Food Science Experiments for Kids

The kitchen holds a special place in the home and the heart. It’s where meals and memories are made, where families bond over food, and where lessons are passed down to the next generation. Kids can be taught about recipes, cooking techniques, nutrition, and more in the comfort of their home kitchen through food science experiments.

From chemical reactions to physical changes, the kitchen is a perfect laboratory for kids to explore science. Here’s why that education is so important, and how you can use food science experiments for kids to explore science with your children!

Food Science Experiments for Kids

Nurturing kids’ learning in science is crucial for their academic and personal development. Science education can help kids develop critical thinking, problem-solving, and analytical skills. This knowledge is not only essential for success in science-related careers, but is also important in everyday life. The ability to observe, hypothesize, experiment, and draw conclusions can help them become better decision-makers.

Additionally, science education can ignite kids’ curiosity and foster a love of learning, which can lead to a lifetime of intellectual growth and personal fulfillment. Encouraging kids’ interest in science can help them become more knowledgeable, creative, and responsible members of society. So if you’re ready to let learning take root in your children, read on for fun food science experiments you can conduct in your own kitchen!

Ready to conduct science experiments in the comfort of your own kitchen? Here are some of the best science experiments with food:

Regrowing from food Scraps

Teach your kids about plant growth and gardening—and grow new food from scraps—with this useful regrowing experiment! Take the ends of roots you’ve chopped off of vegetables, and put them in a cup with water. Place your roots where they can get some sun, and have your child help you change the water each day and monitor progress. In 3 to 5 days, you will start to notice new growth. Once your plants are tall enough, harvest your food—and consider starting the experiment over again!

You can try this experiment with:

  • Onions (Green, Spring, White, Red, or Yellow)
  • Leeks
  • Fennel
  • Lemongrass
  • Celery
  • Cabbage
  • Bok Choy
  • Romaine Lettuce
  • Garlic
  • Pineapple

This is a great opportunity for your child to observe the plant life cycle up close. It also provides you with more food, reduces food waste by utilizing scraps, and can promote an interest in gardening.


Another fun way to reuse food scraps is to refresh old clothes with your own natural dyes. Use food scraps with lots of natural color, such as:

  • Beets
  • Red Cabbage
  • Onion skins
  • Pomegranate skins
  • Avocado skins
  • Tomato skins, cores or tops
  • Carrot skins
  • Strawberry tops
  • Wilted spinach or herbs
  • Turmeric skins

Soak your food scraps in warm water until the water starts to become colored, then bring it to a boil and let it simmer for an hour. Then let it cool, strain out the food scraps, and use your natural dye as you please.

This experiment can teach kids about colors and pigmentation, and can make use of food waste while giving new life to old fabrics. Note that natural dyes work best with natural fibers like cotton, and remember that this experiment can get messy, so parental supervision is important.


A classic science experiment involving kitchen items is the well-known baking soda and vinegar volcano! Kids can learn about chemical reactions while seeing how baking soda and vinegar interact when combined. You can also add red food coloring to create a lava effect, and pile sand, graham cracker crumbs, or similar substances in a volcano shape to add to the illusion.


Teach your kids about transpiration, osmosis, and more with a simple kitchen science experiment using celery. Place celery stalks in dyed water (dyed from food dye or colorful food scraps) and observe how the colored water is transported through the veins and leaves of the celery.

You can also conduct this experiment with white roses to see the dyed water change the color of the rose petals. To make this experiment extra fun, cut the stem of a white rose into quarters vertically and place each stem ending in a cup of different colored water. This will give you a beautiful multicolored rose!


A fun experiment that takes place over a longer time span is seed germination. Using seeds, water, a paper towel, and a resealable plastic bag, you can demonstrate how seeds germinate over time. As your kids see the changes each day and watch the seeds sprout, they will get fascinating insight into biological processes. This is also a great starting point to get your kids interested in gardening, agriculture, and/or food science.

Have Fun and Stay Curious

By conducting food science experiments, children can learn about the world around them while having fun in the process. Whether it’s observing the plant life cycle, dyeing clothes with natural pigments, creating a baking soda and vinegar volcano, or witnessing seed germination, these kitchen adventures will captivate young minds about fruits and vegetables and ignite their curiosity about nutrition. So step into the kitchen and embark on a journey of discovery with your kids, as they explore the fascinating world of food science through hands-on experiments.


We at the SLO Food Bank believe that everyone has the right to nutritious food. That’s why we work hard to ensure access to fresh food for everyone in our community. We structure our programs in a few different ways to make fresh produce more accessible and affordable for those who need it. We also promote food assistance programs like CalFresh, while also hosting food distributions in the most rural areas of our county, where a grocery store may be more than 50 miles away.

With our network of community partners in San Luis Obispo, we strive to alleviate hunger and to build a healthier community. If you’re in the area, check out our Food Locator to find food sources near you, or support our cause through volunteer opportunities or donations, if you are able to give. With reliable access to wholesome food, we are all healthier, happier, and more productive members of our communities. Donate today to help us bring health and happiness to San Luis Obispo County!
