Mrs. Elden’s fifth grade Science classes just completed their “Matter and Energy” unit. During this time, they experimented with evaporation by filling up a small cup with water and another cup with water and salt. They noticed that, within several days, the water had evaporated from both cups and the salt was left behind. This introduced a discussion about our Weather unit and the water cycle as well! The classes also conducted an experiment with steel wool in water and steel wool in vinegar to observe physical and chemical changes!
