Beautiful digital art you could display in your classroom to facilitate discussion about global warming. You could present one of images and ask the students what they think it's trying to convey, no text is needed to spark discussion. Great way to get students interested and engaged in the topic.
Henrietta Harris is an artist and illustrator from New Zealand who has created a series of seemingly unfinished portraits. Each drawing is a portrait with the subjects face missing — instead, the crisp black and white images are focused on fine lines and clean shapes. The hair on the subjects is incredibly detailed but the facial area of the image is completely blank. For more of her work, check out Harris’ website.
