8 Simple Experiments to Learn about Density

Science Experiments at Home: Liquids

Does it sink or float? And why do some liquids mix together easily (think lemon juice and water for some tasty lemonade), when others don’t mix together at all?

Here is a list of nine simple science experiments that deal with density of various objects and liquids. Enjoy!

Density Experiments – Does It Float or Sink?

It’s fun to experiment with various objects to determine if they will sink or float and then to speculate why.

Science Experiments at Home: Liquids

The Floating Egg – Eggs naturally sink in water, but we made them float by adding one simple ingredient to the water. Want to know what it was? Find out here.

Why Does the Heavier Orange Float? – Use this experiment to show that the weight of an old isn’t the indicator to use to determine if it will sink or float.

Science Experiments at Home: Liquids

What causes some pop cans to float and some to sink? – All the pop cans are the exact same shape, size and weight, but why do some of the cans float while others sink?

Density Experiments – The Density of Different Liquids

Not only is it fun to experiment with the density of various objects, but it’s also pretty amazing to experiment with the density of different liquids.

Science Experiments at Home: Liquids

Rainbow in a Jar – This is one of our all time favorite density experiments. It takes a little pre-planning to ensure you have all the necessary liquids on hand, but the end result is quite fascinating.

Science Experiments at Home: Liquids

Mixing Oil & Water – Will the two liquids stay mixed together? Only if you add a third ingredient into the mix! Do you know what it is?

Science Experiments at Home: Liquids

Homemade Lava Lamp – This is another fun experiment that shows how oil & water don’t mix. Then it takes it one step further by adding one extra ingredient that causes a cool chemical reaction and results in the “lava lamp” experience.

What about you? Do you have any favorite experiments that you use to teach about density? I’m always looking for new ideas, so it you have one, leave a comment below. Thanks!

Liquid Science Experiment

If you follow along regularly, you know that we host a series called 12 months of sensory dough where we and 12 other bloggers try out a popular dough and present a spin to the recipe. Here at Lemon Lime Adventures, we love science. So, naturally we did a liquid science experiment to prepare for our Cloud Dough.

I am so excited to be the newest member of Saturday Science Blog Hop with 3 other amazing blogs. I decided to join along, as motivation to post all the fun science experiments, activities, and learning we are doing each week.

This week I am excited to share our experiment with liquids when we made our recent Cloud Dough recipe.

Setting up the Liquid Science Experiment

 This month our dough experiment was to determine which liquid would be best suited for our Cloud Dough Recipe. In our liquid science experiment, we talked about variables and constants in experiments.

{A variable is the part of the experiment that you are going to manipulate and change; while the constants are the part of the experiment that will remain the same from trial to trial. }

After determining the correct ratio for our recipe, we chose 4 liquids to test. (I chose the liquids so the boys had to investigate and compare them without knowing what the liquids were.)

I chose:
Baby Oil
Vegetable Oil
Corn Syrup

Baby Lotion

To prepare, I put each liquid in a glass container and set out 4 bowls, hid the containers the liquids came in, and explained the experiment to the children. The vocabulary I focused on was variables, properties, and viscosity.

Observing the Liquid Properties

  • Science Experiments at Home: Liquids
  • Step One: Explore the various liquids and describe them.
  • We talked about the colors, the thickness, and the ability to see through the liquids.

I asked questions such as: “What do you notice?” “How does it move?” “How is it the same or different than…” “What happens when you look through it?”

For 10 easy questions to ask during a science exploration, you can read my Getting Started with Science post.

Both boys (age 6 and 8) really wanted to guess the liquids, but at this point I wanted them to focus on describing the properties and comparing each one.

Science Experiments at Home: Liquids

Step Two: I introduced our vocabulary.

Instead of using thick, slow, or sticky… I presented them with Viscous. They were able to understand that viscosity is a way to describe a liquids movement against gravity (it’s thickness)

Matching Liquids to Real Word Items

Science Experiments at Home: Liquids

Step Three: Matching liquids to their real world examples.

