Hi All


With regards to the experiment on surface tension of water, might be good to teach your child to apply that concept instead of just learning it. In Science exam nowadays, application of concepts is v important.

For e.g., how does spraying insecticide on water kill the mosquito larva and pupa? It's a common misconception among kids that the breathing tubes are blocked so the larva and pupa died because they cannot take in air, but in actual fact, it's because insecticide lowers the surface tension and cause the larva and pupa to drown.
Plus you can also introduce the idea of how some insects seem to be able to float or walk on water surface like the water skater. Hope this information is helpful to you.
