Grow a windowsill garden using food scraps such as carrot tops and shrivelled potatoes. Observe how these scraps grow roots and shoots to form a new plant. Talk about what plants need in order to grow well (such as light and water) and set up a control to see what happens to scraps which don’t get these essentials. Describe and record observations.
Note: Food scraps that will grow easily on a windowsill include pineapple, onions, potatoes, celery, garlic, onions and carrot tops.
