A Germ’s Journey by Katie Laird and Sarah Younie
The journey, from the toilet seat to the tummy (and out again!), explores the concepts of germs being invisible to the naked eye, multiplying and causing illness. By placing their warm hands on the thermochromic patches, the multiplying germs are revealed. The simple, bright and bold illustrations allow children to develop an understanding of science and health from a young age, while having fun in the process.
