Have you ever wondered what makes you uniquely you? From your eye color to your hair texture, many of your traits are guided by DNA – the tiny instruction manual found inside your cells. Today, I’m sharing a Strawberry DNA Extraction activity from our Human Biology Family Unit Study that lets kids see DNA for themselves with just a few simple supplies!
In this hands-on experiment, children will mash strawberries, mix a few everyday ingredients, and watch as white, stringy strands of DNA appear right before their eyes. It’s such an exciting way to explore genetics and cell biology! Best of all, it feels more like a science magic trick than a lesson.
This activity fits into our exploration of DNA and genetics, where kids discover how traits are inherited and learn why DNA is often called the “blueprint of life.” You can read more about the Human Biology Family Unit study and explore all of the engaging, hands-on activities included in this blog post or grab the complete unit in the How Wee Learn Shop.
Extracting Strawberry DNA
Did you know that each and every one of our Family Unit Studies includes: Geography, History, Science, Social Studies, Music, Art, Health, Literacy, and Math?
Well, they do! You can feel great knowing you are covering all academic subjects in an engaging, meaningful, and hands-on way.
The activity I’m sharing with you today is all about science and discovery. In this Strawberry DNA Extraction experiment, children get the incredible opportunity to see DNA with their own eyes using just a few simple household supplies. It’s hands-on, fascinating, and a wonderful way to spark curiosity about genetics, cells, and what makes every living thing unique.

See DNA With Your Own Eyes!
Start by gathering your materials:
- 2-3 strawberries
- a sealable plastic bag
- water
- dish soap
- salt
- a coffee filter or paper towel
- a clear cup or glass
- rubbing alcohol
Remove the green tops from the strawberries, then place them in the plastic bag. Seal the bag and gently squish the strawberries until they are soft and mushy. Kids always love this part!
Next, add 100 mL of water, a few drops of dish soap, and a pinch of salt to the bag. Seal it again and gently mix everything together. The soap helps break open the cells, while the salt helps the DNA clump together.
Place a coffee filter or a paper towel over a cup or glass, then carefully pour the strawberry mixture through it. Let the liquid drip into the cup below, leaving the larger strawberry pieces behind.
Now for the exciting part! Slowly pour rubbing alcohol into the cup, creating a layer on top of the strawberry liquid. Try not to mix the two layers together.
Watch closely as white, cloudy strands begin to appear where the two layers meet. Those stringy strands are DNA! You can even lift some out using a toothpick!
Take a few moments to observe what happened and talk about what you see. What does the DNA look like? Does it look the way you expected?
For even more scientific fun, try repeating the experiment with other fruits, such as bananas or kiwis, then compare the results.
And there you have it – your very own Strawberry DNA Extraction Experiment!
Keep Exploring the Human Body
There’s something truly amazing about seeing DNA with your own eyes! What can seem like a complicated scientific concept suddenly becomes real when children watch those tiny, white strands appear right in front of them. It’s one of those hands-on learning moments that leaves a lasting impression.
Activities like this help children connect with science in a meaningful way. As they experiment, observe, and ask questions, they begin to understand that science isn’t just something found in books – it’s happening all around them, even inside a simple strawberry!
If your family enjoyed this activity, be sure to explore the full Human Biology Family Unit Study. It’s packed with engaging experiments, creative projects, and fascinating discoveries that help children learn more about the incredible human body and how it works.
