From small to GINORMOUS! When placed in water this ginormous shark grows up to 19 inches long. Seriously BIG FUN! These sharks are scary looking when full grown! Think of the fun you can have putting that in someone's bathtub! Also, this is a fun way to teach measurement. Can be dried out and then grown again. We tried them and were amazed how big they grew. Put your grow shark in a tub or bucket of cool water and watch it grow! It will keep kids interested in how much they change day to day. Build them a home, they will never dissolve or turn to mush. Sharks come in two colors. Yours will be chosen at random from stock.

Growing animals and other things (brains etc!) that are made to increase in size in water are made up of two polymers. One is poly(vinyl acetate) which keeps the original proportions and shape of the item or creature and the other polymer is polyacrylamide which is the super absorbent polymer. The growing creatures have many teaching applications in science and math, including graphing, drawing conclusions, and measurement using linear, mass and volume. The Growing Creatures Book by Anne Linehan and Betsy Franco details measurement and data collection projects integrating math and science.

Teaching Chemistry with Toys also has science experiments with grow animals.
