Erupting lemon volcano

Lemon volcano experiment worksheet

Start by rolling your lemons to get the juice loosened up. Now cut off the top third and discard. Poke around the inside of the lemon with a craft stick to get those juices flowing.  Set as many lemons as you want to errupt on a large tray or plate. If they don’t stand up, make sure to slice just a little off the bottom so they are nice and steady.

Acid Base Chemical Reaction

Lemon Science Experiment

Add a several drops of food coloring to each lemon. We like to mix it up so the erruption will make lots of pretty colors that will mingle with one another on the tray. So red, orange, blue, purple, teal, pink, etc. And of course we need a yellow – this is a yellow lemon experiment!

Now add in a good squirt of dish soap. We used clear dish soap so as not to affect the color.

Finally dump a heaping tablespoon of baking soda on the opening of each lemon.

Lemon volcano experiment explanation

If you are familiar with the classic volcanos science experiment you are probably wondering – where’s the vinegar?  Well, this experiment shows kids a chemistry reaction between an acid and a base which results in the release of  Carbon Dioxide (also known as CO2). In this lemon experiment the lemon juice (which is filled with citric acid) served as the acid so we had no need for vinegar! So if the acid is lemon and the base is baking soda, why did we have soap in there? Glad you asked. The dish soap helps capture the gas that is released in the chemical reaction so we can see it as bubbles. And just in case you want to see the chemical equation – here you go!
