Water striders are able to do this thanks to their hydrophobic legs and high surface tension of water. The experiment will challenge you to use the engineering design process to identify the problem, prototype, create/test, and improve your water strider.
The hypothesis is that by using materials provided, you can engineer their own water strider that will float and walk on water.
Method & Materials
You can use a variety of materials to create your own water strider. Think about how bugs look in real life and what helps them float. Aluminum foil can be used to make all parts of the bug. Styrofoam can work well for feet and wire or pipe cleaners for legs, but it’s up to you to decide what to use. The goal is to create a water strider that can float on the water.
You will need wire, pipe cleaners, aluminum foil, straws, Styrofoam balls, markers, scissors, construction paper, tape, and water containers.
In conclusion, the water strider experiment taught us that bugs can use their hydrophobic legs and the high surface tension of water to walk on water. One observation that stood out was the importance of increasing surface area to decrease pressure and help the water strider stay afloat.
Why do this project?
This science project is interesting because it challenges you to think about how nature works and use engineering to mimic the way bugs walk on water. It also teaches you about surface tension, hydrophobicity, and the engineering design process.
1) Try to get your water strider to float on different liquids or 2) Add soap to the water and watch what happens.
