The Benefit Of Science Experiments For Kids

My children are obsessed with kitchen experiments. I personally love these kids’ activities as well since it gives me the perfect opportunity to combine fun with education.

We use the chance to read a subject-related book first. Then we talk about what we like to accomplish with our fun activity and the science behind it.

This gives you the opportunity to add language-building activities like discussions, conversations, and new words. Overall this will help with reading, writing, and children’s conversation skills.

You can find those and many more benefits of science experiments for kids and toddlers here.

Why Did I Pick This STEM Activity

In general, my kid’s activities need to be:

  • easy to set up
  • manageable for different age groups

As many of you know by now I have three children in the age group of 2,4 and 8. Therefore my family projects are simple to prepare and easy to implement.

I choose kid’s projects where I can simply change the difficulty level to provide challenges and fun for every age group.

Especially about this project I love the fact that it is perfect in a classroom setting. It also gives children the chance to explore the knowledge with all senses while helping step by step along the way.

As mentioned before, I advise explaining to your children upfront the science behind this dancing grapes experiment. That way they know what they looking for!

Dancing Grapes Instruction

Follow these simple steps to get your grapes magically to dance:

Step 1: Prepare your glass container

Fill the vase 3/4th with bubble water. This will not work with regular tap water!

Step 2: Prepare your grapes

Wash the grapes and remove them from the stencils.

Step 3: Add grapes

Drop a handful of grapes in sparkling water.

Step 4: Let the grapes dance

Watch the grapes dance.

Grape Experiment Tips

  • Instead of dancing grapes try dancing raisins or dancing corn. They are just as fun!
  • No reason to waste food, the grapes can still be eaten after the experiment.
  • Grapes can be a choking hazard for young toddlers and babies. Therefore I recommend this activity only for children age 3 and up.

Dancing Grapes Science Experiment Theory:

Seltzer water contains carbon dioxide (CO2) which is essential to this STEM activity!

Since grapes are heavier than water, they automatically sink to the bottom of our glass jar.

As you can easily see in the video carbon dioxide bubbles attach quickly to the grapes and make them rise.

On top, the bubbles pop, and the grapes sink back to the bottom. The process repeats itself until all the carbon dioxide is used.

As a result, the water turns flat and tastes like tap water. Take a sip and try it yourself!

It s the same process when you leave any type of soda bottle open without putting the screw back on. The carbon dioxide will vanish and it starts to taste flat since the carbon dioxide is gone!

Frequently Asked Questions

Do Grapes Float?

Before you start with your floating grapes experiment you should let your children think about it and make their own hypothesis.

Let them discuss whether grapes sink or float and try to come up with an explanation.

To answer our question, do grapes float? The fact is that grapes sink in regular tap water.

Only the carbon dioxide (CO2) in the seltzer water makes them float. When the CO2 is gone it will sink again to the bottom of the glass.

Do Grapes Fizz in Soda?

To make this easy dancing grapes experiment more interesting, fill one container with seltzer water and the other one with soda, preferably Sprite.

You will experiment with the unpeeled grapes also fizz in soda (Sprite).

Soda also has tiny carbon dioxide (CO2) bubbles to pull the grapes to the top of the liquid.
