Welch’s Paint it Purple Activity:Be a Color Scientist

welchlogoWelch’s 100% Grape Juice is celebrating National Nutrition Month. We have been drinking Welch’s juice for many years now. I like it because it contains low sugar and the kids love juice that tastes good. Welch’s is made with Concord grapes.

Did you know you can do some really fun activities with Welch’s Grape Juice? We tried “The Color Scientist” activity and Nolan had a blast. This activity will allow your child to experiment in the kitchen and expand her science knowledge, and make some liquids change color. They can also learn scientific terms such as “acid” and “base”, “chemical reaction” and “indicator.” The directions are below and make sure to watch our video to see the surprise reaction we had at the end.

BE A COLOR SCIENTIST ACTIVITY

What You Need:

Welch’s Grape Juice

Spiral notebook for a Science Journal or lined paper to record steps and observations

Pencil

Crayons

Water

Vinegar

A stirring spoon

Soap

Jars or glasses

Baking soda

Lemon juice

What You Do:

1. Pour Welch’s Grape Juice in two glasses or jars.

2. Give her some grape juice in two jars or glasses. Explain to her that she will be experimenting to see if she can make the purple grape juice change color. It will look like a magic trick, but it will really be a chemical reaction – a change that takes place when certain substances come into contact with one another.

3. Have her pour a little lemon juice into one of the glasses filled with grape juice.  In her Science Journal or on the sheet of paper, help her record what she mixed together (grape juice and lemon juice) and then have her record what happened.  Have her draw a picture of what she saw.

4. Explain to her that the lemon juice is an acid.  All acids will turn a blue liquid or indicator, red. Tell her that the grape juice is called an indicator because it will indicate (or tell) whether another liquid is an acid.

5. Next, add two spoons of baking soda to the second glass or jar of grape juice. Again, have her record what she mixed together and what the results were. This time the grape juice should turn green.

6. Explain to her that the baking soda is the opposite of an acid. It is what is known as a base.  A base will change the color of an indicator from blue to green.

7. Now, see what happens if you add some baking soda to the red liquid (the grape juice and lemon juice). It should change back to purple – the indicator color for neutral. Ask her what she thinks would happen if lemon juice was added to the green liquid?  Make sure she doesn’t drink the grape juice she’s been experimenting with, or she will be in for a not-so-tasty treat!

I recommend you should go try Welch’s Family Vine Tool on their website. Welch’s is helping spreading heart healthy awareness, which enables families to trace their personal health histories and share the results among relatives.

The Grape Science Center is a valuable resource to learn about the growing Concord grape research in areas like heart health, cognitive health, immune system health and more. For more information on the science behind the Concord grape’s health benefits, visit the Grape Science Center at www.grapescience.com.

In addition to promoting heart healthfulness, Welch’s has prepared recipes and other tips for creating tasty meals and snacks with vibrantly colored fruit. Find these and more at the Welch’s Recipe Box.

I wrote this review while participating in a blog tour by Mom Central Consulting on behalf of Welch’s and received a product sample to facilitate my review and a gift code to thank me for taking the time to participate.

  1. How very cool! I’m a science geek as well as a mom, and I love kitchen chemistry experiments!

  2. Great activity! I will be doing this with my little guys next week!
