Regrow kitchen scraps
Re-growing vegetable scraps in water is a fun science experiment to do with the kids that can be tasty too. Below are a few examples to try.
Lettuce and celery
Place the end of a lettuce or celery in a glass or saucer and add a small amount of water. Ensure the end of the lettuce or celery is submerged. Leave on a sunny windowsill and watch it re-grow over the coming days and weeks. Make sure the water doesn't dry up and change the water every day or so.
Beetroot and carrot
Cut the top off a beetroot, put it in a shallow tray of water. You'll notice the beetroot greens starting to grow after a few days, which you can use in salads.
You can use the same method for carrots. Carrot top greens are nutritious, high in potassium and vitamin K.
