What kind of liquid is this? What does it look like? What does it feel like? Examine and investigate all of its different properties: color, smell, feel, and more! First graders and second graders become liquid detectives as they use their observational skills to talk about physical science in the real world. In this hands-on science activity, they will investigate, describe, and record information about a mystery liquid. Finally, everyone can share what they have recorded and discovered with the rest of the class.
