What: Printing and painting with food dye, using carrots cut into shapes as stampers and “brushes”.
How: Cut the carrots on a couple of different angles and at different sizes – you should be able to get small circles, big circles, ovals, irregular/pointy ovals, and even a rectangle or two of various proportions. I also cut one carrot unevenly so that it stamped a half circle, and cut another to give a more triangular result. Take plastic or styrofoam meat/fruit trays and put a few drops of different colours of food dye on them. Rub the carrots in the dye and stamp them or roll them or “brush” them on the page to make patterns and pictures.
Extras: Careful choice of dyes means you get to talk about mixing colours – and the colours WILL mix! You can focus on making patterns of whatever level of complexity your kids are up to, do it “wrapping paper” style. Or use the shapes to build up a picture and talk about what shapes are in the picture or make up different parts of the picture. I would have liked to talk about what happens when you roll – that mental translation from a 3D object to what its sides look like in a 2D form as you roll it across the page – but neither kid 4 or kid 6 was quite up for that. At first (and mostly) they just used the carrots like pencils, but as they went along they began to see that they could do more than that.
