Looking for an exciting way to teach your "scientists" about making observations? Have your scientists explore Oobleck using their senses. This activity works great after reading Dr. Seuss' Bartholomew and the Oobleck.
Looking for a quick and easy way to informally assess your students? Use a "windshield check!" Have students raise a clear, buggy, or muddy card to represent their understanding of a concept. Cut and laminate a set for each student.
