About this product

Ginormous Hatchin' Grow Dino EggThis 4.5 in dinosaur egg will grow into nearly a 12 inch fully grown dinosaur. Place the Ginormous Hatchin' Grow Dino in a large container of cool water. Make sure the egg is fully submerged. Allow egg to sit in the water undisturbed for 48-72 hours. During this time, the Ginormous Hatchin' Grow Dino will break out of its shell & begin to grow! Once the dino has fully broken out of its shell, replace the old water with fresh water & watch the dino grow & grow! There are assorted dinosaurs, yours will be chosen at random from stock. Ages 5 & upGrowing 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.
