YOU WILL NEED:
- Black card stock or heavyweight paper
- Baking Soda
- Vinegar
- Spray bottle or pipette
- Craft Paint
- Cups and mixing utensils
- Paintbrushes
While you have the baking soda out, make these fizzing moon rocks for moon theme science and STEM!

HOW TO MAKE BAKING SODA PAINT
1: Fill up a small spray bottle with vinegar and set aside.
2: In a few separate cups, mix a 1/2 tablespoon of paint with a tablespoon of baking soda.

3: Draw a circle on a piece of black card stock.

4: Use the paint brushes to paint the Moon with different shades of blue (the paint should be thick). Let your Moon dry and draw a few stars around it with a white crayon or marker.


5: Once the moon painting is completely dry, use the spray bottle to squirt vinegar onto it and watch it fizz.

Go ahead and make a whole solar system of fizzy Moons, planets, stars, and sun!
FIZZY PAINT TIPS
As I mentioned above, you want to make sure the paint is on the thicker side when you mix the ingredients together. Generally a 1:1 ratio is good.
Also, make sure to spread the paint on in a thick layer for best fizzy results. Additionally, you want to make sure your masterpiece moon is dry before working with the vinegar.
Extend this Moon theme STEAM activity by cutting out the different shapes for the phases of the Moon and painting them with the baking soda paint as well. You can read a full description here… phases of the moon.

THE SCIENCE OF BAKING SODA PAINT
The science behind this fizzy paint moon craft is the chemical reaction that occurs between the baking soda and the vinegar!
Baking soda is a base, and vinegar is an acid. When the two combine, they make a gas called carbon dioxide. You can hear the fizz, see the bubbles, and even feel the fizz if you hold your hand close to the surface of the paper.
Combine the simple science of this chemical reaction with a cool art project for STEAM. Science + Art = STEAM!

I love this Fizzy Moon Painting, but I wanted to know if I did this in my classroom, how long does it take for the baking soda to dry?
You will probably want to give it overnight but it also depends on how thick the kids apply it too!
