Scientists use droppers but call them pipettes. Pipettes come in many different sizes and styles but they all do the exact same thing: suck up a liquid and release it on command.
To use a dropper you have to pinch the bulb, put the tip in the liquid, release the bulb so it can draw in the fluid and then remove the tip and squeeze the bulb again. That is a lot of steps. With practice kids can get pretty good at it.
So now your child has mastered the dropper. What can they do now?
Try dropping paint from different heights to see the splatter pattern
Try dropping water with food coloring into a clear cup of oil (from above and below the surface)
Try putting different drops of colored water into a single cup to see them mix
Try putting chocolate syrup into your milk (this might need to be thinned a bit, test first)
Try putting syrup into squares on your waffles
Share your experiences with droppers below!
