We always love a good oil and water exploration moment during mad science week but this year changed up the water color to fluorescent pastels. We provided two different trays with a base of oil 1) In a clear pyrex dish on a light table to let the magic of light enhance the experience 2) In a white serving tray to make the colors really pop. In our paint tray we placed a drop of Colorations® Fluorescent Paint mixed with White Liquid WaterColors & provided pipettes. We invited the children to take the pipettes, fill them up with colored water & drop it into the oil to explore what happens.
Through this exploration they were able to explore how oil remains separate from the water because it lacks polarity & floats because it’s less dense. We explained that when you have two objects that are the same size but different weights, the one that weighs more has more matter packed into it. It is denser. A good way to tell if something is more or less dense than water is to put it in water. If it sinks, it’s denser, if it floats, it’s less dense.
Through these type of experiments, children can visually see and learn many important science concepts. These hands-on activities can help them develop skills such as problem solving, critical thinking, and decision making too. Children can also practice asking questions, observing, analyzing the results, drawing conclusions, and much more. These skills will help your children in all areas of learning!
