Science is Fun: Oil and Water Experiment

Science is fun. When a child is able to put their hands on something and find out how it works and why it works they learn so much better. What is more exciting than trying something out on your own? This month we want to share a fun science experiment that will allow your kids to discover the difference between oil and water.

Thank you to Growing a Jeweled Rose for creating such a fun and unique way to interact with water and oil. This new experiment will allow you show your kids the property differences of oil and water with a glowing experiment. You and your kids will be excited to create a glowing magical world with oil and water.

Head on over to Growing a Jeweled Rose to learn exactly how to create this magical experiment at home.

Check out just why oil and water are so different below. While you and your kids create the magical glowing world you can share all your knowledge of oil and water and their similar yet different properties.

Oil and Water:

Oil and water are two liquids that are immiscible, meaning they will not mix together. Liquids tend to be immiscible when the force of attraction between the molecules of the same liquid is greater than the force of attraction between the two different liquids.

Although this experiment uses the same volume of oil as water, the two liquids have different masses and therefore, different densities. Density is a measure of how much of a substance is contained in a specific volume of liquid. A liquid that is less dense than water will float on the water; a liquid that has a greater density will sink.

To gain an understanding of density, think of two zippered plastic bags of the same size (same volume). Imagine that one bag contains 10 marbles and the other 20 marbles. The bag containing 20 marbles is denser than the bag containing 10 marbles because it contains more material – even though it is the same material. This analogy describes the relative densities of different concentrations of the same substance.

Also, imagine that there is a third bag containing 10 very large marbles. The volume of the material is the same, the number of molecules (marbles) are the same but again, the bag of large marbles contains more material – it has a greater mass and so a greater density. This analogy represents the experiment above since two different materials are used.

The objects added to the container will float at different levels according to their density. If the density of the object is similar to that of water, the object will float in the water. If similar to the oil, the object will float in the oil.

What does it matter?

Getting oil and water to mix is at the very heart of cleaning dishes and clothes. A lot of agents that make dishes and clothes dirty are greasy or contain oil. Water alone is not attracted to these compounds. However, because a detergent has one end that is attracted to oil-like molecules, detergents tend to bind to dirt, grease and oil. The other half of the detergent binds to water molecules, allowing the soiling agent to be washed away.


Turn Milk in to Plastic: Science Experiment

Science is such an interesting subject. So many things in our world are un-explainable to the naked eye, but if you apply a little science to what seems to be an amazing miracle, voila, you have the perfect explanation. This month we are sure that every mom and dad is beginning to feel the fear of summer. The Boredom. Boredom is synonymous with summer. Which doesn’t make sense, since there is so much to do. But boredom happens, and there are ways to bust that boredom during the summer months. This incredibly fun science experiment is the perfect way to bust the boredom of summer.

This fun science experiment comes from Sarah at How Wee Learn. How Wee Learn is a fantastic website with lots of ways to teach your kids from home. Whether they are preschool age, or school age. Kids learn best when parents get involved, so lets get involved! Let’s impress those kids with some out of this world experiments with milk and vinegar. How can milk and vinegar be so cool? Go check out the full tutorial from How Wee Learn and you will see the most amazing experiment where milk will actually turn in to PLASTIC!!

Science in the World: NASA’s Kepler Mission

In July the world was witness to a great discovery, the Kepler NASA mission delivered incredible images of the incredible discoveries it has been making. Do you and your boys know anything about the incredible discoveries of the Kepler mission? Here is a rundown of the Kepler Mission’s objectives:

Kepler mission

The Kepler Mission’s main objective is to identify and explore the structure and the diversity of the planetary systems. It does this by surveying large star systems and sending back images to NASA for a better and deeper understanding.

To determine if there are inhabitable plants outside of the planet earth in various star systems.

Determine the size and shapes of these planetary orbits.

Estimate the number of planets there are in multiple-star systems.

Identify the members of various star systems.

This mission is accomplished through several different facets including imaging. If you and your kids want to follow along with this incredible mission please visit the Kepler Mission page. You can also learn more about the technologies at use to bring us these incredible discoveries and how they have developed over the years.
