We LOVE the 4th of July and we also love fizzy experiments! This fizzy ice stars experiment is fun for kids of all ages and is great for a hot summer day! You’ll love how easy it is to do this activity and your kids will think you are the best for setting this activity up for them!
Fizzy Ice Stars Materials
This activity is very simple and is a great science activity for children! Here’s what you need:
- star ice cube tray (found at The Dollar Store or on Amazon here)
- 1 cup water
- food coloring
- 1/2 cup baking soda
- bowl of vinegar
- dropper
- tray
Fizzy Ice Stars Directions
- To start, mix 1 cup of water with 1/2 cup of baking soda.
- Next, add a few drops of food coloring and mix.
- Then pour the mixture into the star ice cube tray. You may have to scoop in the baking soda, since it tends to sit at the bottom of the mixture.
- Lastly, put the tray in the freezer.
- When its frozen, pop the stars out of the mold and place them on a tray or plate.
Before beginning the activity, ask your child some questions to help them think like a scientist!
- What do you think will happen when we put vinegar on top of the stars?
- How much vinegar should we put on there?
Then take the dropper, fill it with vinegar, and release it over the frozen stars. Watch what happens!
Using a dropper is so great for practicing fine motor skills and building hand strength!
We saw lots and lots of fizz! It was cool to listen to this experiment.
I love this open-ended activity because you can encourage the kids to try their ideas. Maybe they want to add more baking soda on top of the star, or add more vinegar, or add warm water…the children get to think like a scientist and try their ideas out!
Clean up is easy for this activity! Just pour the liquid down a sink and wipe up any vinegar that may have splashed on the table.
