Lettuce Grow Together!
At Carnegie Science Center, we recognize that every child should have equal access to an environment that fosters curiosity, encourages the desire to learn, and explores all realms of science. We’ve teamed up with Growing Great and Del Monte Foods, Inc., in their National STEM Education Initiative to educate students and families on the science of planting, growing, and eating healthy foods.
Our Lettuce Grow Together! program will feature storytimes, experiments, and activities exploring the science behind fruits and vegetables and the importance of nutrition — all while helping to inspire healthy eaters.
We want to hear from you! Share your experience supporting learning activities in your home over the past year with a brief survey from GrowingGreat Veggies & Fruits: A National STEM Education Program. This survey is also available in Spanish.

DO: Make your own butter at home with a few simple ingredients!
Homemade Butter Activity
- 1/3 cup heavy whipping cream
- 1/4 tsp salt
- Marbles (apprx. 6–7)
- Plastic container with tight lid (screw-top is best!)
- Strainer or dishtowel
- Gather all your materials!
- Measure out the heavy whipping cream and salt and pour into the container.
- Add the glass marbles to the container with the cream and salt. Six to seven marbles are appropriate for this recipe but add more if you scale up.
- Place the lid securely onto your container. A screw-top container is best since it makes a tight seal. Make sure that your container and lid are not fragile, since the marbles will be hitting against them.
- Make the butter! Vigorously shake the container with the marbles. You’ll need to shake for about 10 minutes, or until the butter reaches a whipped consistency. The marbles help to churn the cream into butter!
- Once the butter has reached a whipped texture, give it a taste! Does it taste different than the butter you’ve had before? You can pour off the extra liquid. This is buttermilk, which can be saved to make pancakes or other baked goods!
- Once you’ve made your butter, take out the marbles before putting it away. Place the marbles in a fine-mesh strainer or dishtowel and run under water until clean.
- Now that you’ve made your butter, you can use it just like the stuff from the store! You can enjoy a small amount on top of steamed vegetables! If not using all your butter at once, you can store it in the fridge for an additional day or two.
Safety: Marbles can be a choking hazard – use caution around young children!
