Science for kids is among our favorite topics, and also this science activity is a fun one! kids will have actually fun predicting how numerous paperclips they have the right to fit in a full glass of water, and also actually do the efforts it the end for themselves. This science experiment exploring the surface ar tensionof water always seems to surprised the kids!

Welcome to an additional invitationto explore science! critical week we had fun v Dancing Raisins! This main we space going to check out the surface stress and anxiety of water. It’s an experiment that’s certain to inspire a sense of wonder and curiosity in her child! (This post contains affiliate links. Give thanks to you so much for your support!)

### Tips

This is dubbed surface tension. Once too many paperclips were added to the cup, the surface stress and anxiety was broken, permitting the water to pour out over.

### Want to go even further?

Even much more activities come inspire creative thinking and vital thinking for assorted ages.

Try this experiment making use of something various other than paperclips. Were the results comparable or what friend expected?Devise methods to quickly keep track of count the paperclips. (Ex. Tally marks, number chart etc.)Make a perform of an ext questions the you thought around as you did this science activity.Try a comparable experiment.
