Preschool Science Experiment: Sparkly Fizzing Rainbow

By -
Welcome spring with a sparkly fizzing rainbow science experiment!!  This is super fun science project is perfect for inside on a rainy day or outside in the sun!



Last week I shared our awesome Rainbow Volcano.  When we made it, we had some extra colored baking soda dough, so we decided to arrange it into a pan like a rainbow!



The kids loved it!  I loved it too...I still can't get over the colorful baking soda!  My kiddos knew that the baking soda would react with vinegar from our last experiment but, before they made it erupt, they wanted to do one more thing...




Can you guess? 

They wanted to make it sparkle!!

So we dumped in loads of sparkly glitter!!  

Side-note:  This is the perfect place for glitter-phobic parents and teachers!  The glitter is completely contained, and when you're done, just wash it down the sink!  ;D

Then, of course, we added vinegar to make it erupt, fizz, and sparkle even more!  We used pipettes because it lets the activity last longer while strengthening fine motor control and the small muscles in their hands.



You can make your own Sparkly Fizzing Rainbow too!!  You need these

Simple Supplies:

* Colored Baking Soda Dough
(click here for instructions)

* vinegar and cups to put it in

* pipettes (optional, but recommended!)

* pan to contain the rainbow and the sparkly fizzy eruptions


Easy How-To:

1- Arrange your baking soda dough in the pan to make a rainbow!  You can put the colors in the same order you find in nature (red, orange, yellow, green, blue, indigo, and violet), or just let your kiddos choose the order!

2- Use pipettes to add vinegar!  Ask your children what they think will happen when you mix the vinegar and the colored baking soda dough.  Ask them why!  Then let them get to work!!  They will see the vinegar and baking soda react to release carbon dioxide.  Carbon dioxide is a gas and makes bubbles wherever the other two reactants touch!

Note:  About half of the kiddos in our preschool group had never used pipettes before.  To make sure everyone had a successful experience, we practiced using the pipettes with colored water first.  Once everyone could successfully transfer the water, we were ready for the vinegar!




It wasn't long before we had a few extra friends join in the fun...





I hope you enjoy rainbow science projects and activities because we are on a bit of a roll!  And if you make a sparkly fizzy rainbow, I'd love to see it!!  Feel free to leave a comment here or on the PreschoolPowolPackets Facebook page sharing your rainbow science experiment fun!

Science Experiment: Elephant Toothpaste

Update: "Elephant toothpaste" is a science experiment that I used to do with my high school students.  It is a strong multi-sensory demonstration that goes great with a lot of chemistry concepts. It is also very popular with preschoolers and homeschoolers!  The internet loves it too! It has now been read by more than 3.9 million people! This was the post that started the trend on science activity sites across the internet and "irl!"  Thank you for being here...I hope you enjoy it as well!  💕  This exciting science experiment works great in a discussion on reactions, as a demonstration, or as an actual experiment. We've also done seasonal twists with "elephant toothpaste" like making it in a pumpkin and using it for " reindeer toothpaste !" To use it as a science project, perform it once with your child, then ask your child what might happen if you changed the amounts or left out an ingredient.  Any time you experiment

This sensory lesson includes a kindness activity for kids that is short and sweet,  and makes teaching kindness a beautiful thing! Learning to use kind words with our friends is one friendship lesson that I think we can never cover enough...kids always need reminding (sometimes adults do too)!  You will need these simple supplies for the kindness activity: cotton balls, course sandpaper, cup, Should I Share My Ice-Cream by Mo Willems Directly teaching good friendship skills, like using kind words, serves two purposes: 1- You can refer to the lesson when someone forgets or needs reminding, and 2- These skills are not intuitive for all preschoolers. This is a perfect age to bring empathy and kindness to their attention and help them cultivate these skills! You can use this lesson plan exactly as I did it with our kiddos, or adapt it to fit your group! 1- Read  Should I Share My Ice-Cream  by Mo Willems.   {Image below is an Amazon Affiliate Link:} D

Crazy Cool Giraffe Science Experiment

Do you know what color giraffe skin is? Today we're using a capillary action science experiment to make our own giraffe skins in this fun giraffe science experiment project! (Read on...I'll tell you the color in a moment! AND I have a few more fun giraffe facts at the end! Anyway, go on and make a guess before you see the answer!) Fun Spot  Giraffe  Fact:  There are four different giraffe species:  the Masai Giraffe, the Rothschild Giraffe, the Somali Giraffe, and the Nigerian Giraffe.  Each has its own unique spot pattern.  Even more unique, every single individual giraffe has a different spot design.  Just like fingerprints on people and stripes on a zebra, spots on a giraffe are unique in every individual! Giraffe skin is mostly grey. (Were you right?) It's also really tough and thick.  The coat is a shade of tan with brown spots or patches.  Male giraffes actually get darker as they get older! To make our "giraffe skin" we're going to us
