Puffy fat cooked gingerbread men!

Kaya brought fresh eggs from his hens for the recipe.

This week our inquiry question about food changes is why do gingerbread men get bigger when they cook? To find out we baked gingerbread men with our Room 11 buddies and compared the sizes. The cooked gingerbread men were bigger and higher! Poppy thinks that the heat makes the mixed up ingredients puff up. Our next step is to mix the baking soda with cold water and then mix some with hot water to see what happens next!
