Can these dinos survive the ice age? 

Try this STEM Frozen Dinosaur activity and see if the children can set them free. Use spray bottles, droppers, and other small tools to keep their hands busy and strengthen their fine motor skills. You can also use this activity to help children identify their colors. Have them start with one frozen dino-colored block and work their way to the rest. Perfect for preschoolers! #Early_Childhood_Educators can use this activity to get young children excited about science and engage them in scientific thinking. Ask questions and encourage them to make predictions about what will happen when you place the trays in the freezer and then again before you spray the vinegar.
