Why is the sky blue? What makes a wheel turn? How do airplanes fly?  These questions show a kid’s natural curiosity of the world around them. Science is an excellent tool to help kids strategically find the answers to their many questions. Here at JM Cremp’s, we specialize in developing the adventurous and inquisitive minds of children. We highly recommend these great science kits for kids and simple science projects to encourage the learning process.

Science experiments don’t have to be complicated or expensive. This simple science project for kids uses materials that are found in most kitchens and can be completed in a few minutes. It is easy and safe, so it is perfect for kids of all ages.  So call in the little mad scientists and let’s get started.

The 3 Layer Float

Have you ever wondered why wood floats and rocks sink? The answer is density. Density is simply the measurement of how solid something is. This experiment will show the different density of 3 substances and 3 objects.

Gather Your Materials:

• Oil
• Water
• Honey
• Grape
• Coin
• Cork
• Tall Clear Cup

Note: Corn syrup will work as a substitute for honey. Don’t have a cork handy? Try a small piece of wood or a leaf instead.

Begin the Science Experiment Procedure:

1.    Fill 1/3 of the tall clear cup with honey.
2.    Fill the next third with oil.
3.    Fill the last third with water.
4.    Wait a minute and let all three substances settle.
5.    Carefully drop in the coin, then the grape and then the cork.

Results and Observations:

Answer these questions as you make your observations:

1.    What layer is the water?
2.    What substance settled on top?
3.    What happened to the coin?
4.    What happened to the grape?
5.    What happened to the cork?

Now that you have made your observations it’s time to determine the results. Discuss these questions to reach a conclusion:
1.    What substance has the highest density? (bottom liquid)
2.    What substance has the lowest density? (top liquid)
3.    What object has a higher density than honey?
4.    What objects have a higher density than water?
5.    What object has the lowest density?

For a little extra fun, stir the contents of the glass and watch what happens!

We think the words learning and fun should always be in the same sentence. From mechanical science to chemistry, kids science activities are a great way to keep the fun in learning.  If you are a homeschooling family, this is a great family science experiment since you can involve both younger and older students.
