Pumpkin Science Experiments

All you need for theis fun halloween activity are a few simple materials you may already have on hand:

  • pumpkin (s) – real or artificial, any size!
  • Carving knife to cut out top
  • Baking soda
  • Vinegar
  • Optional: Dish soap
  • Food coloring
  • Plate or tray to catch the “lava”

Personally, I prefer to skip the taking out all the innerds and use an artificial pumpkin, but this works with real pumpkins too. Carefully use your knife to cut off the top of your pumpkin so you can get to the inner opening. You can use any size pumpkin, just remember the bigger the pumpkin the more material you will need to get the huge WOW effect.

Pumpkin Science

Place the pumpkin or pumpkins on a tray or plate to catch the lava mess. Now fill the inside of the pumpkin about halfway with baking soda. Add a few drops of dish soap to the baking soda and food coloring if you’d like.

My kids were SO excited to see the green bubbly lava flow over the pumpkin and begin pooling on the dish.

Halloween Activities

You can keep adding vinegar until the chemical reaction of the acid and base (baking soda and vinegar) is done.

Then you can always start it all over with a new color! My kids wanted to do this again and again. And it’s so simple because it uses common household items so I was happy to keep their intrest in science keep going!

Baking Soda and Vinegar Experiment

These common kitchen ingredients combine in this vinegar and baking soda experiment to form a chemical reaction where carbon dioxide is produced. The CO2 gas pushes the substance out as it takes up more room. The dish soap creates bubbles and allows it to ooze and flow more. I love making science FUN!

  • Hello there!
    I’m thinking about trying this activity out with some students of mine but I have no idea about quantity. Could you help me telling how much of vinegar and baking powder will I need to get

    • It all depends on the size of your pumpkin….. I like to fil it 1/2 way with baking soda for a really great effect
