I’ve bought a book called Garden Wizardry for Kids. This is the first project we have done from the book. It’s a ‘Grow Sweet Potatoes’ project that is pretty simple and the kids love it.
All you need are two glass jars, some toothpicks and warm water. Push the toothpicks into the Potatoes and suspend them in the jar. Then fill with warm water. We started with four Sweet Potatoes and only two of them sprouted. But once they did their roots began growing very quickly. Jackson, my four year old, checked it every day and was very excited to see the new growth. Then, when the root system is quite large, the tops start to produce leaves.
I think if you do the project when the weather is warm outside you can then plant the tubers in the garden and hope for the best (depending on where you live). But as we’re still in Winter here I might have to discard them. But, just for entertainment value and a great visual aid to learning about roots and how they grow, this is definitely a great project to try.
