Fossil Clay Recipe
4 cups baking soda
2 cups corn starch
2 1/2 cups water
Makes enough clay for about 20
Use small rubber
dinosaurs, tiny seashells, plastic leaves or fern to
make impressions in the clay. Let impressions sit
for 24 hours or bake impressions on lightly greased cookie
sheet in 200° oven for two hours.
On the day we do
this we fill sand table with rice and bury a wooden
dinosaur puzzle in the rice. Give students brushes
and small garden tools and let them uncover the pieces and
put dinosaur together.
