Cubs, you know all liquid has mass and density. In simpler words one can say they all have weight. Bud does all liquid weigh the same? Let’s perform an experiment to see density of different liquids. Also, let’s toss in some everyday object to see what sinks and what floats.
Cubs, you know all liquid has mass and density. In simpler words one can say they all have weight. Bud does all liquid weigh the same? Let’s perform an experiment to see density of different liquids. Also, let’s toss in some everyday object to see what sinks and what floats. Firstly, put together the below materials.
Coloured water – 1/3rd of a glass
Honey - 1/3rd of a glass
Oil - 1/3rd of a glass
Olive – 1
Lego piece – 1
Pebble - 1
Take a glass and fill it with coloured water. Fill about 1/3rd of the glass. Now take honey and start pouring it. Again, pour so that only 1/3rd of the space is left. You will see that the honey will get settled at the bottom pushing the coloured water above it. Now, lastly start pouring oil. Be careful while pouring it, don’t bring it to the glass top as we don’t want a spill. Once you pour oil you will notice that the honey sits at the bottom, coloured water at the center & oil floats on the top.
Now, the second part which is tossing some objects in it to play sink or float. Let’s begin by putting a stone you will see it goes right to the bottom. Now add an olive, it will settle in water. Add a Lego piece it will float on oil.
So, what’s happening? Well, through this experiment we understood all liquids have different density. Due to the difference in the density different object sink or float in them. And that is why the following happened:
- The pebble sank and settled in the layer of honey
- The olive sank in coloured water, but floats on the layer of honey.
- The piece of lego floated on top of oil layer.
This implies that in liquids honey is with the greatest density, water is lighter than honey but heavier than oil. Oil is the lightest and that’s why it floats on top of honey and coloured water layers.
Cubs, you can try this experiment with different things available. For liquids you can try maple syrup, corn syrup, milk, vinegar etc. For sinking and floating exercise, you can use coins, rings, dice, grape etc.
Obviously, the result will differ as per the weight of the objects. Hope you enjoy learning about the density of liquids through this super simple experiment.
