We have been learning that scientists observe, ask questions, experiment, and find answers. After using our senses to describe a marshmallow, we dumped four marshmallows in four liquids (water, vinegar, cranberry juice, and soda). We learned and defined the big science word DISSOLVE. We made a hypothesis about which marshmallow would dissolve the fastest. Most of us guessed soda, but after two days of observations, we learned that vinegar dissolved the marshmallow the fastest. Cranberry juice and soda dissolved the marshmallow the slowest, because those liquids are full of sugar – just like a marshmallow.