Now was the time we got to math the liquids. The boys loved this step. They loved finding out that the oil was not water. This surprised them (although they suspected it wasn’t water because of the properties they had noticed)

  1. Science Experiments at Home: Liquids
  2.  Step Four: Ordering Liquids By Properties
  3. The last stage before experimenting with our liquids was to compare the viscosity of the liquids and order them least to greatest.

We did this so that we could determine and predict to outcomes each liquid might have on our Cloud Dough.  We made labels for each liquid and predicted how the thickness of the liquid might effect the cloud dough mixtures.

Which Liquid Makes the Best Cloud Dough?

Step Five: Create 4 different Cloud Dough Recipes

Finally, we used our liquid science experiment to make our cloud dough recipe. Be sure to read more to find out which liquid worked best!

Science Experiments at Home: LiquidsAren’t you curious which liquid we used to Create the Perfect Cloud Dough?

Tip: Don’t let the vocabulary scare you or your kids.

I am a strong believer that even children at a very young age can be exposed to academic language and provided hands-on experiences to understand it. This activity would be suitable for children preschool through elementary. The level of guidance and support might need to vary, but science and learning can be fun!

Home Science Experiment For Students: A Fun Density Experiment

  • Equipment;
  • Three empty jars
  • One tall glass or jar
  • A small measuring jug
  • 100ml golden syrup
  • 100ml sunflower or cooking oil
  • Some food colouring

Lots of small objects. Examples:- piece of Lego, small piece of wood, a metal screw, coin, pebble – anything that can be easily washed.

You could also try this with honey or washing up liquid.


Weigh the first jar and write down the result. Measure out 100ml of golden syrup and pour into this jar. (It is a bit easier to do this of the syrup is a little warm).

Science Experiments at Home: Liquids

Weigh the jar again with the golden syrup in it and record this weight. Take away the first weight from the second weight and this will tell you how much the golden syrup weighs.

Science Experiments at Home: Liquids

Repeat step 1 with oil.

Science Experiments at Home: Liquids

Repeat step 1 with water and add a few drops of food colouring.

Compare the weight of 100ml of syrup, oil and water. Do they all weigh the same?

Pour each liquid into the bigger jar. What happens?

Science Experiments at Home: Liquids

Each of the layers will be a separate liquid. This is because the densest liquid has gone to the bottom, the least dense liquid has floated on the top. How does this compare to the weight of each liquid?

Now, take your first object. Predict which layer you think it will float on. Try it and see if you are correct. Interestingly, some things that seem light will sink and things that seem heavy will float.

Science Experiments at Home: Liquids

The science behind this experiment is all about density

Everything is made up of molecules. If these molecules are packed tightly together in an object, then that object is dense. If the molecules are further away from each other, then that object is less dense. This is the same for a liquid.

Objects or liquids float on liquids that have a higher density.

The plastic counter will sink through the oil but float on the water; the coin will sink through both; therefore, the coin is denser than the plastic counter and it is also denser than the oil and the water.

Fluids in Motion | Fun Science Experiments

Daniel Bernoulli (1700-1782) was a Swiss mathematician and physicist best known for his work involving fluid dynamics. He began studying fluids because he was interested in studying the pressure and flow of blood in the human body.

His painful method of measuring blood pressure involved inserting a hollow glass tube directly into a patient’s artery and measuring the height of the blood pumped into the tube with each beat of the heart. Thankfully, this method of measuring blood pressure was replaced by the less-painful blood pressure cuff invented by Scipione Riva-Rocci in 1896.

Science Experiments at Home: LiquidsWhen a fluid is moving faster, it has lower pressure. This principle explains the lift created by an airplane’s wing. (Image credit: NASA Quest.)

From his experiments, Bernoulli concluded that when a fluid is moving faster, it has lower pressure.

This is known as Bernoulli’s Principle, and it is used to explain many scientific ideas from the movement of weather systems to the lift created by an airplane’s wing.

