What is Density?

The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho). Mathematically, density is defined as mass divided by volume. 

where ρ is the density, m is the mass, and V is the volume

 Density is a physical property of matter that expresses a relationship of mass to volume. Different materials have different densities.

Evaluating Density of Three Different Liquids

Here we will particularly discuss the density of three different liquids namely water, honey and oil with a simple experiment.

Density of these following liquids are:

Water : 1 g/cm³

Honey : 1.43  g/cm³

Oil : 0.926 g/cm³

Materials Required for the Experiment:

1)Test tube / Beaker / Transparent white plastic cup / Glass cup

2) Water

3) Honey 

4) Cooking oil

Procedure for the Experiment:

1)Take a test tube/ Beaker / Transparent white plastic cup / Glass cup and add water

2) Add honey to the water in the test tube

3) Add oil to the same test tube

materials and procedure to measure and compare density of 3 different liquids

Observe the layers of different liquids. It’s happening because the density of the three liquids are different. Now you know how the densities of the three liquids compare to each other. If you want to find out the approximate density of each, you can calculate it using this formula : Density = Mass/Volume.

Science Experiment for Density at Home

Try at home and learn about the concept of density more clearly with these 3 science experiments:

Experimenting with Eggs

Take 2 eggs of roughly the same size and weight. Fill a tall drinking glass with 3/4 water. Put an egg in it. Observe and record what happens. Take another glass and fill it with the same amount of water. Put 3 tablespoons of salt in it and stir well until fully dissolved.

Put another egg in it. Observe and record what happens. Compare your observations and understand why one egg floated and the other sank.

Shape of the Clay Matters

Fill up a tub full of water. Take a ball of clay or Playdoh and put it inside the tub. Observe and write down your finding. Take another piece of clay and this time try to give it a shape. You can flatten it out and fold its edges to give it the shape of a boat or a kayak. Try putting it inside the tub again.

Does it float or sink? Does shape have anything to do with the density of the object? The answer lies in your observation!

Can an Orange Float?

Take an empty glass jar and fill it with water. Take an orange and put it inside the jar. What happens to the orange? Does it sink? Wrote down your observation.

Peel the orange and put it in another jar filled with water. Do you notice a change in the density of the orange. Write down the difference between the two events and observe the change. This is a very simple science experiment that any child can try out, regardless of age!

Your Takeaway

Measuring density is no biggie but observing it hands-on with these super easy and fun science experiments can actually have a big impact to your learning and understanding of the magical subject that is science! These experiments are safe and can be performed at home for kids of all age groups.

Who knows, while performing an experiment you uncover something that no one else had an eye for, yet? All the best!
