Read Tacky the Penguin. Next, talk about how penguins like to slide on ice. After that, try your very own experiment to see which toys slide on ice and which dont. Heres what youll need to conduct your own experiment: a shallow pan, water, and 5 (more or less) items to test. Youll also want a pen and paper to make a table showing the results (which items slide and which do not).
