Take science outdoors with a SANDBOX VOLCANO! When the weather is nice, try simple science experiments outside for a real hit with the kids. From pulleys to homemade ice cream, to bursting bags, this baking soda volcano is one of the coolest and easiest science activity for kids. Simple science and STEM activities are perfect for young kids.

BEST SANDBOX VOLCANO ERUPTION EVER!

BAKING SODA SCIENCE

We do love all things that erupt and have been exploring a few different ways to create eruptions while having fun through play. Science that fizzes, pops, erupts, bangs, and explodes are pretty awesome for kids of all ages.

When the weather is nice, it’s an awesome idea to take STEM and science outdoors! Building a sandbox volcano is definitely an outdoor science activity with a quick clean up.

What we really love about science activities or demonstrations like these, is the extra play factor that is organically included. You can see what I mean at the end of this post.

SANDBOX VOLCANO SUPPLIES

Also, take a look at our salt dough volcano project as an alternative!

• sandbox with sand {make sure to try our sand slime too.}
• water
• baking soda
• vinegar
• 16oz water bottle
• food coloring (optional)

*You can also try adding dish soap for an even foamier fizzing eruption. Just a few drops are all that is needed.

SANDBOX VOLCANO SET UP

Fill water bottle about a third full (mix in optional food coloring)

Add about 5 teaspoons of baking soda

Put the cap on until you are ready

Build a sand mountain around the bottle

Uncap the bottle

Pour a good amount, probably a cup of vinegar into the bottle

Get out of the way and watch the huge eruption!

How Did We Get such An Awesome Sandbox Volcano Eruption?

Volume. It was as simple as a good amount of vinegar into a small amount of water filled with baking soda! We repeated it several times to test our theory. 

When the baking soda and the vinegar mix they form a gas called carbon dioxide which then produces the fizzing eruption. The shape of the container helps to shoot the eruption up higher because the gas is easily forced out and up due to the narrow opening.

This chemical reaction occurs because of an acid {the vinegar} mixing with a base {baking soda}. When the two combine the reaction takes place and the gas is created. If you added dish soap, you will notice a more foamy eruption like in our watermelon volcano.

 

We still enjoyed many small sandbox volcano eruptions too! Make sure to check out a complete few different ways to create eruptions to try.

The heavy machines were standing by ready for work!

MAKE SAND SLIME too!

We have been working on simple science concepts. Repeating similar types of experiments builds knowledge and reinforces learning skills. Young children need simple concepts repeated for greater understanding.

Try a few ways and you will be amazed at how much they remember. This will build confidence for new learning experiences and curiosity to try new experiments!
