Muddy Mats Properties of Matter

Our  second grade engineers received a challenge today from Mrs. Blizzard she needs for us to engineer mats for our building. She is concerned that with our garden we may bring too much water into the building.  She needs mats that soak up water, don't leak and won't slip on our floors.  To accomplish this task we started today by looking at the properties of water with a penny and water drop experiment.