The following simple demonstrations will allow you to play with some fun toys and learn a bit about the natural science of fluids (liquids and gases) in motion. [Countdown: Easy Answers to the Top 5 Science Questions Kids Ask]

Experiment 1

A fluid stream that comes in contact with a gently curved surface will tend to follow that surface.

Science Experiments at Home: LiquidsA fluid stream that comes in contact with a gently curved surface will tend to follow that surface. (Image credit: thomas eder Shutterstock)

Run a gentle stream of water from a faucet. Holding a tablespoon parallel to the running water, gently introduce the curved back of the spoon into the running water.

What happens to the stream of water?

Turn the spoon around so the bowl side of the spoon is in the stream — How is the result different? On which side is the water moving faster?

Experiment 2

A faster-moving fluid has less pressure than a slower-moving fluid.

Even though you can’t see it, air is a fluid! When a column of air is moving faster than the air around it there will be less pressure where the air is moving quickly.

What you will need:

  • 2 pingpong balls
  • 2 pieces of thread about a foot long
  • Tape
  • Soda straw

What to do:

Tape the thread to the pingpong balls and suspend the balls from a towel rack or bar so that they are about a half-inch apart. Use the soda straw to blow a column of fast moving air between the balls.

In what direction do the balls move? If the swift moving air between the balls has less pressure than the rest of the air in the room, how does this explain what happened? Try moving the balls closer and farther apart. How does this change what happens and why?

Experiment 3

  • How to fool your friends using Bernoulli’s Principle
  • What you will need:
  • What to do:

Place the pingpong ball on the table and put the funnel over it. Challenge your friends to turn the funnel right side up with the ball in the funnel — without touching the ball or scooting the funnel to the table edge.

See also:  How to work with negative exponents

This trick takes some practice and a lot of wind power — but you should be able to blow into the narrow end of the funnel to lower the pressure inside, raising the ball high enough to turn the funnel right side up! Remember you have to continuously blow into the funnel as you turn it!

Experiment 4

How does Bernoulli’s Principle explain how the shape of an airplane wing creates lift?

What you will need:

  • A sheet of typing paper
  • A piece of thread or smooth string about a yard long
  • A hole punch or sharp pencil
  • Tape

What to do:

Make a sharp crease in the typing paper about a third of the way up from the bottom.

Unfold the crease and tape the top edge of the paper to the bottom edge. You should now have an airfoil shape with a flat bottom surface and a gently curved top surface.

Using the curved part as the front of your airfoil, and the narrow taped edge as the back, punch a hole in the top and bottom of your airfoil. Thread the string through the holes.

Hold the string vertically with one end in each hand and the airfoil at the bottom of the string. Spin in a circle or run and watch your airfoil rise up the string.

Is the air moving more quickly over the top of the curved paper or under the bottom flat side? How do you know? Look closely at the wings on an airplane. What is the shape of the wing? How does this help explain how a heavy airplane can fly?

Experiment 5

How does a helicopter create lift?

What you will need:

  • Typing paper
  • Ruler
  • Pencil
  • Scissors
  • Small paperclip

What to do:

Science Experiments at Home: Liquids(Image credit: NASA Quest.)

  1. (See illustration)
  2. Cut a rectangle 4 by 8 inches (10 by 20 centimeters) from the sheet of typing paper.
  3. Cut a straight line down the middle of the rectangle — stop almost half way down.
  4. About one-eighth inch from the bottom of the first line, cut slits about one-and-a-half inches from the edges of the paper.

Fold up along the dotted lines so that the “X” and “Y” rectangles make the stem of the rotor. Then fold the bottom edge “Z” up a quarter-inch and add a paperclip to it for weight.

Fold rectangle “A” upward. Fold rectangle “B” downward.

Drop your helicopter from overhead and watch it spin slowly to the ground.

Where is the air moving more quickly? What force is making the air move? How does this create lift? If you live in an area where maple trees are common, study their “helicopter” seeds in the spring. What would be the advantages of this seed dispersal system?
